ff_make_codec_str()

int ff_make_codec_str	(	void *	logctx,
		const AVCodecParameters *	par,
		const AVRational *	frame_rate,
		struct AVBPrint *	out
	)

Make a RFC 4281/6381 like string describing a codec.

Parameters

logctx	a context for potential log messages; if NULL, nothing is logged
par	pointer to an AVCodecParameters struct describing the codec
frame_rate	an optional pointer to AVRational for the frame rate, for deciding the right profile for video codecs
out	the AVBPrint to write the output to

Returns

<0 on error
