# qtibatch Source: [https://docs.qualcomm.com/doc/80-70020-50/topic/qtibatch.html](https://docs.qualcomm.com/doc/80-70020-50/topic/qtibatch.html) The qtibatch plugin uses frame aggregation techniques to group several audio/video frames into one buffer for preprocessing. Batching can be done on a single stream (in which case the batch size is 1) or in many parallel streams. - The loaded model in the ML inferencing plugin downstream determines the batch size. - [GstCaps](https://gstreamer.freedesktop.org/documentation/gstreamer/gstcaps.html) shared the batch size with upstream. - When creating the pipeline, the input sources must be lower or equal to the batch size. Inputs above the batch size are ignored. - The plugin places the buffers from each source as separate [GstMemory](https://gstreamer.freedesktop.org/documentation/gstreamer/gstmemory.html#GstMemory) blocks along with their corresponding batch index. For example, source 0 at batch index 0 and source 1 at batch index 1.
