how to stream from raspberrypi pi camera using kvsWebRTCClientMaster app?

[kamlesh-solution]

Hi

i successfully setup kinesis webrtc in c sdk on my raspberrypi. but when i run kvsWebRTCClientMaster sample app for stream from my raspberrypi attached camera on signal channel its not streaming on signal channel i checked kvsWebRTCClientMaster sample app its stream sample video only.

How can i stream video from my raspberrypi attached pi camera on signal channel using kvsWebRTCClientMaster sample app what changes i need to make for the same?

Thanks.

Hello @kamlesh-solution ,

Are you saving the frames from the camera in a directory? If yes, you will need to modify the directory argument in https://github.com/awslabs/amazon-kinesis-video-streams-webrtc-sdk-c/blob/e2e2e69003a361bdc34e8b10e3c61e810711a582/samples/kvsWebRTCClientMaster.c#L35 and it should work.

Else, you will have to write the code to extract the frame from the camera at a specific rate and encode it into H.264 format and then send it over the signaling channel.

Considering you have a USB camera source, it is preferable to use the kvsWebRTCClientMasterGstreamerSample and tailor the pipeline to your use case. To get started, you can probably use the pipelines as suggested in the Producer SDK repo:

Hi disa

Thanks for reply when i compile this kvsWebRTCClientMasterGstreamerSample.c file i m getting include.h header not found error.

Can you tell me where i can get kvsWebRTCClientMasterGstreamerSample executable object file for stream directly from raspberrypi connected pi camera on signal channel?

Hello @kamlesh-solution ,

Can you share the log and steps you used to build the repo? The kvsWebRTCClientMasterGstreamerSample executable should be available in the build directory if the cmake.. and make steps succeed. As I mentioned in the previous comment, you will have to edit your GStreamer pipeline for your USB Camera. Edit the following line according to your setup: https://github.com/awslabs/amazon-kinesis-video-streams-webrtc-sdk-c/blob/9bf2865519cf16dbecb619ea1dd12c457ed35d4f/samples/kvsWebRTCClientMasterGstreamerSample.c#L132

Note: If you do not have GStreamer installed on your system, GStreamer related binaries will not be created. Make sure you have them installed using the steps in https://github.com/awslabs/amazon-kinesis-video-streams-producer-sdk-cpp/blob/master/install-instructions-linux.md

Hello @disa6302 this following is log after execute cmake command i found problem actually cmake command could not detect gstreamer on my raspberrypi see log ( -- No package 'gstreamer-1.0' found)

@kamlesh-solution ,

It looks like pkg_check_modules() is unable to find gstreamer-1.0. Could you run the following command and paste the output here? pkg-config --list-all.

Also, make sure you have followed the steps in https://github.com/awslabs/amazon-kinesis-video-streams-producer-sdk-cpp/blob/master/install-instructions-linux.md to install pkg-config, autoconf and gstreamer related packages.

@disa6302

this is my output of pkg-config --list-all and yes i have followed steps for install gsteramer related package using gstreamer i can stream video on video stream channel name but i could not using webrtc c sdk

I have this version of gstreamer installed gst-launch-1.0 --version gst-launch-1.0 version 1.14.4 GStreamer 1.14.4

@kamlesh-solution ,

pkg-config is unable to find gstreamer related packages. You will have to check where GStreamer related libraries are installed and then set the PKG_CONFIG_PATH environment variable to where the libs are located so that pkg_check_modules() can check the set path for GStreamer while running cmake.

kvsWebRTCClientMaster is only meant to stream the files that we recorded. If you want to stream from the webcam you can try running the ./kvsWebrtcClientMasterGstSample. However you need to install gstreamer in your platform first. You can do that by running $ sudo apt-get install gstreamer1.0-plugins-base gstreamer1.0-plugins-bad gstreamer1.0-plugins-good gstreamer1.0-plugins-ugly gstreamer1.0-tools

Hello @disa6302 , @chehefen

I got ./kvsWebrtcClientMasterGstSample compiled executable file on my another raspberrypi but when i run ./kvsWebrtcClientMasterGstSample file with default gstreamer pipeline raspberrypi sending stream over channel but i can't show video its showing only three color please check this preview image link I connected pi camera with raspberrypi if i need to change in gstreamer pipeline what should i change in gstreamer pipeline please help me?

[disa6302]

Can you share your pipeline here? Or, you can use the pipelines in https://github.com/awslabs/amazon-kinesis-video-streams-producer-sdk-cpp/blob/master/install-instructions-linux.md#running-the-gst-launch-10-command-to-start-streaming-from-usb-camera-source-which-has-h264-encoded-stream-already-in-ubuntu-and-raspberry-pi

@disa6302

Thanks default gstreamer pipeline worked for me now i can see streaming on aws media playback preview .

kinesis webrtc c sdk support raspberrypi zero w version?

[disa6302]

@kamlesh-solution ,

I do not think we tested on Raspberry Pi 0 but I do not see why not. As long as it runs Raspbian/Ubuntu OS, it should work.

[chehefen]

@kamlesh-solution can you close the issue if it's fixed? thanks
