1883746 - Talos logs don't report codec support info

Status: NEW

(Core :: Audio/Video, defect)

Description

I was trying to get a sense of what the mac minis we use for Talos runs support in terms of hardware video decoding. The tests all run an about:support dump before shutdown [1]. You can find this in the logs by searching for __metrics string. On windows the codec support info in these dumps is reported, but on mac the output is blank [2]. This despite Intel claiming support is available [3]. I am looking at the webcodecs tests (like 'offscreencanvas_webcodecs_worker_2d_vp9') so I'm pretty sure the about support info should be populated.

[2] "codecSupportInfo": ""
[3] https://www.intel.com/content/www/us/en/developer/articles/technical/encode-and-decode-capabilities-for-7th-generation-intel-core-processors-and-newer.html

Ashley, any ideas what's going on here?

:az determined that Talos launches a new instance to get the about:support text after a test runs, which blows away any data we would have had after running a media test.
