Hey Ulrich - good to see you are co-author of this plugin. I have revisited the plugin and like what I see.
I tested it out using a mp4 video file only and the plugin seems to be working well on Firefox Version 20.0, Opera Version 12.14 (1738) & 12.15 (build 1748), Safari Version 5.1.9 (6534.59.8) & Chrome Version 26.0.1410.65 - running Mac OSX 10.6.8.
I did noticed some strange behaviour though (Chrome & Safari) - if I right click on the progress bar the play head moves to this point and then when I release mouse button, the playhead scrolls forward or backward when I move the mouse left or right! Is this normal? This only happens the first time and subsequent right clicks on the progress bar will move the playhead to that point but scrolling does not occur.
Also I noticed if I don't add a splash image, when the player loads on Firefox I can see the progress bar but no first frame image appears....
Load time is much slower than VideoJS wordpress plugin too.
I would like to be able to CSS my own skin for the player, is this available yet? If not, do you think this will be available in future updates?
Thanks for your efforts with this plugin - seems like we are getting close to a complete solution for self-hosted videos. Future development I would like to see is for the plugin to do its own transcoding so all you need to do is upload one video file and it generates the other types necessary for cross-browser compatibility. Flash fall-back must be ready to die..... ;)
