only mpeg1/2 supported for rtp and udp output because of low delay forcing in ffmpeg

Using anything but mpeg1/2 and RTP or UDP output will fail using recent FFmpeg (might affect more combinations). This was tested against 20061123-1759. This is a major regression. A fairly recent version from 20061102 still works ok.

ffmpeg warning: low delay forcing is only available for mpeg1/2
(mpeg4@03B4CEB0)
ffmpeg error: cannot open encoder
main warning: no encoder module matching "ffmpeg" could be loaded

FFmpeg revision 7008 (commit date 20061113) adds this check:http://svn.mplayerhq.hu/ffmpeg/trunk/libavcodec/mpegvideo.c?r1=6995&r2=7008&pathrev=7008

changed title from only mpeg1/2 supported for rtp output because of low delay forcing in ffmpeg to only mpeg1/2 supported for rtp and udp output because of low delay forcing in ffmpeg

changed the description

from bcoudurier @ #ffmpeg: low_delay forcing when encoding is to force dts == pts. basically for mpeg4, it only depended on max_b_frames. for mpeg1/2 it's different since vcd/svcd might require low_delay to be 0 even if stream contains no b frames
