[FFmpeg-devel] [PATCH 0/3] Fix gapless encoding/decoding for MP3

[Jon Toohill]

Round trip wav->mp3->wav now preserves the correct number of samples.
Remuxing mp3->mp3 with -c:a copy also preserves any existing gapless
metadata in the Info tag.

The code in libmp3lame.c to set AV_PKT_DATA_SKIP_SAMPLES was mostly
copied from libopusenc.c.

Jon Toohill (3):
  lavc/libmp3lame: send encoder padding in side data of final packet
  lavf/mp3enc: write encoder delay/padding upon closing
  lavf/mp3dec: read encoder delay/padding from Info tag
