I have a recording from an old surveillance camera in the “.h264” format. That’s the file format name. It opens with a special player. The audio track is activated either by a specific button or through a context menu in the player. I need to convert the file into another format that includes both video and audio. However, it needs to be done programmatically through Python. Could you please advise how this can be achieved?

Some converters have worked, but the bitrate is too fast compared to the original. I might have many files to process in the future—I need a method to follow an algorithm and handle the files in bulk.
