muxer-tracks

Overview ¶

Muxer track format preparation example.

Demonstrates how to build AMediaFormat objects for audio and video tracks using the chaining API, query properties back with GetInt32, and documents how these formats feed into the AMediaMuxer track-addition workflow.

The muxer itself requires a valid file descriptor and encoded media data, so this example focuses on the format construction and property verification steps that precede muxing. The muxer workflow is documented in comments.

This program must run on an Android device with NDK media support.
