A gentle introduction to video technology, although it's aimed at software developers / engineers, we want to make it easy for anyone to learn. This idea was born during a mini workshop for newcomers to video technology. The goal is to introduce some digital video concepts with a simple vocabulary, lots of visual elements and practical examples when possible, and make this knowledge available everywhere. Please, feel free to send corrections, suggestions and improve it.

rtsp-simple-server is a ready-to-use and zero-dependency server and proxy that allows users to publish, read and proxy live video and audio streams through various protocols like RTSP, RTMP, HLS. It publish and read live streams to the server. It acts as a proxy and serve streams from other servers or cameras, always or on-demand.

Great for rough processing of large video files taken from a video camera, GoPro, drone, etc. It lets you quickly extract the good parts from your videos and discard GBs of data without losing quality. It doesn't do any decoding / encoding and is therefore extremely fast. This app uses the awesome ffmpeg (included) for doing the grunt work. Since LosslessCut is based on Chromium and uses the HTML5 video player, not all ffmpeg supported formats will be supported. The following formats/codecs should generally work: MP4, MOV, WebM, MKV, OGG, WAV, MP3, AAC, H264, Theora, VP8, VP9 For more information about supported formats / codecs, see https://www.chromium.org/audio-video. Note that the MPEG TS format is not supported. See known issues.

Spend more time building and less time learning a new API. Its feature include PeerConnection API support for DataChannels, Send/Receive audio and video, Renegotiation. It provides API with direct RTP/RTCP access, API also allows developer to pass their own packetizer, Opus, PCM, H264, VP8 and VP9 packetizer, Sender/Receiver Reports, Easy integration with x264, libvpx, GStreamer and ffmpeg and lot more.

Kdenlive relies on several other open source projects, such as FFmpeg and MLT video framework. It is designed to answer all needs, from basic video editing to semi-professionnal work. Kdenlive can read, edit and export Flash video. Kdenlive supports most audio formats for reading, mixing and exporting. It also offers experimental support for non-destructive audio and video codec.

This is a docker image for Janus Webrtc Gateway. Janus Gateway is still under active development phase. So, as the official docs says, some minor modification of the middleware library versions happens frequently. I try to deal with such a chage as much as I can. If you need any request about this repo, free to contact me. About the details of setup for this docker image, you should read the official docs https://janus.conf.meetecho.com/index.html carefully. I think that janus is better for webinar(web seminar), and jitsi is better for web conference system. The scalability of the current Jitsi Video Bridge(20181007) is poor because of having no local recording file(I'm not sure of this..). https://www.youtube.com/watch?v=OHHoqKCjJ0E Jitsi last-n + VP8 simulcasting has the very good performance for web conference https://jitsi.org/wp-content/uploads/2016/12/nossdav2015lastn.pdf For the video format, janus recording is per video streaming, jitsi is for mixed video conference by using chrome headlesss + ffmpeg(alsa, libxcb). From these points, janus is suitable for webinar, jitsi is for web conference. Of course, both WebRTC SFU are amazing work!! I'm using both.

Unfortunately it was deprecated, so I decided to write this one. Most of the code in here will be in c but don't worry: you can easily understand and apply it to your preferred language. FFmpeg libav has lots of bindings for many languages like python, go and even if your language doesn't have it, you can still support it through the ffi (here's an example with Lua).

SRS (Simple Realtime Server) is a simple, high efficiency and realtime video server, supports RTMP/WebRTC/HLS/HTTP-FLV/SRT. SRS is industrial-strength live streaming cluster, for the best conceptual integrity and the simplest implementation. SRS provides variety of inputs, for example, Push RTMP to SRS, Push RTSP/UDP/FLV to SRS, Pull Stream to SRS. SRS can transform the RTMP to other protocols or deliveries, for example, RTMP Transcode, Snapshot, Forward to Other Servers, Transmux to HTTP-FLV, Transmux to HLS, Transmux to HDS, Transmux SRT, DVR to FLV/MP4. SRS canbe used in CDN for large stream clusters, for example, RTMP Cluster、 OriginCluster, VHOST, Reload, HTTP-FLV Cluster.
