vsrawsource - Raw Video Reader for VapourSynth

[feisty2]

okay, I been messing with gdb for the last 1.5 hours and still got no clue about how to get it to debug, literally.
so I made a broken binary of Chikuzen's original code
here: https://github.com/IFeelBloated/vsra...eases/tag/test
a little help here, tell me what I'm doing wrong plz?

[jackoneill]

Make sure to add

-ggdb -g3 -O0

to the CXXFLAGS and don't let it strip the DLL.

gdb --args <command that crashes>
run
bt full

This prints the sequence of function calls that led to the crash, with the most recent at #0. It should give you the location of the crash as a file name and line number.

[feisty2]

sorry for the dumbness but, I'm still confused with gdb, like, what kind of command do I have to put in "<command that crashes>", sure it can't be that core.raws.Source.... vaporsynth command, right? it crashes vaporsynth if you try to load any file with core.raws.Source (...)
I updated a new broken x64 binary with debug symbols, someone kind plz, help me do the gdb test.

[Are_]

Something like "vspipe.exe something.py -"

[feisty2]

okay, it got stuck like this for, 15 minutes.
what does it mean?

1.vpy
import vapoursynth as vs
core = vs.get_core()
clp = core.raws.Source("1.rgb",720,576,src_fmt="GRAY16")
clp.set_output ()

[jackoneill]

It means there was no crash.

[feisty2]

but 1.rgb is only about 30MB, vspipe should've done the work within seconds, not stuck for 15 minutes, and when I terminated vspipe.exe in taskmgr, t.rgb was still 0kb

and I loaded 1.vpy in vseditor and tried to preview it, it got stuck as well and taskmgr told me it stopped responding

Can you host your sample file somewhere and post exactly what your script is? I can try to help you diagnose your issues.

[feisty2]

1.rgb https://mega.nz/#!FxIRHZRS!l_Vu7N_0A...BSyK0pemTgDDtY
1.vpy

import vapoursynth as vs
core = vs.get_core()
clp = core.raws.Source("1.rgb",720,576,src_fmt="GRAY16")
clp.set_output ()

1.vpy vspipe.exe are in the same folder with 1.rgb

edit:
and broken x64 binary with debug symbols https://github.com/IFeelBloated/vsra...eases/tag/test
in case you missed #21

[sl1pkn07]

works for me in linux (64 bits) with original code, with vsedit and pipe method

you clip is only 35frames?

[feisty2]

Yeah, 35 frames just for test

[sl1pkn07]

then works ok for me

EDIT: oh. wait. i use this fork https://github.com/myrsloik/vsrawsource

sorry :S

[feisty2]

Maybe I should uninstall windows and take Linux instead?
Okay, I'm joking...
But I can't get it to work on windows with gcc

[sl1pkn07]

and with clang?

[feisty2]

Didn't test with clang, but it's 10am now and I'm going out and I will test it and report back when I get home

[feisty2]

@HolyWu
still not working, I think my gcc might be corrupted, I'll reinstall it and report back

[feisty2]

reinstalled gcc and things worked out alright, finally
so, new version here
v0.3.3
update: added support to GrayS (tested) and GrayH (not tested, cuz I can't find any float16 clip and fmtc got no support for GrayH so no way to test)
https://github.com/IFeelBloated/vsra...ases/tag/0.3.3

I have fixed a bunch of bugs in vsrawsource and almost done adding tests. Also I have added capability to read from a pipe (not tested on windows yet).

I have not compiled or tested on windows yet, if you want to help go for it.

Can you please give me a hand on the shell pipes (in Linux)? Surfed through a whole lot of sites and still unsuccessful. Here is what I try to do and it doesn't work.

video = core.raws.Source(sys.stdin, 1920, 1080, 30000, 1001)
# Here goes some processing
video.set_output()

Command line:

ffmpeg -i input.mts -pix_fmt yuv420p -f rawvideo - | \
env PYTHONPATH=/usr/local/lib/python3.4/site-packages vspipe --y4m proc_vs.py - | \
ffmpeg -i pipe: output.mkv

The error I get:

Script evaluation failed:
Python exception: 'utf-8' codec can't decode byte 0x80 in position 7291: invalid start byte
