Recommended parameters for RTSP over bad network

[omer.tal]

Hey guys...
I'm trying to stream H264 with RTSP over a bad network. Are there any
recommended parameters which are better to avoid artifacts and frame loss in
the receiver's end?
Also, I'm trying to keep the latency as low as possible.

Thanks

H264 especially without incremental periodic frame refresh is probably not the best. Maybe need to consider transcoding to jpeg2000. Designed for varible bandwidth and is keyframeless. Using wavelets instead of dct means failure is more loss of cool resolution than block artifact

Hey there.

Unfortunately I'm using a limited bandwidth and must encode to video,
otherwise my bandwidth won't be sufficient.
I was just wondering how would it be best to set the parameters of the
rtppayloader or the encoder so that it will best fit the network?

NVIDIA has a summary on how to tune their encoders for different scenarios. One of them is low latency. You may extrapolate this configuration to your encoder:
