Natron can't read WebM files

Software Natron
1

I’m using
Natron version 2.4.3 Release.

If i try to read any webm file i’m greeted by the same eroor message:
Read1 error: FFmpeg Reader Failed to decode packet: Invalid data found when processing input

the webm file are working just fine in any other Programm. I can also export as webm without problem but can’t read them.

On what platform? (Win/Mac/Lin)

I’m able to read webm files on Windows using Natron 2.4.3.

I tried it on Widows 10 and then on Ubuntu 22.04.

It’s possible to read them(on only some frames), but i cannot use them when im rendering

:thinking:

Thanks for the additional info.

Can replicate the issue with the video you posted. It seems ffmpeg/Natron has issues with vp9, as the webm videos I have is vp8 and seems to work fine in Natron.

I highly recommend using image sequences as input, they are more stable and will in general give better performance. ProRes (in MOV) is the only video format I can recommend in Natron.
