This project started as a fork ofypresto/android-transcoder.With respect to the source project, which misses most of the functionality listed above,we have also fixed a huge number of bugs and are much less conservative when choosing optionsthat might not be supported. The source project will always throw - for example, accepting only 16:9,AVC Baseline Profile videos - we prefer to try and let the codec fail if it wants to.

Transcoder is trusted and supported byShareChat, a social media app withover 100 million downloads.

Please check outthe official website for setup instructions and documentation.You may also check the demo app (under/demo) for a complete example.
