Function Documentation

void ffmpeg_video_dec_ctx_deinit	(	ffmpeg_video_dec_ctx_t *	ffmpeg_video_dec_ctx,
		log_ctx_t *	log_ctx
	)

De-initialize FFmpeg's video decoding common context structure previously allocated by a call to 'ffmpeg_video_dec_ctx_init()'. This function release any heap-allocated field or structure member.

Parameters

ffmpeg_video_dec_ctx	Pointer to the video decoding common context structure to be de-initialized.
log_ctx	Externally defined LOG module context structure.

Definition at line 403 of file ffmpeg_video.c.

int ffmpeg_video_dec_ctx_init	(	ffmpeg_video_dec_ctx_t *	ffmpeg_video_dec_ctx,
		int	avcodecid,
		const video_settings_dec_ctx_t *	video_settings_dec_ctx,
		log_ctx_t *	log_ctx
	)

Initialize FFmpeg's video decoding common context structure.

Parameters

ffmpeg_video_dec_ctx	Pointer to the video decoding common context structure to be initialized.
avcodecid	Unambiguous decoder identifier (namely, the decoder type Id.).
video_settings_dec_ctx	Pointer to the initial generic video decoder settings context structure.
log_ctx	Externally defined LOG module context structure.

Returns: Status code (STAT_SUCCESS code in case of success, for other code values please refer to .stat_codes.h).

Definition at line 348 of file ffmpeg_video.c.

int ffmpeg_video_dec_frame	(	ffmpeg_video_dec_ctx_t *	ffmpeg_video_dec_ctx,
		AVPacket *	avpacket_iput,
		fifo_ctx_t *	oput_fifo_ctx,
		log_ctx_t *	log_ctx
	)

Decode a complete video frame. If an output frame is produced, is written to the output FIFO buffer.

Parameters

ffmpeg_video_dec_ctx	Pointer to the video decoding common context structure.
avpacket_iput	Pointer to the (FFmpeg's) input packet structure.
oput_fifo_ctx	Pointer to the output FIFO buffer context structure.
log_ctx	Externally defined LOG module context structure.

Returns: Status code (STAT_SUCCESS code in case of success, for other code values please refer to .stat_codes.h).

void ffmpeg_video_enc_ctx_deinit	(	ffmpeg_video_enc_ctx_t *	ffmpeg_video_enc_ctx,
		log_ctx_t *	log_ctx
	)

De-initialize FFmpeg's video encoding common context structure previously allocated by a call to 'ffmpeg_video_enc_ctx_init()'. This function release any heap-allocated field or structure member.

Parameters

ffmpeg_video_enc_ctx	Pointer to the video encoding common context structure to be de-initialized.
log_ctx	Externally defined LOG module context structure.

Definition at line 163 of file ffmpeg_video.c.

int ffmpeg_video_enc_ctx_init	(	ffmpeg_video_enc_ctx_t *	ffmpeg_video_enc_ctx,
		int	avcodecid,
		const video_settings_enc_ctx_t *	video_settings_enc_ctx,
		log_ctx_t *	log_ctx
	)

Initialize FFmpeg's video encoding common context structure.

Parameters

ffmpeg_video_enc_ctx	Pointer to the video encoding common context structure to be initialized.
avcodecid	Unambiguous encoder identifier (namely, the encoder type Id.).
video_settings_enc_ctx	Pointer to the initial generic video encoder settings context structure.
log_ctx	Externally defined LOG module context structure.

Returns: Status code (STAT_SUCCESS code in case of success, for other code values please refer to .stat_codes.h).

Definition at line 53 of file ffmpeg_video.c.

int ffmpeg_video_enc_frame	(	ffmpeg_video_enc_ctx_t *	ffmpeg_video_enc_ctx,
		AVFrame *	avframe_iput,
		fifo_ctx_t *	oput_fifo_ctx,
		log_ctx_t *	log_ctx
	)

Encode a complete video frame. If an output frame is produced, is written to the output FIFO buffer.

Parameters

ffmpeg_video_enc_ctx	Pointer to the video encoding common context structure.
avframe_iput	Pointer to the (FFmpeg's) input frame structure.
oput_fifo_ctx	Pointer to the output FIFO buffer context structure.
log_ctx	Externally defined LOG module context structure.

Returns: Status code (STAT_SUCCESS code in case of success, for other code values please refer to .stat_codes.h).

void ffmpeg_video_reset_on_new_settings	(	proc_ctx_t *	proc_ctx,
		volatile void *	video_settings_opaque,
		int	flag_is_encoder,
		log_ctx_t *	log_ctx
	)

FFmpeg video CODECS are not generally designed to accept changing settings on run-time. Thus, we have to reset (that is, de-initialize and re-initialize) the CODEC to set new settings while running the processor.

Parameters

proc_ctx	Pointer to the processor (PROC) context structure
video_settings_opaque	Opaque pointer to be casted either to an encoder or decoder video settings context structure.
flag_is_encoder	Set to non-zero to signal that we are resetting an encoder, set to zero to identify a decoder.
log_ctx	Pointer to the LOG module context structure.
