Thread: Sudden stream drops

  1. #1

    Default Sudden stream drops

    Hi,

    In the stream monitor I implemented in the custom module, I'm measuring FPS and KF rate using the following IMediaStreamH264SEINotify (SEIListener) listener:
    IMediaStreamH264SEINotify seiListener = new SEIListener(this);
    stream.addVideoH264SEIListener(seiListener);

    Basically counting how many video frames I get per second and of these how often there is a KF.

    My rules being that if there are no video frames coming in for 3 consecutive seconds OR FPS<3 for 10 seconds the stream is dropped.

    It seems that this is happening way too often.
    Streams with decent and good FPS all of a sudden drop to 0 or no more video frames come in.

    Do you have any insight why this might be happening?

    Thanks,
    Jonathan

    Default

    Some more insight from my end:
    1. It seems that with flash which is using rtmp to broadcast it happens much more often (~30%)
    2. From iOS however which uses rtsp it happens much much less, and is probably correct behavior (~6%)

    Thanks,
    Jonathan
