Question

Strange pause in recorded videos on Mac only

I'm using FMS 3.5 using a standard FMS instance as set up by Influxis to do straightforward recordings of FLV's (not F4V's) of user webcam video of only 10 seconds in length using netStream.publish().

Everything works fine on Windows, but on the Mac, on any browser, the recorded video will pause unpredictably for 2 to 10 or more seconds after a second or two.

It's not an issue with the streaming on playback, as I've downloaded the FLV's off the FMS server and they do in fact have the pauses in the videos, almost as if the video is malformed (in VLC, the playhead will stop for the duration of the pause, and then skip ahead once the real video content resumes).

Even more strangely, the information coming back from onMetadata gives me the length of the video including the mysterious pause/s.

Has anyone seen this type of behavior -- on the Mac only?

Any ideas or help on this would be greatly appreciated, as I'm pretty stumped.

    Hi Lee,

    Is it possible for you to share one or two FLVs that you have recorded using FMS 3.5?

    Thanks

    Mamata, thanks for the followup. I've just solved the problem.

    I believe what fixed it was setting the Microphone silenceLevel to 0, so that the audio data is always transmitted along with the video stream.

    Oh, also, I'm speculating that the problem was only showing itself on Macs in initial testing because of the microphone hardware on Macs were probably more uniform. Further testing on the PC ended up also revealing the same freezing bugs, just not as often...
