Hi

After boosting the audio volume in video clip the audio in resulting mp4 file
is stuttering
at the beginning of a clip. The stuttering occurs only at the beginning
of a file and lasts no more than a second. I use avidemux 2.5.6-r2 on Linux
Gentoo.

When loading the source file that is later going to be volume boosted I receive
the following message:

H.264 detected
If the file is using B-frames as reference it can lead to a crash or stuttering.
Avidemux can use another mode which is safe but YOU WILL LOSE FRAME ACCURACY.
Do you want to use that mode?

Doesn't matter which mode I use I always get the same stuttering volume boosted
result.

Both source and volume boosted (stuttering) files are mp4 files
(AAC(faac)/H.264).
I've uploaded the source.mp4 file here:

and stuttering.mp4 file here:

Files are small and take about 1.5 MB each. Please click "Pobierz" to download
the files (in case you fall into Polish version of a site:))

Please help me to solve this issue.

Should try with avidemux 2.6.3 preferred if available for gento, if not with 2.6.2, 2.6.1 or 2.6.0. If someone provides/builds these?

I've finally tested it with avidemux 2.6.4 on Gentoo with AAC(lav) audio codec and it works great.
Thanks.
Problem solved.
