vaapih264dec : couldn't find associated picture parameter set with id

[CC]

Hi,

I decode the h264 video by vaapih264dec ,  and I get an error : https://gist.github.com/zombiecong/13f724325a092217428e58335a5a14cf

gstreamer command:

gst-launch-1.0 udpsrc port=10000 ! application/x-rtp,payload=107,encoding-name=H264 ! rtph264depay ! video/x-h264, framerate=30/1 ! h264parse ! vaapih264dec ! vaapipostproc ! video/x-raw, width=160, height=120 ! vaapisink

The parser report this error:

gsth264parser.c:2086:gst_h264_parser_parse_slice_hdr: couldn't find associated picture parameter set with id: 4
gstvaapidecode.c:1119:gst_vaapidecode_parse_frame: parse error -1

So, your video stream isn't providing the PPS when parsing the slice's NALU

Can you provide more info? like a debug with vaapi*:5
and if you could provide the stream would be great.

Thanks for your reply.

The debug log : https://gist.github.com/zombiecong/b7554414c91cea0f49972aae8abd701d

How can I save the stream? Can you provide me  a command to save the stream?

Hi,

I record the RTP stream.

You can use the "rtpplay" tool to replay the RTP stream.

As far as I test, it fails to play with both vaapih264dec and avdec_h264.
I believe the stream is incorrect.
