Releasing nvstreammux request pad blocked when input an invalid rtsp url

[529683504]

let me check

[529683504]

it doesnt work. I comment the line: “gst_element_set_state” and add line:" state_return=GST_STATE_CHANGE_SUCCESS;"

and run with an invalid rtsp

it still blocked in releasing pad:

It works in my device:

Can you upload your demo code? Let me compare with mine.

[Fiona.Chen]

The attached file is based on the code you send previously. deepstream_test3_app.c (19.4 KB)

[529683504]

your change is wrong,because only comment the “gst_element_set_state” leads to the variant "state_return "still have the value : GST_STATE_CHANGE_FAILURE( its the default value for state_return beacause GST_STATE_CHANGE_FAILURE=0)

if check your log ,you can see the log:

so, the code about releasing pad is not runing(because it in the case GST_STATE_CHANGE_SUCCESS) during your program executing.
you need write this:

to ensure your program go to the case GST_STATE_CHANGE_SUCCESS.

We will investigate the root cause and solution and feedback to you when there is any progress.

[529683504]

okey, waiting for your response. ；）

[529683504]

any update?

[pompos2]

Any updates? This is a serious issue as @529683504 mentions in #29 and #30

[lemonsqueeze]

@Fiona.Chen It’s been 3 months and this issue is still unresolved, please give us some feedback of your progress so far!

although i turned to do works for trt model generating,but THIS issue is sitll blocking my project

[dat348pq]

I have the same issue. Any update??

[529683504]

any update for now?

[Kenny.M]

any update?

The bug is fixed with DeepStream 6.0 GA.
