Hi,

Well, the spec tells you that aspect_ratio_idc 11 means a sample (pixel) aspect ratio 15:11 (1.3636). And you have 1440 x 1080 pixels so the frame aspect ratio yields:
far = 1.3636 * 1440 / 1080 = 1.8181Could you give me a link to where you found that please?
I've posted the URL to the spec some weeks ago already. In that issue, have a look into Annex E.2.1, Table E-1, Page 313.
Also, I just discovered another problem with this method. I was wondering why the performance on HD was so poor and it turns out that the picture was being de-interlaced twice, once by CoreAVC for the h264 picture and then by xine post plugin (tvtime). When I remove the post deinterlacing plugin the performance is much better and now seems to decode all the h264 channels I have access to pretty well with ~40% idle. However, when I go back to a MPEG2 channel of course the deinterlacing is now disabled and it looks terrible!
Do you know if its possible to enable de-interlacing for only a certain picture type(s), or am I looking at this the wrong way?
Simply set the progressive_frame flag.
But use_progressive_frame_flag=0 overrides this information and will still deinterlace.
To disable it completely for your decoder even in this case, do not set VO_INTERLACED_FLAG when getting the frame.
Have a look into ff_video_decoder.c.
Bye.
