[FFmpeg-devel] [PATCH] avcodec/decode: log hwaccel name

[Zhao Zhili]

From: Zhao Zhili <zhilizhao at tencent.com>

Many users mistakenly think that hwaccel is an instance of a decoder,
and cannot find the corresponding decoder name in the logs. Log
hwaccel name so user know hwaccel has taken effect.
