NAME¶
esdots - Analyze the video items contained in an elementary stream
SYNOPSIS¶
esdots [
switches]
<infile>
DESCRIPTION¶
- TS tools version 1.11, esdots built Nov 11 2008
17:15:46
- 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.)
Files:¶
- <infile>
- is the Elementary Stream file (but see -stdin
below)
Switches:¶
- -verbose, -v
- Preface the output with an explanation of the characters
being used.
- -stdin
- Take input from <stdin>, instead of a named file
- -max <n>, -m <n>
- 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 suppported 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.
