Black screen (audio and subs work)
I'm able to cast to my Chromecast plugged into my TV, there is sound and I can see the subtitles, however the video is a black screen. I have made sure all NPM modules are installed, checked that ffmpeg and ffprobe are also installed and in the correct paths.
Ubuntu 20.04.3 LTS 64-bit Gnome 3.36.8 CPU: Intel® Core™ i7-10750H CPU @ 2.60GHz × 12 GPU: NVIDIA Corporation / NVIDIA GeForce RTX 2070/PCIe/SSE2 Using NVIDIA driver metapackage from nvidia-driver-470 (proprierary, tested)
Here is an example of a few seconds of the stream in debug mode:

This sounds like video is in a format that Chromecast does not support. Have you tried casting with transcode video option?
