Wim Taymans 1635bc0a45 audioconvert: cleanups and add some docs
Add docs for the internal audioconvert object before moving it to the
audio library.
Remove get_sizes and implement the trivial logic in the element.
Remove some unused orc functions

Wim Taymans c36ac3ce45 audioconvert: move audio quantize code to libs
Move the audio quantize code from audioconvert to the audio library.
work on making an audio converter helper function similar to the video
converter.
Fold fastrandom directly into the quantizer, add some ORC code to
optimize this later.

Wim Taymans a7789854d5 audio-channels: rename get_default_mask
Rename _get_default_mask() to _get_fallback_mask() to make it more
clear that the function only provides a fallback if nothing else can be
done. Also clarify this in the documentation.

API: gst_audio_channel_get_fallback_mask()

Wim Taymans f86ed8cdf6 audio-channels: make method to get default channel-mask
Add a new method to get the default channel-mask.
Use the new method on audiodecoder and audioconvert.

Wim Taymans cd6c29e071 audioconvert: make the quantizer a reusable object
Turn the quantizer into a reusable object.

Sebastian Dröge 010e35afa7 audioconvert: Also copy metas if their API has no tags attached to it
This is the default basetransform behaviour, being more strict than that
is not really useful.

Luis de Bethencourt 69f66aff9e Rename property enums from ARG_ to PROP_
Property enum items should be named PROP_ for consistency and readability.

Tim-Philipp Müller bcb8068e27 docs: remove outdated and pointless 'Last reviewed' lines from docs
They are very confusing for people, and more often than not
also just not very accurate. Seeing 'last reviewed: 2005' in
your docs is not very confidence-inspiring. Let's just remove
those comments.

Matej Knopp 12f85c325d audioconvert: Map buffer as READWRITE if the buffer and memory is writable

Tim-Philipp Müller f317061b9c audioconvert: simplify fixate_format function some more
If we have no output format yet, any format will do. The
!out_info condition existed in every path, so just split
it our for clarity. KISS.

Tim-Philipp Müller 7a481c13ae audioconvert: make fixate function more readable

a little bit mor readable.

Sebastian Dröge 9e6021fe4b audioconvert: Always prefer the input format if possible
Previously we could've chosen another format with the same
depth even if the input format was possible.

Also make sure to chose according to the order in the
caps.

Sebastian Dröge bc4389806d audioconvert: Also ignore the SIGNED flag when matching an output format 2012-11-01 14:31:29 +01:00
Rasmus Rohde c286f8ffa2 audioconvert: Prefer output formats with the same depth or at least a higher depth
Enhance current code to prefer an exact match on sample depth if
possible. Also ignore GST_AUDIO_FORMAT_FLAG_UNPACK when checking
equality on the flags.

Wim Taymans dae848818d audio: rework audio caps.
Rework the audio caps similar to the video caps. Remove
width/depth/endianness/signed fields and replace with a simple string
format and media type audio/x-raw.
Create a GstAudioInfo and some helper methods to parse caps.
Remove duplicate code from the ringbuffer and replace with audio info.
Use AudioInfo in the base audio filter class.
Port elements to new API.

Sebastian Dröge 4fcd621101 audioconvert: Use new gst_caps_is_subset_structure() API
This prevents one copy of every structure and creating a new caps
instance.

Sebastian Dröge d590bce5f7 audioconvert: Optimize transform_caps()
If the second and next caps structures are a subset of the already existing
transformed caps we can safely skip them because we would transform them to
the same caps again.

This makes gst_pad_get_caps() on an audiotestsrc ! audioconvert !
audioconvert ! audioconvert ! fakesink pipeline about 1.7 times faster.

Stefan Kost f514be993c audioconvert: cleanup helper code
make_lossless_changes() returns the same structure that we're passing (probably
to enable chaining). Instead of reusing s and making it point to s2 as well,
keep using s2. Drop the assignment which in the 2nd case is a dead one anyway.
