pbutils: add codec-specific utility functions for AAC This allows us to add generic codec-specific functionality, like extracting profile/level data from headers, without having to duplicate code across demuxers and typefindfunctions. As a starting point, this moves over AAC level extraction code from typefindfunctions, so it can be reused in qtdemux, etc. https://bugzilla.gnome.org/show_bug.cgi?id=617314 API: gst_codec_utils_aac_get_sample_rate_from_index() API: gst_codec_utils_aac_get_level()

/* GStreamer base utils library codec-specific utility functions
typefinding: add AAC level to ADTS caps This adds code to calculate the level for a given AAC stream and export it in the stream caps. For AAC LC streams, the level is calculated according to the definition under the AAC Profile. For other streams, the definition under the Main Profile is used. HE-AAC support is still to be done, and is dependent on detecting the presence of SBR and PS in the stream. Level is added as a field of type string because that's the way it's done in H.264 caps as well. There are only a few possible levels, so not using a numerical type is not too painful in this case, and consistency is nice. Fixes #613589.

pbutils: GST_EXPORT -> GST_PBUTILS_API We need different export decorators for the different libs. For now no actual change though, just rename before the release, and add prelude headers to define the new decorator to GST_EXPORT.

typefinding: add AAC level to ADTS caps This adds code to calculate the level for a given AAC stream and export it in the stream caps. For AAC LC streams, the level is calculated according to the definition under the AAC Profile. For other streams, the definition under the Main Profile is used. HE-AAC support is still to be done, and is dependent on detecting the presence of SBR and PS in the stream. Level is added as a field of type string because that's the way it's done in H.264 caps as well. There are only a few possible levels, so not using a numerical type is not too painful in this case, and consistency is nice. Fixes #613589.

pbutils: add codec-specific utility functions for AAC This allows us to add generic codec-specific functionality, like extracting profile/level data from headers, without having to duplicate code across demuxers and typefindfunctions. As a starting point, this moves over AAC level extraction code from typefindfunctions, so it can be reused in qtdemux, etc. https://bugzilla.gnome.org/show_bug.cgi?id=617314 API: gst_codec_utils_aac_get_sample_rate_from_index() API: gst_codec_utils_aac_get_level()
