Transcodes and compresses video files into the MP4 format, with audio support, using hardware-accelerated Android codecs available on the device. Works on API 21+.

• Fast transcoding to AAC/AVC
• Hardware accelerated
• Convenient, fluent API
• Thumbnails support
• Concatenate multiple video and audio tracks [docs]
• Clip or trim video segments [docs]
• Choose output size, with automatic cropping [docs]
• Choose output rotation [docs]
• Choose output speed [docs]
• Choose output frame rate [docs]
• Choose output audio channels [docs]
• Choose output audio sample rate [docs]
• Override frames timestamp, e.g. to slow down the middle part of the video [docs]
• Error handling [docs]
• Configurable validators to e.g. avoid transcoding if the source is already compressed enough [docs]
• Configurable video and audio strategies [docs]

This project started as a fork of ypresto/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 options that 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 by ShareChat, a social media app with over 100 million downloads.

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