Hello,
I'm trying to encode to FLAC via avcodec/avformat. Unfortunately this
gives invalid FLACs. I'm following "doc/examples/transcoding.c" which,
of course, makes the problem reproducible.
If I transcode a valid FLAC to FLAC with the example program "transcode"
I get a FLAC which is not valid according to the FLAC reference encoder:
> $ flac -t ./test/output/Track101.flac
>
> flac 1.2.1, Copyright (C) 2000,2001,2002,2003,2004,2005,2006,2007

Such a FLAC can't be played with a typical FLAC decoder, but with FFmpeg.
On the other hand, the command line "ffmpeg" program produces valid FLACs.
What's the difference between "ffmpeg" and "transcode"? What's missing
in "transcode"?
