Unable to display RTSP stream #3

Hi sahil,

Appreciate the work you have put in to read a rtsp stream using gstreamer. I am trying to read from a Mambo Parrot drone a rtsp stream as numpy arrays. I have ran your instructions and code accordingly. The window pops up but after 1-2 frames it just stops and breaks.

The following error was thrown up : Error received from element m_rtspsrc: gst-resource-error-quark: Could not read from resource. (9) Debugging information: gstrtspsrc.c(4662): gst_rtspsrc_loop_interleaved (): /GstPipeline:pipeline0/GstRTSPSrc:m_rtspsrc: Could not receive message. (Parse error)

This error also keeps popping up before the above error: Unexpected message received Unexpected message received

Hope you can point me in the right direction as to how to fix this. Thank you very much!

Hi @Kaynelua ,

Thanks for pointing it out. "Unexpected message received" may pop up sometimes because of network conditioning. To handle this i have updated the code to shutdown the stream if error exceeds the predefined allowed max error counts. This will give you a chance in main program to try to re-initialize the stream on stopbit untill you find stable connection again. Let me know if that helped you.

@Kaynelua Please let me know if this helped you?

Sure I will keep you updated once I tried it

Sorry for the late update i was really tied up with reports. Anyway, this didnt fix the problem, and i got the same exact error message. Running Gstreamer directly on command line worked for me :

gst-launch-1.0 rtspsrc location=rtsp://192.168.99.1/media/stream2 latency=10 ! decodebin ! autovideosink

But cant seem to make it work on python i have no idea why
