// until the file is exhausted. Returns a coded string representing the
// segments and timestamps of the extracted frames.
// The start of each media segment is designated by "NewSegment", similarly
// the end of each segment by "EndOfSegment". Segments end when one or more
// frames are parsed from an append. If the append contains a partial frame
// the segment will continue into the next append.
// Parsed frame(s) are represented as "{ xxK yyK zzK }" Where xx, yy, and zz

// "NewSegment{ 0K 23K 46K }EndOfSegment"
// "NewSegment{ 0K }{ 23K }{ 46K }EndOfSegment"
// "NewSegment{ 0K }{ 23K }EndOfSegmentNewSegment{ 46K }EndOfSegment"
