NAME¶
esfilter - Output a filtered or truncated version of a ES
SYNOPSIS¶
esfilter [
actions/switches]
<infile>
<outfile>
DESCRIPTION¶
- TS tools version 1.11, esfilter built Nov 11 2008
17:15:39
- Output a filtered or truncated version of an elementary
stream. The input is either H.264 (MPEG-4/AVC) or H.262 (MPEG-2). The
output is either an elementary stream, or an H.222 transport stream
- If output is to an H.222 Transport Stream, then fixed
values for the PMT PID (0x66) and video PID (0x68) are used.
Files:¶
- <infile>
- is the input elementary stream (but see -stdin
below).
- <outfile> is the output stream, either an equivalent
elementary
- stream, or an H.222 Transport Stream (but see
-stdout and -host below).
Actions:¶
- -copy
- Copy the input data to the output file (mostly useful as a
way of truncating data with -max)
- -filter
- Filter data from input to output, aiming to keep every
<n>th frame (where <n> is specified by -freq).
- -strip
- For H.264, output just the IDR and I pictures, for H.262,
output just the I pictures, but see -allref below.
Switches:¶
- -verbose, -v
- Output extra (debugging) messages
- -quiet, -q
- Only output error messages
- -stdin
- Take input from <stdin>, instead of a named file
- -stdout
- Write output to <stdout>, instead of a named file
Forces -quiet.
- -host <host>, -host
<host>:<port>
- Writes output (over TCP/IP) to the named <host>,
instead of to a named file. If <port> is not specified, it defaults
to 88. Implies -tsout.
- -max <n>, -m <n>
- Maximum number of frames to read (for -filter and
-strip), or ES units/NAL units (for -copy).
- -freq <n>
- Specify the frequency of frames to try to keep with
-filter. Defaults to 8.
- -allref
- With -strip, keep all reference pictures (H.264) or
all I and P pictures (H.262)
- -tsout
- Output data as Transport Stream PES packets (the default is
as Elementary Stream)
- -pes, -ts
- The input file is TS or PS, to be read via the PES->ES
reading mechanisms. Not allowed with -stdin.
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.
- 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.
