Re: Share/Record screen

[Dhanashree Kulkarni <ku...@gmail.com>]

Hello Maxim,

I have OM 3.2.1 on Linux 16.04. I am conducting video conference. And I
want to assess video quality so I am also capturing whole session in
wireshark.
Later I am using a python script to extract video data from captured PCAP
files. I want to compare these video files with original video which I
broadcasted to all clients. But after extraction, I am getting video
resolution to be 130*111. Is there any particular reason to get this
resolution everytime.

I have also tried changing webcam resolutions or trying to broadcast
different source video, but every time I get same resolution for output
video. I also checked it with other video conferencing tool which gave me
resolution of 320*240 for extracted video. I also checked codecs used by
ffmpeg. Is it happening because of ffmpeg configuration or red5 server?

Also, where transcoded input is going in OM?

Can you please give me some hint why this is so?
Thank you so much.

Re: Share/Record screen

Just have checked using our demo server:
https://om.alteametasoft.com/openmeetings

Web cam resolution by default is 120x90, you can change it in settings and
restart video, then resoultion will be better/worse

to get  rid of ffmpeg error you need to recompile ffmpeg from sources
