MrMC

I deleted MrMC and set it up from scratch just to make sure.

I'd post a log but it seems gist won't let me without an account now.

Even though it is not as smooth when skipping forward/back and video may glitch doing this, I find it gives superior PQ for the most part. Most video with low-light scenes look very bad with Video Toolbox - lots of washed-out looking blacks/grays, things look dithered and/or pastel-like (does anyone else notice this?)

With new 3.5.1 I notice that I have very bad performance issues with stuttering and jerky playback using the new Plex add-on. Plex playback in native MrMC works fine. I discover that setting it back to use Video Toolbox makes it play much better with Plex add-on. Presuming that most people probably leave default to play using Video Toolbox they may not notice this. Can anyone else try and verify if they also get very back playback when using only AV Foundation? It seems to do this pretty much every time when skipping through video and pretty much all the time with HEVC.

The default settings are there for a reason, video content in h264 format can contain a lot of bad encoding with non-spec profiles/levels. h265 is less problematic. So VideoToolBox has much more robust error handling than AVFoundation.

Use mediainfo to quality problem videos under VideToolBox and samples go a long way for us to understand issues. As mentioned elsewhere, setting brightness to 46 percent yields perfect match to test/calibration video content. Even so, if the test/calibration sources pass or are close, the content should look as it was intended to look.

One issue we just discovered is that some hevc encoded videos are posing as HDR while in-fact, they are SDR. Encoder abuse we call it Looking into fixing this.

Sorry, I am a little confused. I’ve tried using Video Toolbox and noticed the washed out appearance also. The solution to that is to adjust the MrMC brightness control to 46?
