[FFmpeg-devel] [PATCH] libavcodec/dvbsub: fix for Display Definition Segment

[Pierre Yves MORDRET]

Given ETSI EN 300 743 V1.3.1 (2006-11), 7.2.1 Display definition segment
display window parameters are given in this order XMin, XMax, YMin, YMax
if  display_window_flag is set, but here this is not the case.
As a consequence the DVB subtitles are not displayed upon some videos.
