Repeatedly Creating RtspServerStream and Encountering 'Create VideoEncoder failed' Issue

[Mett-Barr]

Hello, my current requirement involves creating independently managed RtspServerStreams in different scenarios. Initially, the first eight creations and usages of the streams went without any issues. However, issues start occurring from the ninth creation onwards. Each time I use it after that, and especially when calling prepareVideo(), I encounter the following problems:

I've attempted to call stopPreview() and stopRecord() after closing the previous RtspServerStream (as calling stopStream() and release() leads to crashes currently). However, I still face the 'Create VideoEncoder failed' issue. Could there be a step that I'm missing? Thank you for your help.

Hello,

Are you calling release method when RtspServerStream is not needed anymore?

rtspServerStream.release()
