104 <h3>Adding OpenMAX AL to your application source code</h3>
106 OpenMAX AL is a C API, but is callable from both C and C++ code.
108 Add the following lines to your code:
134 For robustness, we recommend that you examine the <code>XAresult</code>
135 value which is returned by most APIs. Use of <code>assert</code>
139 for more information. In the supplied example, we have used <code>assert</code>

226 The source data locator must be <code>XA_DATALOCATOR_ANDROIDBUFFERQUEUE</code>
229 The source data format must be <code>XADataFormat_MIME</code>.
230 Initialize <code>mimeType</code> to <code>XA_ANDROID_MIME_MP2TS</code>,

311 Set the <code>hWindow</code> field to an
312 <code>ANativeWindow *</code> and set <code>hDisplay</code> to <code>NULL</code>.
313 You can get a <code>ANativeWindow *</code> handle from an <code>android.view.Surface</code>,
320 Don't forget to free this handle in your shutdown code with <code>ANativeWindow_release</code>.
331 <code>xaCreateEngine</code> recognizes, but ignores, these engine options:

382 operation; be prepared to deal with a different result code.

423 <li><code>XAchar</code> will change from <code>unsigned char</code>
424 to <code>char</code>. This primarily affects the MIME data format.
425 <li><code>XADataFormat_MIME.mimeType</code> will be renamed to <code>pMimeType</code>.
426 We recommend that you initialize the <code>XADataFormat_MIME</code>
428 rather than by field name, to isolate your code
429 In the example code we have used this technique.

501 There is no associated value, so <code>itemSize</code> must be zero.
507 expressed in <code>itemData</code> as a 64-bit unsigned integer in units of 90 kHz clock ticks.
508 The <code>itemSize</code> should be either zero or 8.
517 for these use <code>XA_ANDROID_ITEMKEY_FORMAT_CHANGE</code>.
