Function Documentation

AVFrame* allocate_frame_video	(	int	pix_fmt,
		int	width,
		int	height
	)

Allocate an FFmpeg's AVFrame structure for video encoding. This is a wrapper function of the FFmpeg's 'av_frame_alloc()' for allocating an AVFrame structure.

Parameters

pix_fmt	FFmpeg's video pixel-format identifier.
width	Video frame width.
height	Video frame height. return Pointer to the allocated AVFrame structure.

Definition at line 185 of file proc_frame_2_ffmpeg.c.

proc_frame_ctx_t* avframe_2_proc_frame_ctx

(

const void *

avframe

)

Transform FFmpeg's AVFrame structure to a processor frame context structure (type proc_frame_ctx_t).

Parameters

avframe

Opaque pointer to the AVFrame structure. return Pointer to the processor frame context structure.

Definition at line 325 of file proc_frame_2_ffmpeg.c.

void avframe_release

(

void **

ref_avfame

)

Release FFmpeg's AVFrame structure. This function is a wrapper of FFmpeg's 'av_frame_free()'.

Parameters

ref_avfame

Opaque reference to a pointer to an AVFrame structure to be released.

Definition at line 228 of file proc_frame_2_ffmpeg.c.

proc_frame_ctx_t* avpacket_2_proc_frame_ctx

(

const void *

avpacket_arg

)

Transform FFmpeg's AVPacket structure to a processor frame context structure (type proc_frame_ctx_t).

Parameters

avpacket_arg

Opaque pointer to the AVPacket structure. return Pointer to the processor frame context structure.

Definition at line 236 of file proc_frame_2_ffmpeg.c.

void avpacket_release

(

void **

ref_avpacket

)

Release FFmpeg's AVPacket structure. This function is a wrapper of FFmpeg's 'av_packet_free()'.

Parameters

ref_avpacket

Opaque reference to a pointer to an AVPacket structure to be released.

Definition at line 316 of file proc_frame_2_ffmpeg.c.

void* proc_frame_ctx_2_avframe

(

const proc_frame_ctx_t *

proc_frame_ctx

)

Transform a processor frame context structure (type proc_frame_ctx_t) to an FFmpeg's AVFrame structure.

Parameters

proc_frame_ctx

Pointer to the processor frame context structure. return Opaque pointer that actually can be casted to an AVFrame structure.

Definition at line 47 of file proc_frame_2_ffmpeg.c.

void* proc_frame_ctx_2_avpacket

(

const proc_frame_ctx_t *

proc_frame_ctx

)

Transform a processor frame context structure (type proc_frame_ctx_t) to an FFmpeg's AVPacket structure.

Parameters

proc_frame_ctx

Pointer to the processor frame context structure. return Opaque pointer that actually can be casted to an AVPacket structure.
