stream_type - attempt to determine if an input stream is TS, PS,
or ES
stream_type [switches] <infile>
- TS tools version 1.11, stream_type built Nov 11 2008 17:15:48
- Attempt to determine if an input stream is Transport Stream, Program
Stream, or Elementary Stream, and if the latter, if it is H.262 or H.264
(i.e., MPEG-2 or MPEG-4/AVC respectively). The mechanisms used are fairly
crude, assuming that: - data is byte aligned - for TS, the first byte in
the file will be the start of a NAL unit,
- and PAT/PMT packets will be findable
- - for PS, the first packet starts immediately at the start of the
- file, and is a pack header
- - if the first 1000 packets could be H.262 *or* H.264, then the data
- is assumed to be H.264 (the program doesn't try to determine sensible
sequences of H.262/H.264 packets, so this is a reasonable way of
guessing)
- It is quite possible that data which is not relevant will be
misidentified
- The program exit value is: * 10 if it detects Transport Stream, * 11 if it
detects Program Stream, * 12 if it detects Elementary Stream containing
H.262 (MPEG-2), * 14 if it detects Elementary Stream containing H.264
(MPEG-4/AVC), * 5 if it looks like it might be PES, * 9 if it really
cannot decide, or * 0 if some error occurred

- -verbose,

- Output more detailed information about how it is making its decision
- -quiet,
-q
- Only output error messages
