No process is associated with this object when combining streams

When downloading video and audio separately, i can see both files get created in the filesystem correctly, however then the DownloadAndProcessMediaStreamsAsync method throws a System.InvalidOperationException: 'No process is associated with this object.'

System.InvalidOperationException: No process is associated with this object.

This only started happening in the past few days, nothing has changed, we haven't touched our code since it was last working, videos that worked a few days ago do not work today

Hi.
Does it happen all the time or sporadically?
Does ffmpeg.exe exist in the working directory?

huh strange, i deleted the exe and recopied it in and its working now
Thanks :D

[Tyrrrz]

Hm. Did you notice if the file was corrupted or anything? Really curious why that could be happening.

[itsliamprowse]

Not that I noticed no, its possible though

[Tyrrrz]

Okay. Good thing it works now, I guess.

FYI, we had the same exception. In our case the binary had no execute permission in the docker container. Adding RUN chmod +x some-binary fixed it.
