^ FOLLOW-UP:
one thing I have not understood yet...
¿why neither xvid_encraw nor x264 include an MP4 multiplexer in their respective source-codes?
I mean:
x264 by default is compiled with an FLV muxer and an MKV muxer, but if one wants an MP4 output, then they must first compile and install L-Smash or (blargh!)GPAC;
and
xvid_encraw doesn't even have such lazy option(s);;
then my question is:
¿is it that difficult to write a .C or .CPP file + a .H file dedicated to multiplex only ASP or AVC elementary streams to an MP4 container?
