Re: SVPcode transcode FAILED

This means ffmpeg's nvenc encoder doesn't work in your config.
We can do nothing about it.

Re: SVPcode transcode FAILED

Thanks for explaining.
However, I have also tried to do it with software encoder,
but I just got the same error.

If it failed because of my config,
how should set my config so it won't fail ?

(by the way, the temporary file it generated is playable but with no media info. when i played it with mpv, it seemed to
continuously  loading and the time left of the movie kept
lengthening.

Re: SVPcode transcode FAILED

my bad - i just saw words "nvenc" and "error" in the same log and made a most obvious conclusion big_smile

after further reading, "../ta/ta.c" is a part of mpv (not ffmpeg), and last time google saw this error it was about some issue with OGG audio stream parsing, but it was fixed 3 years ago
your file has ogg (vorbis) audio too, so it may be the problem
again, the problem IS NOT in SVP, and we can't fix it

can you playback this file with mpv?

Re: SVPcode transcode FAILED

yes, i can.
the test.SVP.temporary.mkv is playable and everything seems normal.
https://drive.google.com/file/d/1Z_p7EkRVunUEVPCwzc60B7_6qO4VTkyG/view?usp=sharing
except that the "00:00:16" time left bar seemed to dymanicly loading.

(so it would be alright if i remove OGG audio stream(?

Re: SVPcode transcode FAILED

I mean the source file, with the audio stream.

Re: SVPcode transcode FAILED

What should I do to make it right?
I am really new to this.
and also thanks for all your help!

Re: SVPcode transcode FAILED

can you playback the source file - /mnt/AAB603A4B603705D/youtube/test.mkv - with mpv w/o errors?

Re: SVPcode transcode FAILED

sorry, what is w/o error(?
(a pure newbie here
I am not sure what you meant
but i played it through command line
the log

[kevin@ArchLinux youtube]$ mpv test.mkv

 (+) Audio --aid=1 (*) (vorbis 2ch 48000Hz)

Exiting... (End of file)

the sound worked fine when i played it

Re: SVPcode transcode FAILED

without errors

Re: SVPcode transcode FAILED

Oh yes, it played without errors

Re: SVPcode transcode FAILED

dunno then... try the source file with different audio format
again, not our error

Re: SVPcode transcode FAILED

I know. It's definitely not your fault.
I really appreciate your help!

about " try the source file with different audio format "
i have also used another youtube video with aac.
it failed..

One thing I am confused is that --noaudio option is on, how does audio format matter(?
just asking, because my lack of knowledge. Never blaming you or something, I am really grateful.

Re: SVPcode transcode FAILED

> how does audio format matter(?

maybe it's not related at all
but the only issue with the same error found on Google is about ogg audio stream
https://github.com/mpv-player/mpv/issues/3432

Re: SVPcode transcode FAILED

so sad..

Is there another way to use svpcode on arch linux(?
I really love this tool..

Thanks for your time!

Re: SVPcode transcode FAILED

A few other people, including me, started to get this issue again: https://github.com/mpv-player/mpv/issue … 536125609.
It appears to be related with vapoursynth as a whole when used with mpv, instead of SVP alone.

Re: SVPcode transcode FAILED

Seems fixed now, and it was completely unrelated to SVP wink
