yes, but remuxing introduces new errors on other places of the stream due to skipping of frames while demuxing (mplayer, h264to etc. tested, all the same result, so no remuxing is the way i chose).
i will report the decoding bug |

@ chros Yep, but after I've taken whole lot of them, I convert them to pngs - that's twice the work, but saves a lot of hdd space (especially when running more passes during the conversion - 2nd one already does some extra packing, the difference is rather large). Update! Revision 891 - Directory Listing Modified Tue Feb 6 16:43:33 2007 UTC (8 hours, 40 minutes ago) by clsid2 Fixed grabbing to PNG. Ta. @ fastplayer Thanks very much for the info. Unfortunatelly the latest revision of clsid's sse icl9 is 885 (poped out today I think), so there's no reason for me to upgrade, since I can confirm that sse icl9 utilizes less cpu with various filters than any other compilation. I've gotta wait a while then.

PS. When I play with settings, sometimes the auto mode works all right, sometimes not, I've just marked. Nevertheless libav + XviD MMX iDCT is the only one 100% without bugs (apart from crappy decoding of packed bitstream, but that's another story). cheers, HDBR77

Hi guys, I was just wondering whether is there any ffdshow build that supports multithreaded h264 playback? I have a 1920x1080 video that does 50% of CPU Usage and I've checked in Task manager that it maxes out 1 core and leaves the other un-used.

By all accounts, the MP4 container is the perfect partner for MPEG-4 AVC streams. And has far less overhead.

i also like the mp4 container, but if i demux the stream and pack it into mp4 (MP4Box -add part1_video.h264#video:fps=25 part1.mp4) the video is not playing smoothly (haali splitter or gabest splitter with coreavc, ffdshow...). in a mkv container it plays fine but shows some errors on other locations than the ffdshow crash (which remains at the same location btw. no matter what container).
i do not seem to get answers on my bugreport on the ffmpeg list :/ |

Hmmm...
Just to be certain.... Are you using the newest versions of MP4Box. And are you making sure the frame rate speed of your MP4 matches the sources frame rate speed?

Sadly I can't test/play such high resolutions AVC sources with my "slow" PC.... Which is a real bummer

Sample
@ haruhiko_yamagata:
I've cut a short sample, just uploading it + some more png screenshots. I will update my post, when I'm done. http://xasonline.info/headbanger/ffd...arl.Sample.avi http://xasonline.info/headbanger/ffdshow/ffdshow.rar cheers, HDBR77

I can't notice the difference between IDCT set to libmpeg2 or Xvid MMX... The distortions look bad to me with both settings (look at Keira's chest @ 0:24 and 0:33min). Am I missing something here?

PS. If it's the chest alone, then you could be looking at XviD encoding of dark scenes in its worst, though CC was added, and Didee's SixOfNine throws quants 2-3/3-4.

The time-range you've given is full of decoding errors with libav + libmpeg2 - she looks as if an alien was trying to get out from beneath her skin.

Blah - you can compare the screens, I've uploaded them, so you will know for sure what I'm talking about all the time.

Still, there's one thing which has just come to my mind:
1) I can decode the above sample properly via ffdshow using either XviD 1.1.2 library or libavcodec with manually set XviD MMX iDCT - clsid's svn 843, sse, icl9. 2) Fastplayer can decode the sample properly only when using XviD library. Libavcodec + libmpeg2 idCT and libavcodec + XviD MMX are both causing artifacts - rev. ??? Another difference between builds? Shouldn't be - if both the decoding library and iDCT are set manually.
