|
|
* to the allocated size. The application does not need to align the allocated
|
|
* data. The callback is triggered when the decoder needs a frame buffer to
|
|
* decode a compressed image into. This function may be called more than once
|
|
* for every call to vpx_codec_decode. The application may set fb->priv to
|
|
* some data which will be passed back in the ximage and the release function
|
|
* call. |fb| is guaranteed to not be NULL. On success the callback must
