}The index seems not exceeding the size. but the frame is freed unexpectedly?

After trying a while, I get that the failure also accures without stun server setting, but the frequency is much lower.

Segmentation fault seems caused on StopStreaming which releases buffers, it is unrelated to the timeout.
StopStreaming must be called after ensuring that the frame is no longer accessed.
