1318541 - Re-add media stats overlay

Status: NEW

(Core :: Audio/Video: Playback, defect, P3)

Description

[Jean-Yves Avenard [:jya]]

In bug 1270853:
"I've heard reports from some of the developers who work on video playback for Gecko, as well as Dolske, that the statistics offered through the controls are unreliable/don't offer enough data to make them useful.

I would have much preferred, that the data provided be made reliable (and they are really), and simply add more data to make it useful.

Right now, I certainly wish it was there...

I don't see how this ticket can block bug #1270853 . I think it makes more sense to change it to block bug #1271768 instead.

Because for whatever reason, the way dependencies are set: a regression "blocks" the bug that caused it.

Comment 3

[Matt Woodrow (:mattwoodrow)]

Can we please include the hardware acceleration status (the result of IsHardwareAcceleration, plus the debug message returned) in this overlay?

We do this for a dummy decoder in about:support, but that's partially broken by the gpu process (and isn't trivially fixed), and also is a lot more meaningful for a 'real' decoder.

Maybe this can be added into the media developer tools.

[Jean-Yves Avenard [:jya]]

going to add this now... I need it again to check how we drop frames...

Related bug 1724916.

I really want this feature implemented.

Would be great if Firefox showed:

1. Resolution and framerate, e.g. 1920x1080@30fps
2. Codec, e.g. VP9
3. Whether HW acceleration is enabled
4. Audio Codec and bitrate
5. Aspect ratio
6. Pixel format

Attachment: info94.webp

E.g. similar to what MPV shows.

Comment 9

It would be great to see this feature implemented.

Today my laptop has suddenly started using twice as much energy for playing VP9 videos and I realized I'd upgraded Mesa but forgot to install a MESA package which enables HW video decoding.

Please do.
