ffmpeg/libavcodec supports decoding PAFF

[bond]

Thanks to Jeff Downs libavcodec now supports decoding PAFF:
http://svn.mplayerhq.hu/ffmpeg/trunk/libavcodec/h264.c?sortby=date&view=log

enjoy!

http://x264.nl/h.264.samples/ I thought they had this link, but i guess people are too lazy to test.

I am supprised to see MBAFF + Spatial direct mode (Ateme satelite) working.

Conclusion:
USE CoreAVC 1.5.x www.coreavc.com, 15 dollar for the best _and_ fastest H.264 decoder.
Unless you want to wait some more years, then opensource ftw!

you are mentioning a known bug in libavcodec, not being related to paff

With MPlayer r24766:

EinsFestival-HD.1280x720.paff.tandberg.h.264.astra.19e.30.aug.2007.ts -- fails, first frame is displayed correctly, then it says:

[h264 @ 0x8932ed0]decode_slice_header error

Edit: VLC 0.8.6 seems to play this fine, so the problem is probably in MPlayer's MPEG-TS demuxer (-demuxer lavf didn't work either).


08-25_16-27-11_ARTE HD (ger)_.ts -- works perfectly if this is the same clip as arte.hd.ts on bob0r's site

canal.plus.film.hd.poland.1920x1080.paff.25.aug.2007.ts -- fails, same problem as with EinsFestival...

ANIXE.HD.Astra.1G.19.2E.10.jul.2007.ts -- works, but complains:
Interlaced pictures + spatial direct mode is not implemented

ProSieben.HD.HD.Astra.1G.19.2E.10.jul.2007.ts -- works, but complains like with the ANIXE clip.

Conclusion: Looks like PAFF decoding is already working quite well, but there may be some (unrelated) problems in MPlayer's demuxers and in ffdshow.

All of my h.264 PAFF samples have this same error. I was wondering what are the difference in some of these h.264 PAFF samples that don't work and why does the ffmpeg team seem to not worry about fixing it (judging by the ffmpeg mailing list). Thanks..

So I thought I'd try to make PAFF work in DGAVCDec.

I got the latest trunk version of ffdshow_tryouts and it crashes in libavcodec whenever I open a PAFF h.264 (abort due to too many reference pictures).

Is there a good version of ffdhsow_tryouts libavcodec that works with PAFF?

[bob0r]

Its badly supported, maybe you should still make your own implementation.

@neuron2,

i have installed this version ffdshow_rev1602_20071111_xxl.exe and its working for me. i index video with DGAVCindex alpha 2, then change dga files beginning like this:

DGAVCIndexFile3

C:\bits0001.264
C:\Program Files\ffdshow\libavcodec.dll

but some times then i load avs with virtualdub it crashes then i randomly move slider, this is error (if it useful...):
