Thanks Maxim. The recording parameters sent to the
"setConnectionAsSharingClient" are listed as:
screenWidth=1440, screenHeight=816, screenX=0, screenY=0
The parameters listed in ScreenDimensions.java are:
public static ScreenQuality quality = ScreenQuality.High;
public static int FPS = 10;
A screen sharing from a PC of a small movie originated up to 17 Megabits of
traffic into the Red5 server (measured by a server performance tool)
The recorded video of the screen sharing has the following format:
Input #0, flv, from 'testfile.flv':
Metadata:
server : Red5
canSeekToEnd : true
recordeddate : 2018-08-28T18:54:48.512Z
noaudiocodec : 0
Duration: 00:01:53.50, start: 0.000000, bitrate: 29861 kb/s
Stream #0:0: Video: flashsv, bgr24, 1440x816, 10 fps, 10 tbr, 1k tbn,
1k tbc
Note: In Windows task manager we saw that Ethernet traffic being sent from
PC was like 20, 30, 40 Megabits, whereas the traffic being received in the
PC was 3, 5, 7. 16 when the movie was transmitted to Red5.
Thanks again for any help to understand and find a solution to this issue.
Regards,
Sonia
