Since we use fixed values for some fields like width and height they can be wrong, and would get picked by some formats filters.
For example for https://www.youtube.com/watch?v=EQCrhbBxsjA the biggest height is 720 and for nondash formats it's set to 1440, so -f 'bestvideo[height>=1200]+bestaudio' would incorrectly pick the nondash format, instead it should report that the requested format is not available.
After installing youtube-dl with this method
sudo wget https://yt-dl.org/downloads/latest/youtube-dl -O /usr/local/bin/youtube-dl
sudo chmod a+xr /usr/local/bin/youtube-dl
When i try to use it, i get this error
python: can't open file '/usr/local/bin/youtube-dl': [Errno 13] Permission denied
The correct chmod is a+xr
