RTSP Server stop problem (AUD-5224) #1157

Environment

Problem Description

Hi, I'm using the RTSP example to stream video via RTSP server. I removed the CLI functionalities and I'm trying to stop the RTSP server via the rtsp_service_stop() function provided by the example and I get a "Guru Meditation Error: Core 0 panic'ed (InstrFetchProhibited)". I tried to call the function when receiving the RTSP_STATE_TEARDOWN event (in the switch case) and i also tried to trigger the function using input keys right after starting the server. I get different errors, you can see it below.

Am I choosing the wrong place to call the function? If so, what would be the best point to call it? Thanks in advance.

Hi @matz-9 ,

In the two situations you mentioned, we should add error processing.

The purpose of RTSP_STATE_TEARDOWN is to tell the user that remote client has disconnected and needs to destroy media resources. You can stop rtsp server at any time after this event, but not within this event, because this will block server tasks.

But there should be no problem pressing the button to stop the service. I need to check further.

Thanks.

Hi @ahhfzhang,

Thank you for your answer, please let me know if you have any news. What I'm trying to do is start both the camera and the MicroSD (Korvo 2), to save a frame in the SD, but they seem to be incompatible, so I thought I'd stop RTSP, destroy the peripherals and start the MicroSD.

Thanks.

Hi @ahhfzhang, any update on this? (pressing the button to stop the RTSP service)

Thanks.
