OVERVIEW

fmedia is a fast asynchronous media player/recorder/converter for Windows, Linux and FreeBSD. It provides smooth playback and recording even if devices are very slow. It's highly customizable and can be easily extended with additional plugins. Its low CPU & memory consumption saves energy when running on a notebook's battery.

Play or convert audio files, record new audio tracks from microphone, save songs from Internet radio, and much more! fmedia is free and open-source project, and you can use it as a standalone application or as a library for your own software.

fmedia can decode: .mp3, .ogg (Vorbis, Opus), .opus, .m4a/.mp4 (AAC, ALAC, MPEG), .mka/.mkv (AAC, ALAC, MPEG, Vorbis), .avi (AAC, MPEG), .aac, .mpc, .flac, .ape, .wv, .wav.

fmedia can encode into: .mp3, .ogg, .opus, .m4a (AAC), .flac, .wav.

Note: it's beta version - not tested well enough, not all functions will work as expected.

INSTALL

INSTALL ON WINDOWS

Unpack archive to the directory of your choice, e.g. to "C:\Program Files\fmedia"
- Right click on fmedia package file (e.g. fmedia-0.33-win-x64.zip) in Explorer
- Choose "Extract All..." in the popup menu
- Follow the Wizard steps
Optionally, run the following command from console (cmd.exe):
```
 "C:\Program Files\fmedia\fmedia.exe" --install
```
This command will:
- add fmedia directory into user's environment
- create a desktop shortcut to fmedia-gui.exe
Run fmedia-gui.exe to open graphical interface; or execute commands via fmedia.exe from console (cmd.exe).

INSTALL ON LINUX

Unpack archive to the directory of your choice, e.g. to /usr/local/fmedia-0:
```
 tar Jxf ./fmedia-0.33-linux-amd64.tar.xz -C /usr/local
```

Optionally, create a symbolic link:

 ln -s /usr/local/fmedia-0/fmedia /usr/local/bin/fmedia

BUILD ON LINUX

Create a directory for all needed sources:
```
 mkdir firmdev && cd firmdev
```

Download all needed source repositories:

 git clone https://github.com/stsaz/ffos
 git clone https://github.com/stsaz/ff
 git clone https://github.com/stsaz/ff-3pt
 git clone https://github.com/stsaz/fmedia

Build ff-3pt package (3rd-party libraries) or download pre-built binaries. See ff-3pt/README.txt for details.
Build fmedia:
```
 cd fmedia
 export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:../ff-3pt-bin/linux-amd64
 make install
```
You can explicitly specify path to each of FF source repositories, e.g.:
```
 make install FFOS=~/ffos FF=~/ff FF3PT=~/ff-3pt
```
Default architecture is amd64. You can specify different target architecture like this:
```
 make install ARCH=i686
```
You'll also need to specify the proper path to ff-3pt binaries in LD_LIBRARY_PATH.
Ready! You can copy the directory ./fmedia-0 anywhere you want (see section "INSTALL ON LINUX").

LIGHT BUILD

You can build fmedia without dependencies on 3rd-party libraries. This will be a very small package without audio (de)compression features. Follow these steps:

1-2. Repeat previously described steps.

Run this command:
```
 make install-nodeps
```
Edit fmedia.conf and manually remove all modules that require 3rd-party libraries.

BUILD ON LINUX FOR WINDOWS

1-3. See section "BUILD ON LINUX".

Build with mingw (64-bit):

 cd fmedia
 export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:../ff-3pt-bin/win-amd64
 mingw64-make OS=win CPREFIX=x86_64-w64-mingw32- install

Build with mingw (32-bit):

 cd fmedia
 export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:../ff-3pt-bin/win-i686
 mingw32-make OS=win ARCH=i686 CPREFIX=i686-w64-mingw32- install

Ready!

CONFIG

The global configuration file fmedia.conf is located within the fmedia directory itself. It contains all supported settings and their default values. You must restart fmedia after you make changes to this file.

Additional settings may be stored in file fmedia-ext.conf. This makes it easier to upgrade fmedia without the need to edit fmedia.conf.

Per-user configuration settings are also supported, they must be stored in fmedia-user.conf file in home directory:

Windows: %APPDATA%/fmedia/fmedia-user.conf
Linux:   $HOME/.config/fmedia/fmedia-user.conf

Settings for a module must be in format "so.module.key value", e.g. to overwrite the global setting for OGG Vorbis encoding quality you should write:

vorbis.encode.quality "7.0"

Core configuration settings start with "core.", e.g. set codepage for non-Unicode text:

core.codepage win1252

EXTRACT TRACKS FROM flac.cue

When you're extracting a track from the album in FLAC using CUE sheet, track is first decoded to PCM and then re-encoded with FLAC. This behaviour won't result in any audio quality loss since FLAC is a lossless codec.

TERMINAL UI

By default fmedia runs with a terminal UI, which shows information about the currently playing audio track and the currently playing audio position. User commands such as seeking are also supported, all supported commands are described in file "help-tui.txt".

GRAPHICAL UI

On Windows you can run fmedia in GUI mode:

fmedia-gui.exe

You should use this binary file for opening files via Explorer's "Open With..." feature.

Note: command-line options are not supported.

Or you may execute the console binary like this:

fmedia --gui

Note: GUI isn't supported on Linux.

fmedia GUI is provided by a separate module - gui.dll. It is written in such a way that it won't become unresponsive even if the main thread (the one that processes audio) is waiting for I/O operations. The module doesn't perform any sound processing, it just issues commands to fmedia core and receives the feedback.

fmedia GUI is highly customizable, thanks to FF library that is used under the hood. FF UI technology allows you to modify properties of every UI control: windows, buttons, menus, tray icons and more. You may resize controls, set different styling, change any text, hotkeys, etc. All this information is stored within "fmedia.gui" which is a plain text file. After you make some changes in fmedia.gui, save it and then restart fmedia.

By default fmedia GUI saves its state in file "%APPDATA%\fmedia\fmedia.gui.conf". You can change this by setting "portable_conf" to "true" in fmedia.conf. After that, "fmedia.gui.conf" will be stored in program directory (e.g. "C:\Program Files\fmedia\fmedia.gui.conf"), thus making fmedia completely portable.

USE-CASES

Note the difference between UNIX and Windows terminals when you use special characters and spaces:

Use single quotes ('') on Linux (sh, bash), e.g.:

  fmedia './my file.ogg'
  fmedia file.wav -o '$filename.ogg'

Use double quotes ("") on Windows (cmd.exe), e.g.:
```
  fmedia "./my file.ogg"
```

FOR DEVELOPERS

YOUR APPLICATION BASED ON FMEDIA

fmedia can be used as a sound library: you can freely use its abilities in your own software. And you don't have to build fmedia by yourself to use its features. All you need to do is link your binary file with core.so (or core.dll) and you'll be able to do everything that fmedia can: playback, record and convert audio from your application.

SUPPORT NEW FORMAT

You may add support for a new audio format into fmedia. To do that you have to add your module into "fmedia.conf" and add an appropriate file extension into "input_ext" or "output_ext" section.

For example, after you have built your module (e.g. xyz.so), add it into "fmedia.conf":

mod "xyz.decode"

Then associate it with ".xyz" file extension:

input_ext {
	...
	"xyz.decode" xyz
}

fmedia will call module "xyz.decode" each time user orders fmedia to play "*.xyz" files.

See fmedia source code for more details. For example, main.c::main() will show you how fmedia command line binary initializes core module. See acodec/wav.c for an example on how to write a simple filter for fmedia.

LOW-LEVEL INTERFACE

If you'd like to use low level interfaces, take a look at the source code of FF & FF-3pt libraries. Together they provide you with an easy interface that you can use to work with a large set of file formats, decode or encode audio and much more. fmedia itself is built upon FF library - it's completely free and open-source.

PARTICIPATE

You are welcome to participate in fmedia's development. Send suggestions, improvements, bug reports, patches - anything that can help the project!

Understanding the top-level source code hierarchy can help you to get involved into fmedia quicker. The source code consists of the 3 levels of these 4 separate repositories:

---------------
    fmedia
---------------
      FF
---------------
 FFOS | FF-3pt
---------------

Each of them plays its own part:

FFOS provides cross-platform abilities. Code based on FFOS can run on Windows, Linux and FreeBSD.
FF-3pt provides simple access to 3rd party libraries such as libFLAC.
FF contains all low/mid level interfaces that can be reused between different applications.
fmedia contains application code, it's largely based on all FF libraries.

BUG REPORT

If you encounter a bug, please report it: the more issues will be reported by users, the more stable fmedia will become. When filing a bug report try to provide information that can help us to fix the problem. Try to execute the same command once again, only this time add --debug switch, e.g.:

fmedia --debug OPTIONS INPUT_FILES...

It will print a lot of information about what fmedia is doing. This info or a screenshot would be very helpful.
