PL_MPEG - MPEG1 Video decoder, MP2 Audio decoder, MPEG-PS demuxer
Single-file MIT licensed library for C/C++
See pl_mpeg.h for the documentation.
This is meant as a simple way to get video playback into your app or game. Other solutions, such as ffmpeg require huge libraries and a lot of glue code.
MPEG1 is an old and inefficient codec, but it's still good enough for many use cases. All patents related to MPEG1 and MP2 have expired, so it's completely free now.
This library does not make use of any SIMD instructions, but because of the relative simplicity of the codec it still manages to decode 4k60fps video on a single CPU core (on my i7-6700k at least).
- pl_mpeg_extract_frames.c extracts all frames from a video and saves them as PNG.
- pl_mpeg_player.c implements a video player using SDL2 and OpenGL for rendering.
Encoding for PL_MPEG
Most MPEG-PS (
containing MPEG1 Video ("mpeg1") and MPEG1 Audio Layer II ("mp2") streams should
work with PL_MPEG. Note that
.mpg files can also contain MPEG2 Video, which is
not supported by this library.
You can encode video in a suitable format using ffmpeg:
ffmpeg -i input.mp4 -c:v mpeg1video -c:a mp2 -format mpeg output.mpg
If you just want to quickly test the library, try this file:
- no error reporting. PL_MPEG will silently ignore any invalid data.
- the pts (presentation time stamp) for packets in the MPEG-PS container is ignored. This may cause sync issues with some files.
- no seeking.
- bugs, probably.
