The RTSP URL cannot be reconnected after disconnection.

[Pi-Boss]

I try to enter the command

./video-viewer --input-decoder=v4l2 --input-loop=-1 rtsp://admin:123456@192.168.3.22:554/h264/ch1/main/av_stream rtsp://@:8566/test --no-display

I disconnected the camera from the network and then reconnected it, but the app cannot establish a connection to RTSP and keeps printing [gstreamer] gstDecoder::Capture() -- a timeout occurred waiting for the next image buffer in a loop.To reconnect to RTSP, I have to restart the app after exiting,the option ‘–input-loop’ seems to be invalid for RTSP I want to automatically retry connecting to RTSP after disconnection.Can you tell me how to achieve this? I’m looking forward to your reply, this feature is very important to me @dusty-nv

@Pi-Boss I think after a certain number of timeouts are detected, the easiest way would be to just recreate the videoSource interface. I recently added a recent status argument to videoSource::Capture() which allows you to determine when a timeout occurred:

https://github.com/dusty-nv/jetson-utils/blob/363148fb3558ae58c1b9b21ee2446de2de3355ae/video/videoSource.h#L240

(the Python videoSource.Capture() will return None on a timeout)

[Pi-Boss]

I found that frequently calling videoSource::Create(inputOpt) for a non-existent camera can lead to memory leaks. Although it returns nullptr, the 'dec' object is not released. In addition, the 'discover()' function in 'dec->init()' can also cause memory leaks. Of course, all of these issues only occur when the camera's RTSP connection cannot be established. @dusty-nv

[Pi-Boss]

If I simultaneously input 16 channels of RTSP video streams (H264 1920x1080) into Jetson NX and convert them into RTSP Server (H265 1920x1080), will it occupy all my GPU resources? I found that this will severely affect the model inference process of TensorRT inside the device.

[dusty-nv]

@Pi-Boss for that many simultaneous streams, you should look at DeepStream - it has higher performance

I will make a note to look into the memory leaks, thanks.

[Pi-Boss]

You're welcome, the jetson-utils open-source library is very useful, and I look forward to your continuous updates. @dusty-nv
