The entire wiki has been moved to a GitHub pages site: ld-decode documentation

The reason for this change is to both modernize the documentation and make it possible for anyone to update, change and correct the documentation through the standard GitHub PR mechanisms. If you are interested in contributing to the documentation please see the instructions available from the ld-decode documentation GitHub

The original wiki page below will be available until 2025-12-20. Do not update this wiki.

ld-ldf-reader is a streaming decompressor for .ldf files that can jump to a specific location in the file. It is very lightly modified ffmpeg library sample code and is mostly used by ld-decode to support seamless seeking inside .ldf files, therefore it only outputs via standard output.

NOTE: This program only exists because of an ffmpeg CLI program bug preventing seeking deep into a file, so it may (or may not) go away after the move to Ubuntu 20.04.

usage: ld-ldf-reader infile [seek location] | (consumer)
