This is a meta issue for all mediaplugin and resource media embedding problems:
1/ finish conversion to flowplayer - outdated version, incorrectly imported, hacky integration, old players have license issues
2/ fix media sizes and resizing from url - there were incorrect CSS sizes and size hints from URL did not work
3/ more iOS compatibility - mp3 and youtube especially
4/ remove old eolas workaround and media players - not necessary in current browsers
5/ move image embedding to filter_urltolink - this new image support in mediafilter was intended to allow entering of image urls in FORMAT_MOODLE, unfortunately it was eating all image links
6/ improve regex matching
7/ switch hack player colors to use real CSS - OUTPUT must not be used from filters due to caching issues
8/ sync embedding code in mediafilter and resources
