Hi

When I browse to https://earthobservatory.nasa.gov/images/154162/clouds-hover-over-the-alaska-peninsula, I can play the shown video once.

When the video is about to start the 2nd time though, the log from the web developer tool says (see screenshot): ``` Media resource https://eoimages.gsfc.nasa.gov/images/imagerecords/154000/154162/ak_cloudwave_vir_20250407_anim.mp4 could not be decoded. clouds-hover-over-the-alaska-peninsula All candidate resources failed to load. Media load paused. clouds-hover-over-the-alaska-peninsula Media resource https://eoimages.gsfc.nasa.gov/images/imagerecords/154000/154162/ak_cloudwave_vir_20250407_anim.mp4 could not be decoded, error: Error Code: NS_ERROR_DOM_MEDIA_FATAL_ERR (0x806e0005) Details: virtual RefPtr<MediaDataDecoder::DecodePromise> mozilla::GMPVideoDecoder::Decode(MediaRawData *): mGMP not initialized ``` and the video shows the warning "No video with supported format and MIME type found.", although the video was successfully played the 1st time.

Note that the first four warnings in the screenshot already appear when loading the page, i.e. before playing the video the 1st time.

The same happens when all installed firefox plugins are disabled.

I am using firefox 137.0.1 (64 bit) on arch linux.

Thanks for help, Chris
