使用ffmpeg覆盖dvdsub字幕
我正在尝试将dvdsub文件对（* .idx + * .sub）覆盖到视频文件上。
这是我尝试使用命令行的批处理脚本：
@echo off
set srcVidFile1="myvideo.mov"
set srcSubFile=mysub.sub
set srcIdxFile=mysub.idx
set destFile=D:\testsub.mp4
ffmpeg.exe -i %srcVidFile1% -i %srcSubFile% -i %srcIdxFile%
-filter_complex "[0:v][1:s]overlay" -c:s dvdsub -c:v
libx264 -crf 24 -c:a aac -b:a 160K -ar 48K -strict -2 -y
%destFile%
但是，这仅接受720x576 VOBsub文件。而且颜色也会反转。
但是我的视频是1080p，确实有1920x1080 VOBsub文件对，但是当我尝试使用它们时，出现错误 sub2video：矩形（xxx xxx xxx xxx）溢出720576
>就像在-canvas_size 1920x1080之前添加-i %srcSubFile%来处理画布大小错误。但是我不知道颜色。

我想输入1920x1080 VOBsub文件对，并将其覆盖在具有24位原始颜色的1080p视频上。
有人可以给我正确的命令行吗？
而且似乎VOBsub的分辨率较低，是否有任何方法可以使用ffmpeg覆盖1920x1080 24位png？
