Tested only on latest chrome, some issues in FF/Edge, untested in other browsers (safari, all mobile)
Can only play videos supported by the web browser (mp4/ogg, flv/avi). This also makes it depend on the browser to use CPU/GPU for rendering videos. Firefox (at the time of testing) was extremely slow with 10+ videos.
Depends on Web browser and its File API, can't read/write to disk directly (for example creating playlists, reading entire directories)
