RTSP stream is slow to start
Using MobileVLCKit in Swift, I load a live rtsp stream with:
let url = URL(string: "rtsp://192.168.1.12:8554/live")
let media = VLCMedia(url: url!)
mediaPlayer.media = media
mediaPlayer.delegate = self as? VLCMediaPlayerDelegate
mediaPlayer.drawable = self.cameraView
mediaPlayer.play()
The code is working, though the video takes up to 20-30 seconds to start. And when it does start, the image is already complete. I don't really know what's happening, but it feels like the video stream is faster to load when the camera is moving than when it is not moving.
I tried to play with some options, though I haven't found any documentation. I added:
media.addOptions([
"network-caching": 0,
"live-caching": 0,
"rtp-caching": 0,
"rtsp-caching": 0,
"realrtsp-caching": 0
])
But my feeling is that if this has any effect at all, it would reduce the delay in the video, but not solve the slow-start, right?
Is there a way to get a quick start that would show the video stream even if the frame is not complete (I believe that the VLC Mobile app does that, from what I can observe).
