[Ffmpeg-devel] [PATCH] set interlaced_frame and top_field_first in yuv4mpeg

[Luca Abeni]

Hi all,

now that libavcodec/raw.c permits to set the interlaced_frame and
top_field_first fields, formats using it can take advantage of such
feature.

As promised, here is a patch for libavformat/yuv4mpeg.c to correctly (I
hope :) set the two fields.

I quickly tested it, and works ok in my testcase (I captured a .y4m file
from a tv card with
./ffmpeg -y -vd /dev/video0 -ad /dev/dsp0 -pix_fmt yuv420p -s 352x288 test.y4m
and then read it with libavcodec, checking interlaced_frame and
top_field_first in the frames that I was reading from the file).

				Luca
