Quality level corresponding to the 720p (1280 x 720) resolution.
Constant Value: 5 (0x00000005)

int QUALITY_HIGH_SPEED_1080P

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.

int QUALITY_HIGH_SPEED_720P

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 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.
See also:
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.

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.
