Question

FMS closes connection when publishing 1600x1200 screen

I am publishing screen data to FMS 3.5.3 using ffmpeg  with flv.  Everything is fine with 1024 x 768.  When I try to publish 1600 x 1200, the connection closes and I get an entry in core.00.log:

1458 (e)2631029      Bad network data;  terminating conection.

Is there a configuration limit I may be hitting?

Thanks.

    Hi,

    I tried the same using Flash Media Live Encoder and published screen data setting the input size greater than 1600 x 1200 too. I didn't see any issue on FMS. I didn't get a chance to check with  ffmpeg. But do you see that happening everytime you set the size as 1600 x 1200 consistently?

    Thanks

    Hi Mamata,

    Thanks for the response. Yes, I consistently see the FMS close the connection when I try to stream 1600 x 1200. 1024 x 768 works fine as does 1200 x 800. 1280 x 1024 works for a while then stops.

    Here is my ffmpeg output:
