Files

in_file

is an H.222 Transport Stream file (but see -stdin)

Switches

-err stdout

Write error messages to standard output (the default)

-err stderr

Write error messages to standard error (Unix traditional)

-stdin

Input from standard input, instead of a file

-v, -verbose

Output extra information about packets

-q, -quiet

Only output error messages

-max max_units, -m max_units

Maximum number of entities to read

-pes, -ts

The input file is TS or PS, to be read via the PES->ES reading mechanisms

-hasheos

Print a # on finding an EOS (end-of-stream) NAL unit rather than stopping (only applies to H.264)

-es

Report ES units, rather than any 'higher' unit (not necessarily supported for all file types)

-gop

Show the duration of each GOP (for MPEG-2 steams) OR the distance between random access points (H.264)

-fr

Set the video frame rate (default = 25 fps)

Stream type:

If input is from a file, then the program will look at the start of the file to determine if the stream is H.264 or H.262 data. This process may occasionally come to the wrong conclusion, in which case the user can override the choice using the following switches.

For AVS data, the program will never guess correctly, so the user must specify the file type, using -avs.

If input is from standard input (via -stdin), then it is not possible for the program to make its own decision on the input stream type. Instead, it defaults to H.262, and relies on the user indicating if this is wrong.

-h264, -avc

Force the program to treat the input as MPEG-4/AVC.

-h262

Force the program to treat the input as MPEG-2.

-avs

Force the program to treat the input as AVS.
