Class VideoLockCb

object --+        
 ??._CData --+    
 ??.PyCFuncPtr --+

Callback prototype to allocate and lock a picture buffer. Whenever a new video frame needs to be decoded, the lock callback is invoked. Depending on the video chroma, one or three pixel planes of adequate dimensions must be returned via the second parameter. Those planes must be aligned on 32-bytes boundaries.
