Summary

Member Variables

Name	Description
int32_t audioBitrate	Audio bitrate. The unit is bit/s.
int32_t audioChannels	Number of channels.
OH_AVRecorder_CodecMimeType audioCodec	Audio encoding format.
int32_t audioSampleRate	Audio sampling rate. The unit is Hz.
OH_AVRecorder_ContainerFormatType fileFormat	Output file format.
int32_t videoBitrate	Video bitrate. The unit is bit/s.
OH_AVRecorder_CodecMimeType videoCodec	Video encoding format.
int32_t videoFrameWidth	Video width. The unit is px.
int32_t videoFrameHeight	Video height. The unit is px.
int32_t videoFrameRate	Video frame rate. The unit is frames per second (FPS).
bool isHdr	Whether HDR videos are recorded. true if recorded, false otherwise. The default value is false.
bool enableTemporalScale	Whether temporal scalable encoding is enabled. When this parameter is set to true, some frames in the encoded output stream can be skipped to optimize encoding efficiency. When it is set to false, all frames in the encoded output stream must be encoded without skipping. For details, see Temporally Scalable Video Coding The default value is false.
