MPL
- 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!
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.
File Structure
The values are written only when they are equal in every file.

Video Part
This part contains time stamps of the corresponding MTS file. Right before the first occurance of one of such part is a char that tells how many such parts are following.
This part is 66 bytes in size.
char[4] {1, 3, 5, 0x81} char[4] {0, 0, 0, 0} char[2] {A, B} (A<<8 + B).MTS = 00012.MTS, A=0, B=0x0C; char[1] {0x1E} char[1] {C} C = BCD (Century) char[1] {D} D = BCD (Decade) char[1] {E} E = BCD (Month) char[1] {F} F = BCD (Day) char[1] {G} G = BCD (Minute)
char[1] {H} H = BCD(Second) char[2] {0x90, 0x0A} char[11] date as string (null terminated; no time) e.g. "2010. 4.18" char[2] {0, 0}
char[4] {0, 0, 0, 0} char[4] {0, 0, 0, 0} char[4] {0, 0, 0, 0} char[4] {0x11, 0x10, 0, 0}
char[4] {0, I, J, _} I = 0x65 or 0x66; J=2 for SH or 0 for FHD char[1] {0x03} char[3] 'FHD'; 'SH\0' video format char[4] {0, 0, 0, 0} char[4] {0xFF, 0xFF, 0xFF, 0xFF}
char[2] {0, 0}
A and B tell the name of the corresponding MTS file e.g. (A<<8 + B).MTS = 00012.MTS, A=0, B=0x0C
