Could you provide a sample file to reproduce this?

 Unfortunately, I am unable to do this due to BBC's copyright. However,
any file (TV program) downloaded from the BBC's iPlayer website
will cause Avidemux to abend on attempting to import. Perhaps you
can find a way to download you own. I have used get_iplayer.

I got the same here with flv files from ARD, ZDF and NDR.

I would be able to provide a sample file, but with 580 MB its quite big. So I would like to know if this would still be useful.

The same problem with flv videos downloaded from SVT. Avidemux 2.5.2 (1:2.5.2-0ubuntu3)

After remux with mencoder, avidemux can read the file for editing or transcoding. Tested with two videos from SVT and with pjw's 10 sec sample.

mencoder -mc 0 -oac copy -ovc copy -of lavf infile.flv -o outfile.flv

(The flv files from SVT have B-frames so avidemux must use safe mode which affects seek precision. The 10 sec sample does not have B-frames and don't need safe mode. A/V is out of sync in avidemux, but not in totem and mplayer.)

(continuing comment #7, workarounds)

Alternatively remux with ffmpeg, with about the same result.

ffmpeg -i infile.flv -vcodec copy -acodec copy outfile.flv
