The assert looks like an async call not getting completed... a problem, but it shouldn't affect audio as that's on an entirely separate engine. Haven't seen that one before... any idea what's tripping it?
The audio situation, however, is a mess. Here's what I'm getting out of the WMA decoder on a test file:
| CODE |
SampleGrabber[audio grabber]: Raw receiving [24480000, 25120000]
SampleGrabber[audio grabber]: Raw receiving [25120000, 26400000]
SampleGrabber[audio grabber]: Raw receiving [25250000, 26190000]
SampleGrabber[audio grabber]: Raw receiving [26190000, 27470000]
SampleGrabber[audio grabber]: Raw receiving [27440000, 27780000]
SampleGrabber[audio grabber]: Raw receiving [27780000, 29060000]
SampleGrabber[audio grabber]: Raw receiving [29350000, 29990000]
SampleGrabber[audio grabber]: Raw receiving [29990000, 31270000]
SampleGrabber[audio grabber]: Raw receiving [31400000, 32280000]

The timestamps are basically garbage -- gaps between some samples and overlap with others. One of the samples is even entirely inside one of the others.
The reason the audio drops out is that the plugin is returning 0 samples to VirtualDub, which then causes the audio path to stop. That could be fixed by some dummy data, but it won't fix the problem that timestamp-based sync is just unworkable with timestamps this unstable and the audio will be full of glitches anyway. Another strategy would be needed here.

no idea about the cause
I've been playing with different workarounds and almost gave up on wmv as a format
Tried using ffmpeg to convert the audio, copy the video and output a new wmv file
The audio still stops when that assert is hit
Tried using fcchandlers wmv plugin to load the original and the converted one
<=v2.6 gives lots of garbage audio, and >2.6 is broken for pcm audio (in the audio view, the display barely moves by the time the video if half way through, oh and it crashes a lot as well access violation in ReadData)
Unfortunately there's a lot of changes between 2.6 and 2.7 - too many for my limited time and c++ knowledge so far
Avisynth works fine though
Soooo....
Ended up with a script that-> ffmpeg copys the wmv to a new wmv with pcm audio, creates an avs script and adds it to the queue to be converted into lagarith, which gives me a workable editing solution
- the convert to pcm is just to stop any sync errors that always seem to creep into avisyth with its directshowsource
It's hacky, but so far it's reliable and glitch free

Interestingly enough I was able to convert the MOV to AVI with MP4CAM2AVI (using "direct stream copy" for the video encoding, so no change) and VirtualDub would load that avi then.
Just a problem with the mov-container? |

Do you have a splitter installed that can handle them?
LAVFilters splitter or Haali media splitter can
https://code.google.com/p/lavfilters/
http://haali.su/mkv/
On win7 or greater, you may need to change it's preferred decoders with Windows7 Codec Chooser (link in my sig)
Change them from the windows own ones to FFDshows for any that don't want to play nice

Thanks for your fast and detailed response.
I have Haali media splitter installed. (WinXP)
Uninstalled it. Installed lavfilters. That works.
Thank you for your nice work. |

After a fccHandler MKV input plugin failed to detect AC3 5.1 audio in my file:
http://forums.virtualdub.org/index.php?act...ST&f=15&t=21813
And ffMpeg input filter failed to work:
http://forums.virtualdub.org/index.php?act...t=90#entry94243
...I resorted to DirectShow input driver. That did work... for a second. I cuting and exporting from movie a small part of it, with added subtitles and little downsize...
And I get about 1sec of the audio, lol.
Not exactly good, but whatever. So I reporting my fail.
The file is 4.6G in size (The Running Man.mkv) and I can upload it somewhere for testing, but don't know where (okay, the czech ulozto.cz site will work and even for english guy is the downloading just a matter of the captcha and wait, it goes in free mode at about 300k) to put it and where to place the link, as this is basicaly a copyrighted material.
PM perhaps?
So is there even interest to look at this?
(the encoded part if MUCH shorter, yet like I say, the audio is only for second, then it's volume get down to zero... http://www.sendspace.com/file/o6cijz )
