Please, open an issue in the corresponding github repo.
BTW: It’s not a good idea “fixing some bug” on the software you are using, and then telling that it’s not working since your ‘fixes’ may have broken something.
I’m fix it and. Demo is working. But new issue FFMPEG only creates files with a file size of 256Kb.
Example: 256 if file greater than 256kb it not create and i recevied new file 0Kb.
512Kb, 1024Kb.
