Hi, I do not know who is the right guy to ask, so I send this to the list. I have a so called "Referenz DVD" with lots of still pictures with bars and stripes to setup your equipment correctly. These are coded as normal vob files, but nothing is displayed when I try to view them with xine. Only the audio is fine. I understand that the mpeg2dec does not support all kind of mpeg2 features. Are there any plans to develop the missing stuff ? I could provide sample vob files if needed. mfg Joachim |

Can you try with mpeg2dec CVS from http://www.linuxvideo.org/mpeg2dec/ ? That one should handle all main profile bitstreams. If you have one vob file that doesnt work with it I'd like to hear about it. As for xine itself, I havent looked in enough detail lately, but I'm not sure if it got the latest changes in mpeg2dec for handling field pictures. Hope this helps, -- Michel "Walken" LESPINASSE Of course I think I'm right. If I thought I was wrong, I'd change my mind. |

I think there needs to be an libmpeg2 update been done. Guenter are you listening...........:) mfg Joachim |

I've updated libmpeg before the xine 0.3.5 release so libmpeg2 is up-to-date (except for slice.c and decode.c ... but I think I've got everything that's needed for field picture support). The problem seems to be the interface between libmpeg2 and the video_out routines =2E.. somehow the detection when a frame is finished decoding fails in this case. I didn't have time to look into this yet, but I've got that "referenz DVD" from german "video das testmagazin" so I got plenty of test streams and I know that nearly all of the stuff on that dvd doesn't work. Michel, do these problems (failing frame end detection) ring any bell? Is there something special with field pictures that I have to take care of? Anyway, please be patient, I hope to fix this soon. Regards, Guenter |

I was happy about it too, because the new organisation was simpler anyway :) look how its done in mpeg2dec, we handle the "new picture" case when we see the first slice after anything else than a slice, and we handle the "end of picture" case when we see anything else than a slice and the previous chunk was a slice. In these code paths you have to check if you're decoding the first field or the second field of a picture. But, I think you updated xine already :) Hope this helps, -- Michel "Walken" LESPINASSE Of course I think I'm right. If I thought I was wrong, I'd change my mind. |
