<ffmpeg-devel@ffmpeg.org<mailto:ffmpeg-devel@ffmpeg.org>> Date 1/7/2024 12:44:03 AM Subject Re: [FFmpeg-devel] [PATCH 4/4] avformat/psxstr: basic FPS detection instead of fixed value On Tue, Jan 02, 2024 at 03:14:19AM +0000, aybe aybe wrote: This fourth and last patch is an attempt at removing the hard-coded value of 15 FPS. In patch 1/4, although it would render video, the audio and video were not synchronized at all, now there are. In this approach I kept it simple, grab min/max possible rates, pick min, clamp to 15/30 just in case. It appears to work quite well, the right frame rate is picked up and both streams are in sync. (tested against Wipeout introduction for both PAL and NTSC versions). Besides, there have been significant findings over the years regarding that format, specifically: https://problemkaputt.de/psxspx-macroblock-decoder-mdec.htm https://github.com/m35/jpsxdec/blob/readme/jpsxdec/PlayStation1_STR_format.txt Maybe someone versed in this topic (I'm not) could further improve support of this format according these docs...

Sorry mate but I'm currently having a lot of trouble keeping in track with the mailing list...
I thought emClient would be a savior but it isn't, it's buggy and confusing as hell.
Have to check mailing list online, find mail in client so I can reply to it, really boring!
Anyway... for the patch I simply followed what the previous author did
Previous author did put 15 there and when played in VLC you get 15 FPS.
Therefore, I concluded that it is indeed the right place where this should be updated.
Format itself does not store the FPS, people would know in advance movie size/speed.
But as mentioned before, it is sort of possible to 'detect' that, what I've done in the patch.
A good source of information about the format is the following link:
https://github.com/m35/jpsxdec/blob/readme/jpsxdec/PlayStation1_STR_format.txt
My approach differs with the above in the sense that I assume min FPS is definitely right.
And that works on the movies I have tested so far, it returns 25/30 for PAL/NTSC versions.

This fourth and last patch is an attempt at removing the hard-coded value of 15 FPS.
In patch 1/4, although it would render video, the audio and video were not synchronized at all, now there are.
In this approach I kept it simple, grab min/max possible rates, pick min, clamp to 15/30 just in case.
It appears to work quite well, the right frame rate is picked up and both streams are in sync.
(tested against Wipeout introduction for both PAL and NTSC versions).
Besides, there have been significant findings over the years regarding that format, specifically:
https://problemkaputt.de/psxspx-macroblock-decoder-mdec.htm

Maybe someone versed in this topic (I'm not) could further improve support of this format according these docs...
