We have a separate flash media encoder that we used with an older tricaster we purchased and every thing works. We recently purchased a TCXD40 and now I would like to stream to our wowza server as an mp4 just like we do with the FME. I cant find where you change this in the software. so when we stream now it is a flv file and will not play on IOS devices. When we stream live we can watch on all devices but after the stream is done the saved flv will not play on IOS devices.
