I have seen a issue with video quality while checking response of mediastreamer for packet loss. I am using H264 codec. (openH264).

I am having two medisstreamer application that streams H264-packets to each other. Whenever, I introduce pakcet loss, video quality degrades. Please note that I am not inducing packet loss more than 2%. I do see "PLI requests" floating around. The VOIP application such as Skype freezes on packet loss and continues as soon as it gets valid packet. I have seen an option "--freeze-on-error". However, it doesn't help.
The command that I am using:
mediastream --local 6788 --remote --payload 'video/H264/90000' --bitrate 2560000 --width 800 --height 600 --freeze-on-error

Am I missing anything? Would you please help me to fix the problem?
