Dynamic, real time quality optimization of streamed video

Twitch is a video live streaming service and a subsidiary of Amazon. Twitch primarily focuses on video game live streaming, broadcasts of esports competitions, music and creative content. Twitch clients upload their encoded video to Twitch’s servers. The user generated content (UGC) is then transcoded. Transcoding is the process of decoding UGC, making alternations to it, and then encoding it again. During transcoding, video will be encoded at a lower bit rate or its resolution might be lowered.
