[Live-devel] how to detect frame loss

[satheesh Ramalingam]

Hi,

I remember we had similar discussion earlier regarding packet loss.
Search the archive for subject "[Live-devel] Buffering incoming data with openRTSP?"

The first byte in the payload has the payload type (I or P or Non-ref P or....).
In case of packet loss, keep dropping packets till you get next I frame. This logic has to be added as part of your application on top of live555 rtsp receiver.

Subject: [Live-devel] how to detect frame loss

Hello,
I'm doing this almost 2 weeks it is somewhat difficult to me..

My embedded board receive h.264 baseline stream from IP camera.
During the system overhead or temporary network disconnection,
P frame (or I frame) is lost,
and then screen display breaks until next I frame received.
So, I wanna detect (P) frame loss and skip P frames to next I frame.
Can this be done by live555? Or need some application side process?

To summarise

1.     How can I detect P frame loss?

2.     If above is possible, where should it be done to skip P frames? (Live555 or application)

Any advice will be welcomed.
