Detailed Description

Function Documentation

avcodec_parameters_alloc()

AVCodecParameters * avcodec_parameters_alloc ( void )

related

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 )

related

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 )

related

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.

av_get_audio_frame_duration2()

int av_get_audio_frame_duration2 ( AVCodecParameters * par, int frame_bytes )

related

This function is the same as av_get_audio_frame_duration(), except it works with AVCodecParameters instead of an AVCodecContext.
