[FFmpeg-user] HTML5 live streaming

[Ricardo Kleemann]

Hi Guys,

Some additional info if someone can help... I'm actually able to play my
m3u8 stream directly using VLC... but in HTML5 video tag it is not working.
The iPad says that it cannot decode.

I must have something in the ts files that doesn't work for iPad, while it
still works for VLC

Any ideas on how to troubleshoot?

thanks
Ricardo
