Hello Mike thanks for your interest.
This method aims not to use any external script that we have already used, moreover the OBS virtual camera does not have an Full-HD source and this does not allow to have an h265 output with the very high quality using a script.
You can read some posts about this:
The only native h265 method is this, using the encoder directly on OBS, all the others are workarounds that lose quality and therefore also use less cpu.
I am interested in your tests on OBS libx265 or hevc_qsv (libx265) encoder
That's interesting as I appear to be getting full HD out of the OBS camera plugin, at least according to VLC and it certainly looks full HD. However I tend to use lower symbol rates so the limit becomes the channel.
Using OBS camera is a fudge though, as it record, RTMP etc. The internal (non-plugin) OBS camera didn't include an audio channel, when I asked it hadn't even crossed their minds that this might be useful.
It would be good if someone could get inside OBS and get it to produce a TS on it's own, the DATV plugin... the developers seem rather against this whenever I have asked about anything like that though you would think there would be a demand outside amateur use. Maybe it just needs a lot of people to ask.
