[FFmpeg-devel] [PATCH]ffplay 1/2: fix subtitles vertical resolution

[Björn Axelsson]

First patch from some recent subtitle work.

This trivial patch fixes a bug in the ffplay.c subtitle renderer
(blend_subrect) which basically halves the vertical resolution of
subtitles as each same source pixel is used twice.

The effect of this patch can be easily seen in this sample:
