问题
I am trying to overlay a dvdsub file pair (*.idx + *.sub) to a video file.
Here is the sub pair.
This is the batch script with the command line I am trying to use:
@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%
This however only accepts 720x576 VOBsub files. And also the color gets inverted.
My video however is 1080p and do have a 1920x1080 VOBsub file pair, but when I trying use them, I get an error sub2video: rectange (xxx xxx xxx xxx) overflowing 720 576
Looks like adding -canvas_size 1920x1080 before -i %srcSubFile% handles the error on the canvas size. But I can't figure out the color.
The full output:

I would like to input the 1920x1080 VOBsub file pair and overlay it on the 1080p video with 24bit original colors.
Can somebody give me the correct command line for this?
And as it seems that the VOBsub are low res, is there any means that allow overlaying 1920x1080 24 bit pngs using ffmpeg?
