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. |
