Got Hybrid installed on Arch through the AUR. When I load a video ripped from a DVD, I get "this file could not be recognized error"

Hybrid 2025.11.09.1
2026-02-20@13_10_00_4610_08_muxing crashed: ERROR: /home/d/_2026-02-20@13_10_00_4610__08.mp4 was not created!
Added the MKV, set audio to custom. AAA 192k. Preset slow, tune psnr. Added job

the debug output does not contain the error, so no clue why that happens.

No clue where the "Not ready, retry later" is coming from, you can try calling the call inside a terminal.

Quote:Got Hybrid installed on Arch through the AUR.

I have no control over the arch, try the AppImage dev version. (there I know that the binaries should work)
Try removing special characters from your file name.

Cu Selur

I tried the AppImage on the downloads page and the one in you Google Drive, neither would open. No error, just wouldn't open at all.

Okay, it worked for others on ArchLinux.
No error, nothing.
I have no idea, how to tackle that. Sad

(you set the file executable, right?)

Cu Selur

I did set the executable.

I installed another Arch distro, Endeavour and tried the same file again. The Google Drive appimage worked with Endeavour. I used the Manjaro install for Vapoursynth and that worked. Tried the video again and got the same crash error as before. Did deinterlace with no Xsynth and it worked.

I got the same crash error with all of the Vapoursynth options.

Does the Vapoursynth Preview Work?
Did you install all the filters and scripts for Vapoursynth that you need?

Looking at the debug output again, there is also:

Code:

with 'y4m [error]: bad sequence header magic' which usually happens if the Vapoursynth setup has some problems or the Vapoursynth script has a bug.
Looking at the Vapoursynth script:

Code:
# Imports

import vapoursynth as vs

# getting Vapoursynth core

import sys

import os

core = vs.core

# Import scripts folder

scriptPath = '/usr/share/hybrid/VapoursynthScriptsInHybrid'

sys.path.insert(0, os.path.abspath(scriptPath))

# Import scripts

import 

import validate

# Source: '/home/d/Videos/S1.E3 ∙ Part III Chapter 5.mkv'

# Current color space: YUV420P8, bit depth: 8, resolution: 720x480, frame rate: 29.97fps, scanorder: top field first, yuv luminance scale: limited, matrix: 470bg, transfer: bt.601, primaries: bt.601 ntsc, format: mpeg-2

# Loading /home/d/Videos/S1.E3 ∙ Part III Chapter 5.mkv using LWLibavSource

clip = core.lsmas.LWLibavSource(source="/home/d/Videos/S1.E3 ∙ Part III Chapter 5.mkv", format="YUV420P8", stream_index=0, cache=0, prefer_hw=0)

frame = clip.get_frame(0)

# setting color matrix to 470bg.

clip = core.std.SetFrameProps(clip, _Matrix=vs.MATRIX_BT470_BG)

# setting color transfer (vs.TRANSFER_BT601), if it is not set.

if validate.transferIsInvalid(clip):

  clip = core.std.SetFrameProps(clip=clip, _Transfer=vs.TRANSFER_BT601)

# setting color primaries info (to vs.PRIMARIES_BT470_BG), if it is not set.

if validate.primariesIsInvalid(clip):

  clip = core.std.SetFrameProps(clip=clip, _Primaries=vs.PRIMARIES_BT470_BG)

# setting color range to TV (limited) range.

clip = core.std.SetFrameProps(clip=clip, _ColorRange=vs.RANGE_LIMITED)

# making sure frame rate is set to 29.97fps

clip = core.std.AssumeFPS(clip=clip, fpsnum=30000, fpsden=1001)

# making sure the detected scan type is set (detected: top field first)

clip = core.std.SetFrameProps(clip=clip, _FieldBased=vs.FIELD_TOP) # tff

# Deinterlacing using QTGMC

clip = qtgmc.QTGMC(clip, Preset="Fast", TFF=True)# new fps: 29.97

# Making sure content is preceived as frame based

clip = core.std.SetFrameProps(clip=clip, _FieldBased=vs.FIELD_PROGRESSIVE) # progressive

clip = clip[::2] # selecting previously even frames

# set output frame rate to 29.97fps (progressive)

clip = core.std.AssumeFPS(clip=clip, fpsnum=30000, fpsden=1001)

# output

clip.set_output()

itself looks fine to me, but Hybrid relies on all needed Vapoursynth filters&scripts to be installed. (calling the Vapoursynth Preview should show whether there are problems or not,..)
