3Device implementations:
4
5*   [C-0-1] MUST support the media formats, encoders, decoders, file types,
6    and container formats defined in [section 5.1](#5_1_media-codecs.md)
7    for each and every codec declared by `MediaCodecList`.
8*   [C-0-2] MUST declare and report support of the encoders, decoders available
9    to third-party applications via [`MediaCodecList`](
10    http://developer.android.com/reference/android/media/MediaCodecList.html).
11*   [C-0-3] MUST be able to decode and make available to third-party apps all
12    the formats it can encode. This includes all bitstreams that its encoders
13    generate and the profiles reported in its [`CamcorderProfile`](
14    http://developer.android.com/reference/android/media/CamcorderProfile.html).

17Device implementations:
18
19*   SHOULD aim for minimum codec latency, in others words, they
20    *   SHOULD NOT consume and store input buffers and return input buffers only
21    once processed.
22    *   SHOULD NOT hold onto decoded buffers for longer than as specified by the
23    standard (e.g. SPS).
24    *   SHOULD NOT hold onto encoded buffers longer than required by the GOP
25    structure.

28implementations in the preferred Android implementation from the Android Open
