-=================
+# Transcoder
 
-Hardware accelerated transcoder for Android, written in pure Java.
-
-## Why?
-
-Android does not offer straight forward way to transcode video.
-
-FFmpeg is the most famous solution for transcoding. But using [FFmpeg binary on Android](https://github.com/WritingMinds/ffmpeg-android) can cause GPL and/or patent issues. Also using native code for Android development can be troublesome because of cross-compiling, architecture compatibility, build time and binary size.
-
-To transcode without any hassle written above, I created this library to provide hardware accelerated transcoding of H.264 (mp4) video without ffmpeg by using [MediaCodec](https://developer.android.com/intl/ja/reference/android/media/MediaCodec.html).
-
-## Requirements
-
-API Level 18 (Android 4.3, JELLY_BEAN_MR2) or later.
-If your app targets older Android, you should add below line to AndroidManifest.xml:
-
-```xml
-<!-- Only supports API >= 18 -->
-<uses-sdk tools:overrideLibrary="net.ypresto.androidtranscoder" />
-```
-
-Please ensure checking Build.VERSION by your self.
-
-## Usage
-
-```java
-@Override
-protected void onActivityResult(int requestCode, int resultCode, Intent data) {
-    ParcelFileDescriptor parcelFileDescriptor = resolver.openFileDescriptor(data.getData(), "r");
-    FileDescriptor fileDescriptor = parcelFileDescriptor.getFileDescriptor();
-    MediaTranscoder.Listener listener = new MediaTranscoder.Listener() {
-        @Override
-        public void onTranscodeProgress(double progress) {
-            ...
-        }
-
-        @Override
-        public void onTranscodeCompleted() {
-            startActivity(new Intent(Intent.ACTION_VIEW).setDataAndType(Uri.fromFile(file), "video/mp4"));
-            ...
-        }
-
-        @Override
-        public void onTranscodeFailed(Exception exception) {
-            ...
-        }
-    };
-    MediaTranscoder.getInstance().transcodeVideo(fileDescriptor, file.getAbsolutePath(),
-            MediaFormatStrategyPresets.createAndroid720pStrategy(), listener); // or createAndroid720pStrategy([your bitrate here])
-}
-```
-
-See `TranscoderActivity.java` in example directory for ready-made transcoder app.
-
-## Quick Setup
-
-### Gradle
-
-Available from [JCenter](https://bintray.com/bintray/jcenter), which is default repo of gradle script generated by recent android studio.
-
-```groovy
-repositories {
-   jcenter()
-}
-```
+This project is an improved fork of [ypresto/android-transcoder](https://github.com/ypresto/android-transcoder).
+Lots of changes were made, so the documentation must be rewritten. You can, however, take a look at the
+demo app which provides a working example of the new API.
 
 ```groovy
-compile 'net.ypresto.androidtranscoder:android-transcoder:0.2.0'
+implementation 'com.otaliastudios:transcoder:0.4.0'
 ```
 
-## Note (PLEASE READ FIRST)
+## Setup
 
-- This library raises `RuntimeException`s (like `IlleagalStateException`) in various situations. Please catch it and provide alternate logics. I know this is bad design according to Effective Java; just is TODO.
-- Currently this library does not generate streaming-aware mp4 file.
-Use [qtfaststart-java](https://github.com/ypresto/qtfaststart-java) to place moov atom at beginning of file.
-- Android does not gurantees that all devices have bug-free codecs/accelerators for your codec parameters (especially, resolution). Refer [supported media formats](http://developer.android.com/guide/appendix/media-formats.html) for parameters guaranteed by [CTS](https://source.android.com/compatibility/cts-intro.html).
-- This library does not support video files recorded by other device like digital cameras, iOS (mov files, including non-baseline profile h.264), etc.
+This library requires API level 18 (Android 4.3, JELLY_BEAN_MR2) or later.
+If your app targets older versions, you can override the minSdkVersion by
+adding this line to your manifest file:
 
+```xml
+<uses-sdk tools:overrideLibrary="com.otaliastudios.transcoder" />
+```
 
-## More information about internals
-
-There is a blog post about this library written in Japanese.
-http://qiita.com/yuya_presto/items/d48e29c89109b746d000
-
-While it is Japanese, diagrams would be useful for understanding internals of this library.

-- https://github.com/google/grafika
-- https://android.googlesource.com/platform/frameworks/av/+/lollipop-release/media/libstagefright
+In this case you should check at runtime that API level is at least 18, before
+calling any method here.
