Description Fei 2017-09-28 01:14:20 UTC 
Only the first frame display on my screen for VP8/VP9 streams encoded by libyami.

cmdline: : gst-launch-1.0 filesrc location=720P_tractor_1280x720_5520frames.yuv_cqp_qp120_ip.vp8 ! ivfparse ! vaapivp8dec ! vaapisink

gst-launch-1.0 filesrc location=4K_tractor_3840x2160_1000frames.yuv_cbr_bt12000_ip.vp9 ! ivfparse ! vaapivp9dec ! vaapisink

streams can be found by link:

I found it drops all frames after the first frame because of invalid timestamp.
And it seems to be same on every player: gst-play, ffplay, vlc.

But mpv plays it, but not quite good and outputs tons of warnings about timestamp.

Could you confirm the media you shared?
Comment 2 Fei 2017-09-28 03:59:33 UTC 
@guangxin, could you help to check why yamiencode gives VP8/VP9 encoded streams invalid timestamp?
Comment 3 XuGuangxin 2017-09-28 04:15:19 UTC 
The output is ivf file. yami did not write timestamp to it. 
@Fei, you can file bug for yami
Comment 4 Fei 2017-09-28 05:43:49 UTC 
@guangxin, bug filed: https://github.com/01org/libyami/issues/800

Closing this as invalid. If we can probe is a problem in gstreamer-vaapi please reopen.
