When sample batching is disabled, copying of the ByteBuffer data is not necessary as samples are written as they arrive. Copying of the BufferInfo is necessary because the info is needed for writing the moov atom. The input ByteBuffer can be in little endian order, or have its position set. AnnexBUtils now ensures big endian order before inspecting bytes, and supports reading from a non-zero position. This change reduces the amount of memory allocations by Mp4Muxer in its default configuration PiperOrigin-RevId: 723401822
Muxer module
Provides functionality for producing media container files.
Getting the module
The easiest way to get the module is to add it as a gradle dependency:
implementation 'androidx.media3:media3-muxer: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.
