Parser for AVCHD/Blu-ray formats
|
|
|
|
Notice: This parser is based off reverse-engineering efforts.
|
|
It is NOT based on official specifications, and is subject to change as
|
|
more information becomes available. There's a lot of guesswork here, so if you find
|
|
that something disagrees with an official specification, please change it.
|
|
|
|
Notice: This parser has NOT been tested on Blu-ray disc data, only on files
|
|
taken from AVCHD camcorders.
