avisynth scripts fail to load in ffmpeg

[barndawgie]

I created a simple one-line AVS script called Test.avs which simply says "Version()". It loads in Windows Media Player correct and plays for 10s dispalying version info for AviSynth.

Even this script fails, however, as an ffmpeg source. Can someone explain to me how to get AviSynth working as an input to ffmpeg on Windows? Detailed output and version info below.

Thanks!

Okay, I was able to figure that one out; I was using the 64-bit version of ffmpeg which apparently doesn't support loading from avisynth.

Now I've hit a new problem: FFmpeg crashes when trying to load an avisynth file containg the DGIndex mpeg2source(*.d2v) command. Any tips? What troubleshooting info is needed?

[qyot27]

Works here*. Post your entire script, and versions of AviSynth and the DG* stuff.

Also, since you realized the initial thread issue was due to the 32/64 split, are you sure the AviSynth-side is fully one bit type? I'd think that 64-bit builds of FFmpeg would load from the [unofficial] 64-bit fork of AviSynth. I can't verify because I don't have a 64-bit version of Windows to test that.


The AviSynth demuxer in FFmpeg got a massive upgrade 3 days ago, so if there are valid bugs found that'd be good to know. I've not found any directly related to the new demuxer, although there are a couple of satellite issues; neither of them are related to DGIndex/DGDecode.

[barndawgie]

I'm running the latest build of ffmpeg (downloaded from Zernaoe builds page yesterday). I'm now running 32-bit ffmpeg which works fine for a script using DirectShowSource but not the .d2v. Using the VOB via DirectShow is causing A/V Sync issues, so I wanted to try using DGIndex in hope that would avoid the sync drift.

The repro is pretty simple. Avi synth file looks like this:

Code: Select all

mpeg2source("D:\DVD_Rips\LA\Life_Aquatic.d2v")

ffmpeg command line is just:

Code: Select all

ffmpeg -i .\Life_Aquatic.avs -loglevel debug

I'm using DGIndex 1.5.8; I can't seem to attach the .d2v (get an error message saying that d2v extension isn't allowed). The log for the run looks clean:

It's probably worth mentioning that this .avs file also will not load in Windows Media Player, but it works fine in VirtualDub 1.9.11

Thanks!

The Windows Media Player issue is probably because of the 64-bit thing again. In that, WMP is probably 64-bit.

Try this build of FFmpeg:

Hi qyot,

I tried that build of ffmpeg and still got a crash.

For the original build, the Windows Application Log shows:
Faulting application name: ffmpeg.exe, version: 0.0.0.0, time stamp: 0x514c556a

This is slightly different with the ffmpeg build you send me, which shows:

[qyot27]

From what Google brought me, it would seem as though the KERNELBASE issue is due to conflicts with UAC and/or permissions or otherwise general User Profile stuff. The recommendation on that is to log in as a different user, rename the first one, and then log back out and back in as the first user so the profile is regenerated.

Try opening the Command Prompt as an Administrator and running the original build (with the KERNELBASE stuff), or moving/copying said build to C:\Users\[YourUsername] and test again. If it errors out in the same way as the build I supplied, it's certainly a permissions issue.

Now, as to why the one in C:\Users says the error is coming from AviSynth 2.5.8, I don't know. Maybe it's also a permissions issue. Have you tried with any builds of AviSynth 2.6 to see if the problem persists there?

I am also having issues with loading an avs file.
It's odd, but if I just use an avisynth script that says version(), it will actually encode, but avisynth scripts that load any kind of file cause it to crash.
I have tested Avisource, Directshowsource, and ffms2, and they all have the same result. Of course the scripts work fine in every other application, and I am using 32-bit everything.

[rogerdpack]

if there's a debug version of ffmpeg and avisynth's dll maybe you could try and track down where the failure occurs?

[Zarxrax]

I did some further testing, it seems to only be broken in the latest builds.
The following build was the last one that works for me:
ffmpeg-1.2-win32-static.7z 27-Mar-2013 23:44 8.2M

Every one after that crashes.
