Elte: /* Time Stamp Parser */

* Extensions: mpl, mpls
* This is a playlist file used in BluRays and AVCHD (Lite) video camcorders and foto cams.

'''Please correct or beautify the language used in this article!'''
== Introduction ==
This site tries to collect information about this file. This information partly comes from reverse engineering. There is no free specification available on the net.

The intention was to extract the time stamps of the captured videos from the mpl files. The Panasonic GH1 doesn't write the time stamp into the SEI part of the h264 stream. Other cams are known to do this (e.g. Canon HG-20):

http://forum.videohelp.com/threads/296805-Reading-AVCHD-Playlist-files-BDMV-Playlist-*-mpl

This document might be helpful to understand the connection between a playlist file a cpi file and the actual stream file.

http://www.blu-raydisc.com/Assets/Downloadablefile/BD-RE_Part3_V2.1_WhitePaper_080406-15271.pdf

= Technical Part =

The file is located in a directory structure like this:
/BDMV/PLAYLIST/00000.MPL
it corresponds with the files in this directory:
/BDMV/STREAM/00000.MTS

In Bluray specification the files hav a differnt endig: *.mpls and *.m2ts.

The following information are reverse engineered from MPL files from a [[Panasonic]] GH1 foto cam.

This file sizes are known:
* 638 bytes
* 800 bytes
* 962 bytes
* 1124 bytes
* 1286 bytes
* 1448 bytes
* 1772 bytes
* 2096 bytes
* 2420 bytes

The difference in size is always a multiple of 162 bytes.

== File Structure ==

The values are written only when they are equal in every file.

Elte: /* Time Stamp Parser */

* Extensions: mpl, mpls
* This is a playlist file used in BluRays and AVCHD (Lite) video camcorders and foto cams.

'''Please correct or beautify the language used in this article!'''
== Introduction ==
This site tries to collect information about this file. This information partly comes from reverse engineering. There is no free specification available on the net.

The intention was to extract the time stamps of the captured videos from the mpl files. The Panasonic GH1 doesn't write the time stamp into the SEI part of the h264 stream. Other cams are known to do this (e.g. Canon HG-20):

http://forum.videohelp.com/threads/296805-Reading-AVCHD-Playlist-files-BDMV-Playlist-*-mpl

This document might be helpful to understand the connection between a playlist file a cpi file and the actual stream file.

http://www.blu-raydisc.com/Assets/Downloadablefile/BD-RE_Part3_V2.1_WhitePaper_080406-15271.pdf

= Technical Part =

The file is located in a directory structure like this:
/BDMV/PLAYLIST/00000.MPL
it corresponds with the files in this directory:
/BDMV/STREAM/00000.MTS

In Bluray specification the files hav a differnt endig: *.mpls and *.m2ts.

The following information are reverse engineered from MPL files from a [[Panasonic]] GH1 foto cam.

This file sizes are known:
* 638 bytes
* 800 bytes
* 962 bytes
* 1124 bytes
* 1286 bytes
* 1448 bytes
* 1772 bytes
* 2096 bytes
* 2420 bytes

The difference in size is always a multiple of 162 bytes.

== File Structure ==

The values are written only when they are equal in every file.

* Extensions: mpl, mpls
* This is a playlist file used in BluRays and AVCHD (Lite) video camcorders and foto cams.

This site tries to collect information about this file. This information partly comes from reverse engineering. There is no free specification available on the net.

The file is located in a directory structure like this:
/BDMV/PLAYLIST/00000.MPL
it corresponds with the files in this directory:
/BDMV/STREAM/00000.MTS

The following information are reverse engineered from MPL files from a [[Panasonic]] GH1 foto cam.

The following file sizes are known:
* 638 bytes
* 800 bytes
* 962 bytes
* 1124 bytes
* 1286 bytes
* 1448 bytes
* 1772 bytes
* 2096 bytes
* 2420 bytes

The difference in size is always a multiple of 162 bytes.
