Video playback / general responsiveness issues with chrome / chromium

Hello everyone,

I'm here because I've issues with responsiveness and video rendering in google chrome / chromium / (insert here a blink based browser). With my UX303UA (ultrabook with an i5 6500U and i520), I have very low FPS on youtube, issue that I don't have at all on firefox.

- I followed several pages of the wiki to try to resolve my isssue : … celeration … celeration
as well as this subject :

- I used this video for the record :

- I had the issue in every definition, in 60 fps or 30.

- Firstly I thought it could be an issue with VA-API installation :
I installed libva-intel-driver, libvdpau-va-gl, I tried to install intel-media-driver but 1 i didn't find any changes and 2 as said here … ing_VA-API it looks like it should replace libva-intel-driver, but if I remove the latter, vainfo give me the error "libva info: va_openDriver() returns -1
vaInitialize failed with error code -1 (unknown libva error),exit"

With this configuration I have :

[kuro@wildcat ~]$ vainfo 
vainfo: VA-API version: 1.3 (libva 2.3.0)
vainfo: Driver version: Intel i965 driver for Intel(R) Skylake - 2.2.0

      VAProfileH264High               :	VAEntrypointVLD

      VAProfileVC1Advanced            :	VAEntrypointVLD
      VAProfileNone                   :	VAEntrypointVideoProc
      VAProfileJPEGBaseline           :	VAEntrypointVLD
      VAProfileJPEGBaseline           :	VAEntrypointEncPicture

      VAProfileVP8Version0_3          :	VAEntrypointEncSlice

      VAProfileHEVCMain               :	VAEntrypointEncSlice

- Then, i thought it could come from chromium (the one with va-api support). I tried many flags but nothing worked :
Override software rendering list
GPU rasterization
Hardware-accelerated video (from the va-api patch)
Zero-copy rasterizer
Hardware-accelerated mjpeg decode for captured frame
I even added to the .desktop the flag --enable-native-gpu-memory-buffers from … celeration

Finally, the framerate is poor (but at least regular), chrome-ium say me acceleration is working (as below chrome://gpu) but obviously I don't know what to do more...

Re: Video playback / general responsiveness issues with chrome / chromium

It's not just you.  I couldn't get Chromium to play YouTube or Netflix properly - without dropping tons of frames - at all.  I know it's not a solution but what I did was simply switch to Firefox as my browser.  That works perfectly.

Re: Video playback / general responsiveness issues with chrome / chromium

Did you try --disable-gpu-driver-bug-workarounds? That fixed improved it for me.
