int32_t Init(EncoderConfig &config) = 0

Parameters

The EncoderConfig structures and related enumeration definitions are as follows:

enum EncoderCapability : uint32_t {
    CAP_NONE,
    CAP_FORMAT_CONVERT, // Enables the format conversion capability.
    CAP_VA_ENCODE_H264, // Enables the H.264 encoding capability.
    CAP_VA_ENCODE_HEVC, // Enables the H.265 encoding capability.
};
enum DeviceNode : uint32_t {
    DEV_DRI_RENDERD128 = 128, // 128 rendering node.
    DEV_DRI_RENDERD129 = 129, // 129 rendering node.
    DEV_DRI_RENDERD130 = 130, // 130 rendering node.
    DEV_DRI_RENDERD131 = 131, // 131 rendering node.
};
struct FrameSize {
    uint32_t width; // Image width.
    uint32_t height; // Image height.
    uint32_t widthAligned; // Image width after alignment.
    uint32_t heightAligned; // Image height after alignment.
}

struct EncoderConfig {
    EncoderCapability capability = CAP_NONE; 
    DeviceNode deviceNode = DEV_DRI_OTHER;
    FrameSize inSize = {};
    FrameSize outSize = {};
};

Returns

Data type: GpuEncoderErrorCode

The value can be:

• OK: The GPU-accelerated instance is successfully initialized.
• Other values except OK: The GPU-accelerated instance fails to be initialized.
