Tested with mpeg-2 the sound is racing and chirping. loading mpeg-2 using other filters sound is correct.
| QUOTE | | Fixed the source aspect ratio -- it was sending DAR as PAR. |
Not loading with DAR 16:9 instead loading SAR 5:4 value.
Screen display AR i use 'Free Adjust'
AR 5:4 seen with VDMod_Resize filter used to show exactly what the main display is showing. |

version 0.9
Moving to (almost) the end of a video and pressing the fast forward scene seek results in vdub locking up as it reaches the end

MPEG-2 is looking pretty hopeless from the DirectShow side, I'm afraid. The default Microsoft DirectShow filter that handles it is lousy and has problems such as imperfect seeking and unstable timestamps. I put in some code to try to handle it, but there's not much I can do when the MPEG-2 filter tells me that the video stream is 90 hours long (not joking). You should continue to use input plugins with specific MPEG-2 code for that format.
I've seen the near-end hang and am trying to fix it. It happens when the duration reported by the stream is longer than what the decoders actually provide. I need to beef up the end of stream handling support.

With that info:
As a quick hack, I've reduced mStreamInfo.mSampleCount by 1 seconds worth of samples (or 30 if a sanity check on 1 seconds worth fails)
Like I say, it's a hack, but it works and losing the last second is not usually a problem 
On the plus side, v0.9 is much faster at scene reverse

Turned out to be nastier than I thought... the sample grabber wasn't getting anything on a seek near the end. No NewSegment(), no EndOfStream() calls. I changed the SetPositions() call in 0.91 to explicitly specify an end position and that seemed to fix it. Wish they'd document this stuff....

I'm still getting hangs at the end
Here's a dump of the debug strings for the last few frames when scene forwarding

A nastier problem with .91 is a huge performance drop, with some files
The line
hr = mpGraphMediaSeeking->SetPositions(&startPos, AM_SEEKING_AbsolutePositioning, &endPos, AM_SEEKING_AbsolutePositioning);
in void DSVideoDecoder::DecodeFrameLocal(void *pvFrame)
looks like it's causing some really horrible reseeking every other frame
As an experiment i adjusted LONGLONG endPos = VDRoundToInt64((double)(frame + 2)
to be 50 frames, and the re-seeking delay did appear ever 50 frames then, so that looks like the problem alright
(the delay - especially toward the end of a file can be long enough for virtualdub to give up and report a deadlock)

Hi, phaeron
I have an video that using the WMV Input Driver, by fccHandler, or the FFmpeg Input Driver, by raythe0n, I have not get synchrony, and also for DirectShow Input Driver (the video stay very slow in playback). I will test, when is possible, with apropriate versions DirectShow codecs or filters (knowing if I have them with RadLight Filter Manager v1.5), and don't know if I have the specific codecs for play correctly this (FFmpeg Input Driver plays more than DirectShow Input Driver, but also no get audio synchrony). For can convert it to DVD, with sync, I'm planing to use AviSynth, and some hacks, using also ffmpegsource, and timecodes for can do this. The address of the mentioned video is:

L.H.V.F., firstly 'repair' this WMV file using AsfBin.
After that, it should be sync (when importing through DirectShow import driver or fccHandler's WMV input plugin).

| QUOTE | As an experiment i adjusted LONGLONG endPos = VDRoundToInt64((double)(frame + 2)
to be 50 frames, and the re-seeking delay did appear ever 50 frames then, so that looks like the problem alright |
Well that's just peachy. The audio hang I can solve -- the audio stream needs a slightly different mechanism to handle unexpected end of stream events -- but now I have no clue how to solve the video hang. The filter graph is ignoring my seek request and neither sending a new segment nor an end of stream event, so there's no good way I can see so far to know if the upstream filters are ever going to send me more samples or not. The only way left seems to be a timeout, which is an unacceptable solution.

A "long" timeout (ie few seconds) + a popup windows saying something like "No responce from xxx, is the job complete" ?
It seems ugly, but if you have no other way round, it's always better than being obliged to kill the process (i think).

In this thread you mentioned using graphedit's connect to remote graph feature for a diagnosis
http://forums.virtualdub.org/index.php?act...=ST&f=4&t=20466
Interesting, I hadn't looked at that before, but it does raise a question
In all other directshow graphs, there is one graph and in the graph, you get the splitter and then the 2 rendering paths for audio and video
This plugin gives 2 different graphs, one for audio, and one for video
Is that on purpose? Do the 2 ever get out of sync?

| QUOTE (phaeron @ Oct 23 2010, 09:07 AM) | | I'm looking into modifying the internal ASF driver to have lower priority. Since all it does is output an error message, it's safe to say you would never want it to activate if any other plugin can handle the file. |
Avery, I understand this must be a low priority issue for you, but it is still unsolved after more than a year and that is a bit too much of a wait for me.
You said you will change the internal ASF driver, but I just tested 1.10.1 build 34703 and I still get the same "ASF files are not supported" message when opening WMV.
Will this ever be fixed, or I will have to keep patching every new VirtualDub version to be able to open WMV files through DirectShowSource driver from command line (and from open dialog without having to select directshow driver manually every time)?
