Thread: Live & mp4 recording?

  1. #1

    Default Live & mp4 recording?

    Live stream of 5 or so streams, and I'd also like to track them to standard mp4 in the same application. Can't quite seem to find an answer if that's possible. I have the DVR addon, but that can't produce a simple mp4. live-record addon requires it started for each one every time (plus it didn't work when I tried it, that's besides the point at the moment) and I'd rather have all streams automatically started when the live stream beings. Are either of those conclusions wrong? Is there a way to do so?

    To record all live streams you make the Application.xml /StreamType "live-record"

    There is a LiveStreamRecord addon, but "live-record" is just a StreamType.

    Ah. I see a little bit of docs in the PDF guide. So to get the mp4:

    "You can control the container format used (FLV or MP4) by specifying a stream name prefix in the encoder."

    I tried setting the stream name to "livestream-1.mp4", and got a filename livestream-1.mp4.flv Is there an xml preference to force an mp4?

    If you change the stream name in the encoder to "mp4:livestream-1", then Wowza will record to mp4 container, to file named livestream-1.mp4

    The video must be h.264 and the audio must be aac or mp3

    I'm using the mp4: prefix and wowza is recording an mp4 file but it will not open in QT. I get the error, "An invalid public movie atom was found in the movie." I'm pretty sure it's recording H264/AAC because when I record an flv and open in VLC, and look at codec details, that's what it shows.

    thanks,
    Dave

    Dave,

    Are you able to play it back in Flash? Test with Wowza /examples/SimpleVideoStreaming/client/simplevideostreaming.xml

    The mp4 will load into the browser and show the controls but will not play.

    Try it without the mp4: prefix

    I think QT player shows encoding details. It might be vp6 or spark video.
