[FFmpeg-devel] [PATCH] Lost VBR header

[Peter Belkner]

Hi,

FFmpeg is known for eating up the VBR header of MP3 files in case of 
stream copy as e.g.

    ffmpeg -i a.mp3 -acodec copy -y b.mp3

The patch fixes this provided the "-acodec" switch is given in front of 
the "-i" switch:

    ffmpeg -acode copy -i a.mp3 -y b.mp3

Apart from this subtility the patch should improve "libavformat.a" in 
order that third party client code may copy MP3s without losing the VBR 
header (as. e.g. my R128GAIN, see below).

I really would apreciate if you could apply the patch or provide an 
equivalent solution.

Thank you for your ongoing effort.

Peter
