EncoderProfiles
class EncoderProfiles
kotlin.Any | |
↳ | android.media.EncoderProfiles |
Describes a set of encoding profiles for a given media (audio and/or video) profile. These settings are read-only.
Currently, this is used to describe camera recording profile with more detail than CamcorderProfile
, by providing encoding parameters for more than just the default audio and/or video codec.
The compressed output from a camera recording session contains two tracks: one for audio and one for video.
In the future audio-only recording profiles may be defined.
Each media profile specifies a set of audio and a set of video specific settings.
- The file output format
- Default file duration
Video-specific settings are:
- Video codec format
- Video bit rate in bits per second
- Video frame rate in frames per second
- Video frame width and height,
- Video encoder profile.
Audio-specific settings are:
- Audio codec format
- Audio bit rate in bits per second,
- Audio sample rate
- Number of audio channels for recording.
Summary
Nested classes | |
---|---|
Configuration for an audio encoder. |
|
Configuration for a video encoder. |
Public methods | |
---|---|
MutableList<EncoderProfiles.AudioProfile!> |
Returns the defined audio encoder profiles. |
Int |
Default recording duration in seconds before the session is terminated. |
Int |
Recommended output file format |
MutableList<EncoderProfiles.VideoProfile!> |
Returns the defined video encoder profiles. |
Public methods
getAudioProfiles
fun getAudioProfiles(): MutableList<EncoderProfiles.AudioProfile!>
Returns the defined audio encoder profiles.
The list may be empty. This means there are no audio encoder profiles defined. Otherwise, the first profile is the default audio profile.
Return | |
---|---|
MutableList<EncoderProfiles.AudioProfile!> |
This value cannot be null . |
getDefaultDurationSeconds
fun getDefaultDurationSeconds(): Int
Default recording duration in seconds before the session is terminated. This is useful for applications like MMS that have a limited file size requirement. This could be 0 if there is no default recording duration.
getRecommendedFileFormat
fun getRecommendedFileFormat(): Int
Recommended output file format
Return | |
---|---|
Int |
Value is android.media.MediaRecorder.OutputFormat#DEFAULT , android.media.MediaRecorder.OutputFormat#THREE_GPP , android.media.MediaRecorder.OutputFormat#MPEG_4 , android.media.MediaRecorder.OutputFormat#AMR_NB , android.media.MediaRecorder.OutputFormat#AMR_WB , android.media.MediaRecorder.OutputFormat.AAC_ADIF, android.media.MediaRecorder.OutputFormat#AAC_ADTS , android.media.MediaRecorder.OutputFormat#MPEG_2_TS , android.media.MediaRecorder.OutputFormat#WEBM , android.media.MediaRecorder.OutputFormat.HEIF, or android.media.MediaRecorder.OutputFormat#OGG |
getVideoProfiles
fun getVideoProfiles(): MutableList<EncoderProfiles.VideoProfile!>
Returns the defined video encoder profiles.
The list may be empty. This means there are no video encoder profiles defined. Otherwise, the first profile is the default video profile.
Return | |
---|---|
MutableList<EncoderProfiles.VideoProfile!> |
This value cannot be null . |
