VC1 clip does not work with LAV video decoder
This VC1 clip (from Bleak House) fails to play from MPC-HC when using the LAV Video decoder (also fails with MadVR video decoder). It plays fine with the WMVideo Decoder DMO.

Edit: After looking at the file, i'm sure its interlaced. Use the MS decoder.

Is there a way to set the LAV decoder to only decode non-interlaced VC-1? Because otherwise it seems kind of useless to include VC-1 decoding at all, since it messes up the filter preferences. To clarify, if I put LAV Video decoder at the top of the filter list in MPC-HC, so it gets used for anything it can do, then WMVideo Decoder DMO beneath it in the filter list, is there any way that I can set things up so LAV Video decoder handles non-interlaced VC-1, but it automatically lets WMVideo Decoder DMO handle interlaced VC-1? |

No - it is either On or Off for VC-1 decoding & I thought it was off by default in LAVVideo. Another choice is that if you have a nvidia card you can enable CUVID Mode as it handles VC-1(i) perfectly fine. FYI - there were some post a few weeks ago about the addition on VC-1(i) support in libavcodec....

File takes a second to load, and then goes to end. Lagarith is a bad lossless codec though. ffmpeg probably doesn't implement it correctly. edit: http://forum.doom9.org/showthread.php?t=86148&page=7 , I guess it does, sorta. Last edited by ruinevil; 17th November 2011 at 05:04. |

There have been a few patches for Lagarith the last week or so, which are not yet in LAV Video, and might improve the situation. However, the speed issue remains, its right now neither SIMD'ed nor multi-threaded. (As i understand, its a intra-only codec, so multi-threading should work pretty easily?)

Hmm where are the problems with Lagarith i have some recordings from the last version and they so far all work decoding is not as performant as the vfw decoder but @ least watchable, maybe it's more a problem with older streams ?

That feature has been moved further into the future, alot of other things to do - and honestly, such Intel CPUs that support full hardware decoding are fast enough to decode anything you throw at it anyway - without even breaking a sweat.

Hi,
I posted this issue in the MadVR thread however Madshi concluded that this is not a MadVR issue but possibly a splitter issue. The problem I'm having is playback of blu ray via the index.bdmv or the mpls file. Playback is very choppy, with MadVR reporting 100's of dropped frames within minutes. Madshi has concluded that it's a timestamp issue, and that MadVR is receving frames with duplicate timestamps. The odd thing is though, if I play the m2ts file directly then playback is perfectly smooth. Would be grateful if someone can help pinpoint where the problem might be? EDIT: I just tried playback using MPC-HC's internal splitter and playback of index.bdmv and mpls files is absolutely fine, using LAV splitter and I get the issue above.

Here is a test build, with fresh ffmpeg:
http://files.1f0.de/lavf/LAVFilters-...7-g56a1605.zip Nothing noteworthy in there, just to make sure no regressions appeared - and one build before i start working on stuff that won't be ready for a while.

Maybe your remuxing tool did a poor job? I've only ever played BD discs, and i really have no huge interest in testing all BD ripping software out there. In any case, try with this version: http://files.1f0.de/lavf/LAVFilters-...1605-debug.zip Its a special debug version that should leave log files on your desktop. Note that it empties the log everytime its run again, so play it once and save the log somewhere. Both LAV Splitter and LAV Video logs could be of interest. (If you're not using LAV Video, please try for the sake of getting a log)
