JDK-8199527 added fix for HLS streams (unfortunately I was not able to find repro case and more details on why it was added) in gstappsink.c line 659-678 to store current caps which can be lost during seek/flush. However, this workaround broke code in gst_app_sink_render_common() line 939 which was restoring caps if they were flushed, since we set last_caps to non NULL value. Since code in gst_app_sink_render_common() did not work to propagate caps to sample our rendering code was dropping frames without caps. Fixed by setting caps on sample in HLS workaround code.
