Encoding H.264 in AVI with libquicktime should work now (do cvs update
for libquicktime).

That hang is fixed (cvs update in gmerlin_encoders)

Wow, that was a good catch: A timestamp issue occurring only when
frame_duration > 1 (like in your NTSC test stream).

I normally use PAL here, which is 25/1, so for me everything worked.

Should be fixed as well. Actually the hang was the player waiting to
show a frame in a distant (33.4 sec) future.

Should be fixed.

Same as above, should be fixed. After fixing the encoding hang I discovered
and fixed another bug when encoding 16pcm.

Should work as well now.

I also tried 2 more important formats: ASF and FLV. They are more important
because for AVI one can use libquicktime as well. Both ASF and FLV encoding
is broken atm probably due to some ffmpeg change (because they both worked
earlier). I'll look into this tomorrow.
