No video_pad and audio_pad on rtsp source

[HoangTienDuc]

Hi @notedit , thank for your work, your code helps people who are new to streaming like me a big step forward.
With source as TestSource, FileSource; your code works perfectly, however with the source being rtsp, the code has a bug as below:

Code:

url = "rtsp://admin:[email protected]/cam/realmonitor?channel=1&subtype=0"
source  = RTSPSource(url)

# url = "9-7-2023-23-06_1.mp4"
# source = FileSource(url)

pc.add_stream(source)

Bug:

I see you already have parsebin.connect('pad-added', self._new_parsed_pad) but it doesn't seem to work. Please help me check this issue

I'v met the same problem, too. Have you solved it yet?
