avcodec_parameters_alloc()

AVCodecParameters* avcodec_parameters_alloc

(

void

)

Allocate a new AVCodecParameters and set its fields to default values (unknown/invalid/0).

The returned struct must be freed with avcodec_parameters_free().

avcodec_parameters_free()

void avcodec_parameters_free

(

AVCodecParameters **

par

)

Free an AVCodecParameters instance and everything associated with it and write NULL to the supplied pointer.

avcodec_parameters_copy()

int avcodec_parameters_copy	(	AVCodecParameters *	dst,
		const AVCodecParameters *	src
	)

Copy the contents of src to dst.

Any allocated fields in dst are freed and replaced with newly allocated duplicates of the corresponding fields in src.

Returns

>= 0 on success, a negative AVERROR code on failure.
