Transcoding Errors?

[msprout]

Hi all. I have Owncast running in a shared Cloudron environment 10 other deployed apps. The server itself is housed on a Dedicated CPU Linode instance with 8gb of RAM.

When I start sending data to my server, Cloudron logs spit out the following:

Nov 28 14:38:33 INFO[2022-11-28T19:38:33Z] Video transcoder started using x264 with 2 stream variants.

Has anyone seen this problem before? I am a bit confused — the same settings work fine when Owncast is deployed by itself via the pull script on a VPS.

[nebulon]

@msprout maybe the package misses some codecs or should use other variants. Can you take a look at the mentioned data/logs/transcoder.log to get more insight here?

@nebulon Hey Nebulon, thanks for your reply. Here's the content of my transcoder.log file:

[nebulon]

thanks for the logs, unfortunately I can't make out much of those now. But I am neither a codec nor owncast expert. Maybe you could ask the upstream project about this as well as currently I wouldn't even know where to look in our package to make it work

Or since you mentioned, that you have a working instance, are there any logs to compare both and maybe then detect some mismatch from the logs?

[msprout]

@nebulon thanks for your effort anyway.

Just for anyone else, I thought maybe this was an issue with memory allotment making transcoding trip up, but I tried resizing the RAM of my VPS instance as well as the app within Cloudron — no dice. Didn't seem to be an issue that was solveable by switching to another encoder preset.
