Hi, I am letting myself known incase someone is interested in this or already has ideas on the subject. I would like to add Theora encoding to ffmpeg's libavcodec library. My goal is to add vorbis / theora / ogm output to Handbrake. Doing this at the libavcodec level appears to make the most sense as it would benefit more people. I have already made a small start. I have the configure & build scripts for ffmpeg using the correct libraries etc. I am n...

Hi, Attached is my patch to add theora encoding to ffmpeg's libavcodec (by using libtheora). I am requesting help to fix the bug I mention below and am seeking general comments before I submit the patch properly. Files encoded using this encoder have a problem playing in VLC. The files will not play unless "Drop late frames" has been unticked in the advan...

As you say, a lot of applications use ffmpeg/libavcodec instead. A much easier solution, which works with ffmpeg right out of the box, even with older distributions (such as Ubuntu 22.04 you mention) is to use the wavpack codec instead of flac. It supports samplerates up to 1 GHz, has an arguably better way of seeking, supports a 40 bit number for samp...

...to use the FFmpeg library to decode WMA audio. This means for most games, Wine's built-in xaudio2 will require that the 32-bit FFmpeg library be available on the system to successfully play audio. The new code only uses the audio decoding features of FFmpeg, specifically linking only against libavcodec and libavutil. The newest APIs that we use were introduced in 2013. Most of the rest date from 2011 and a few from 2002. FFmpeg's API isn't stable, but I don't expect much maintenance burden from the small piece that we're using. An additional complication is the libav fork. The AP...

...ultiple channels copied from the same stream" feature isn't available. I don't particularly expect this to be an issue, but if people have problems with it, we can instead keep the existing table and add a simple bitmask before or after it. I've looked into the relevant changes in libavcodec and libopus. It's reasonably simple to add on the decode side in libavcodec's native decoder (largely changes to ff_opus_parse_extradata), but it's a bit trickier in libopus, because there's no support in the API for channel layouts (and thus stereo stream counts) other than those i...

https://roundup.ffmpeg.org/roundup/ffmpeg/issue1197 I had originally encountered this problem using ffmpeg2theora. I switched to ffmpeg proper in an attempt to identify where the problem was at, and found that the problem persisted. As a result I had thought this was a problem with ffmpeg, but the ffmpeg folks seem to indicate that this is specific to Theora (too much finger pointing I think.) I
