4
5See more details in [5.1.3. Audio Codecs Details](#5_1_3_audio_codecs_details).
6
7If device implementations declare `android.hardware.microphone`,
8they MUST support encoding the following audio formats and make them available
9to third-party apps:
10
11*    [C-1-1] PCM/WAVE
12*    [C-1-2] FLAC
13*    [C-1-3] Opus
14
15All audio encoders MUST support:
16
17*  [C-3-1] PCM 16-bit native byte order audio frames via the [`android.media.MediaCodec`](
18https://developer.android.com/reference/android/media/MediaCodec.html#raw-audio-buffers)
19API.

22### 5.1.2\. Audio Decoding
23
24See more details in [5.1.3. Audio Codecs Details](#5_1_3_audio_codecs_details).
25
26
27If device implementations declare support for the
28`android.hardware.audio.output` feature, they must support decoding the
29following audio formats:
30
31*    [C-1-1] MPEG-4 AAC Profile (AAC LC)
32*    [C-1-2] MPEG-4 HE AAC Profile (AAC+)
33*    [C-1-3] MPEG-4 HE AACv2 Profile (enhanced AAC+)
34*    [C-1-4] AAC ELD (enhanced low delay AAC)
35*    [C-1-11] xHE-AAC (ISO/IEC 23003-3 Extended HE AAC Profile, which includes
36             the USAC Baseline Profile, and ISO/IEC 23003-4 Dynamic Range
37             Control Profile)
38*    [C-1-5] FLAC
39*    [C-1-6] MP3
40*    [C-1-7] MIDI
41*    [C-1-8] Vorbis
42*    [C-1-9] PCM/WAVE including high-resolution audio
43formats up to 24 bits, 192 kHz sample rate, and 8 channels.
44Note that this requirement is for decoding only, and that a device
45is permitted to downsample and downmix during the playback phase.
46*    [C-1-10] Opus
47
48If device implementations support the decoding of AAC input buffers of
49multichannel streams (i.e. more than two channels) to PCM through the default
50AAC audio decoder in the `android.media.MediaCodec` API, the following MUST be
51supported:
52
53*    [C-2-1] Decoding MUST be performed without downmixing (e.g. a 5.0 AAC
54stream must be decoded to five channels of PCM, a 5.1 AAC stream must be decoded
55to six channels of PCM).
56*    [C-2-2] Dynamic range metadata MUST be as defined in "Dynamic Range Control
57(DRC)" in ISO/IEC 14496-3, and the `android.media.MediaFormat` DRC keys to
58configure the dynamic range-related behaviors of the audio decoder. The
59AAC DRC keys were introduced in API 21, and are:
60`KEY_AAC_DRC_ATTENUATION_FACTOR`, `KEY_AAC_DRC_BOOST_FACTOR`,
61`KEY_AAC_DRC_HEAVY_COMPRESSION`, `KEY_AAC_DRC_TARGET_REFERENCE_LEVEL` and
62`KEY_AAC_ENCODED_TARGET_LEVEL`.
63*    [SR] It is STRONGLY RECOMMENDED that requirements C-2-1 and C-2-2 above are
64satisfied by all AAC audio decoders.
65
66When decoding USAC audio, MPEG-D (ISO/IEC 23003-4):
67
68*    [C-3-1] Loudness and DRC metadata MUST be interpreted and applied
69according to MPEG-D DRC Dynamic Range Control Profile Level 1.
70*    [C-3-2] The decoder MUST behave according to the configuration
71set with the following `android.media.MediaFormat` keys:
72`KEY_AAC_DRC_TARGET_REFERENCE_LEVEL` and `KEY_AAC_DRC_EFFECT_TYPE`.
73
74MPEG-4 AAC, HE AAC, and HE AACv2 profile decoders:
75
76*    MAY support loudness and dynamic range control using ISO/IEC 23003-4
77Dynamic Range Control Profile.
78
79If ISO/IEC 23003-4 is supported and if both ISO/IEC 23003-4 and
80ISO/IEC 14496-3 metadata are present in a decoded bitstream, then:
81
82*    ISO/IEC 23003-4 metadata SHALL take precedence.
83
84All audio decoders MUST support outputting:
85
86*  [C-6-1] PCM 16-bit native byte order audio frames via the [`android.media.MediaCodec`](
87https://developer.android.com/reference/android/media/MediaCodec.html#raw-audio-buffers)
88API.

330
331*   For acceptable quality of web video streaming and video-conference
332services, device implementations SHOULD use a hardware VP8 codec that meets the
333[requirements](http://www.webmproject.org/hardware/rtc-coding-requirements/).
334

336
337*   [C-1-1] Video codecs MUST support output and input bytebuffer sizes that
338accommodate the largest feasible compressed and uncompressed frame as dictated
339by the standard and configuration but also not overallocate.

377format key, video decoder implementations:
378
379*   [C-4-1] MUST default to the color format optimized for hardware display
380if configured using Surface output.
381*   [C-4-2] MUST default to a YUV420 8:8:8 color format optimized for CPU

456### 5.1.9\. Media Codec Security
457
458Device implementations MUST ensure compliance with media codec security features
459as described below.
460
461Android includes support for OMX, a cross-platform multimedia acceleration API,
462as well as Codec 2.0, a low-overhead multimedia acceleration API.
463
464If device implementations support multimedia, they:
465
466*   [C-1-1] MUST provide support for media codecs either via OMX or Codec 2.0
467APIs (or both) as in the Android Open Source Project and not disable or
468circumvent the security protections. This specifically does not mean that every
469codec MUST use either the OMX or Codec 2.0 API, only that support for at least
470one of these APIs MUST be available, and support for the available APIs MUST
471include the security protections present.
472*   [C-SR] Are STRONGLY RECOMMENDED to include support for Codec 2.0 API.
473
474If device implementations do not support the Codec 2.0 API, they:
475
476*   [C-2-1] MUST include the corresponding OMX software codec from the Android
477Open Source Project (if it is available) for each media format and type
478(encoder or decoder) supported by the device.
479*   [C-2-2] Codecs that have names starting with "OMX.google." MUST be based
480on their Android Open Source Project source code.
481*   [C-SR]  Are STRONGLY RECOMMENDED that the OMX software codecs run in a codec
482process that does not have access to hardware drivers other than memory mappers.
483
484If device implementations support Codec 2.0 API, they:
485
486*   [C-3-1] MUST include the corresponding Codec 2.0 software codec from the
487Android Open Source Project (if it is available) for each media format and type
488(encoder or decoder) supported by the device.
489*   [C-3-2] MUST house the Codec 2.0 software codecs in the software codec
490process as provided in the Android Open Source Project to make it possible
491to more narrowly grant access to software codecs.
492*   [C-3-3] Codecs that have names starting with "c2.android." MUST be based
493on their Android Open Source Project source code.
494
495### 5.1.10\. Media Codec Characterization
496
497If device implementations support media codecs, they:
498
499*  [C-1-1] MUST return correct values of media codec characterization via the
500   [`MediaCodecInfo`](
501   https://developer.android.com/reference/android/media/MediaCodecInfo)
502   API.
503
504In particular:
505
506*  [C-1-2] Codecs with names starting with "OMX." MUST use the OMX APIs
507and have names that conform to OMX IL naming guidelines.
508*  [C-1-3] Codecs with names starting with "c2." MUST use the Codec 2.0 API and
509have names that conform to Codec 2.0 naming guidelines for Android.
510*  [C-1-4] Codecs with names starting with "OMX.google." or "c2.android." MUST
511NOT be characterized as vendor or as hardware-accelerated.
512*  [C-1-5] Codecs that run in a codec process (vendor or system) that have
513access to hardware drivers other than memory allocators and mappers MUST NOT
514be characterized as software-only.
515*  [C-1-6] Codecs not present in the Android Open Source Project or not based
516on the source code in that project MUST be characterized as vendor.
517*  [C-1-7] Codecs that utilize hardware acceleration MUST be characterized
518as hardware accelerated.
519*  [C-1-8] Codec names MUST NOT be misleading. For example, codecs named
520"decoders" MUST support decoding, and those named "encoders" MUST support
521encoding. Codecs with names containing media formats MUST support those
522formats.
523
524If device implementations support video codecs:
525
526*  [C-2-1] All video codecs MUST publish achievable frame rate data for the
527following sizes if supported by the codec:

561*  [C-2-2] Video codecs that are characterized as hardware accelerated MUST
562publish performance points information. They MUST each list all supported
563standard performance points (listed in [`PerformancePoint`](
564https://developer.android.com/reference/android/media/MediaCodecInfo.VideoCapabilities)
565API), unless they are covered by another supported standard performance point.
566*  Additionally they SHOULD publish extended performance points if they
567support sustained video performance other than one of the standard ones listed.
