FFmpeg introduced a new channel layout API that uses `AVChannelLayout` interface in v6.0. It subsequently dropped the old bitmask-based API in v7.0. This updates decode_audio() to support the new channel layout API, so that we can compile `whisper-cli` and `whisper-server` with FFmpeg v7.0 or later. Tested on on Ubuntu 24.10 with FFmpeg v7.0.2.

Note: I can confirm that this patch enables us to build $ # Compile test on Ubuntu 24.10 with FFmpeg v7.0.2
$ git checkout sf/ffmpeg-v7
$ cmake -B build -D WHISPER_FFMPEG=yes
$ cmake --build build
$ # Confirm that it works fine with FFmpeg v7
$ ./build/bin/whisper-cli -np -m models/ggml-tiny.bin jfk.opus
[00:00:00.000 --> 00:00:10.560] And so, my fellow Americans, ask not what your country can do for you, ask what you can do for your country.The API change I mentioned above was introduced by the following commits
I believe this changeset has already landed on Fedora 41 and Ubuntu 24.10. |
