Sorry, I must use e-mail client because our e-mail server is Exchange not SMTP.
The patch system seems cannot process UTF-8 Chinese characters correctly.
I try sending it as attachment again.

* [FFmpeg-devel] [PATCH v2] avcodec/mips: Fix MMI macro replaces in HEVC Decoder

The latest commit of Loongson MMI macro replaces were incorrect.
It makes a mass of green tints on HEVC videos when playing. I've
compared it with the older MMI implementation, and found out that
several lines have been replaced by wrong macros.
