Many thanks to Sascha for the clarification and useful information. 1 ffmpeg could be used to create FLV video from a wide range of formats 2 FLEX, ming(PHP), openlaszlo (LZX compareable to FLEX) could be used to create swf on the fly. 3 AJAX/Flash front end.
>> there is also a java api for that i think.andy may u could make a >> containerclip thats able to handle your commands, I'm sorry, but what do you mean here by a java api? based on openlaszlo to handle commands to create swf on the fly? 4 It seems that Red5 is not suitable for our needs. How to delivery the FLV files? a normal file?
