MacBook late 2008 with dual core 2.0ghz CPU cannot play correctly a h265 .mkv file of around 5000kbps bitrate. Frames are getting skipped and CPU is 100%.
Tested with 2.1.5 and 2.2.0 RC2.
To upload designs, you'll need to enable LFS and have an admin enable hashed storage. More information
Regrettably, this is the expected behavior. H265 is a lot more demanding than H264 and might be a bit too much for a 6.5 year old Mac. While we will make continous speed improvements to our decoding library, we can't make promisses if it becomes fast enough for your Mac one day.
You might be able to speed things up by playing with the "loop filter" setting in the "Codecs" section of VLC's preferences, but again, I'm not sure if this is enough.

That's what I thought initially. But then I started to search up a bit and read on forums that people were able to play h265 with quite underpowered mediacenter machines (800Mhz and alike) under Windows / Linux and so I thought it was some performance problem on the VLC for Mac OS X specific code.
The information I found was about h265 be quite CPU-demanding on encoding (which is perfectly fine) but not so much on decoding, so I thought my poor 2Ghz dual core CPU could handle it.
Indeed, the video I was watching had quite a big resolution (1080p) so I guess VLC was also struggling with downsampling as the screen got almost half of the resolution of the video file.

I tried to play a bit with hardware acceleration, post-processing filter quality, and also giving the VLC process more priority. All without any luck.
I will try the loop filter and let you know the results.
Thank you very much for the quick reply. Really appreciated.
Have a nice day.
