Jetpack libraries offer a richer feature set, more frequent updates, solutions for dealing with backwards-compatibility and fragmentation, and more customizability.\n\n- [Supported media formats](/guide/topics/media/platform/supported-formats): Learn about the media codecs, containers, formats, and network protocols supported by the Android platform.\n- [Compatible media transcoding](/guide/topics/media/platform/transcoding): Learn about the platform's ability to automatically convert videos recorded in modern video formats when opened by an app that doesn't support the format.\n- [MediaPlayer overview](/guide/topics/media/platform/mediaplayer): Learn about `MediaPlayer`, a platform API for audio and video playback.\n- [Control amplitude with VolumeShaper](/guide/topics/media/platform/volumeshaper): Learn about using the `VolumeShaper` API to perform short automated volume transitions such as fades and ducking.\n- [Handle changes in audio output](/guide/topics/media/platform/output): Learn about APIs for volume control and reacting to changes in the audio output device.\n- [Improve audio playback](/guide/topics/media/platform/improve-audio-playback#improve-audio-playback): Learn about using `DEFAULT` and `BIT_PERFECT` APIs to configure mixer attributes over USB.\n- [Share audio input](/guide/topics/media/platform/sharing-audio-input): Learn about capturing audio input from a mic or other input device.\n- [MediaRecorder overview](/guide/topics/media/platform/mediarecorder): Learn about using the `MediaRecorder` API to record audio.\n- [Capture video and audio playback](/guide/topics/media/platform/av-capture): Learn about using the `MediaProjection` and `AudioPlaybackCapture` APIs to record video or audio playback from another app, respectively."]]
