vlc.VideoUnlockCb

class vlc.VideoUnlockCb

Bases: ctypes.c_void_p

Callback prototype to unlock a picture buffer.

When the video frame decoding is complete, the unlock callback is invoked. This callback might not be needed at all. It is only an indication that the application can now read the pixel values if it needs to.

Note

A picture buffer is unlocked after the picture is decoded, but before the picture is displayed.

Parameters:

  • opaque – private pointer as passed to libvlc_video_set_callbacks() [IN].

  • picture – private pointer returned from the VideoLockCb. callback [IN].

  • planes – pixel planes as defined by the VideoLockCb. callback (this parameter is only for convenience) [IN].

Initialize self. See help(type(self)) for accurate signature.
