Description of your issue, suggested solution and other information

After a livestream is streamed on youtube, upon ending, the stream is sometimes automatically uploaded as a video to youtube. My bug is that when downloading this video of the stream, right after the stream is uploaded, there seems to be a consistent bug, that i am having for months now, that the youtube-dl completely corrupts the downloaded file despite seeming to download the file correctly, but the resulting file is always some 50-60kb file (impossible for a 1 hour stream to be so low) and is always a few seconds of the "Hangouts On Air" picture. i have attached 1 file that is the output of the program.

thanks for helping, really love the project!
