Not working with H265 (hevc) streams :(

[TippyLion28]

Works goregeously with the rtsp server I have on my phone for testing, but my IPCAM streams in HEVC which does not play nice. I'm in the process of tweaking with the ffmpeg options but it really doesn't want to play ball. Here's what I'm getting on stderr:

I'm aware the stream URL ends in .264, but I've verified with VLC that it's in fact a hevc stream.

Also, may be unrelated but why does it spawn several ffmpeg instances?

[k-yle]

Hi @TippyLion28 i suspect the two issues are related. Normally only one ffmpeg instance would be spawned per stream.

I can't easily test this, but if I get my hands on a H265 capable camera I'll investigate - possibly next week...
