H265 support, why not?

[giuseppegambino92]

Hi, I wanted to understand why the H.265 format is not supported, and possibly understand what the incompatibility depends on. Eventually I could also move to make a commit request. Thanks in advance

[ioppermann]

H.265 is basically supported such that you can pull it in e.g. from a camera, but you need to re-encode it to H.264.

For HLS playback, only H.264 is widely supported in clients (browsers). Theorically it is possible to have H.265 in a HLS stream (with fragmented mp4 instead of TS), but on some platforms/browsers/players it's not supported.

I just got a new camera and it's H265 for rtsp. I also believe that youtube supports accepting h265 as well. Anyway to make this work?

Hello hemna

I am not sure if YouTube works with h265. You would have to check.

Install the latest Restreamer and try this.

Then you can transfer your stream to YouTube via the publication service.

It's up, but I think it's pulling h264 from the source.

This should be in the log files, aka—process details.

If you want, you can send the two files. I will take a look at it.

The banner file should be enough.

Here you can see where to do it:

Here is the banner. It seems to work for a bit, and then packets fall off until ffmpeg restarts then it works again. That repeater pattern takes about 35 seconds.

Thank you.

I'll take a look at it tomorrow. As far as I can tell, YouTube does not support H265.

This is what the documentation says: https://support.google.com/youtube/answer/1722171?hl=en#zippy=%2Cvideo-codec-h

[hemna]

Thanks, It would be nice to see the actual ffmpeg command line args that were used to start ffmpeg. I'm trying to figure out why ffmpeg dies after 35 seconds

[svenerbeck]

Hello hemna

The banner looks excellent. You can see that H.265 is converted to H.264.

After more intensive research, we found this for you. YouTube can receive H.265 over HLS.

You can see it here: https://developers.google.com/youtube/v3/live/guides/ingestion-protocol-comparison

It does not work via the Restreamer UI at the moment. So we always convert H.265 to H.264.

If you want to do that, you can, but you have to take the datarhei Core and make the appropriate adjustments yourself. The datarhei Core is here: https://github.com/datarhei/core

[Pimmetje]

I would love to have a option to copy h265. VLC is able to play it. So i can play H265 camera's on multiple location without transcoding. As that takes a lot of resources.
