Strange file not found error

[brooklyn097]

Hi,
This error caused if i do the conversion in any folder but not /root

• Test 1:
  I run: cd /tmp;
  then run: vobsub2srt eng2
  it will throw error message like this:

VobSub: Can't open IDX file
fopen Vobsub file failed: No such file or directory
VobSub: Can't open SUB file
Couldn't open VobSub files 'eng2.idx/.sub'

And i'm sure that in /tmp folder, the file named eng2.idx and eng2.sub are existing.

• Test 2:
  I cd back to /root by command: cd /root;
  then run vobsub2srt /tmp/eng2
  It will throw them same error above.

• Test 3:
  I move eng2.idx and eng2.sub into /root folder
  then i run vobsub2srt /root/eng2 or cd /root; vobsub2srt eng2; the conversion will be processed without problem.

So i think it's only work if the .idx and .sub file placed in /root folder.
Is this a bug?

I'm having the exact same problem. The following files exist:

video.idx
video.sub

Error message:

$ vobsub2srt --verbose video

    VobSub: Can't open IDX file
    fopen Vobsub file failed: No such file or directory
    VobSub: Can't open SUB file
    Couldn't open VobSub files 'video.idx/.sub'

My C++ is not great, but looking through the code:

• /src/vobsub2srt.c++ calls the function vobsub_open, which exists in /mplayer/vobsub.c
• Based on the first line of output, the code gets to this line, suggesting that the IDX file isn't getting read in properly, but I don't know why.
• Then, based on the second line of output, we get to this line in /mplayer/vobsub.c
• When the mpeg_open function gets called, we get some sort of error, but I'm not sure what.

But, even after tracking all of this down, I have no idea why we get errors when the IDX/SUB files exist anywhere but the /root/ directory. It makes no sense to me.

Same problem here, running on a Raspberry Pi 4.
I didn't try to cp the files to /root to test it.
