I'm not sure if this is actually supposed to work because we don't have proper synchronization between kernel drivers with DMA-buf jet. <blockquote type="cite">Maybe the idea of the patch is good but something is still wrong.</blockquote> While it is not the proper solution I would say let's keep the pipeline draining during exporting the handle for now if that's really necessary for your use case. Please test the attached patch. Coding the patch I've just noticed that there wasn't a pipe->flush() before exporting the handle. Does it work as well if you just flush the pipeline without waiting for the commands to be finished? Regards, Christian.
