Media V2 CTS Tests

Current folder comprises of files necessary for testing media extractor, media muxer, media codec SDK and NDK Api. These tests aims to test all codecs advertised in MediaCodecList, available muxers and extractors.

The aim of these tests is not solely to verify the CDD requirements but also to test components, their plugins and their interactions with media framework.

The test vectors used by the test suite is available at link and is downloaded automatically while running tests. Manual installation of these can be done using copy_media.sh script in this directory.

The test suite looks to cover sdk/ndk api in normal and error scenarios. Error scenarios are separated from regular usage and are placed under class *UnitTest (MuxerUnitTest, ExtractorUnitTest, ...).

Commands

$ atest android.mediav2.cts
$ atest android.mediav2.cts.CodecEncoderTest android.mediav2.cts.CodecDecoderTest
$ atest android.mediav2.cts.MuxerTest android.mediav2.cts.MuxerUnitTest
$ atest android.mediav2.cts.ExtractorTest android.mediav2.cts.ExtractorUnitTest

Features

All tests accepts attributes that offer selective run of tests. Media codec tests parses the value of key codec-sel to determine the list of components on which the tests are to be tried. Similarly for Media extractor and media muxer parses the value of keys ext-sel and mux-sel to determine the list of components on which the tests are to be tried.

To limit media codec decoder tests to mp3 and vorbis decoder,

adb shell am instrument -w -r  -e codec-sel 'mp3;vorbis'  -e debug false -e class 'android.mediav2.cts.CodecDecoderTest' android.mediav2.cts.test/androidx.test.runner.AndroidJUnitRunner
