Not able to work with RTSP stream from WansView camera

[mkloock]

Hello,

So far, I enjoyed the plugin and I have already gotten one camera (camera A) working which streams MJPEG over http. This camera is a motionpie setup on a raspberry. The quality in the Home app is medium, not great.

So I went and added another commercial WansView 1080p camera which streams as RTSP. I was hoping that this might product better quality.

My Homebridge is running in a Debian 9 (Stretch) installation. ffmpeg is installed (and working with the MJPEG camera).

Unfortunately, I am not able to stream from rtsp. The ffmpeg connection gets initiated like this, similar to the MJPEG connection over http.

-re -i rtsp://192.168.1.21:554/live/ch1 -threads 0 -vcodec libx264 -an -pix_fmt yuv420p -r 30 -f rawvideo -tune zerolatency -vf scale=1280:720 -b:v 299k -bufsize 299k -payload_type 99 -ssrc 1 -f rtp -srtp_out_suite AES_CM_128_HMAC_SHA1_80 -srtp_out_params qnD98F94ccl0+w35ZmNnrBEvCIRHDZHDHondaudl srtp://192.168.1.17:65372?rtcpport=65372&localrtcpport=65372&pkt_size=1378

Unfortunately, no video stream is never received.

I verified with several apps (VLC and LiveCams Pro) to retrieve the video stream with the same URL and it works (authentication is off so that is not the issue).

running ffmpeg -re -i rtsp://192.168.1.21:554/live/ch1 test.mp4 yields the following:

Thanks for any suggestions or help!

Martin,

Please recheck ffmpeg flags during when you compile program from source. ffmget has to understand the stream that is coming from camera. My setup is:

ffmpeg version 3.3.4 Copyright (c) 2000-2017 the FFmpeg developers built with gcc 6.3.0 (Debian 6.3.0-18) 20170516 configuration: --disable-decoder=amrnb --disable-decoder=libopenjpeg --disable-mips32r2 --disable-mips32r6 --disable-mips64r6 --disable-mipsdsp --disable-mipsdspr2 --disable-mipsfpu --disable-msa --disable-libopencv --disable-podpages --disable-stripping --enable-avfilter --enable-avresample --enable-gcrypt --enable-gnutls --enable-gpl --enable-libass --enable-libbluray --enable-libbs2b --enable-libcaca --enable-libcdio --enable-libfdk-aac --enable-libfontconfig --enable-libfreetype --enable-libfribidi --enable-libgme --enable-libgsm --enable-libilbc --enable-libkvazaar --enable-libmp3lame --enable-libopencore-amrnb --enable-libopencore-amrwb --enable-libopenh264 --enable-libopenjpeg --enable-libopenmpt --enable-libopus --enable-libpulse --enable-librubberband --enable-libshine --enable-libsnappy --enable-libsoxr --enable-libspeex --enable-libtesseract --enable-libtheora --enable-libvidstab --enable-libvo-amrwbenc --enable-libvorbis --enable-libvpx --enable-libx265 --enable-libxvid --enable-libzvbi --enable-nonfree --enable-opengl --enable-openssl --enable-postproc --enable-pthreads --enable-shared --enable-version3 --incdir=/usr/include/arm-linux-gnueabihf --libdir=/usr/lib/arm-linux-gnueabihf --prefix=/usr --toolchain=hardened --enable-frei0r --enable-chromaprint ---enable-libx264 --enable-libiec61883 --enable-libdc1394 --disable-altivec --shlibdir=/usr/lib/arm-linux-gnueabihf

Very important flags are: --enable-libopenh264 --enable-libx264

Thank you. I was hoping to avoid a compile, especially since ffmpeg seems to work fine with my jpeg camera. But I might have to... will take me a while to figure out.

If you know of any step by step guide for ffmpeg, that would be great.

I used this compiled version that has omg enabled: https://www.npmjs.com/package/homebridge-camera-ffmpeg-omx sudo wget goo.gl/gMGA81 -O ffmpeg.deb sudo dpkg -i ffmpeg.deb

Cheers, Martin

Hi Martin,

If you are working with Debian please try to use:

deb http://www.deb-multimedia.org stretch main non-free

as additional repo (watch instruction on their page to add proper repo). First uninstall existing ffmpeg package. Then issue apt-get update && apt-get install ffmpeg. Their version works on my RPI.

thank you for your responses! Yes - I had moved to Debian from Raspberry Pi but had the same problem there.

So in general, you think the issue is with ffmpeg? If so, I will do my digging there - not an expert in ffmpeg but maybe this is the time to become one…

Cheers, Martin

Yes. I'm almost sure that is has something with ffmpeg (not an expert too). I run this setup on RPI, Synology DS416, pure Debian on PC, on OSX and didn't have any problems with homebridge and configuration. The only important part is correct ffmpeg.
