You have error bits in your stream. This may hang the hardware. Do you have mechanism in upper layer to make sure no packet lost?

[xuguangxin]

The this specific problem you can refer to https://github.com/01org/libyami/blob/apache/decoder/vaapidecoder_h265.cpp#L1034 to fix it

[waiter89]

it's unavoidable to lost packet. this crash is h264 stream, no h265 stream

@waiter89 , could you help to attach the video?
