Media Performance Class CTS Tests

Current folder comprises of files necessary for testing media performance class.

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.

Commands

To run all tests in CtsMediaPerformanceClassTestCases

$ atest CtsMediaPerformanceClassTestCases

To run a subset of tests in CtsMediaPerformanceClassTestCases

$ atest CtsMediaPerformanceClassTestCases:android.mediapc.cts.FrameDropTest

To run all tests in CtsMediaPerformanceClassTestCases by overriding Build.VERSION.MEDIA_PERFORMANCE_CLASS

In some cases it might be useful to override Build.VERSION.MEDIA_PERFORMANCE_CLASS and run the tests. For eg: when the device doesn't advertise Build.VERSION.MEDIA_PERFORMANCE_CLASS, running the tests by overriding this will help in determining the which performance class requirements are met by the device. Following runs the tests by overriding Build.VERSION.MEDIA_PERFORMANCE_CLASS as S.

$ atest CtsMediaPerformanceClassTestCases -- --module-arg CtsMediaPerformanceClassTestCases:instrumentation-arg:media-performance-class:=31

Features

All tests accepts attributes that offer selective run of tests.

Select codecs by media type

To select codecs by media type, media-type-prefix can be passed to media codec tests to select one or more codecs that start with a given prefix.

Example: To limit the tests to run for media types whose names start with video/avc

atest CtsMediaPerformanceClassTestCases -- --module-arg CtsMediaPerformanceClassTestCases:instrumentation-arg:media-type-prefix:=video/avc

Select codecs using regular expressions

To select codecs by applying regular expressions, codec-filter can be passed to media codec tests to select one or more codecs that match with a specified regular expression pattern.

Example: To limit the tests to run for c2.android.avc.decoder and c2.android.hevc.encoder

atest CtsMediaPerformanceClassTestCases -- --module-arg CtsMediaPerformanceClassTestCases:instrumentation-arg:codec-filter:="c2\.android\.avc\.decoder\|c2\.android\.hevc\.encoder"

Select codecs by name

To select codecs by name, codec-prefix can be passed to media codec tests to select one or more codecs that start with a given prefix.

Example: To limit the tests to run for codecs whose names start with c2.android.

atest CtsMediaPerformanceClassTestCases -- --module-arg CtsMediaPerformanceClassTestCases:instrumentation-arg:codec-prefix:=c2.android.

Example: To limit the tests to run for c2.android.hevc.decoder

atest CtsMediaPerformanceClassTestCases -- --module-arg CtsMediaPerformanceClassTestCases:instrumentation-arg:codec-prefix:=c2.android.hevc.decoder
