/**
* gst_codec_utils_h265_caps_set_level_tier_and_profile:
* @caps: the #GstCaps to which the level, tier and profile are to be added
* @profile_tier_level: Pointer to the profile_tier_level struct
* @len: Length of the data available in @profile_tier_level.
*
* Sets the level, tier and profile in @caps if it can be determined from
* @profile_tier_level. See gst_codec_utils_h265_get_level(),
* gst_codec_utils_h265_get_tier() and gst_codec_utils_h265_get_profile()
* for more details on the parameters.
*
* Returns: %TRUE if the level, tier, profile could be set, %FALSE otherwise.
*
* Since 1.4
