Add libgpiod-dev for WITH_GPIO=1 and libsystemd-dev for WITH_SYSTEMD=1 and libasound2-dev libspeex-dev libspeexdsp-dev libopus-dev for WITH_JANUS=1. Raspbian: sudo apt install libevent-dev libjpeg9-dev libbsd-dev.
Arch: sudo pacman -S libevent libjpeg-turbo libutil-linux libbsd. You'll need make, gcc, libevent with pthreads support, libjpeg9/ libjpeg-turbo and libbsd (only for Linux). You need to download the µStreamer onto your system and build it from the sources. If you need a high-quality image with high FPS - µStreamer for the win. If you're going to live-stream from your backyard webcam and need to control it, use mjpg-streamer. Each new frame is matched with the previous one first by length, then using memcmp(). With the -drop-same-frames=20 option enabled, µStreamer will drop all the matching frames (with a limit of 20 in a row). There's no need to stream the same image over the net several times a second. The idea is that HDMI is a fully digital interface and each captured frame can be identical to the previous one byte-wise. With this in mind, along with needing multithreading and JPEG hardware acceleration in the future, I decided to make my own stream server from scratch instead of supporting legacy code.Ģ This feature allows to cut down outgoing traffic several-fold when streaming HDMI, but it increases CPU usage a little bit. Alas, the patch is far from perfect and I can't guarantee it will work every time - mjpg-streamer's source code is very complicated and its structure is hard to understand. Static images by HTTP to save the trafficĪccess to webcam controls (focus, servos)ġ Long before µStreamer, I made a patch to add DV-timings support to mjpg-streamer and to keep it from hanging up no device disconnection. ΜStreamer is very similar to mjpg-streamer with input_uvc.so and output_http.so plugins, however, there are some major differences. 
ΜStreamer is a part of the PiKVM project designed to stream VGA and HDMI screencast hardware data with the highest resolution and FPS possible. All new browsers have native support of this video format, as well as most video players such as mplayer, VLC etc. ΜStreamer is a lightweight and very quick server to stream MJPEG video from any V4L2 device to the net.
