-/**
- * Following API allows user to probe device capabilities (supported codecs,
- * pixel formats, sample formats, resolutions, channel counts, etc).
- * It is build on top op AVOption API.
- * Queried capabilities make it possible to set up converters of video or audio
- * parameters that fit to the device.
- *
- * List of capabilities that can be queried:
- * - Capabilities valid for both audio and video devices:
- * - codec: supported audio/video codecs.
- * type: AV_OPT_TYPE_INT (AVCodecID value)
- * - Capabilities valid for audio devices:
- * - sample_format: supported sample formats.
- * type: AV_OPT_TYPE_INT (AVSampleFormat value)
- * - sample_rate: supported sample rates.
- * type: AV_OPT_TYPE_INT
- * - channels: supported number of channels.
- * type: AV_OPT_TYPE_INT
- * - channel_layout: supported channel layouts.
- * type: AV_OPT_TYPE_INT64
- * - Capabilities valid for video devices:
- * - pixel_format: supported pixel formats.
- * type: AV_OPT_TYPE_INT (AVPixelFormat value)
- * - window_size: supported window sizes (describes size of the window size presented to the user).
- * type: AV_OPT_TYPE_IMAGE_SIZE
- * - frame_size: supported frame sizes (describes size of provided video frames).
- * type: AV_OPT_TYPE_IMAGE_SIZE
- * - fps: supported fps values
- * type: AV_OPT_TYPE_RATIONAL
- *
- * Value of the capability may be set by user using av_opt_set() function
- * and AVDeviceCapabilitiesQuery object. Following queries will
- * limit results to the values matching already set capabilities.
- * For example, setting a codec may impact number of formats or fps values
- * returned during next query. Setting invalid value may limit results to zero.
- *
- * Example of the usage basing on opengl output device:
- *
- * @code
- * AVFormatContext *oc = NULL;
- * AVDeviceCapabilitiesQuery *caps = NULL;
- * AVOptionRanges *ranges;
- * int ret;
- *
- * if ((ret = avformat_alloc_output_context2(&oc, NULL, "opengl", NULL)) < 0)
- * goto fail;
- * if (avdevice_capabilities_create(&caps, oc, NULL) < 0)
- * goto fail;
- *
- * //query codecs
- * if (av_opt_query_ranges(&ranges, caps, "codec", AV_OPT_MULTI_COMPONENT_RANGE)) < 0)
- * goto fail;
- * //pick codec here and set it
- * av_opt_set(caps, "codec", AV_CODEC_ID_RAWVIDEO, 0);
- *
- * //query format
- * if (av_opt_query_ranges(&ranges, caps, "pixel_format", AV_OPT_MULTI_COMPONENT_RANGE)) < 0)
- * goto fail;
- * //pick format here and set it
- * av_opt_set(caps, "pixel_format", AV_PIX_FMT_YUV420P, 0);
- *
- * //query and set more capabilities
- *
- * fail:
- * //clean up code
- * avdevice_capabilities_free(&query, oc);
- * avformat_free_context(oc);
