1933040 - [VAAPI] "Unsupported modifier, resource creation failed." resurfaced with log spam

Status: UNCONFIRMED

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

Description

[trunksm.wrk]

Attachment: Logs - Firefox-v132-0-2.png with default log and "MOZ_LOG="PlatformDecoderModule:5 Dmabuf:1" log.

User Agent: Mozilla/5.0 (X11; Linux x86_64; rv:132.0) Gecko/20100101 Firefox/132.0

Steps to reproduce:

1. Open Mozilla Firefox (ver 127.0 - 132.0.2) with Intel VA-API.
2. Force h264 playback using enhanced-h264ify extension.
3. Go to YouTube and play any video with 720p or above.
4. Confirm HW video decode by checking with programs such as intel_gpu_top (provided by intel-gpu-tools on Arch Linux). Or,about:support` page on Firefox, but is not a live feed.

Actual results:

Video will still work with hardware decode as normal, but journal log (Linux) or CLI output logs are heavily spammed with "Unsupported modifier, resource creation failed."

Determined to affect v127.0 - v132.0.2. Tested 125.* and 126.* with no issues.
Screenshot provided with default log output and one launched with MOZ_LOG="PlatformDecoderModule:5 Dmabuf:1" flag.

Expected results:

Since HW video decoding is working as expected on the surface, there should be no log spam of an issue that is not clear what's wrong with nothing apparently breaking-- at least to what I can understand so far.

I'm also seeing this issue after participating in the ticket https://bugzilla.mozilla.org/show_bug.cgi?id=1921742.

My system:

Distro: EndeavourOS (ARCH)
Kernel: 6.11.9-zen1-1-zen arch: x86_64 bits: 64
Desktop: GNOME v: 47.2
Firefox 133.03 (native package).

When I play this video @ 1080p60 the error does not occur:

When I play this video @ 1080p60 (while firefox is launched from Terminal) I will see the listed errors:
https://www.youtube.com/live/6nCNlI_0-KU?si=iEOlysHTyz5c8KRi

The error messages are the terminal filling with the error message:

Unsupported modifier, resource creation failed.

I've attached the support log for your reference.
