needs to be changed accordingly). It "works" but I can't spot any
difference between postproc-q 6 and postproc-q 0 using the
redefined-nintendo.mpg test video ... I'd appreciate feedback on that
point.

Better comment them fully, if you are too lazy to report upstream

Use tabs in Makefile

Some more seperation of the different ffmpeg based modules. They're now completely disjoint except for the common chroma.h and fourcc.h headers.

Img resample based module (functionality untested ... but compilation and loading works). Remove unneeded stuff from swscale.

Add fallback to img_resample based plugin if swscale isn't available on the system. img_resample will be built as a seperate module than avcodec to prevent avcodec from refusing to dlopen if img_resample is unavailable (debian...).

Split ffmpeg module in avcodec (decoders, encoders, deinterlacing), avformat (demuxers, muxers), swscale (scaling, chroma conversion) and postproc modules.

With the mutex patch plus a few fixes.

While reading this, you will find a bunch of:
  while (find (VLC_OBJECT_INTERFACE))
     release; release;

These are of course plain BUGS (which are neither introduced nor fixed
by this commit). Imagine, for instance, what happens if two threads run
the code above at the same time... they end up releasing the interface
once too many.

Fix the rawvideo codec when visible_pitch != pitch. (And simplify code) This should fix partial screen captures using non multiple of 16 values.
