OBS Free Streaming &  Recording

Open Broadcaster Software and also known as OBS is a free and open source streaming and recording program maintained by the OBS Project. The program has support for Windows 7 and later, OS X 10.8 and later, and Linux.

Open Broadcaster Software is a free and open source software suite for recording and live streaming.
Written in C and C++, OBS provides real-time source and device capture, scene composition, encoding, recording and broadcasting.
Transmission of data is done via the Real Time Messaging Protocol and can be sent to any RTMP supporting destination (e.g. YouTube) including many presets for streaming websites such as Twitch.tv and DailyMotion.-Justplay

For video encoding, OBS is capable of using the x264 free software library,

Intel Quick Sync Video and Nvidia NVENC to encode video streams into the H.264/MPEG-4 AVC format. Experimental support for AMD VCE encoding was added in OBS Studio version 0.16.0.
Audio can be encoded using either the MP3 or AAC codecs.

Open Broadcaster Software started out as a small project created by Hugh “Jim” Bailey, but quickly grew with the help of many online collaborators working both to improve OBS and spread the knowledge about the program.

In 2014, development started on a rewritten version known as OBS Multiplatform (later renamed OBS Studio) for multiplatform support,
a more thorough feature set, and a more powerful API.[9] As of v18.0.1 of OBS Studio,
OBS Classic is no longer supported due to the former reaching near-full feature parity with the latter, though the download for Classic is still available.

There are challenges with streaming content on the Internet. If the user does not have enough bandwidth in their Internet connection,
they may experience stops in the content and some users may not be able to stream certain content due to not having compatible computer or software systems.

Some popular streaming services are the video sharing website YouTube, which contains user-uploaded videos on a huge range of topics;
Twitch.tv, which live streams the playing of video games;
and Netflix, which streams movies and TV shows.
