[Live-devel] announcing rtsp stream - more info

[nishesh chouhan]

Hi ,

following is the bt from brakepoint in gdb.. when we receive DESCRIBE from
client.
I put brakepoint in doGetNextFrame...in normal scenario(working case) this
hits only when we receive PLAY command....but here its getting hit
when we receive DESCIBE and the reponse to DESCRIBE sent is either "400 bad
request" or "404 file not found"....what is the exact problem here...its
really getting hard to debug
