| 33 | There's a simple and a complex syntax to declare the availability of a |
| 34 | media codec: |
| 35 | |
| 36 | A codec that properly follows the OpenMax spec and therefore doesn't have any |
| 37 | quirks and that only supports a single content type can be declared like so: |
| 38 | |
| 39 | <MediaCodec name="OMX.foo.bar" type="something/interesting" /> |
| 40 | |
| 41 | If a codec has quirks OR supports multiple content types, the following syntax |
| 42 | can be used: |
| 43 | |
| 44 | <MediaCodec name="OMX.foo.bar" > |
| 45 | <Type name="something/interesting" /> |
| 46 | <Type name="something/else" /> |
| 47 | ... |
| 48 | <Quirk name="requires-allocate-on-input-ports" /> |
| 49 | <Quirk name="requires-allocate-on-output-ports" /> |
| 50 | <Quirk name="output-buffers-are-unreadable" /> |
| 51 | </MediaCodec> |
| 52 | |
| 53 | Only the three quirks included above are recognized at this point: |
| 54 | |
| 55 | "requires-allocate-on-input-ports" |
| 56 | must be advertised if the component does not properly support specification |
| 57 | of input buffers using the OMX_UseBuffer(...) API but instead requires |
| 58 | OMX_AllocateBuffer to be used. |
| 59 | |
| 60 | "requires-allocate-on-output-ports" |
| 61 | must be advertised if the component does not properly support specification |
| 62 | of output buffers using the OMX_UseBuffer(...) API but instead requires |
| 63 | OMX_AllocateBuffer to be used. |
| 64 | |
| 65 | "output-buffers-are-unreadable" |
| 66 | must be advertised if the emitted output buffers of a decoder component |
| 67 | are not readable, i.e. use a custom format even though abusing one of |
| 68 | the official OMX colorspace constants. |
| 69 | Clients of such decoders will not be able to access the decoded data, |
| 70 | naturally making the component much less useful. The only use for |
| 71 | a component with this quirk is to render the output to the screen. |
| 72 | Audio decoders MUST NOT advertise this quirk. |
| 73 | Video decoders that advertise this quirk must be accompanied by a |
| 74 | corresponding color space converter for thumbnail extraction, |
| 75 | matching surfaceflinger support that can render the custom format to |
| 76 | a texture and possibly other code, so just DON'T USE THIS QUIRK. |
