rtsp server dynamic pipeline
Locked
 
|
Hello,
I want to generate pipelines for rtsp streaming via rtsp server, recording and live preview of a camera source. There can only be 1 instance of the camera source. The live preview pipe should always run. The recording pipe should only be activated when needed. As far as I know, the rtsp server only runs a pipe when a client is connected.
camerasrc
I
tee - vp8enc - matroskamux - filesink
I
tee - h264enc - rtph264pay
I
displaysink
How can I combine the rtsp server with the dynamic pipelines? I also want to change properties of the pipelines during runtime (bitrate,....). I already had a look at the interpipes from ridge run. But I had some problems with them and now try to use a low level approach.
Thanks in advance
Marc

Hi, In answer to your first question, take a look at the test_appsrc example in the examples subdirectory. That is how I solved a similar
problem. Gruesse Von: gstreamer-devel <[hidden email]>

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 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 shouldn't delete it when client disconnects?

As the server manages the pipeline state, you have no choices but to split in order to ensure the preview/recording keeps running while there is no clients.

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 -----Ursprüngliche Nachricht----- Von: gstreamer-devel <[hidden email]> Im Auftrag von Marca Gesendet: Mittwoch, 18.
