fmedia - fast media player/recorder/converter


fmedia is a fast asynchronous media player/recorder/converter for Windows and Linux. Its goal is to provide smooth playback even if input device is very slow and unresponsive. The architecure allows to extend the functionality of the application in any way: adding a new audio input/output format, a new DSP filter or even a new GUI. fmedia is very small and fast: it has low CPU & memory consumption making it ideal to listen to music or process audio files while running on a notebook's battery. fmedia can decode: .mp3, .ogg, .m4a/.mp4 (AAC, ALAC), .flac, .ape, .wv, .wav. fmedia can encode into: .mp3, .ogg, .m4a (AAC), .flac, .wav. You'll find more detailed information about fmedia in README.txt file inside the package.


Note: it's beta version - not tested well enough, not all functions will work as expected. See section "USE-CASES" to have an idea of which features should work.

Self-contained. fmedia uses modified versions of 3rd party libraries: libALAC, libfdk-aac, libFLAC, libMAC, libmp3lame, libmpg123, libogg, libsoxr, libvorbisenc, libvorbis, libwavpack. Everything is inside the package, so no additional dependencies are required to be installed on your system.

Portable. No installation, just uncompress the package anywhere you want!

Open-source. You can download the sourcecode from here:

fmedia v0.17 - Oct 3, 2016
 * GUI: move playlist menu items from File to List
 * GUI convert: add "stream_copy" setting
 - GUI: support DPI settings for listview columns width
 - GUI: volume setting wasn't active on the first audio data (v0.16 bug)

 * MP4 write: write bitrate value into esds box
 + MP4 write: write trackno/tracktotal
 + MP4/AAC write: preallocate output space
 + MPEG write: preallocate output space
 - MPEG stream copy: fix double Xing tags
 - MPEG read: fix invalid current sample number by accounting for encoder/decoder delays
 - PCM int24, FLAC write: fix invalid negative 24-bit integer handling
 - WAV read: fix bad PCM format parse from wave file with extended header (FF v16.08 bug)
 + ALSA out: add config setting "notify_rate"

 - queue: fix segfault on stopping track whose playlist has been closed before
 + file read: "direct_io" config setting
 * file write: preallocation size can grow as output file grows
 * file write: delete file if an error has occurred in track chain
 - core: module data could be initialized twice, resulting in mem leak and slower startup time

1. Unpack archive to the directory of your choice, e.g. to "C:\Program Files\fmedia" 2. Optionally, add the path into the system environment:

set PATH=%PATH%;C:\Program Files\fmedia


1. Unpack archive to the directory of your choice, e.g. to "/usr/local/fmedia-0":

tar Jxf ./fmedia-0.8-linux-amd64.tar.xz -C /usr/local
2. Optionally, create a symbolic link:
ln -s /usr/local/fmedia-0/fmedia /usr/local/bin/fmedia
Note: the file "fmedia-0/fmedia" is just a script that executes binary file "fmedia-0/fmedia-bin" with proper environment. If the script doesn't work for some reason, call fmedia-bin directly:
env LD_LIBRARY_PATH=$LD_LIBRARY_PATH:/usr/local/fmedia-0 /usr/local/fmedia-0/fmedia-bin
