OSError : [Errno 9] Bad file descriptor when downloading using pytube and playing with discord.py
15 septembre 2022, par Trevor MathisenWhen using pytube to download a YouTube video and discord.py to play it, I am getting a OSError : [Errno 9] Bad file descriptor error. I've had this working at one point and can't seem to figure out what I changed which broke it.

I've mounted the /media/ dir during docker -v and can see the file is getting downloaded and when I copy the file to my local machine I can play it in an audio player.


The program can access the SQLite database right next to the files in question just fine.


I've deployed the container locally and to two different VPS's with the same file structure with the same behavior. I'm ripping my hair out.

ffmpeg framemd5 errors with FFV1.mkv in Windows
19 août 2022, par jim_e_jibI'm using framemd5 to check lossless transcoding to FFV1.mkv and am getting mismatches between my source and FFV1 files.


If I generate the framemd5 files in Windows, I get presentation timestamp mismatches on the audio between the source file and FFV1. The MD5s themselves match.


If I generate the framemd5 files for the FFV1 in Linux (WSL), everything matches just fine.


Is there something I am doing wrong, or is this just a quirk of the ffmpeg/FFV1/Windows combination ?


I am using ffmpeg version 2022-07-14-git-882aac99d2-full_build-www.gyan.dev in Windows and
ffmpeg version 4.4.2-0ubuntu1 20.04.sav2 in WSL.


Many thanks !

Cryptic `ffmpeg` + Python error : `Cannot find a matching stream for unlabeled input pad 0 on filter Parsed_crop_1`

Cannot find a matching stream for unlabeled input pad 0 on filter Parsed_crop_1


What is the problem here ? Also, how does one interpret this cryptic error message at the end of the log output :


Cannot find a matching stream for unlabeled input pad 0 on filter Parsed_crop_1

E.g. what is
input pad 0, why is itunlabeled, and why can't it find a matching stream ?

(PS. : Yes, I do have a habit of excessively documenting my code. ^^)
