The below are some common problems you might encounter when using the VLC media player. In general, a VLC alternative can solve this problem easily. Does anybody have a solution to this? It is driving me crazy. Everything worked great until this update. I have tried everything to solve the problem, installing the backup, uninstall and install, with no success. Now all I get is green lines over the movie. Then I get a notice about an update, which I did. I have been using VLC media player for a while and was pleased with it. It is able to play incomplete, unfinished or damaged video, but it will drive you crazy sometimes.įor example, here is a true story. VLC is a free, open-source, portable, and cross-platform media player and streaming media server developed by the VideoLAN project. You can find a suitable VLC alternative to play video and audio files. Have you ever used VLC media player? This post is going to show you some excellent VLC alternatives for Windows/Linux/Mac. Choose the best VLC alternative depends on your actual situation. This post lists different VLC alternatives for Windows/Mac.

Running in cron for example to change the exposure settings at certain times of day. Scripts can be use to make adjustments and run manually or with cron. V4l2 utilities provide the tools to manage USB webcam setting and information. For the similar error with setproctitle() add option WITH_SETPROCTITLE=0. If the compiler reports about a missing function pthread_get_name_np() (or similar), add option WITH_PTHREAD_NP=0 (it's enabled by default). To enable GPIO support install libgpiod and pass option WITH_GPIO=1. Alpine: sudo apk add libevent-dev libbsd-dev libjpeg-turbo-dev musl-dev.Debian/Ubuntu: sudo apt install build-essential libevent-dev libjpeg-dev libbsd-dev.Add libgpiod-dev for WITH_GPIO=1 and libsystemd-dev for WITH_SYSTEMD=1. Raspbian: sudo apt install libevent-dev libjpeg8-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). 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.
