This fixes: https://trac.ffmpeg.org/ticket/9502 API ref: https://developer.apple.com/documentation/audiotoolbox/audio_converter_services Signed-off-by: Romain Beauxis <to...@rastageeks.org> — [Sorry for the noise but an issue came up with the previous set] This is the first patch of a series of 3 that fix, cleanup and enhance the avfoundation implementation for libavdevice. These patches come from an actual user-facing application relying on libavdevice’s implementation of avfoundation audio input. Without them, Avfoundation is practically unusable as it will: * Refuse to process certain specific audio input format that are actually returned by the OS for some users (packed PCM audio) * Drop audio frames, resulting in corrupted audio input. This might have been unnoticed with video frames but this makes avfoundation essentially unusable for audio. The patches are now being included in our production build so they are tested and usable in production. Changelog for this patch: * v2: None * v3: None * v4: None * v5: Fix indentation/wrapping * v6: None * v7: Removed use of kAudioConverterPropertyCalculateOutputBufferSize to calculate output buffer size. The calculation is trivial and this call was randomly failing for no reason * v8: None
Why new versions if no changes? Regards, Gyan _______________________________________________ ffmpeg-devel mailing list ffmpeg-devel@ffmpeg.org https://ffmpeg.org/mailman/listinfo/ffmpeg-devel To unsubscribe, visit link above, or email ffmpeg-devel-requ...@ffmpeg.org with subject "unsubscribe".
