Avisynth preview problem

[kingcrimsonster]

I loaded a file with 5174 number of frames into Hybrid. Avisint preview only shows the first 123 frames.

Don't see any errors, try another source filter.
If that doesn't help, it is probably a bug in the source, try remuxing it with mkvtoolnix beforehand.

Did not help.

Please note: Mediainfo and the Hybrid itself show on the tab [Base] - Top field first.
But on the tab "Deinterlace - QTGMC - Avisynth - order = 0 : Bottom field first.
Maybe that's the problem?

[Selur]

Nope, that will just cause stuttering if you bob.
"QTGMC (Avisynth)->Order" should have been removed (it's not present here) in 2024.05.05.1 (ahh,.. only for Vapoursynth, removed it for Avisynth later)
=> I'm confuses, since the debug output stated you are using '2024.07.12.1',...

If switching the source filter didn't help, then it could also be no issue with the hardware decoding.
Does using Vapoursynth show more frames?

Can you share a source which causes this with me?

No, Vapoursynth show 123 frames.

Using FFMS2/FFmpegSource2 in Avisynth and Vapoursynth I see all the frames.
Using other source filters seem to have problems with the source.

When I check Prefer FFmpegSource and press "avisynth preview" - appear:

Avisynth preview error: -> Histogram: Levels mode only available in PLANAR. (K:\temp\tempPreviewAvisynthFile21_28_49_977.avs, line 29)

After uncheck "Show Histogram:" avisynth preview now show all the frames.
If I uncheck both checkbox LibavVideoSource instead of FFmpegSource and FFmpegSource - how can I find out what filter the Hybrid uses?

[Selur]

I can reproduce the histogram problem in Avisynth, which happens since for some reason Hybrid uses YUY2 instead of YUV422P8 and the code generation while adding histogram didn't take into account the restrictions of mentioned over at http://avisynth.nl/index.php/Histogram.
=> I'll look at it.

Selur, please fix error:
Before load this file I set on the tab "Deinterlace - QTGMC - Avisynth - order = -1 : from source headers (default)."
After load this file on the tab "Deinterlace - QTGMC - Avisynth - order = 0 : Bottom field first."
When I try to view step by step, the image goes one frame back and the next one forward. If I encode in this mode, the output file has vertical jitter.

QTGMC has no 'Order' indication anymore:

removed that a while ago.
Uploaded a new dev to the 'experimental'-folder of my GoogleDrive.
Which should add appropriate color space conversions for 'Histogram'.
