+]>
+
+There's a simple and a complex syntax to declare the availability of a
+media codec:
+
+A codec that properly follows the OpenMax spec and therefore doesn't have any
+quirks and that only supports a single content type can be declared like so:
+
+ <MediaCodec name="OMX.foo.bar" type="something/interesting" />
+
+If a codec has quirks OR supports multiple content types, the following syntax
+can be used:
+
+ <MediaCodec name="OMX.foo.bar" >
+ <Type name="something/interesting" />
+ <Type name="something/else" />
+ ...
+ <Quirk name="requires-allocate-on-input-ports" />
+ <Quirk name="requires-allocate-on-output-ports" />
+ <Quirk name="output-buffers-are-unreadable" />
+ </MediaCodec>
+
+Only the three quirks included above are recognized at this point:
+
+"requires-allocate-on-input-ports"
+ must be advertised if the component does not properly support specification
+ of input buffers using the OMX_UseBuffer(...) API but instead requires
+ OMX_AllocateBuffer to be used.
+
+"requires-allocate-on-output-ports"
+ must be advertised if the component does not properly support specification
+ of output buffers using the OMX_UseBuffer(...) API but instead requires
+ OMX_AllocateBuffer to be used.
+
+"output-buffers-are-unreadable"
+ must be advertised if the emitted output buffers of a decoder component
+ are not readable, i.e. use a custom format even though abusing one of
+ the official OMX colorspace constants.
+ Clients of such decoders will not be able to access the decoded data,
+ naturally making the component much less useful. The only use for
+ a component with this quirk is to render the output to the screen.
+ Audio decoders MUST NOT advertise this quirk.
+ Video decoders that advertise this quirk must be accompanied by a
+ corresponding color space converter for thumbnail extraction,
+ matching surfaceflinger support that can render the custom format to
+ a texture and possibly other code, so just DON'T USE THIS QUIRK.

+ * thinkpad_ec.c - ThinkPad embedded controller LPC3 functions

+ * The LPC protocol and terminology are documented here:
