Re: 答复: how to open jpg binary file (/tmp/spice_dump/x.jpg)?

Yes. It is some spice code which is calling dump_jpeg.

After apply this patch, jpeg file can be open by eog.

The call is correct. What is wrong is dump_jpeg which should handle all chunks and not assume that pointer
is raw data.
Thanks for the report.
What are you trying to do dumping jpeg images?

I don't understand how this relates to spice? Is this some spice code
which is calling dump_jpeg?
