[FFmpeg-devel] Sound desynchronisation, resampling and duration

Dear all,

I use Kdenlive 0.6 svn video editor, based on MLT and ffmpeg. The result
is great and will probably compare to professional solutions. 

I can only complain from :

* Frequent sound desynchronisation. Sometimes 0.1 or 0.2 seconds, but it
can be seen and heard. 
* Poor sound resampling. Especially when playing low sample rates (8.000
hz) at higher bitrates (48.000 hz).
* Sometimes the duration of a video is not correct and does not
correspond to the duration of stream.

I guess this is a know problem and I hope that these issues can be
adressed in a short term future. 

In video editing, accuracy is very important, as for duration,
synchronisation and resampling. Continue the good work. 

Kind regards,
