This gets rid of the reliance on the decode only flag that is still set on input buffers to the decoder if they are less than the start time. We still need to set and check the decode-only flag in SimpleDecoder to ensure compatbility with custom decoders that use the flag while it's not fully removed. PiperOrigin-RevId: 570736692
MIDI decoder module
The MIDI module provides MidiExtractor for parsing standard MIDI files, and
MidiRenderer which uses the audio synthesization library JSyn to process
MIDI commands and render the PCM output.
Getting the module
The easiest way to get the module is to add it as a gradle dependency:
implementation 'androidx.media3:lib-decoder-midi:1.X.X'
where 1.X.X is the version, which must match the version of the other media
modules being used.
Alternatively, you can clone this GitHub project and depend on the module locally. Instructions for doing this can be found in the top level README.
The module depends on JSyn as a maven dependency from jitpack.io and you will need to define the maven repository in your build scripts. For example, add
repositories {
maven { url 'https://jitpack.io' }
}
in the build.gradle of module in your app that is using the MIDI module.
Use in the demo app
Modify the demo app's build.script file and uncomment the definition of the
jitpack.io maven repository, as well as uncomment the dependency to the MIDI
module in the dependencies section.
