1## Media V2 CTS Tests 2Current 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. 3 4The 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. 5 6The test vectors used by the test suite is available at [link](https://dl.google.com/android/xts/cts/tests/media/CtsMediaV2TestCases-3.6.zip) and is downloaded automatically while running tests. Manual installation of these can be done using copy_media.sh script in this directory. 7 8All Big Buck Bunny(bbb) test vectors are of 8-bit format. They are downloaded from [link](https://peach.blender.org/download/) and resampled according to the test requirements. 9All Cosmos Laundromat(cosmat) test vectors are of 10-bit format. They are downloaded from [link](https://media.xiph.org/) and resampled according to the test requirements. 10 11The 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, ...). 12 13### Commands 14```sh 15$ atest android.mediav2.cts 16$ atest android.mediav2.cts.CodecEncoderTest android.mediav2.cts.CodecDecoderTest 17$ atest android.mediav2.cts.MuxerTest android.mediav2.cts.MuxerUnitTest 18$ atest android.mediav2.cts.ExtractorTest android.mediav2.cts.ExtractorUnitTest 19``` 20 21### Features 22All tests accepts attributes that offer selective run of tests. 23 24#### Select codecs by name 25To 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. 26 27Example: To limit the tests to run for codecs whose names start with c2.android. 28 29```sh 30atest CtsMediaV2TestCases -- --module-arg CtsMediaV2TestCases:instrumentation-arg:codec-prefix:=c2.android. 31``` 32 33Example: To limit the tests to run for c2.android.hevc.decoder 34 35```sh 36atest CtsMediaV2TestCases -- --module-arg CtsMediaV2TestCases:instrumentation-arg:codec-prefix:=c2.android.hevc.decoder 37``` 38 39#### Select codecs by type 40To select codecs by type, *media-type-sel* can be passed to media codec tests to select one or more codecs. 41 42Example: To limit media codec decoder tests to mp3 and vorbis decoder 43 44```sh 45atest android.mediav2.cts.CodecDecoderTest -- --module-arg CtsMediaV2TestCases:instrumentation-arg:media-type-sel:=mp3,vorbis 46``` 47 48#### Select extractors by type 49To select extractors by type, *ext-sel* can be passed to extractor tests to select one or more extractors. 50 51Example: To limit extractor tests to mp4 and webm types 52```sh 53atest android.mediav2.cts.ExtractorTest -- --module-arg CtsMediaV2TestCases:instrumentation-arg:ext-sel:=mp4,webm 54``` 55 56#### Select muxers by type 57To select muxers by type, *mux-sel* can be passed to muxer tests to select one or more muxers. 58 59Example: To limit muxer tests to mp4 and webm types 60```sh 61atest android.mediav2.cts.MuxerTest -- --module-arg CtsMediaV2TestCases:instrumentation-arg:mux-sel:=mp4,webm 62``` 63 64### Appendix 65| Identifier for codec-sel | Mime | 66| ------ | ------ | 67|default|all| 68|vp8|mimetype_video_vp8| 69|vp9|mimetype_video_vp9| 70|av1|mimetype_video_av1| 71|avc|mimetype_video_avc| 72|hevc|mimetype_video_hevc| 73|mpeg4|mimetype_video_mpeg4| 74|h263|mimetype_video_h263| 75|mpeg2|mimetype_video_mpeg2| 76|vraw|mimetype_video_raw| 77|amrnb|mimetype_audio_amr_nb| 78|amrwb|mimetype_audio_amr_wb| 79|mp3|mimetype_audio_mpeg| 80|aac|mimetype_audio_aac| 81|vorbis|mimetype_audio_vorbis| 82|opus|mimetype_audio_opus| 83|g711alaw|mimetype_audio_g711_alaw| 84|g711mlaw|mimetype_audio_g711_mlaw| 85|araw|mimetype_audio_raw| 86|flac|mimetype_audio_flac| 87|gsm|mimetype_audio_msgsm| 88 89 90| Identifier for ext-sel | Extractor format | 91| ------ | ------ | 92|mp4|Mpeg4| 93|webm|Matroska| 94|3gp|Mpeg4| 95|mkv|Matroska| 96|ogg|Ogg| 97 98 99| Identifier for mux-sel | Muxer Format | 100| ------ | ------ | 101|mp4|muxer_output_mpeg4| 102|webm|muxer_output_webm| 103|3gp|muxer_output_3gpp| 104|ogg|muxer_output_ogg| 105
