[FFmpeg-devel] [PATCH] Implement pixdesc.h:write_line()

[Stefano Sabatini]

Hi all.

Formats when possible have been tested with the vf_pixdesc_test
filter, included the monowhite and monoblack formats, with something
like:

ffplay in.avi -vfilters "format=gray,pixdesc_test"

Some formats cannot be tested this way, for example all the formats
not supported as output by sws, anyway I think that it's quite safe to
apply it anyway.

Many interesting problems remains opened, for example:

* How are we supposed to deal with HW accelerated pixel formats?  Are
  we supposed to add an entry in the pixdescs arrays for each of them?

* It's not clear which should be the interaction between lsws and
  the pixdescs.

  Currently lsws doesn't depend on lavc, since the pixfmt descriptors
  may and should be used in libsws to avoid code duplication
  (e.g. sws_format_name()), we may either add lavc to the lsws
  dependancies *or* move all the pixdesc stuff to lavu.

Regards.
