Packed Bitsream of B-frame...
Is it still not working?
I've tried to encode a clip with bframe and PB on, it seems there is no problem. (kinda sick of that black screen whenever playback of file with bf) What's the problem with it? e.g. not compatible with Divx5 or the stream it produce is not MPEG-4 compliant? Just being curious, since the last update on it was like half a year ago |

B-frames are still buggy(depends alot here on source),I noticed in IAGO's guide it says NOT to select it(if memory serves).
Cheers!!!

- max and min i-frame interval don't work - when lumimasiking is used, they sometimes have strange quantizers - well yes, packed bitstream doesn't work - anyone needs it? ...and that's it. If you are refering to something which isn't here _please_ tell me. I'm far from knowing everything Radek |

It's important to me to know if B-Frames created using XviD version from 11/2002 to now are or not MPEG 4 compilant.
I explain: I started using XviD from November and I always used B-Frames. They worked fine for me, but I'd like to know if one day, while converting these AVI to MP4, I will get any kind of compatibility issues. And again, is it there an MP4 Transmuxer that support B Frames? I know that Mp4ip cannot at this moment.

I have used packed bitstream in short tests. I found no problems when using XVID decoder, but ffdshow and divx decoder can't handle them correctly. I seems they playback frames in wrong order.
If virtualdub is able to handle packed bitstream correctly it should be easier to edit films with B-Frames. |

Anyway, please keep in mind that packed bitstream did not work with ffdshow when I checked it (half a year ago), but I think this was not my fault because DivX 5.0.2 played XVID packed bitstream without a problem. If DivX cannot play XVID packed bitstream avis correctly, this can have two reasons: a) DivX uses a strange versioning system. XVID tried to imitate this in order to make playback possible with DivX, but I'm not sure if we have updated this to match DivX versions > 5.0.2 b) DivX has often problems correctly playing XVID streams that make use of 4 vector mode. This is also not our fault, but a bug/incompatibility of the DivX decoder. To check if this is the problem, make a test encode with XVID and switch to motion search precision 4 (high). This disables 4 MV search, so if DivX then still incorrectly plays this XVID stream, it could indeed be our problem ;-)) |
