I am looking to provide live broadcasting services with two audio feature (users can choose which one to listen to by pressing a button on player) for live broadcasts that are being translated to a different language.
Currently we provide live streaming services using FMLE, Vidblaster, Wirecast, FMS, Wowza, JW Player.
We have already tried putting a separate JW Player with 2nd audio stream after the original player (which has audio muted). However, this is not a solution, because of synchronization problems.
Therefore I am looking for a person who can either build this functionality on JW Player preferably or build it on a different player. One idea worth playing with is sending audio1 and audio2 in separate channels in stereo, and later turning one on and other off, however it is mandatory to have audio in both speakers.
The expected results are:
1. develop an idea, how to stream video stream, audio1 stream and audio2 stream only (no video stream twice) to save bandwidth
2. deal with synchronization issues that arise when delivering video+audio1(muted) and audio2 in separate flash players
3. keep in mind that at the end of the day i will need a recording of live stream in both languages
4. prepare appropriate flash player for this case preferably based on JW Player
Is I noted above, one idea is to deliver audio1 in left and audio2 in right stereo channel, letting user choose which one to listen to, however the sound must be present in both speakers
