Assuming you're successful with your approach have you thought about what you're going to display to user until you get back all requested data. That's not how things are normally working - very likely you have less or more significant data buffering going at your video decoder. Instead, you should be rather thinking about improving a decoding resiliency e.g. just by repeating non-corrupted/missing data or by using some more advanced tools present in H.264 - if that is your format.

I believe the breakage to happen when a keyframe goes missing, or when a packet is corrupted or missing. I would like to detect when this happens, in order to send an out-of-band message to the streaming server and force it to send another keyframe when one is lost. Could anyone give me any hint about how / where I could retrieve this information?
