[Ffmpeg-devel] [PATCH] video4linux2 input

Hi all,

I think my video4linux2 input format is ready for inclusion. It still
has some unimplemented features (for example, read() and user-pointer
based input still have to be implemented, and QBUF/DQBUF failures are
currently not handled) but it works fairly well (for me, it works better
than the current video4linux input), and I think missing features can be
added later.

So, attached are the new v4l2.c file and a patch for ffmpeg CVS (I hope
I got the configure part right... ;-).

Changes from the previous version of v4l2.c:
- removed the crop stuff
- introduced code to correctly (I hope ;-) set interlaced_frame and top_field_first
- changed some constants from "#define" to "enum"
- changed the code to use as many video buffers as possible
- some cleanups

If there are problems in the code preventing its inclusion in ffmpeg
CVS, let me know and I'll do my best to fix them.

Copy this in your signature, if you think it is important:
