1760514 - "NS_ERROR_DOM_MEDIA_FATAL_ERR" and "amdgpu.ids: Permission denied" don't allow me to play videos

Status: RESOLVED DUPLICATE of bug 1751363

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

Description

[a.geno]

User Agent: Mozilla/5.0 (X11; Linux x86_64; rv:98.0) Gecko/20100101 Firefox/98.0

Steps to reproduce:

If I open Firefox and go to youtube for example

Actual results:

The video does not play.
Sometimes if I wait it plays.
If I open firefox via commandline I receive these errors:

libva info: VA-API version 1.13.0
libva info: User environment variable requested driver 'radeonsi'
libva info: Trying to open /usr/lib/dri/radeonsi_drv_video.so
libva info: Found init function __vaDriverInit_1_13
/usr/share/libdrm/amdgpu.ids: Permission denied
[Child 20635, MediaDecoderStateMachine #1] WARNING: Decoder=7ff6783d9a00 Decode error: NS_ERROR_DOM_MEDIA_FATAL_ERR (0x806e0005) - auto mozilla::MediaChangeMonitor::CreateDecoderAndInit(mozilla::MediaRawData *)::(anonymous class)::operator()()::(anonymous class)::operator()(const mozilla::MediaResult &) const: Unable to initialize decoder: file /build/firefox/src/firefox-98.0.1/dom/media/MediaDecoderStateMachine.cpp:3568

If I change media.rdd-process.enabled from true to false, the video plays and I don't get any errors. What does this media.rdd-process.enabled do? What changes if I set it to false? Is it a bad thing?

Expected results:

It should play.
