# 5\. Multimedia Compatibility

|
|
Device implementations:
|
|
|
|
* [C-0-1] MUST support the media formats, encoders, decoders, file types,
|
|
and container formats defined in [section 5.1](#5_1_media-codecs.md)
|
|
for each and every codec declared by `MediaCodecList`.
|
|
* [C-0-2] MUST declare and report support of the encoders, decoders available
|
|
to third-party applications via [`MediaCodecList`](
|
|
http://developer.android.com/reference/android/media/MediaCodecList.html).
|
|
* [C-0-3] MUST be able to properly decode and make available to third-party
|
|
apps all the formats it can encode. This includes all bitstreams that its
|
|
encoders generate and the profiles reported in its [`CamcorderProfile`](
|
|
http://developer.android.com/reference/android/media/CamcorderProfile.html).
|
|
|
|
Device implementations:
|
|
|
|
* SHOULD aim for minimum codec latency, in others words, they
|
|
* SHOULD NOT consume and store input buffers and return input buffers only
|
|
once processed.
|
|
* SHOULD NOT hold onto decoded buffers for longer than as specified by the
|
|
standard (e.g. SPS).
|
|
* SHOULD NOT hold onto encoded buffers longer than required by the GOP
|
|
structure.
