[FFmpeg-devel] [PATCH 1/4] avcodec/libaribb24, ttmlenc, avutil/tx: Remove redundant init of AVBPrint

[Andreas Rheinhardt]

Andreas Rheinhardt:
> An AVBPrint is initialized via av_bprint_init() (or
> av_bprint_init_for_buffer()) which expects uninitialized
> AVBPrints; it is therefore not necessary to zero them before
> the actual initialization.

Will apply this patchset tomorrow unless there are objections.
