rtsp to html5 video tag

[Carlos Rafael Giani]

A big blunder indeed. HTML5 video adds a lot of restrictions. The only 
two options I found to work are:

1) Demux the RTSP stream, re-mux it into fragmented MP4, send this over 
HTTP (using EOF encoding, that is: no keepalive, no content-length, 
"message" ends when the server closes the socket); may also require 
transcoding to make sure the right audio and video codecs are used, and 
can be tricky with one-to-many streaming

2) Similar to (1), but transmit using HLS or DASH instead - these may be 
more useful for one-to-many streaming (since chunks can be shared 
between connections), but they are considerably more complex, and can 
cause problems if the stream isn't always there (for example, if an HLS 
stream starts on-demand, when the first client connects, then in the 
beginning, there is no .m3u8 file present yet)

Without HTML5, it becomes considerably easier, yes. Although I prefer 
Matroska over MPEGTS.
