Steps:Fix VLSUB 0.9.13 Freeze/Crash
Download the Notepad++ and install it on your computer.
Now open Notepad++ and go to Plugins > Plugin Manager -> Show Plugin Manager.
Find “Hex Editor” in the list and install it. Notepad++ will reinstall.
1) Go to the installed location of VLC (most probably Program Files); From there navigate to: VideoLAN > VLC > lua > extensions
2) Now open “VLSub.luac” in notepad++ and from Plugins select Hex Editor -> View in Hex.
3) Now open Find box or press CTRL + F and search for “HTTP/1.1”.
There when found replace HTTP/1.1 with HTTP/1.0
4) Now save the file by pressing CTRL + S. If Notepad++ asks you to run as admin. Select yes and it will automatically run as admin. Now save again.
Once done open any movie file in VLC and try searching for Subtitles using VLSUB 0.9.13 or any other version. Hopefully it will work.
