[FFmpeg-devel] [PATCH 5/7] avcodec/get_buffer: Don't get AVPixFmtDescriptor unnecessarily

[Andreas Rheinhardt <andreas.rheinhardt@outlook.com>]

It is unused since 3575a495f6dcc395656343380e13c57d48b9f976
(and the error message is dangerous: av_get_pix_fmt_name(format)
returns NULL iff av_pix_fmt_desc_get(format) returns NULL
and using a NULL string for %s would be UB).
