Hi Derek,
- Any idea why the filter is set up this way??
Actually, I don't know. Given the tools I had when I began to learn about creating videos and the good results I had back then, MP4 became my favorite video format. In the BM2E (Before Moodle 2 Era) using MP4 videos was almost a natural choice; as a matter of fact, Matt's excellent Media Player plugin was always one of the first plugins I set in a new installation. But then, everything changed in the M2E. I suppose I must have read about the reasons back then, though I don't remember the specifics; however, the end result was that MP4 was suddenly classified as legacy
- So, there is no immediate work around?
I just checked (Administration > Appearance > Media embedding) and noticed that there actually two filters for MP4, one under Available players and the other under Legacy media players. You could try and disable the latter.
Maybe with a plugin like:
https://moodle.org/plugins/view.php?plugin=mod_richmedia
I also checked the medialib.php script and in class core_media_player_qt one can see how video size is handled. As we know, hacking code is ugly.
Nowadays I'm not working with any institution and so I don't have to struggle with Moodle as I had to, but at its moment I felt that M 2.x was quite a step backward regarding how arduous it became to do many everyday tasks.
