Hardware decoding not working after updating to Ubuntu 20.04 (iHD driver) #83

There is no build in my PPA for 20.04 yet. |
|
Thanks for telling that. Please let me know if there's a way to run it currently or if it's going to come soon. |

I confirm - hardware decoding does not work on Ubuntu 20.04. `$ chromium-browser $ vainfo |
|
Is this with Chromium |
|
yes |
|
I can confirm, with the new build (which starts up now as expected) VA-API hw decoding doesn't work anymore on my Intel HD 3000. Disabling hw video decoding makes video playback working again. libva info: VA-API version 1.7.0 |

Ok, I think I figured out the difference in error conditions. Both I and @Sraw had The first error might be easy to work around in Chromium's code, the second error might take some time. |

Another update on this, the iHD driver seems to only allow NV12 color format, but some other color format appears to be being passed in (I420, I'm guessing, but can't confirm). Here's a snippet of the driver trace logs, interleaved with Chromium logs: Note the |

For reference, to get these logs, the (Some of the entries can probably be removed, though.) Start Chromium from the console, and see the driver trace logs be printed onto the console. |

Beta PPA version (84.0.4147.56) seems to be working. Just FYI. |
|
Dev has been updated to 86.0.4214.2, Beta is being updated to 85.0.4183.49. |

After the update, GPU decoding is not working with the beta PPA version (85.0.4183.49). |

I had the same issue and output as @mamarley. Uninstalling intel-media-va-driver solved the problem as @saiarcot895 suggested. Thanks a lot and keep up the good work! |

HI ! I think my install could work but i can't get chromium to use the right driver Below my standard vainfo output But when starting chromium it try to use the i965 driver see : I tried If someone could explain to me why ? And how i can force it to use iHD ? Thanks for your work on this (If not here where could i post this question?) #EDIT : I changed the file : with this in I take any insight ? cause for now, i have to reboot to W10 to watch video online without draining my battery :/ |

Chromium itself is blocking the iHD driver because of errors in the driver itself. I can remove it, but then you will see those errors if that driver is used. This means that the i965 driver must be used on Intel systems. |

I have been using Pop OS which is based on Ubuntu and just updated to latest version ie 20.04.
Now I am not noticing hardware decoding working anymore - earlier
intel_gpu_topused to show decoding activity.So I installed chromium from correct source again, checked the hardware accelerated video decode flag, the h264 enabling plugin and ran again. However, I am still not seeing video decoding activity ( The tool earlier mentioned 'Decode' flag but now it seems like the third flag is the relevant one ). Is the functionality intact in the latest Ubuntu update?
