cencparser is a custom parser that converts H264/H265 CENC video from AVC to byte-stream format. it is required to be inerted before decryptor on platforms that don't provide secure parsers and decoder only accepts video in byte-stream format.
…e is set This can happend if upstream element (a capsfilter) queires caps during negotiation.

On some platforms, we need to insert a custom parser element (cencparser) to convert H264/H265 video samples from AVC/AVC3 to byte-stream format. This is for platforms that don't provide secure parsers, but decoders only accept video in byte-stream format. So, the cencparser must be inserted before the decryptor to convert samples before they are moved to secure memory.
