Smart Record Example Details

Hello,

I am curious about how NvDsSRStop() works for SmartRecording feature. Can you please share some high level hints about it’s internal workings?

For example, the record bin at the end of the pipeline in the sample deepstream_test_sr_app.c seems to be “GstQueue name=cache_que0 | GstTee name=recordbin_tee0 | splitmuxsink”. What happens internally when NvDsSRStop() is called? Does cache_que0 get flushed? Are all newley recieved frames simply dropped internally via probe call? Any other speciall processing whens stopping/starting up again?

Thank you

NvDsSRStop() just send EOS event to finish the recording.

Does SmartRecording feature internally use GstSplitMuxSink? If not, any reasons why not to use the existing plugin?

Thank you

No. smart recording just want to provide API for our customers to control start/stop recording at any time. You can use gstsplitmuxsink if you think it meet your requirement.
