Please test your system memory with memtest86. also try to download to different drive.Also you should check/try a different ffmpeg version as you're using a different one than the one JDownloader does install

Also please know that the error seems to happen with av1 codec, so maybe in the past you've downloaded vp9 coded streams.

I understand that this is frustrating as it is not reproducible.
I think it is cause by my net.
if it was my memory I would see that with more file like rar files that I download or videos from other sites like vimeo.

the part about different ffmpeg I dont understand how can I change that.
do you mean my system-wide ffmpeg installed with my os package manager?
I installed jdownloaded a long time ago and dont know what version it has.

about the av1 , it is not only av1 if I remember correctly ( as net in my country, iran, is restricted and cant try now) vp9 also has this error.

but maybe I should disable av1 and see it works better with vp9?
as I said in my first report " I tested with vp9 too so I know it is not av1 only."
