One thing that could make it more usable for actual testing and debugging would be if the "error" frames also had a listing of which nearby (+-20 frames window maybe) linear access frame(s) have the same hash as the non-linear one.

Thanks Atak

Thanks Atak, me give it a try, Nice addition.

:thanks:

I thought about that before publishing but i wasn't sure if you guys maintaining plugins would really need it. Do you need info about first repeated frame ? For example in my screenshot frame 1 is being injected multiple times

Having an offset relative to the linear access makes it so much faster to spot if it's only one frame off/b-frame reordering issues/something else.

Even if I won't use it every day at least the screenshots posted by other people will be informative...

Neat!

Something like this ?
Error - frame 1 repeated (offset -10)

Looks reasonable

Looks correct or offset should be reversed (positive numbers)?

Flip the sign and it's perfect

Ok. Updated version in first post.

Maybe I'm missing something but I just get SCRIPT ERROR. I've edited FFVideoSource.avs to change the LoadPlugin path...

[Atak_Snajpera]

have you used 64 bit version of ffms2.dll?

[StvG]

Same error SCRIPT ERROR with Avs+ 3.6x. No error when using Avs+ 3.5.

[wonkey_monkey]

I'm on 3.5. I have both versions of ffms2.dll and I'm pointing to the right one in my template (I assume 32-bit since Seek Tester is 32-bit).

[Atak_Snajpera]

Have you tried 64bit version?

[wonkey_monkey]

Same thing happens.

[Atak_Snajpera]

What if full path where you extracted seektester?

[wonkey_monkey]

Was in Program Files (x86). Moved to Desktop, but same error.

Looks good! Thanks.

Thank you.

Can you please make the window resizeable? The start button gets buried under the taskbar. On Win7.

Bug report: you're more or less thread bombing systems with many cores

I didn't look at the internals but you seem to spawn one ffmpeg instance and effectively one ffvideosource instance per thread in system (I know you can limit the decoding threads in the script but that's not the default). Both ffmpeg and ffvideosource will in turn spawn as many threads as are available each. So if you have a system with 32 threads you get 32 * (32 + 32) threads and probably 32 more for the linear decoding. ~2080 threads! Or ~1000 threads if you do single threaded decoding.

You see the problem and accidental ways to make it worse. Solution:

Add a configurable number of threads and make it a template variable too. For example 4 threads would be a sane default. Note that the number of threads may affect the decoding result so having it as an explicit option is generally good. Also change the number of instances depending on the number of threads selected. For example if both ffmpeg and ffms2 uses 4 threads then only spawn system threads/4 instances to keep things sane.

Drag and drop would also be nice.

I get "SCRIPT ERROR". Tried 32 and 64 bit video source plugins. Windows 7 64 bit, AVS+ 3.4. How to make it work?

Double click on script error message

Double click on script error message
Thanks, that helped to solve it.

Idk what I'm doing wrong. Extracted 7z. set path of ffms2.dll, clicked on save.

Win10 x64, Avisynth x64 3.6.1 (r3300)

What filetype are you trying to open?

[Atak_Snajpera]

Personally I'm still using avisynth+ 3.4 x64. Perhaps your newer version 3.6.1 does not recognize framecount argument?

there was bug in AviSynth+ 3.6 that was fixed in AviSynth+ 3.6.2-test2, you can try AviSynth+ 3.6.2-test4

Yes. 3.6.2 test4 should work. See Avisynth+ topic first post. There were issues when you had GrunT dll around.

[ChaosKing]

Yep 3.6.2-4 fixes it.
