I'd like to report a little bug. Initially reported as a MPC-HC bug by someone else, but it looks like to be a Lav Splitter bug instead.

The installer doesn't check for x64 before installing IntelQuickSyncDecoder.dll.
Code:
Source: bin_x64\IntelQuickSyncDecoder.dll; DestDir: {app}\x64; Flags: ignoreversion restartreplace uninsrestartdelete skipifsourcedoesntexist; Components: lavvideo32 Code:

Lav Audio has nothing to do with this. It's all about the splitter. It hangs/crashes with 0.44.

There was a bug that caused it to never output any audio when lav audio was used, which i fixed. That was also the original bug report.

You're right, I take it back. Normally I only use MPC-HC, but after having tested the wav-file in Zoom Player and with MONOGRAM GraphStudio, where it plays perfectly fine, I have to conclude that MPC-HC is indeed the culprit, like the guy said.

But, it works fine in MPC-HC for me.

nev, when seking in this VC-1 file using QS the image freezes. It doesn't hang the player, but it doesn't recover either.

Anyway, updated drivers and it works now. Didn't think it would make a difference since ffdshow used to work before. |

Do you have Lucid Virtu installed and and playing using the 64 bit version? If so, then it's a lucid Virtu bug. Somehow it's mixing the frame order. 32 bit was fine (on 64 bit OS).

@nev
ftp://132.185.142.44/video/maybefina...romo-tr1500.ts plays way to slow (8 FPS) compared to VLC also can you please add wma lossless to lav audios selection (WMAL) option so that it wont try to playback streams with it and fallback to wmaudio decoder accordingly http://roundup.libav.org/issue421 putting wmaudio decoder above lav audio works too but it's not the correct way of handling it

I have this often with lossless codecs, where the VfW codec is multithreaded, but the Dshow (Libav, FFmpeg) version is not. Also the VfW is often more optimized then the Dshow version. (UTVideo, Lagarith,...) Because you're using directshowsource, you 're basically using the Dshow version, so the speed difference is not clear to me; the avisynth way should not be noticeble faster unless using MT version....

Intra-only codecs are usually very easy to multi-thread in decoding, because every frame is "stand-alone" and doesn't have to wait for the previous reference frames to be decoded.
Multi-threaded decoding was just recently added to ffmpegs UtVideo decoder. Adding the same for DNxHD would probably be rather easy, someone just has to do it.

QS decoder rev20 is committed.
Changes are: Added MT copy. A mild performance gain. Added flag to disable it Fixed bad seeking in VC1 (nev's report). On every seek in every codec, the entire session is destroyed. Works smoothly. Added flag to report a corrupted frame (what MSDK reports). Cosmetics. FYI, I'm not building a version myself ATM, I want to address 2 other issues. One of them is VC1 decoder sends the same buffer over and over with different time stamps which breaks my code.

Problem is opposite what you described. I wrap ProRes into AVI and when it's loaded to some application- eg Premiere it works slow. If I load it through avisynth (directshowsource) using fake AVI (virtual file system for avisynth) than it's fine- all cores are used. Not sure why it's happening.
