2. Building

Run ios.sh/macos.sh/tvos.sh inside the project root to build ffmpeg-kit and ffmpeg shared libraries for a platform.

Optionally, use apple.sh to combine bundles created by these three scripts in a single bundle.

Please note that FFmpegKit project repository includes the source code of FFmpegKit only. ios.sh, macos.sh and tvos.sh need network connectivity and internet access to github.com in order to download the source code of FFmpeg and external libraries enabled.

2.1 Prerequisites

ios.sh, macos.sh and tvos.sh require the following tools and packages.

2.1.1 iOS

Xcode 8.0 or later
iOS SDK 10 or later
Command Line Tools

2.1.2 macOS

Xcode 8.0 or later
macOS SDK 10.12 or later
Command Line Tools

2.1.3 tvOS

Xcode 8.0 or later
tvOS SDK 10.0 or later
Command Line Tools

2.1.4 Packages

Use your package manager (brew, etc.) to install the following packages.

autoconf automake libtool pkg-config curl git doxygen nasm cmake gcc gperf texinfo yasm bison autogen wget gettext meson ninja ragel groff gtk-doc-tools libtasn1

2.2 Options

Use --enable-<library name> flag to support additional external or system libraries and --disable-<architecture name> to disable architectures you don't want to build.

./ios.sh --enable-fontconfig --disable-armv7

3. Using

3.1 Objective API

Add FFmpegKit dependency to your Podfile in ffmpeg-kit-<platform>-<package name> pattern. Use one of the FFmpegKit package names given in the project README.
- iOS
```
pod 'ffmpeg-kit-ios-full', '~> 6.0'
```
- macOS
```
pod 'ffmpeg-kit-macos-full', '~> 6.0'
```
- tvOS
```
pod 'ffmpeg-kit-tvos-full', '~> 6.0'
```

Execute synchronous FFmpeg commands.

#include <ffmpegkit/FFmpegKit.h>

FFmpegSession *session = [FFmpegKit execute:@"-i file1.mp4 -c:v mpeg4 file2.mp4"];
ReturnCode *returnCode = [session getReturnCode];
if ([ReturnCode isSuccess:returnCode]) {

    // SUCCESS

} else if ([ReturnCode isCancel:returnCode]) {

    // CANCEL

} else {

    // FAILURE
    NSLog(@"Command failed with state %@ and rc %@.%@", [FFmpegKitConfig sessionStateToString:[session getState]], returnCode, [session getFailStackTrace]);

}

Each execute call (sync or async) creates a new session. Access every detail about your execution from the session created.

FFmpegSession *session = [FFmpegKit execute:@"-i file1.mp4 -c:v mpeg4 file2.mp4"];

// Unique session id created for this execution
long sessionId = [session getSessionId];

// Command arguments as a single string
NSString *command = [session getCommand];

// Command arguments
NSArray *arguments = [session getArguments];

// State of the execution. Shows whether it is still running or completed
SessionState state = [session getState];

// Return code for completed sessions. Will be null if session is still running or ends with a failure
ReturnCode *returnCode = [session getReturnCode];

NSDate *startTime =[session getStartTime];
NSDate *endTime =[session getEndTime];
long duration =[session getDuration];

// Console output generated for this execution
NSString *output = [session getOutput];

// The stack trace if FFmpegKit fails to run a command
NSString *failStackTrace = [session getFailStackTrace];

// The list of logs generated for this execution
NSArray *logs = [session getLogs];

// The list of statistics generated for this execution
NSArray *statistics = [session getStatistics];

Execute asynchronous FFmpeg commands by providing session specific execute/log/session callbacks.

FFmpegSession* session = [FFmpegKit executeAsync:@"-i file1.mp4 -c:v mpeg4 file2.mp4" withCompleteCallback:^(FFmpegSession* session){
    SessionState state = [session getState];
    ReturnCode *returnCode = [session getReturnCode];

    // CALLED WHEN SESSION IS EXECUTED

    NSLog(@"FFmpeg process exited with state %@ and rc %@.%@", [FFmpegKitConfig sessionStateToString:state], returnCode, [session getFailStackTrace]);

} withLogCallback:^(Log *log) {

    // CALLED WHEN SESSION PRINTS LOGS

} withStatisticsCallback:^(Statistics *statistics) {

    // CALLED WHEN SESSION GENERATES STATISTICS

}];

Execute FFprobe commands.

Synchronous

FFprobeSession *session = [FFprobeKit execute:ffprobeCommand];

if ([ReturnCode isSuccess:[session getReturnCode]]) {
    NSLog(@"Command failed. Please check output for the details.");
}

Asynchronous

[FFprobeKit executeAsync:ffmpegCommand withCompleteCallback:^(FFprobeSession* session) {

    CALLED WHEN SESSION IS EXECUTED

}];

Get media information for a file.

MediaInformationSession *mediaInformation = [FFprobeKit getMediaInformation:"<file path or uri>"];
MediaInformation *mediaInformation =[mediaInformation getMediaInformation];

Stop ongoing FFmpeg operations.
- Stop all executions
```
[FFmpegKit cancel];
```
- Stop a specific session
```
[FFmpegKit cancel:sessionId];
```

Get previous FFmpeg and FFprobe sessions from session history.

NSArray* sessions = [FFmpegKitConfig getSessions];
for (int i = 0; i < [sessions count]; i++) {
    id<Session> session = [sessions objectAtIndex:i];
    NSLog(@"Session %d = id: %ld, startTime: %@, duration: %ld, state:%@, returnCode:%@.\n",
        i,
        [session getSessionId],
        [session getStartTime],
        [session getDuration],
        [FFmpegKitConfig sessionStateToString:[session getState]],
        [session getReturnCode]);
}

Enable global callbacks.

Session type specific Complete Callbacks, called when an async session has been completed

[FFmpegKitConfig enableFFmpegSessionCompleteCallback:^(FFmpegSession* session) {
    ...
}];

[FFmpegKitConfig enableFFprobeSessionCompleteCallback:^(FFprobeSession* session) {
    ...
}];

[FFmpegKitConfig enableMediaInformationSessionCompleteCallback:^(MediaInformationSession* session) {
    ...
}];

Log Callback, called when a session generates logs

[FFmpegKitConfig enableLogCallback:^(Log *log) {
    ...
}];

Statistics Callback, called when a session generates statistics

[FFmpegKitConfig enableStatisticsCallback:^(Statistics *statistics) {
    ...
}];

Ignore the handling of a signal. Required by Mono and frameworks that use Mono, e.g. Unity and Xamarin.
```
[FFmpegKitConfig ignoreSignal:SIGXCPU];
```

Register system fonts and custom font directories.

[FFmpegKitConfig setFontDirectoryList:[NSArray arrayWithObjects:@"/System/Library/Fonts", @"<folder with fonts>", nil] with:nil];

4. Test Application

You can see how FFmpegKit is used inside an application by running iOS, macOS and tvOS test applications developed under the FFmpegKit Test project.
