How to use Gstreamer to ingress live stream on Azure Media Services using RTMP in a long run?

Matin Lotfaliei 5

With some inspiration from another post, I can successfully have a live stream on Azure Media Services Basic Pass-through Live Event using Gstreamer and RTMP.

However, it won't stay for long. I want to have the stream working 24/7, but after some hours, the preview and the egress output get more and more buffering/loading with many browser console 404 errors.

I suspect that it is because I restart the stream once every 6 hours? How can I fix that?

Here is my Gstreamer command:

gst-launch-1.0 v4l2src device=/dev/video0 ! video/x-raw, width=640, height=480, format=BGR \                                                                                                 
    ! vspmfilter dmabuf-use=true ! video/x-raw, format=NV12 \                                                                                                                                
    ! omxh264enc control-rate=2 target-bitrate=10485760 \                                                                                                                                    
    ! video/x-h264,profile=\(string\)high,level=\(string\)4.2 \                                                                                                                              
    ! h264parse config-interval=-1 \                                                                                                                                                         
    ! mux. audiotestsrc is-live=true wave=silence ! audio/x-raw,rate=48000 ! faac bitrate=96000 ! aacparse ! audio/mpeg, mpegversion=4! mux. flvmux streamable=true name=mux \               
    ! rtmpsink location="${dest} live=1 flashver=FMLE/3.0(compatibble;FMSc/1.0)"

@Matin Lotfaliei It seems like the issue you are facing is due to the fact that you are restarting the stream every 6 hours. This can cause buffering and loading issues, as well as 404 errors in the browser console. To fix this, you can try using a persistent connection instead of restarting the stream every 6 hours. One way to achieve this is by using the rtmp plugin in GStreamer with the timeout parameter set to a high value. This will keep the connection alive for a longer period of time, preventing buffering and loading issues. Here is an example command:

gst-launch-1.0 v4l2src device=/dev/video0 ! video/x-raw, width=640, height=480, format=BGR \                                                                                                 
    ! vspmfilter dmabuf-use=true ! video/x-raw, format=NV12 \                                                                                                                                
    ! omxh264enc control-rate=2 target-bitrate=10485760 \                                                                                                                                    
    ! video/x-h264,profile=\(string\)high,level=\(string\)4.2 \                                                                                                                              
    ! h264parse config-interval=-1 \                                                                                                                                                         
    ! mux. audiotestsrc is-live=true wave=silence ! audio/x-raw,rate=48000 ! faac bitrate=96000 ! aacparse ! audio/mpeg, mpegversion=4! mux. flvmux streamable=true name=mux \               
    ! rtmpsink location="${dest} live=1 flashver=FMLE/3.0(compatibble;FMSc/1.0) timeout=0"

In this command, the timeout parameter is set to 0, which means that the connection will not time out. You can adjust this value to suit your needs.

This is a completely useless answer. It is as if chatGPT is responding and not a human.

According to librtmp (see here) the timeout parameter is used when I am not receiving any data from the server and the default value is 120 seconds which is high enough.

It doesn't address my issue at all. I have zero connection issues.

Here is a rephrase of what I need: After I reboot the computer and start the GStreamer again, I want the output stream to run as flawlessly as it was the first time I started the live event.

I keep sending comments and it doesn't show up when I refresh the page until I post the next comment.

There is also no delete option. Only edit
