int QUALITY_1080P
Quality level corresponding to the 1080p (1920 x 1080) resolution. Note that the vertical resolution for 1080p can also be 1088, instead of 1080 (used by some vendors to avoid cropping during video playback).
Constant Value: 6 (0x00000006)

Constant Value: 8 (0x00000008)
int QUALITY_480P
Quality level corresponding to the 480p (720 x 480) resolution. Note that the horizontal resolution for 480p can also be other values, such as 640 or 704, instead of 720.
Constant Value: 4 (0x00000004)
int QUALITY_720P
Quality level corresponding to the 720p (1280 x 720) resolution.
Constant Value: 5 (0x00000005)
int QUALITY_CIF
Quality level corresponding to the cif (352 x 288) resolution.
Constant Value: 3 (0x00000003)
int QUALITY_HIGH
Quality level corresponding to the highest available resolution.
Constant Value: 1 (0x00000001)
int QUALITY_HIGH_SPEED_1080P
High speed ( >= 100fps) quality level corresponding to the 1080p (1920 x 1080 or 1920x1088) resolution.
Constant Value: 2004 (0x000007d4)
int QUALITY_HIGH_SPEED_2160P
High speed ( >= 100fps) quality level corresponding to the 2160p (3840 x 2160) resolution.
Constant Value: 2005 (0x000007d5)
int QUALITY_HIGH_SPEED_480P
High speed ( >= 100fps) quality level corresponding to the 480p (720 x 480) resolution. Note that the horizontal resolution for 480p can also be other values, such as 640 or 704, instead of 720.
Constant Value: 2002 (0x000007d2)
int QUALITY_HIGH_SPEED_720P
High speed ( >= 100fps) quality level corresponding to the 720p (1280 x 720) resolution.
Constant Value: 2003 (0x000007d3)
int QUALITY_HIGH_SPEED_HIGH
High speed ( >= 100fps) quality level corresponding to the highest available resolution.
Constant Value: 2001 (0x000007d1)
int QUALITY_HIGH_SPEED_LOW
High speed ( >= 100fps) quality level corresponding to the lowest available resolution.
For all the high speed profiles defined below ((from QUALITY_HIGH_SPEED_LOW
to
QUALITY_HIGH_SPEED_2160P
), they are similar as normal recording profiles, with just
higher output frame rate and bit rate. Therefore, setting these profiles with
setProfile(CamcorderProfile)
without specifying any other encoding parameters will
produce high speed videos rather than slow motion videos that have different capture and
output (playback) frame rates. To record slow motion videos, the application must set video
output (playback) frame rate and bit rate appropriately via
setVideoFrameRate(int)
and setVideoEncodingBitRate(int)
based on the slow motion factor. If the application intends to do the video recording with
MediaCodec
encoder, it must set each individual field of MediaFormat
similarly according to this CamcorderProfile.

int QUALITY_LOW
Quality level corresponding to the lowest available resolution.
Constant Value: 0 (0x00000000)
int QUALITY_QCIF
Quality level corresponding to the qcif (176 x 144) resolution.
Constant Value: 2 (0x00000002)

int audioBitRate
The target audio output bit rate in bits per second
int audioChannels
The number of audio channels used for the audio track
int audioCodec
The audio encoder being used for the audio track.
See also:
int audioSampleRate
The audio sampling rate used for the audio track
int duration
Default recording duration in seconds before the session is terminated. This is useful for applications like MMS has limited file size requirement.
int fileFormat
The file output format of the camcorder profile
See also:
int videoBitRate
The target video output bit rate in bits per second
This is the target recorded video output bit rate if the application configures the video
recording via setProfile(CamcorderProfile)
without specifying any other
MediaRecorder
encoding parameters. For example, for high speed quality profiles (from
QUALITY_HIGH_SPEED_LOW
to QUALITY_HIGH_SPEED_2160P
), this is the bit rate
where the video is recorded with. If the application intends to record slow motion videos
with the high speed quality profiles, it must set a different video bit rate that is
corresponding to the desired recording output bit rate (i.e., the encoded video bit rate
during normal playback) via setVideoEncodingBitRate(int)
. For example, if
QUALITY_HIGH_SPEED_720P
advertises 240fps videoFrameRate
and 64Mbps
videoBitRate
in the high speed CamcorderProfile, and the application intends to
record 1/8 factor slow motion recording videos, the application must set 30fps via
setVideoFrameRate(int)
and 8Mbps ( videoBitRate
* slow motion
factor) via setVideoEncodingBitRate(int)
. Failing to do so will result in
videos with unexpected frame rate and bit rate, or MediaRecorder
error if the output
bit rate exceeds the encoder limit. If the application intends to do the video recording with
MediaCodec
encoder, it must set each individual field of MediaFormat
similarly according to this CamcorderProfile.
int videoCodec
The video encoder being used for the video track
See also:
int videoFrameRate
The target video frame rate in frames per second.
This is the target recorded video output frame rate per second if the application configures
the video recording via setProfile(CamcorderProfile)
without specifying any other
MediaRecorder
encoding parameters. For example, for high speed quality profiles (from
QUALITY_HIGH_SPEED_LOW
to QUALITY_HIGH_SPEED_2160P
), this is the frame rate
where the video is recorded and played back with. If the application intends to create slow
motion use case with the high speed quality profiles, it must set a different video frame
rate that is corresponding to the desired output (playback) frame rate via
setVideoFrameRate(int)
. For example, if QUALITY_HIGH_SPEED_720P
advertises 240fps videoFrameRate
in the CamcorderProfile, and the application
intends to create 1/8 factor slow motion recording videos, the application must set 30fps via
setVideoFrameRate(int)
. Failing to do so will result in high speed videos
with normal speed playback frame rate (240fps for above example). If the application intends
to do the video recording with MediaCodec
encoder, it must set each individual field
of MediaFormat
similarly according to this CamcorderProfile.
CamcorderProfile get (int quality)
Returns the camcorder profile for the first back-facing camera on the device at the given quality level. If the device has no back-facing camera, this returns null.
Parameters | |

int :

Returns | |

CamcorderProfile |
See also:
CamcorderProfile get (int cameraId, int quality)
Returns the camcorder profile for the given camera at the given
quality level.
Quality levels QUALITY_LOW, QUALITY_HIGH are guaranteed to be supported, while
other levels may or may not be supported. The supported levels can be checked using
hasProfile(int, int)
.
QUALITY_LOW refers to the lowest quality available, while QUALITY_HIGH refers to
the highest quality available.
QUALITY_LOW/QUALITY_HIGH have to match one of qcif, cif, 480p, 720p, 1080p or 2160p.
E.g. if the device supports 480p, 720p, 1080p and 2160p, then low is 480p and high is
2160p.
The same is true for time lapse quality levels, i.e. QUALITY_TIME_LAPSE_LOW,
QUALITY_TIME_LAPSE_HIGH are guaranteed to be supported and have to match one of
qcif, cif, 480p, 720p, 1080p, or 2160p.
For high speed quality levels, they may or may not be supported. If a subset of the levels
are supported, QUALITY_HIGH_SPEED_LOW and QUALITY_HIGH_SPEED_HIGH are guaranteed to be
supported and have to match one of 480p, 720p, or 1080p.
A camcorder recording session with higher quality level usually has higher output
bit rate, better video and/or audio recording quality, larger video frame
resolution and higher audio sampling rate, etc, than those with lower quality
level.

boolean hasProfile (int cameraId, int quality)
Returns true if camcorder profile exists for the given camera at the given quality level.
When using the Camera 2 API in LEGACY mode (i.e. when
INFO_SUPPORTED_HARDWARE_LEVEL
is set
to
INFO_SUPPORTED_HARDWARE_LEVEL_LEGACY
),
hasProfile(int)
may return true
for unsupported resolutions. To ensure a
a given resolution is supported in LEGACY mode, the configuration given in
SCALER_STREAM_CONFIGURATION_MAP
must contain the the resolution in the supported output sizes. The recommended way to check
this is with
getOutputSizes(Class)
with the
class of the desired recording endpoint, and check that the desired resolution is contained
in the list returned.
