Transmuxing
Transmuxing is the process of converting a media file from one container format to another without re-encoding the underlying audio and video streams. It involves repackaging the compressed data into a different wrapper, which is faster and preserves quality compared to transcoding. This is commonly used in video streaming to adapt content for various devices and protocols.
Developers should learn transmuxing when working with video streaming applications, media servers, or content delivery networks to efficiently serve media across different platforms. It's essential for real-time streaming scenarios like live broadcasts or adaptive bitrate streaming (e.g., converting MPEG-TS to MP4 for HLS or DASH), as it reduces latency and computational overhead by avoiding full re-encoding.
