The `SefSlowMotionVideoSampleTransformer` drops frames by setting `buffer.data = null` and updates the timestamps of the frames it keeps. However, these buffers with dropped frames are still used in the pipeline as they may contain other useful information, specifically whether the end of the input has been reached. So, the timestamps should also be updated for the buffers where frames are dropped. PiperOrigin-RevId: 410797678
