It seems that the problem "NS_ERROR_DOM_MEDIA_DEMUXER_ERR (0x806e000c)" has been spoken here https://github.com/w3c/media-source/issues/196

According to Mozilla guidelines, latest versions of Firefox should support MP4 video streams inside <video> elements when an external plugin (namely, gstreamer 1.0) is available

However, after installing gstreamer1 packages from SBo, the support is still not available, probably because the package was not build with support to the gstreamer libs. 

This can also be seen in the about:buildconfig page, as --enable-gstreamer1 is not listed in build-time options.

This is mp4v video, Firefox doesn't support this format, please use H264 or VP8/9.

Chrome doesn't play it either. 
Currently we don't have plans to support it.

There is a note in MDN that states:

Firefox supports MP4V-ES in 3GP containers only.

Here it sounds like we don't support it at all. Can you confirm?

This fell out of a user issue: https://github.com/mdn/content/pull/35442

PS Appreciate this is not the best way to ask questions, but I'm not sure of the "right" one.
