gstreamer rtsp timeout #31

Open kennycoder opened 4 years ago

kennycoder commented 4 years ago

I'm trying to send video via rtsp through gstreamer but for some reason it's timing out. VLC and ffmpeg work fine. I worked with gstreamer before and it still works fine with other cameras that support RTSP. After a bit of debugging, the handshake is fine: OPTIONS and DESCRIBE commands work perfectly fine. When PLAY command comes from gstreamer, micro-rtsp responds correctly but then no data is transmitted and after pre-defined timeout gstreamer throws an error.

After adding some debugging linkes, this is the output from Micro-RTSP server:

I know this is not gstreamer support but maybe you have any ideas. Also after accessing rtsp stream twice in a row there is a kernel panic on esp32-cam right after PLAY command is issued:

This is a long shot since this issue is already 2 years old, but could you ever get this to work? I'm facing a similar issue right now and I need to get this to work for my thesis!
