FFmpeg is a cross platform, free, open source media encoder/decoder toolkit. It contains the programs and libraries necessary to convert audio and video into a wide range of formats. FFmpeg was written by Fabrice Bellard (creator of QEMU and BPG).

hardcoded-tables
|
Use pre-calculated tables rather than calculating them on the fly. It results in an increase of approximately 15% in the size of libavcodec, the main library impacted by this change. It enables savings in table generation time, done once at codec initialization, since by hardcoding the tables, they do not need to be computed at runtime. However, the savings are often negligible (~100k cycles is a typical number) especially when amortized over the entire encoding/decoding operation. Improvements are being made to the runtime initialization, and so over time, this option will have an impact on fewer and fewer codecs. |

The above list is non-comprehensive. Use equery (part of app-portage/gentoolkit) to see all available flags:
user $equery uses media-video/ffmpegEmerge
If not already pulled in as a dependency of other packages, and after setting appropriate USE flags, emerge FFmpeg:
root #emerge --ask media-video/ffmpegConfiguration
This section needs some help.
Usage
Media player (ffplay)
If built with USE=sdl, a command line media player called ffplay is available.
user $curl http://www.dradio.de/streaming/dlf_hq_ogg.m3u | xargs ffplayFor more information consult the following commands:
user $man 1 ffplayuser $ffplay -hSee also
