[xuguangxin]

could you provide the bitstream to us. It's hard to debug without it.

[xuguangxin]

Hi @waiter89
Is it ok to add some dump function before you sent to yami. We can catch and replay the error bitstream. It will help us debug the code. It is hard to debug the issue if we only have stack.

Hi @waiter89
Any update on this?

[xuguangxin]

Hi @waiter89
I will close this temporaryly, please reopen it if you dumped the clip for this.thanks
