Function Documentation

§ ff_get_bmp_header()

int ff_get_bmp_header	(	AVIOContext *	pb,
		AVStream *	st,
		uint32_t *	size
	)

Read BITMAPINFOHEADER structure and set AVStream codec width, height and bits_per_encoded_sample fields.

Does not read extradata. Writes the size of the BMP file to *size.

Returns: codec tag

§ ff_put_wav_header()

int ff_put_wav_header	(	AVFormatContext *	s,
		AVIOContext *	pb,
		AVCodecParameters *	par,
		int	flags
	)

Write WAVEFORMAT header structure.

Parameters

flags a combination of FF_PUT_WAV_HEADER_* constants

Returns: the size or -1 on error
