Entering camera stream in iOS Home app crashes PiCamera_accessory.js

[pawelrup]

Hi! When I enter camera stream in iOS Home app PiCamera_accessory.js crashes.

bitrate:  299
avconv stream:  -f video4linux2 -i /dev/video0 -s 640:480 -threads auto -vcodec h264 -an -pix_fmt yuv420p -f rawvideo -tune zerolatency -vf scale=w=640:h=480 -b:v 100k -bufsize 200k -payload_type 99 -ssrc 1 -f rtp -srtp_out_suite AES_CM_128_HMAC_SHA1_80 -srtp_out_params gAi3S7pQdEW/Z7GPqOGtV8TgR/2xLvHcUXtD+Lcv srtp://192.168.1.14:60622?rtcpport=60622&localrtcpport=60622&pkt_size=1378

      throw er; // Unhandled 'error' event
      ^

Error: spawn avconv ENOENT

If it could help, I have Raspbery PI Zero W with Camera v2.1 and 16GB SD Card, clean Raspbian Stretch Lite installed from raspberrypi.org with enabled camera using sudo raspi-config and HAP-NodeJS installed as recommended on instalation guide.

[theopoon]

Can you confirm avconv is installed? on some pi images it does not.

[pawelrup]

I installed avconv with libav-tools and it's not crashing now. In Home app on main screen it refreshes screenshot every about 10 seconds, but when I will enter camera to see live streaming it's loading for 30s and displays "No response. This camera is not responding".

[theopoon]

Log the streaming command to console, test the command in terminal by itself to see any error(s)

[pawelrup]

This is all console log I have until it shows "No response".

[theopoon]

that looks normal, I am out of idea then, any chance firewall settings?

[pawelrup]

I did not install / enable firewall. I will try with raspbian jessie instead of stretch now.

[diarmuidie]

I had a similar issue and it turned out that /dev/video0 wasn't present.

I was able to enable it with:

sudo rpi-update # to make sure the v4L2 drive is available.
sudo modprobe bcm2835-v4l2 # to load it and create /dev/video0

Once that was enabled the video stream worked. Hope this helps!

[diarmuidie]

FYI @pawelrup you have to escape the & characters in the avconv command (in the srtp URL), by adding a backslash (\) before them, when executing it directly on the command line:

pi@raspberrypi:~ $ avconv -f video4linux2 -i /dev/video0 -s 640:480 -threads auto -vcodec h264 -an -pix_fmt yuv420p -f rawvideo -tune zerolatency -vf scale=w=640:h=480 -b:v 100k -bufsize 200k -payload_type 99 -ssrc 1 -f rtp -srtp_out_suite AES_CM_128_HMAC_SHA1_80 -srtp_out_params N7oMKWwxJRoFsp3AnorThVTxHAylejx9qvinlVp1 srtp://192.168.178.37:58504?rtcpport=58504\&localrtcpport=58504\&pkt_size=1378

I have a similar issue, runs this:

Gets "/dev/video0" not found, runs "sudo modprobe bcm2835-v4l2". Tehn it gets better but not without errors:

Any ideas?

[matsekberg]

But it seems to work on the Home-app :) Streaming but slow. And it seems to halt after a wile. Though it says "Live".
Guess it is raspberry pi zero that is too weak to stream properly.

[jonerikandersen]

Yes. In your comment you need to remove "stream :"

Try to post then. I have the same issue.
