Bug#797965: bs1770gain somehow "destroys" gapless playback on (at least) lame encoded MP3s

[Christoph Anton Mitterer]

Hey.

Andreas, anything new on this? What happened to your proposed patch?

Carl:
- The command lines are given in the initial mail of this bug.
- IIRC a sample link was provided somewhere as well, but if that
  doesn't suit you, simply take *any* wav file on earth, split it in
  two halfs a a position with sound, encode the resulting files with
  e.g. lame, process it with bs1770gain (and thus ffmpeg) and then
  you'll see how the gapless information gets destroyed.
- As for logs, this is always a bit tedious,... I did provide such logs
  in other bugs I've opened at ffmpeg upstream about gapless playback
  issues, with never any clear outcome.
  Since ffmpeg has quite some development pace, any such logs would be
  useless few weeks after I've posted them.
  If a developer actually looks into that issue, I can of course
  provide such logs, but since this is a general bug, it's really very
  easy to create sample files and logs oneself. I'd say it doesn't take
  5 mins, and for an audio developer probably even less.


Cheers,
Chris.
