--- Comment #10 from Matteo Valdina <matteo.valdina at gmail.com> ---
Thanks for the note about GstForceKeyUnit, I'll give a look.

What I saw that the decode image freeze and the report these logs line

couldn't find associated picture parameter set with id: 5
parse error -1

Adding some logs to the gsth264parse and gstvaapidecoder I found that it
continues to decode the same NALU until the stream ended

codecparsers_h264 gsth264parser.c:2073:gst_h264_parser_parse_slice_hdr: Parsing
NALU 0x7f60c009f6f5 8576
This error condition continue beside that the stream contains new SPS/PPS and
new IDR refering these SPS/PPS.

Thanks
