Hi @Hyunjun,
I did what you asked and it is not crashing on the 1.12.2, but I'm a little
confused.

>From my understanding, the udpsrc buffer-size is the size for the socket. I
assume that it is translated to "setsockop(SO_RCV_BUFSIZE. buffer-size value)"
or something similar.

Is this value used also for another purpose?
This value should only affect the buffer size if is too small will lead to a
packet loss.
vaapih264dec is crashing due to an incomplete slice, like when there is a
packet loss?

I plan to use this decoder for receiving a stream from a network so a packet
loss could happen for multiple reasons.
