AW: AW: rtsp server dynamic pipeline

[Thornton, Keith]

Hi,
In answer to the first part, it is possible to re-use the memory in order to avoid a memcpy while assigning a new GstBuffer.
Use gst_buffer_new_wrapped_full and remember to set a free memory function
regards

Hi,

thanks alot for your answer. I didn't know the appsrc exampe yet. So I have to exchange buffers manually between appsink and appsrc. I work on embedded side with jetson nano board. I don't know if buffer exchange of NVMM buffers works this way?! Otherwise a copy to userspace would be necessary which kills performance.

Is there no way to generate a pipeline which consists of the live preview and the streaming part and which always exists and runs? This pipeline should be given to the rtsp server who doesn't delete it when client disconnects?

Greetings

Marc
