Error playing Movie 720p BluRay x265 ESubs.mkv #141

Open slumbergod opened 4 years ago

A lot of new releases have video encoded with x265 now.

When the video is loaded in gnomecast it starts re-encoding as expected but when it starts to stream there is no video, only sound. What I do not understand is whether gnomecast's re-encoding is supposed to include files encoded with x265 or not. Shouldn't ffmpeg convert the file into a format that gnomecast is able to stream on all chromecasts older than the new ultra version? Sometimes it is the same with audio...there is picture but no sound. Is this a failure of ffmpeg to correctly choose the right codecs to re-encode?

I'm not complaining. I use gnomecast everyday and in most cases it works flawlessly. I'm just struggling to understand why some files refuse to play video or sound even after the conversion process. Any thoughts?

It depends on the device. Some Chromecasts can play x265, others not. (Seems to correlate to if it supports 4k.). If it thinks it can't it's supposed to transcode back to x264 (which is slow as mud).

But it should never be playing with only sound. If it doesn't support a video format or just doesn't play at all from my experience.

So it could be the software logic that's failing or maybe that our older chromecast misreports itself?

Maybe a future enhancement could be to add an option to simply force x264+mp3, bypassing the software logic completely. It's not common that I encounter this problem but it is happening a lot more frequently because of so many files recently are being encoded in x265 and newer audio codecs.

I know that chromecasts can be notoriously tricky. I still haven't managed to get my firewall configured to let it through.
