|
|
Present the content of an H.264 (MPEG\-4/AVC), H.262 (MPEG\-2) or AVS
|
|
elementary stream as a sequence of characters, representing access
|
|
units/MPEG\-2 items/AVS items.
|
|
(Note that for H.264 it is access units and not frames that are
|
|
represented, and for H.262 it is items and not pictures.)
|
|
.SS "Files:"
|
|
.TP
|
|
<infile>
|
|
is the Elementary Stream file (but see \fB\-stdin\fR below)
|
|
.SS "Switches:"
|
|
.TP
|
|
\fB\-verbose\fR, \fB\-v\fR
|
|
Preface the output with an explanation of the
|
|
characters being used.
|
|
.TP
|
|
\fB\-stdin\fR
|
|
Take input from <stdin>, instead of a named file
|
|
.TP
|
|
\fB\-max\fR <n>, \fB\-m\fR <n>
|
|
Maximum number of entities to read
|
|
.TP
|
|
\fB\-pes\fR, \fB\-ts\fR
|
|
The input file is TS or PS, to be read via the
|
|
PES\->ES reading mechanisms
|
|
.TP
|
|
\fB\-hasheos\fR
|
|
Print a # on finding an EOS (end\-of\-stream) NAL unit
|
|
rather than stopping (only applies to H.264)
|
|
.TP
|
|
\fB\-es\fR
|
|
Report ES units, rather than any 'higher' unit
|
|
(not necessarily suppported for all file types)
|
|
.TP
|
|
\fB\-gop\fR
|
|
Show the duration of each GOP (for MPEG\-2 steams)
|
|
OR the distance between random access points (H.264)
|
|
.TP
|
|
\fB\-fr\fR
|
|
Set the video frame rate (default = 25 fps)
|
|
.SS "Stream type:"
|
|
.IP
|
|
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.
|
|
.IP
|
|
For AVS data, the program will never guess correctly, so the user must
|
|
specify the file type, using \fB\-avs\fR.
|
|
.IP
|
|
If input is from standard input (via \fB\-stdin\fR), 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.
|
|
.TP
|
|
\fB\-h264\fR, \fB\-avc\fR
|
|
Force the program to treat the input as MPEG\-4/AVC.
|
|
.TP
|
|
\fB\-h262\fR
|
|
Force the program to treat the input as MPEG\-2.
|
|
.TP
|
|
\fB\-avs\fR
|
|
Force the program to treat the input as AVS.
