Encountered a NS_ERROR_DOM_MEDIA_FATAL_ERR in the MediaDecoderStateMachineBase.cpp process while accessing multiple pdf files.
Opened a directory of pdfs from the command line using ```firefox * &``` and went on with my work. Checked the terminal to see these error messages: ``` [Child 19416, MediaDecoderStateMachine #1] WARNING: Decoder=7f6e75431700 Decode error: NS_ERROR_DOM_MEDIA_FATAL_ERR (0x806e0005): file /builddir/build/BUILD/firefox-125.0.2/dom/media/MediaDecoderStateMachineBase.cpp:167 [Child 19416, MediaDecoderStateMachine #1] WARNING: Decoder=7f6e79a87a00 Decode error: NS_ERROR_DOM_MEDIA_FATAL_ERR (0x806e0005): file /builddir/build/BUILD/firefox-125.0.2/dom/media/MediaDecoderStateMachineBase.cpp:167 [Child 19416, MediaDecoderStateMachine #1] WARNING: Decoder=7f6e84e52400 Decode error: NS_ERROR_DOM_MEDIA_FATAL_ERR (0x806e0005): file /builddir/build/BUILD/firefox-125.0.2/dom/media/MediaDecoderStateMachineBase.cpp:167 ``` I tried recreating this error by restarting the entire process and repeating everything, but to no avail. I'll try to recreate the error a few more times, however if I don't post a message it means I was unsuccessful.

I don't think that those errors are related to PDF files. As you can see by the filename MediaDecoderStateMachineBase.cpp, this is about decoding media (audio/video).
Make sure you have the latest FFmpeg and libavcodec packages installed.
You can check the Media section in "Help -> More Troubleshooting Information" (about:support) to see if errors are reported and codec support.
