DS Version :- 6.2, Hardware :- Jetson
I have a pipeline that looks like this
appsrc -> jpegparser -> nvv4l2decoder -> streammux -> pgie -> tracker -> sink
need-data callback of
appsrc, when it gets invoked, a function
read_data is called.
On the other hand, I have a program ( say camera_client) that taken images from cameras and puts them in a redis queue.
when I interface multiple cameras with camera_client, the way it this program is written is, it will take images from n cameras and put them into a redis queue…
when the read_data function reads images from this redis queue, converts them into
GstBuffer and pushes them in the pipeline.
the problem is, streammux is assuming that all the images are coming from a single source ( as it should, no complaints). I want it to handle each stream context differently.
can I do this ? → If I attach stream_id as custom_meta to the buffer before I push it in the pipeline and then at sink pad of streammux, I manually update/modify the
NvDsFrameMeta->source_id, will this solve my problem? will tracker have different context for each stream if I do this ?
or is there any other way ?
