Abstract
An encodingless transmuxer produces a manifest file and segments for streaming media content over different streaming protocols without encoding or otherwise modifying the binary data from the original encoding of the media content file. The transmuxer detects key frame positions from the media content file metadata. The transmuxer maps segment start times to a subset of the identified key frames based on a segment duration parameter. The transmuxer generates a manifest file listing the segments with each segment identifier comprising a timestamp specifying a time offset for the key frame at which the segment commences. In response to a request for a particular segment, the transmuxer or a streaming server copies or reuses from the original media content file, the binary data for the key frame that commences the particular segment up to the bit immediately before the start of the next segment key frame.
