|
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.
