From 9e727335404ca167348ae25a4ad8f9e50b5bac07 Mon Sep 17 00:00:00 2001
From: Rostislav Pehlivanov <atomnuker@gmail.com>
Date: Wed, 26 Oct 2016 22:15:15 +0100
Subject: [PATCH] Remove the ffserver program and the ffm muxer/demuxer
Also removes url_feof from libavformat.v which should have been
removed long ago and changed the multipart jpeg boundary tag to
ffmpeg rather than ffserver (it's arbitrary).

-ffserver [@var{options}]
-
-@chapter Description
-@c man begin DESCRIPTION
-
-@command{ffserver} is a streaming server for both audio and video.
-It supports several live feeds, streaming from files and time shifting
-on live feeds. You can seek to positions in the past on each live
-feed, provided you specify a big enough feed storage.
-
-@command{ffserver} is configured through a configuration file, which
-is read at startup. If not explicitly specified, it will read from
-@file{/etc/ffserver.conf}.
-
-@command{ffserver} receives prerecorded files or FFM streams from some
-@command{ffmpeg} instance as input, then streams them over
-RTP/RTSP/HTTP.
-
-An @command{ffserver} instance will listen on some port as specified
-in the configuration file. You can launch one or more instances of
-@command{ffmpeg} and send one or more FFM streams to the port where
-ffserver is expecting to receive them. Alternately, you can make
-@command{ffserver} launch such @command{ffmpeg} instances at startup.
-
-Input streams are called feeds, and each one is specified by a
-@code{<Feed>} section in the configuration file.
-
-For each feed you can have different output streams in various
-formats, each one specified by a @code{<Stream>} section in the
-configuration file.
-
-@chapter Detailed description
-
-@command{ffserver} works by forwarding streams encoded by
-@command{ffmpeg}, or pre-recorded streams which are read from disk.
-
-Precisely, @command{ffserver} acts as an HTTP server, accepting POST
-requests from @command{ffmpeg} to acquire the stream to publish, and
-serving RTSP clients or HTTP clients GET requests with the stream
-media content.
-
-A feed is an @ref{FFM} stream created by @command{ffmpeg}, and sent to
-a port where @command{ffserver} is listening.
-
-Each feed is identified by a unique name, corresponding to the name
-of the resource published on @command{ffserver}, and is configured by
-a dedicated @code{Feed} section in the configuration file.
-
-The feed publish URL is given by:
-@example
-http://@var{ffserver_ip_address}:@var{http_port}/@var{feed_name}
-@end example
-
-where @var{ffserver_ip_address} is the IP address of the machine where
-@command{ffserver} is installed, @var{http_port} is the port number of
-the HTTP server (configured through the @option{HTTPPort} option), and
-@var{feed_name} is the name of the corresponding feed defined in the
-configuration file.
-
-Each feed is associated to a file which is stored on disk. This stored
-file is used to send pre-recorded data to a player as fast as
-possible when new content is added in real-time to the stream.
-
-A "live-stream" or "stream" is a resource published by
-@command{ffserver}, and made accessible through the HTTP protocol to
-clients.
-
-A stream can be connected to a feed, or to a file. In the first case,
-the published stream is forwarded from the corresponding feed
-generated by a running instance of @command{ffmpeg}, in the second
-case the stream is read from a pre-recorded file.
-
-Each stream is identified by a unique name, corresponding to the name
-of the resource served by @command{ffserver}, and is configured by
-a dedicated @code{Stream} section in the configuration file.
-
-The stream access HTTP URL is given by:
-@example
-http://@var{ffserver_ip_address}:@var{http_port}/@var{stream_name}[@var{options}]
-@end example
-
-The stream access RTSP URL is given by:
-@example
-http://@var{ffserver_ip_address}:@var{rtsp_port}/@var{stream_name}[@var{options}]
-@end example
-
-@var{stream_name} is the name of the corresponding stream defined in
-the configuration file. @var{options} is a list of options specified
-after the URL which affects how the stream is served by
-@command{ffserver}. @var{http_port} and @var{rtsp_port} are the HTTP
-and RTSP ports configured with the options @var{HTTPPort} and
-@var{RTSPPort} respectively.
-
-In case the stream is associated to a feed, the encoding parameters
-must be configured in the stream configuration. They are sent to
-@command{ffmpeg} when setting up the encoding. This allows
-@command{ffserver} to define the encoding parameters used by
-the @command{ffmpeg} encoders.
-
-The @command{ffmpeg} @option{override_ffserver} commandline option
-allows one to override the encoding parameters set by the server.
-
-Multiple streams can be connected to the same feed.
-
-For example, you can have a situation described by the following
-graph:
-
-@verbatim
- _________ __________
- | | | |
-ffmpeg 1 -----| feed 1 |-----| stream 1 |
- \ |_________|\ |__________|
- \ \
- \ \ __________
- \ \ | |
- \ \| stream 2 |
- \ |__________|
- \
- \ _________ __________
- \ | | | |
- \| feed 2 |-----| stream 3 |
- |_________| |__________|
-
- _________ __________
- | | | |
-ffmpeg 2 -----| feed 3 |-----| stream 4 |
- |_________| |__________|
-
- _________ __________
- | | | |
- | file 1 |-----| stream 5 |
- |_________| |__________|
-
-@end verbatim
-
-@anchor{FFM}
-@section FFM, FFM2 formats
-
-FFM and FFM2 are formats used by ffserver. They allow storing a wide variety of
-video and audio streams and encoding options, and can store a moving time segment
-of an infinite movie or a whole movie.
-
-FFM is version specific, and there is limited compatibility of FFM files
-generated by one version of ffmpeg/ffserver and another version of
-ffmpeg/ffserver. It may work but it is not guaranteed to work.
-
-FFM2 is extensible while maintaining compatibility and should work between
-differing versions of tools. FFM2 is the default.
-
-@section Status stream
-
-@command{ffserver} supports an HTTP interface which exposes the
-current status of the server.
-
-Simply point your browser to the address of the special status stream
-specified in the configuration file.
-
-For example if you have:
-@example
-<Stream status.html>
-Format status
-
-# Only allow local people to get the status
-ACL allow localhost
-ACL allow 192.168.0.0 192.168.255.255
-</Stream>
-@end example
-
-then the server will post a page with the status information when
-the special stream @file{status.html} is requested.
-
-@section How do I make it work?
-
-As a simple test, just run the following two command lines where INPUTFILE
-is some file which you can decode with ffmpeg:
-
-@example
-ffserver -f doc/ffserver.conf &
-ffmpeg -i INPUTFILE http://localhost:8090/feed1.ffm
-@end example
-
-At this point you should be able to go to your Windows machine and fire up
-Windows Media Player (WMP). Go to Open URL and enter
-
-@example
- http://<linuxbox>:8090/test.asf
-@end example
-
-You should (after a short delay) see video and hear audio.
-
-WARNING: trying to stream test1.mpg doesn't work with WMP as it tries to
-transfer the entire file before starting to play.
-The same is true of AVI files.
-
-You should edit the @file{ffserver.conf} file to suit your needs (in
-terms of frame rates etc). Then install @command{ffserver} and
-@command{ffmpeg}, write a script to start them up, and off you go.
-
-@section What else can it do?
-
-You can replay video from .ffm files that was recorded earlier.
-However, there are a number of caveats, including the fact that the
-ffserver parameters must match the original parameters used to record the
-file. If they do not, then ffserver deletes the file before recording into it.
-(Now that I write this, it seems broken).
-
-You can fiddle with many of the codec choices and encoding parameters, and
-there are a bunch more parameters that you cannot control. Post a message
-to the mailing list if there are some 'must have' parameters. Look in
-ffserver.conf for a list of the currently available controls.
-
-It will automatically generate the ASX or RAM files that are often used
-in browsers. These files are actually redirections to the underlying ASF
-or RM file. The reason for this is that the browser often fetches the
-entire file before starting up the external viewer. The redirection files
-are very small and can be transferred quickly. [The stream itself is
-often 'infinite' and thus the browser tries to download it and never
-finishes.]
-
-@section Tips
-
-* When you connect to a live stream, most players (WMP, RA, etc) want to
-buffer a certain number of seconds of material so that they can display the
-signal continuously. However, ffserver (by default) starts sending data
-in realtime. This means that there is a pause of a few seconds while the
-buffering is being done by the player. The good news is that this can be
-cured by adding a '?buffer=5' to the end of the URL. This means that the
-stream should start 5 seconds in the past -- and so the first 5 seconds
-of the stream are sent as fast as the network will allow. It will then
-slow down to real time. This noticeably improves the startup experience.
-
-You can also add a 'Preroll 15' statement into the ffserver.conf that will
-add the 15 second prebuffering on all requests that do not otherwise
-specify a time. In addition, ffserver will skip frames until a key_frame
-is found. This further reduces the startup delay by not transferring data
-that will be discarded.
-
-@section Why does the ?buffer / Preroll stop working after a time?
-
-It turns out that (on my machine at least) the number of frames successfully
-grabbed is marginally less than the number that ought to be grabbed. This
-means that the timestamp in the encoded data stream gets behind realtime.
-This means that if you say 'Preroll 10', then when the stream gets 10
-or more seconds behind, there is no Preroll left.
-
-Fixing this requires a change in the internals of how timestamps are
-handled.
-
-@section Does the @code{?date=} stuff work.
-
-Yes (subject to the limitation outlined above). Also note that whenever you
-start ffserver, it deletes the ffm file (if any parameters have changed),
-thus wiping out what you had recorded before.
-
-The format of the @code{?date=xxxxxx} is fairly flexible. You should use one
-of the following formats (the 'T' is literal):
-
-@example
-* YYYY-MM-DDTHH:MM:SS (localtime)
-* YYYY-MM-DDTHH:MM:SSZ (UTC)
-@end example
-
-You can omit the YYYY-MM-DD, and then it refers to the current day. However
-note that @samp{?date=16:00:00} refers to 16:00 on the current day -- this
-may be in the future and so is unlikely to be useful.
-
-You use this by adding the ?date= to the end of the URL for the stream.
-For example: @samp{http://localhost:8080/test.asf?date=2002-07-26T23:05:00}.

-@chapter Options
-@c man begin OPTIONS
-
-@include fftools-common-opts.texi
-
-@section Main options
-
-@table @option
-@item -f @var{configfile}
-Read configuration file @file{configfile}. If not specified it will
-read by default from @file{/etc/ffserver.conf}.
-
-@item -n
-Enable no-launch mode. This option disables all the @code{Launch}
-directives within the various @code{<Feed>} sections. Since
-@command{ffserver} will not launch any @command{ffmpeg} instances, you
-will have to launch them manually.
-
-@item -d
-Enable debug mode. This option increases log verbosity, and directs
-log messages to stdout. When specified, the @option{CustomLog} option
-is ignored.
-@end table
-
-@chapter Configuration file syntax
-
-@command{ffserver} reads a configuration file containing global
-options and settings for each stream and feed.
-
-The configuration file consists of global options and dedicated
-sections, which must be introduced by "<@var{SECTION_NAME}
-@var{ARGS}>" on a separate line and must be terminated by a line in
-the form "</@var{SECTION_NAME}>". @var{ARGS} is optional.
-
-Currently the following sections are recognized: @samp{Feed},
-@samp{Stream}, @samp{Redirect}.
-
-A line starting with @code{#} is ignored and treated as a comment.
-
-Name of options and sections are case-insensitive.
-
-@section ACL syntax
-An ACL (Access Control List) specifies the address which are allowed
-to access a given stream, or to write a given feed.
-
-It accepts the folling forms
-@itemize
-@item
-Allow/deny access to @var{address}.
-@example
-ACL ALLOW <address>
-ACL DENY <address>
-@end example
-
-@item
-Allow/deny access to ranges of addresses from @var{first_address} to
-@var{last_address}.
-@example
-ACL ALLOW <first_address> <last_address>
-ACL DENY <first_address> <last_address>
-@end example
-@end itemize
-
-You can repeat the ACL allow/deny as often as you like. It is on a per
-stream basis. The first match defines the action. If there are no matches,
-then the default is the inverse of the last ACL statement.
-
-Thus 'ACL allow localhost' only allows access from localhost.
-'ACL deny 1.0.0.0 1.255.255.255' would deny the whole of network 1 and
-allow everybody else.
-
-@section Global options
-@table @option
-@item HTTPPort @var{port_number}
-@item Port @var{port_number}
-@item RTSPPort @var{port_number}
-
-@var{HTTPPort} sets the HTTP server listening TCP port number,
-@var{RTSPPort} sets the RTSP server listening TCP port number.
-
-@var{Port} is the equivalent of @var{HTTPPort} and is deprecated.
-
-You must select a different port from your standard HTTP web server if
-it is running on the same computer.
-
-If not specified, no corresponding server will be created.
-
-@item HTTPBindAddress @var{ip_address}
-@item BindAddress @var{ip_address}
-@item RTSPBindAddress @var{ip_address}
-Set address on which the HTTP/RTSP server is bound. Only useful if you
-have several network interfaces.
-
-@var{BindAddress} is the equivalent of @var{HTTPBindAddress} and is
-deprecated.
-
-@item MaxHTTPConnections @var{n}
-Set number of simultaneous HTTP connections that can be handled. It
-has to be defined @emph{before} the @option{MaxClients} parameter,
-since it defines the @option{MaxClients} maximum limit.
-
-Default value is 2000.
-
-@item MaxClients @var{n}
-Set number of simultaneous requests that can be handled. Since
-@command{ffserver} is very fast, it is more likely that you will want
-to leave this high and use @option{MaxBandwidth}.
-
-Default value is 5.
-
-@item MaxBandwidth @var{kbps}
-Set the maximum amount of kbit/sec that you are prepared to consume
-when streaming to clients.
-
-Default value is 1000.
-
-@item CustomLog @var{filename}
-Set access log file (uses standard Apache log file format). '-' is the
-standard output.
-
-If not specified @command{ffserver} will produce no log.
-
-In case the commandline option @option{-d} is specified this option is
-ignored, and the log is written to standard output.
-
-@item NoDaemon
-Set no-daemon mode. This option is currently ignored since now
-@command{ffserver} will always work in no-daemon mode, and is
-deprecated.
-
-@item UseDefaults
-@item NoDefaults
-Control whether default codec options are used for the all streams or not.
-Each stream may overwrite this setting for its own. Default is @var{UseDefaults}.
-The lastest occurrence overrides previous if multiple definitions.
-@end table
-
-@section Feed section
-
-A Feed section defines a feed provided to @command{ffserver}.
-
-Each live feed contains one video and/or audio sequence coming from an
-@command{ffmpeg} encoder or another @command{ffserver}. This sequence
-may be encoded simultaneously with several codecs at several
-resolutions.
-
-A feed instance specification is introduced by a line in the form:
-@example
-<Feed FEED_FILENAME>
-@end example
-
-where @var{FEED_FILENAME} specifies the unique name of the FFM stream.
-
-The following options are recognized within a Feed section.
-
-@table @option
-@item File @var{filename}
-@item ReadOnlyFile @var{filename}
-Set the path where the feed file is stored on disk.
-
-If not specified, the @file{/tmp/FEED.ffm} is assumed, where
-@var{FEED} is the feed name.
-
-If @option{ReadOnlyFile} is used the file is marked as read-only and
-it will not be deleted or updated.
-
-@item Truncate
-Truncate the feed file, rather than appending to it. By default
-@command{ffserver} will append data to the file, until the maximum
-file size value is reached (see @option{FileMaxSize} option).
-
-@item FileMaxSize @var{size}
-Set maximum size of the feed file in bytes. 0 means unlimited. The
-postfixes @code{K} (2^10), @code{M} (2^20), and @code{G} (2^30) are
-recognized.
-
-Default value is 5M.
-
-@item Launch @var{args}
-Launch an @command{ffmpeg} command when creating @command{ffserver}.
-
-@var{args} must be a sequence of arguments to be provided to an
-@command{ffmpeg} instance. The first provided argument is ignored, and
-it is replaced by a path with the same dirname of the @command{ffserver}
-instance, followed by the remaining argument and terminated with a
-path corresponding to the feed.
-
-When the launched process exits, @command{ffserver} will launch
-another program instance.
-
-In case you need a more complex @command{ffmpeg} configuration,
-e.g. if you need to generate multiple FFM feeds with a single
-@command{ffmpeg} instance, you should launch @command{ffmpeg} by hand.
-
-This option is ignored in case the commandline option @option{-n} is
-specified.
-
-@item ACL @var{spec}
-Specify the list of IP address which are allowed or denied to write
-the feed. Multiple ACL options can be specified.
-@end table
-
-@section Stream section
-
-A Stream section defines a stream provided by @command{ffserver}, and
-identified by a single name.
-
-The stream is sent when answering a request containing the stream
-name.
-
-A stream section must be introduced by the line:
-@example
-<Stream STREAM_NAME>
-@end example
-
-where @var{STREAM_NAME} specifies the unique name of the stream.
-
-The following options are recognized within a Stream section.
-
-Encoding options are marked with the @emph{encoding} tag, and they are
-used to set the encoding parameters, and are mapped to libavcodec
-encoding options. Not all encoding options are supported, in
-particular it is not possible to set encoder private options. In order
-to override the encoding options specified by @command{ffserver}, you
-can use the @command{ffmpeg} @option{override_ffserver} commandline
-option.
-
-Only one of the @option{Feed} and @option{File} options should be set.
-
-@table @option
-@item Feed @var{feed_name}
-Set the input feed. @var{feed_name} must correspond to an existing
-feed defined in a @code{Feed} section.
-
-When this option is set, encoding options are used to setup the
-encoding operated by the remote @command{ffmpeg} process.
-
-@item File @var{filename}
-Set the filename of the pre-recorded input file to stream.
-
-When this option is set, encoding options are ignored and the input
-file content is re-streamed as is.
-
-@item Format @var{format_name}
-Set the format of the output stream.
-
-Must be the name of a format recognized by FFmpeg. If set to
-@samp{status}, it is treated as a status stream.
-
-@item InputFormat @var{format_name}
-Set input format. If not specified, it is automatically guessed.
-
-@item Preroll @var{n}
-Set this to the number of seconds backwards in time to start. Note that
-most players will buffer 5-10 seconds of video, and also you need to allow
-for a keyframe to appear in the data stream.
-
-Default value is 0.
-
-@item StartSendOnKey
-Do not send stream until it gets the first key frame. By default
-@command{ffserver} will send data immediately.
-
-@item MaxTime @var{n}
-Set the number of seconds to run. This value set the maximum duration
-of the stream a client will be able to receive.
-
-A value of 0 means that no limit is set on the stream duration.
-
-@item ACL @var{spec}
-Set ACL for the stream.
-
-@item DynamicACL @var{spec}

-deprecated in favor of @option{Metadata}.
-
-@item Metadata @var{key} @var{value}
-Set metadata value on the output stream.
-
-@item UseDefaults
-@item NoDefaults
-Control whether default codec options are used for the stream or not.

-
-@item AudioChannels @var{n} (@emph{encoding,audio})
-Set number of audio channels.
-
-@item AudioSampleRate @var{n} (@emph{encoding,audio})
-Set sampling frequency for audio. When using low bitrates, you should
-lower this frequency to 22050 or 11025. The supported frequencies
-depend on the selected audio codec.
-
-@item AVOptionAudio [@var{codec}:]@var{option} @var{value} (@emph{encoding,audio})

-statistics about the @command{ffserver} operations.
-
-It must be specified setting the option @option{Format} to
-@samp{status}.
-
-@section Redirect section
-
-A redirect section specifies where to redirect the requested URL to
