ffmpeg::Error Stream not found

[niklaskorz]

I'm trying to convert the Sintel open movie to AV1 using av1an default settings.

I am getting the following output for tag 0.2.0:

The same happens for the most recent commit 57cbb29

@niklaskorz It doesn't happen for me with the same input file you uploaded, my guess is that your ffmpeg build is somehow too outdated or otherwise misconfigured. Make sure your ffmpeg build has libdav1d enabled (you may have to recompile av1an since it links to the ffmpeg C libraries), since it seems as though it cannot detect the AV1 stream in the encoded chunks (the error means that it could not get the number of frames in the encoded chunk, which av1an uses as a sanity check to make sure that are no frame drops).

[niklaskorz]

I've built the docker image I executed av1an in from the repo's master branch Dockerfile, so the ffmpeg build used is the one from luigi311/encoders-docker:20210901.

I remember we downgraded from luigi311/encoders-docker:latest to luigi311/encoders-docker:20210901 since the latest version was apparently experimental and was causing some problems for us. I just tried luigi311/encoders-docker:latest again but it still seems to have issues for me. @luigi311 will know more about that than me.

For now though you can try masterofzen/av1an:latest, which should work.

[niklaskorz]

I'll try that, thanks!

Yeah seems to be an issue with vapoursynth. I am currently in the process of migrating over to all static builds for it but running into issues with x265 not building statically when including 8/10/12 bit support so i will skip that for now just to get the fix up and then get that building statically later once i get a solution from the x265 bug tracker.
