Pi 3 - Hardware acceleration seems not working

[titoudoc]

Hi, first of all, thanks for your hard work ! It's wonderful to be able to use the Nest Cam and Hello in HomeKit with your homebridge plugin.

I run into some kind of issue. Wether the UseOMX is set to true or false, it seems there is no upgrade in performance. The live stream remain extremely slow. I don't know what else could I try... any help would be greatly appreciated.

I've compiled FFmpeg with h264_omx following this Wiki : https://github.com/KhaosT/homebridge-camera-ffmpeg/wiki/Raspberry-PI.

My build is fine as confirmed with the command ./ffmpeg -encoders | grep h264_omx returning ffmpeg version N-92786-g4096c670ab Copyright (c) 2000-2018 the FFmpeg developers built with gcc 6.3.0 (Raspbian 6.3.0-18+rpi1+deb9u1) 20170516 configuration: --prefix=/usr/local --arch=armel --target-os=linux --enable-omx-rpi --enable-nonfree --enable-gpl --enable-libfdk-aac --enable-mmal --enable-libx264 --enable-decoder=h264 --enable-network --enable-protocol=tcp --enable-demuxer=rtsp libavutil 56. 25.100 / 56. 25.100 libavcodec 58. 42.104 / 58. 42.104 libavformat 58. 25.100 / 58. 25.100 libavdevice 58. 6.101 / 58. 6.101 libavfilter 7. 46.101 / 7. 46.101 libswscale 5. 4.100 / 5. 4.100 libswresample 3. 4.100 / 3. 4.100 libpostproc 55. 4.100 / 55. 4.100 V..... h264_omx OpenMAX IL H.264 video encoder (codec h264).

My config.json is the following { "platform": "Nest-cam", "access_token": "NA", "useOMX": true, }

Any idea how to improve live stream ? Thanks in advance.

After further test, hardware acceleration is working... but the video is very slow. Probably not enough horse power on the Pi to transcode the video stream... Any way to improve this ?

I'm afraid not...

I've update to version 0.017 and update config.json and it's near perfect, almost fluid ! Thanks !
