Data Structures | |
struct | vda_context |
This structure is used to provide the necessary configurations and data to the VDA FFmpeg HWAccel implementation. More... | |
struct | AVVDAContext |
This struct holds all the information that needs to be passed between the caller and libavcodec for initializing VDA decoding. More... | |
Functions | |
int | ff_vda_create_decoder (struct vda_context *vda_ctx, uint8_t *extradata, int extradata_size) |
Create the video decoder. More... | |
int | ff_vda_destroy_decoder (struct vda_context *vda_ctx) |
Destroy the video decoder. More... | |
AVVDAContext * | av_vda_alloc_context (void) |
Allocate and initialize a VDA context. More... | |
int | av_vda_default_init (AVCodecContext *avctx) |
This is a convenience function that creates and sets up the VDA context using an internal implementation. More... | |
int | av_vda_default_init2 (AVCodecContext *avctx, AVVDAContext *vdactx) |
This is a convenience function that creates and sets up the VDA context using an internal implementation. More... | |
void | av_vda_default_free (AVCodecContext *avctx) |
This function must be called to free the VDA context initialized with av_vda_default_init(). More... | |

int ff_vda_destroy_decoder | ( | struct vda_context * | vda_ctx | ) |
AVVDAContext* av_vda_alloc_context | ( | void | ) |
Allocate and initialize a VDA context.
This function should be called from the get_format() callback when the caller selects the AV_PIX_FMT_VDA format. The caller must then create the decoder object (using the output callback provided by libavcodec) that will be used for VDA-accelerated decoding.
When decoding with VDA is finished, the caller must destroy the decoder object and free the VDA context using av_free().
int av_vda_default_init | ( | AVCodecContext * | avctx | ) |
This is a convenience function that creates and sets up the VDA context using an internal implementation.
avctx | the corresponding codec context |
