Parameters:

	codec_id	the codec to match
	pix_fmt	the pixel format to match

Returns:

the hardware accelerated codec, or NULL if none was found.

void ff_log_ask_for_sample	(	void *	avc,
		const char *	msg
	)

Logs a generic warning message asking for a sample.

Parameters:

[in]	avc	a pointer to an arbitrary struct of which the first field is a pointer to an AVClass struct
[in]	msg	string containing an optional message, or NULL if no message

void ff_log_missing_feature	(	void *	avc,
		const char *	feature,
		int	want_sample
	)

Logs a generic warning message about a missing feature.

Parameters:

[in]	avc	a pointer to an arbitrary struct of which the first field is a pointer to an AVClass struct
[in]	feature	string containing the name of the missing feature
[in]	want_sample	indicates if samples are wanted which exhibit this feature. If want_sample is non-zero, additional verbage will be added to the log message which tells the user how to report samples to the development mailing list.
