avidemux vs qtdemux

[Angel Martin]

Hi,

if you want to profile your application I suggest "top" for a quick evaluation.
If you feel like boosting something and change some parts of gstreamer
libraries-code I'd suggest to start with "valgrind".

I do not fully understand what do you mean with faster, because the
video has a framerate and must be played at this rate.

Anyway, it is supposed that the bigger amount of computing in terms of
CPU cycles and memory usage lays on the encoding/decoding tasks, so if
you just change the encapsulator the impact should be residual.

Best,

Angel
