| 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. |
