1243575 - Firefox fails to detect H.264 decoder

Status: RESOLVED DUPLICATE of bug 1210726

(Core :: Audio/Video: Playback, defect)

Description

[firefox]

Attachment: about:support page for details

User Agent: Mozilla/5.0 (X11; Linux x86_64; rv:44.0) Gecko/20100101 Firefox/44.0
Build ID: 20160126104524

Steps to reproduce:

Firefox 44.0 now enables H.264 decoding by default if it detects a system decoder. However, it fails to do so on Linux, even tough hardware and drivers are properly identified as:
Intel Open Source Technology Center -- Mesa DRI Intel(R) HD Graphics 520 (Skylake GT2)

ffmpeg, libvpx, libx264, libvdpau, libva, libva-intel-driver, etc are installed and configured.

vdpauinfo and vainfo confirm proper configuration with driver /usr/lib/dri/i965_drv_video.so


Actual results:

about:support lists - Supports Hardware H264 Decoding -> No;


Expected results:

about:support lists - Supports Hardware H264 Decoding -> Yes;

[Jean-Yves Avenard [:jya]]

about:support shows weither this system supports *hardware* h264 decoding in Firefox.
The answer is no, it doesn't.

On Linux, h264 decoding is software only

VAAPI and VDPAU support are tracked in bug 1210727 and bug 1210729

We do not have hardware decoding support for linux at this stage.
