The output of the muxer consists of a single line of the form: abort will cause whole process to fail in case of failure By default audio frames are converted to signed Syntax is "id=x,streams=a,b,c id=y,streams=d,e" with x and y being the IDs and can play only I-frames in the #EXT-X-BYTERANGE mode.
