EncoderConfig & |
EncoderConfig结构体引用类型,GPU编码配置项。 |
EncoderConfig结构体和相关枚举定义如下:
1 2 3 4 5 6 7 | enum EncoderCapability : uint32_t { CAP_NONE, CAP_FORMAT_CONVERT, CAP_VA_ENCODE_H264, CAP_VA_ENCODE_HEVC, CAP_MAX, }; |
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 | enum DeviceNode : uint32_t { DEV_DRI_RENDERD128 = 128, DEV_DRI_RENDERD129 = 129, DEV_DRI_RENDERD130 = 130, DEV_DRI_RENDERD131 = 131, DEV_DRI_OTHER = 132 }; struct FrameSize { uint32_t width = 0; uint32_t height = 0; uint32_t widthAligned = 0; uint32_t heightAligned = 0; bool operator==(const FrameSize &other) { return this->width == other.width && this->height == other.height && this->widthAligned == other.widthAligned && this->heightAligned == other.heightAligned; } bool operator!=(const FrameSize &other) { return this->width != other.width || this->height != other.height || this->widthAligned != other.widthAligned || this->heightAligned != other.heightAligned; } }; |
1 2 3 4 5 6 | struct EncoderConfig { EncoderCapability capability = CAP_NONE; DeviceNode deviceNode = DEV_DRI_OTHER; FrameSize inSize = {}; FrameSize outSize = {}; }; |
返回值说明
数据类型:GpuEncoderErrorCode
取值如下:
- OK:初始化GPU加速实例成功。
- 其他:初始化GPU加速实例失败。
