QSV not detected by Handbrake but working and detected in other apps

Post by jpw »

Description of problem or question:

Hi, I'm trying to get Handbrake to use the J4115 QSV hardware for hardware transcoding on Ubuntu 18.04. I've tried Ubuntu 20.04 with the same results. I have QSV working to the extent that Plex is able to detect and use the QSV hardware. vainfo also reports the following:

I've tried building Handbrake from source, using prebuilt binaries, and using the Handbrake flatpak. All report

Code: Select all

Intel Quick Sync Video support: no
Steps to reproduce the problem (If Applicable):

This has been reproducible in all configurations that I've tried.


HandBrake version (e.g., 1.0.0):

1.3.3 (2020061500)


Operating system and version (e.g., Ubuntu 16.04 LTS, macOS 10.13 High Sierra, Windows 10 Creators Update):

I've tried Ubuntu 18.04, Ubuntu 20.04. Both running within a VM. I'm also able to reproduce this behavior on the Proxmox host (and QSV works within Plex within the VM), and as a result I don't think that this is a VM issue.


HandBrake Activity Log ***required*** (see How-to get an activity log)

I terminated the transcode after a few seconds since it was clear that QSV wasn't enabled.

Code: Select all

There's also a driver flatpak needed for QSV, as I recall, "QuickSync Plugin Download (64bit)" on the download page. Did you install that when the flatpak version?

Thanks for the quick response. I overlooked the QSV flatpak which definitely moved the needle and now I can see that QSV is enabled. Unfortunately, encoding fails with the following error:

Code: Select all

[01:55:59] qsv_enc_init: using 'hardware (2) via VAAPI' implementation, API: 1.32
Error code -21, hb_qsv_wait_on_sync     605
ERROR: encqsv: MFXVideoENCODE_EncodeFrameAsync failed (-21)
This doesn't seem to be a fully deterministic error though, as I also received the following on another run using the same media:

Code: Select all

[01:47:53] qsv_enc_init: using 'hardware (2) via VAAPI' implementation, API: 1.32
ERROR: QSV: not enough to have 10 surface(s) allocated
ERROR: encqsv: hb_qsv_get_free_surface failed
Is there any recommended debugging that I can do from here?
