Together with the previous commit, this seems to make backward playback work in files with vorbis and mp3 audio codecs. For Vorbis (with libavcodec's decoder, didn't test libvorbis), the first packet was just always completely discarded. This happened even though we tell libavcodec that we do discarding of padding manually. It simply happened inside the codec, not libavcodec's general initial padding handling. In addition, the first output decoded frame seems to contain partial data. (Unlike the opus decoder, it doesn't report any padding at all.) The Opus decoder (again libavcodec only tested) reports an initial padding, but it appears to be too small, and it sounds right only with 2 packets discarded. So its status doesn't change. I'm not sure why I need 2 frames for mp3, but with that value I had success on the samples I tested. |
