hi,
?0?2 ?0?2I am sorry to trouble you??
?0?2 ?0?2We encountered the problem of video picture jam in the process of
using the spice protocol, and the audio and video out of sync problem
also appeared in the drag and drop player window. When trying to solve
the problem, we changed the encoding method from mjpeg to h264, but
the problem didn't seem to improve. After that we tried to encode with
hardware, but it failed. It seems that kvm can't access NVIDIA's
device driver.
?0?2 ?0?2Two question as follows??
?0?2 ?0?21??I want to confirm whether kvm can access the hardware driver and
perform hardware coding??
?0?2 ?0?22??Have you ever encountered video jams, audio and video out of
sync? How to solve it? Wouldn't it be better to decode on the client
side via hardware?
As Victor mentioned video encoding is using x264enc. if i'm not mistaken
it's predefined to ultrafast encoding
which may cause video jams (since it is sw encoding high quality
encoding will probably be too slow and high cpu
consumer).
IIRC audio and video should be synchronized in both cases.
Client side should use hw decoding in case hw gstreamer decoder plugin
is available (although some additional
sw graphical operations may be done by spice after the decoding phase)
Snir.

Hope that I will receive your reply soon??ths??
