gst10_decoding:

ERROR: from element /GstPipeline:pipeline0/GstH264Parse:h264parse0: GStreamer encountered a general stream error.
Additional debug info:

Is this for gst-vaapi 0.4 or gst-vaapi 1.0?

this is for gst-vaapi 0.4, and it's still not fixed. This issue is not so important.

According to last paragraph of Comment 1, I would think this bug is for gst-vaapi master

It is also for gst-vaapi-master, the dumped .yuv file size is much smaller than the yuv file produced by sw, and then lost frame occured in decoding this file:
gst-launch-1.0 filesrc location=Base_Ext_Main_profile/MR7_BT_B.h264 ! h264parse ! vaapidecode ! vaapisink sync=false

log:
ERROR: from element /GstPipeline:pipeline0/GstH264Parse:h264parse0: GStreamer encountered a general stream error.
Additional debug info:
gstbaseparse.c(3038): gst_base_parse_loop (): /GstPipeline:pipeline0/GstH264Parse:h264parse0:

"This issue is not so important." !! What about network sources ? This behavior an happen a lot of times!

I am also hitting same issue with below pipeline : 


GST_DEBUG=3 gst-launch-1.0 flvmux name=mux streamable=true ! rtmpsink sync=true location="rtmp://xxxxxxx" rtspsrc location="rtsp://admin:admin@192.168.0.162:554/cam/realmonitor?channel=1&subtype=0"   ! rtph264depay ! queue ! h264parse ! vaapidecode ! queue ! vaapiencode_h264 rate-control=cbr tune=high-compression ! mux.



How can it be "not so important" ? I am seeing this issue every few mins when decoding video from my ip camera.

This is a gst-vaapi related bug, please try the latest gst-vaapi. If you still experience this issue, please file a new bug against https://bugzilla.gnome.org/enter_bug.cgi?product=gstreamer-vaapi
