To disable Webm video download in yt-dlp via script

[Member RJP]

Of course this can be done by hand, but …

A script fixs video´s name also.

The script:

#!/bin/bash
yad --center --width=500 --height=50 --text-align=center --text="This script install config file for YouTube videos for avoinding webm videos"
if [ $? = 0 ];
then
x-terminal-emulator -e mv $HOME/.config/yt-dlp/config $HOME/.config/yt-dlp/config.orig && \
x-terminal-emulator -e mkdir -p $HOME/.config/yt-dlp && \
x-terminal-emulator -e touch $HOME/.config/yt-dlp/config && 
{                                   
echo '--ignore-errors '
echo '# --no-playlist '
echo '# Save in $HOME '
echo '-o ~/%(title)s.%(ext)s '
echo '# Prefer 1080p or lower resolutions '
echo '-f bestvideo[ext=mp4][width<1280][height<=720]+bestaudio[ext=m4a]/bestvideo[width<1280][height<=720]+bestaudio/best[width<1280][height<=720]/best '
} > $HOME/.config/yt-dlp/config
yad --center --width=900 --height=30 --text-align=center --text="This script installed config file to $HOME/.config/yt-dlp/config file. \
Downloaded videos are coming into your home directory \
You can find backup from $HOME/.config/yt-dlp/config.orig ... if there was file before"
else exit 0
fi

PS. Display flickering when running this script.

Hi RJP,

This script just insures that only mp4 video format videos will download, correct?

It doesn’t force transcoding for other formats (say webm) to mp4 automagically, does it?

Yes, it downloads videos as mp4.

Hi RJP,

My goal was to download a YouTube video as an .mp4 format that would embed and run directly and nicely in an Impress presentation.

When I ran your script, I got an error about the center option.

Then I saw a post in an Unix and Linux Stack Exchange on downloading a specific format and it said to use
youtube-dl -f mp4 <url>

I ran yt-dlp -f mp4 <URL> and the resulting download was an mp4 file.

The only problem is that I still get flickering when it runs directly from the slide show. I am guessing that this is due to a framerate shift that I need to address – perhaps with ffmpeg. But that might be incorrect, because there is no flicker when it runs from mpv.

The script only tells where download comes and which form (mp4). It works ok for me.

If you use youtube-dl, you need to copy $HOME/.config/yt-dlp to $HOME/.config/youtube-dl

cp -ax $HOME/.config/yt-dlp $HOME/.config/youtube-dl

usually with youtube,

yt-dlp -f 22 <URL>

will download a complete mp4 file with audio and video already combined (usually in 720p).

You can use that way too. Graphical way is available also.

You should check which formats actually exist for a specific video. The format 22 might fail in many cases. Moreover 22 provides poor audio. So try first:
yt-dlp -F <URL>

And from the listing returned by the command select the appropriate format code (or combination of audio and video format codes), e.g one of the following:

yt-dlp -f '137+140' <URL>
yt-dlp -f '136+140' <URL>
yt-dlp -f '135+140' <URL>
yt-dlp -f '134+140' <URL>

Avoid any formats marked as VP9 unless your hardware doesn’t support this codec already, otherwise it will easily outpower your CPU, since then the video must be completely get rendered in software on your device. Most hardware around still doesn’t natively support VP9, so it’s a good idea to avoid it generally. (For learning how your hardware deals with VP9 just observe your CPU load while playing, e.g. -f ‘247+251’, compare it to -f ‘136+140’ or try -f ‘303+251’ and compare it to -f ‘299+140’ and then decide.)

Windows is like a submarine. Open a window and serious problems will start.

Robin,

All this is correct and I agree with you. However, with youtube specifically -f 22 is almost always a complete mp4 file. On old hardware this saves you the process of merging audio+video stream, and on old hardware the semi-hd 720p with mediocre audio might even play more fluidly than 1080p with best audio.
