I streamed on twitch for 2hours just for testing. I was pretty impressed. Figured if there were any issues it would show up after a few hours. No issues. Using an i5-2500@4.2ghz and my old amd hd7950 . Wasn't bad at all at 3k bitrate, 720p@30fps

We need a Linux compatible SDK first. I haven't gotten too far into reverse engineering the runtime yet.

One good thing is the kernel 4.7 I'm using has amd vce 1.0 support built in. Just need better drivers and of course the linux sdk.
Keep up the good work Xaymar !!!!.

Straight up impossible. You are most likely using the version bundled with OBS and didn't update - otherwise post a log with Debug Tracing and video.

First .. thx for this great Plugin!.....

I just want to ask .. .until when we can guess the support of hevc/h265? ... From what depends on it? AMD Driver? Or the Plugin? ...

Furthermore i would like to ask what i really can expect from hevc? There are on this subject again and again different Statements. Now i know Twitch does not support hevc,yet. But now when i could stream in a better Quality ... that would be nice. At the moment i have 4 Mbit upstream which i can use. I am streaming with a bitrate of 2500 and with that .. i use most of the possible upstream. Quality is good but whatever i am doing is not enough to avoid blocks.

Its not possible for me to get a better upstream. 25 Mbit (DSL) is the best what i can get here.

My thought would be that hevc could really help to improve stream quality. I am right?

My Graphics Card is a RX 460

Best regards
Surl

PS: Excuse my bad english .. i did my best with the help of google translator ...

HEVC support depends on multiple factors:

  • Widespread Support
    HEVC/H.265 is currently less supported by the mobile market than VP9 is and it will probably be another 5 years until it makes a mainstream appearance. Same thing happened with AVC/H.264.
  • Better Streaming Protocols
    FLV/RTMP currently only support AVC/H.264, until that changes HEVC/H.265 won't get any good support from Streaming sites or similar. The largest ones here are probably Twitch and YouTube which would have to be the first ones to switch over.
  • OBS Studio needs to support H.265
    I'm not sure if it already does, since it uses ffmpeg for muxing.
  • Driver Support
    HEVC encoding is already there if you decide to use Windows Media Foundation Transcode - one of the worst options ever because it's rather undocumented and weird. Right now, HEVC does not seem to be supported yet by AMF, so there is only so much that can be done on my end.
So it depends on the following: A new streaming Protocol, Device Vendors (especially mobile devices), Streaming sites, OBS Studio and AMD. Support for HEVC is technically already built into the plugin, so there's not much to do there.

At a bitrate of 2500, it's better to use x264. Hardware encoding will probably take a long time before it gets better at what it should be good at.

Mmmm the h264 codec is now .. more than 10 years old. Why is it so difficult to do that in Hardware with good or better performance. I cant understand that ....

And development of RX 460 ... has not started 10 years ago.

Why is it so much more difficult to do that in Hardware (same Quality and Bitrate)?

Forget about patents - it's business and technology difficulties. Camera makers should be the first of all - it's portable devices for making videos. Or camera sales will fail again as only pro studios be able to shoot and deliver new quality content.

Is there plans to add tips to all options in the plugin (abbreviations at least, few left)? Because I see no significant changes and old translations gone. Screens missing (translation of the new options, please, check crowdin site comments).

Patents make up 90% of disputes in software development. He stole this, I had this idea first, etc. Once a patent becomes commonly used is the point where things go "free" and start being mainstream. Except with patent trolls obviously.

Anyway, there are more tooltips coming but I haven't written them fully yet. I'll also upload new screenshots if i figure out how.

how they than did the libx264 libary .. which is used by so many.

Software (libx264) is GPL as far as i know ... no patents. am i wrong?

I suggest to remove Maximum LTR Frames option temporary (set it 0), or we'll get Video Adapter select analog for years.
