593 * @brief Add a release handler to a TDM buffer
595 * TDM has its own buffer release mechanism to let an frontend user know when a TDM buffer
596 * becomes available for a next job. A TDM buffer can be used for TDM to show
597 * it on screen or to capture an output and a layer. After all operations,
598 * TDM will release it immediately when TDM doesn't need it any more.
