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.
