RTSP Streaming

[MrDaniel]

Hello,

I saw your project and i was curious to know if this could work with OpenCV?

Could you publish and recieve raw images as byte arrays to and from an Rtsp stream?

[berfi]

I want test streaming via VLC client. But the pi-streamer always prompts an error "Memory overflow" after vlc tries to establish connection. Any light on the issue wellcome

[berfi]

I solved this problem. The problem solved by issuing root permission for my application.

fixed.thanks

Can we use this to push RTP audio streams from a web browser to a digital amp which listens to RTP audio streams?

Hi,
I am very interested about your project.
So, how do I install it on my Pi?
Thanks,

hello,

Is there a way to store the video diectly on the Pi?

But getting back to your question, so yes, it sounds like raspivid and cvlc do accomplish what my application does. In regards to high and low resolution, I think that's theoretically possible (depending on the resolution), though I don't know if this is something the MMAL API supports (I have not looked into this yet). If MMAL API does support this, then there's no reason why my app can't forward a another stream to a different port.

That being said, are you also expecting the application to perform the record and motion detection? I'm not sure if the Pi has enough horse power to perform motion detection as well as recording at the same time. Or are you suggesting these are done on the receiver end?

Very interesting project! A quick aside on the subjects above: multi-resolution recording is indeed possible by utilizing a splitter and resizer in the encoding pipeline. Also, recent firmwares have the ability to include motion estimation data from the H.264 encoder in the stream, which can be used to implement a crude form of motion detection with minimal processing on the Pi (although those doc links are for my Python-based camera library, it's all implemented with MMAL underneath).

hi,would you share how we can modify width,height and fps?

[MuhsinFatih]

Hi,
Is there a way to decrease resolution and fps? It's working now, but I need an instant transfer from raspberry pi to computer. There's a latency around 5 seconds. I've decreased network cache size in vlc player to 50 (This is the minimum value I can see the video), still there's a 1 second latency. Resolution and fps is not that important in my project (It's a quadcopter). If there's a way to decrease resolution and fps, please tell it in such a way that a newbie can understand

Hello there,

I managed to this project correctly and it runs very well when i see it in vlc.
Now i want to merge it in wowza. As soon as I create a stream with the rtsp address of the pi stream
it stops and gives me the following error
app: ./src/sx_mgmt_rtsp.c:520: tcp_listener_thread: Assertion 'rc == 0' failed.

After deleting the stream and waiting for about 1/2 minute it can run again, but if i do the same to
view it in wowza it goes the same error again. What should i do?

Any news on customizing the camera parameters ? resolution would be a great start.
thanks.

A little off-topic (not RTSP Streaming) but I was able to get 250 msec latency with 640x480 30 fps using the method below. Certainly a lot better than several seconds delay. http://www.raspberrypi.org/forums/viewt ... 43&t=93615

Here it is what it looks like streaming over wifi:

"app" not work for me

When i started read stream from remote device i have crash on RPI :

MGMT_RTSP: RTSP Request [session ID = 0]:

Segmentation fault

i'm also getting a lot of segmentation faults after a while of streaming.

[MatST]

This is working perfectly but how can I adjust size, fps etc to reduce bandwith?

[The German]

Segmentation fault is all the app provides when a client connects (Jessie on Pi model 3).
