success! (well sort of)


I applied the patch above to mplayer and can now watch ITV HD, however
the video is jerky and I get lots of PAFF errors:

looks like this is using the mpegts demuxer. I have tried to use the
coreavc patch as well but the lavf demuxer required for the coreavc
decoder doesn't like the ITV container. Trying to force
coreavc-for-linux to use the mpegts demuxer results in an error.

Does anyone know if there is a patch so I can use the mpegts demuxer
with coreavc so I can test if it handles the video better, or if I can
select the video id for the lavf demuxer

This patch: http://lists.mplayerhq.hu/pipermail/mplayer-dev-eng/2006-October/046462.html
doesn't seem to work with the latest SVN; I will try to manually alter
it to fit.
