Bug#923080: chromium: libva error: va_getDriverName() failed with unknown libva error,driver_name=(null)

[Paul Menzel]

Package: chromium
Version: 72.0.3626.109-1
Severity: wishlist

Dear Debian folks,


Decoding videos on the GPU using VA-API does not seem to work after bugs
reports #856255 [1] and #919762 [2] were fixed.

The messages below are shown during start.

```
$ chromium
libva error: va_getDriverName() failed with unknown libva
error,driver_name=(null)
[28239:28239:0223/215051.751645:ERROR:vaapi_wrapper.cc(324)]
vaInitialize failed: unknown libva error
[28239:28239:0223/215051.795078:ERROR:sandbox_linux.cc(364)]
InitializeSandbox() called with multiple threads in process gpu-process.
libpng warning: iCCP: known incorrect sRGB profile
libpng warning: iCCP: known incorrect sRGB profile
libpng warning: iCCP: known incorrect sRGB profile
```

VA-API is installed properly though.

```
$ vainfo
libva info: VA-API version 1.4.0
libva info: va_getDriverName() returns 0
libva info: Trying to open /usr/lib/x86_64-linux-gnu/dri/i965_drv_video.so
libva info: Found init function __vaDriverInit_1_4
libva info: va_openDriver() returns 0
vainfo: VA-API version: 1.4 (libva 2.4.0)
vainfo: Driver version: Intel i965 driver for Intel(R) Broadwell - 2.3.0
vainfo: Supported profile and entrypoints
VAProfileMPEG2Simple : VAEntrypointVLD
VAProfileMPEG2Simple : VAEntrypointEncSlice

VAProfileH264MultiviewHigh : VAEntrypointVLD
VAProfileH264StereoHigh : VAEntrypointVLD

VAProfileVC1Main : VAEntrypointVLD
VAProfileVC1Advanced : VAEntrypointVLD
VAProfileJPEGBaseline : VAEntrypointVLD
VAProfileVP8Version0_3 : VAEntrypointVLD
```

So it looks like, some piece is still missing for working VA-API support.


Kind regards,

Paul

Dear Debian folks,

Looking more into this, the media mplayer *mpv* has the same problem,
and I found upstream bug report/issue [3].

There are patches, but the merge/pull request [4] was closed, as the
author is not working on it anymore. The user *jnettlet* successfully
tested the commits, and offered to rebase the commits.

Kind regards,

Paul
