    I don’t know what these people are doing who seem to claim it’s wonderful. Every single time I have tried to use one, it’s been completely clueless about the problem and wastes my time producing slop. I almost want to keep my code closed source because of how awful it is at generating anything. Maybe they’re just doing very simple web design or something, I don’t know

    I even have started to hate Google and felt like their search engine is becoming very bad. Yandex has been returning more results and Google feels censored and replaced by generative AI answers.

    Sometimes it’s specific to the application. As an example, yt-dlp is redistributed by Canonical, and they usually maintain stable packages, but their versions seem to lag like 6 months. This might be related to their desire for stability, or maybe just align to their release cycle. I don’t know.

    The issue is that yt-dlp needs to be updated more frequently because websites break their methods of downloading, so the version that follows the latest version seems to work better.

    I don’t think using PPA’s is usually recommended, (like in the photo) so I think I would recommend flatpaks first if the developer of the application maintains one themselves. (and you want to follow later releases.) Though, the first time I had to use flatseal to fix an application, I felt like flathub was a failed platform.

    I might add one for scaling. I just don’t use it as frequently as trying to meet a file size limit. The scaling is also much easier to remember

    ffmpeg -i  in.mp4 -vf "scale=600:-1" -an out.mp4

    It does get complicated though, when scaling many videos and images, I’ve used something like the following in the past

    find .  -exec ffmpeg -i {} -vf "scale=1920:1080:force_original_aspect_ratio=decrease,pad=1920:1080:-1:-1:color=black" {}.mp4 \;

    Those were the only two that showed up when I typed history | grep scale.

    after commenting, I also added a new video file resizer.

    It works significantly better than the one I previously posted. It’s also copied from stackoverflow.

    bitrate="$(awk "BEGIN {print int($2 * 1024 * 1024 * 8 / $(ffprobe \
    -v error \
    -show_entries format=duration \
    -of default=noprint_wrappers=1:nokey=1 \
    "$1" \
) / 1000)}")k"
ffmpeg \
    -y \
    -i "$1" \
    -c:v libx264 \
    -preset medium \
    -b:v $bitrate \
    -pass 1 \
    -an \
    -f mp4 \
    /dev/null \
&& \
ffmpeg \
    -i "$1" \
    -c:v libx264 \
    -preset medium \
    -b:v $bitrate \
    -pass 2 \
    -an \
    "${1%.*}-$2mB.mp4"

    The version I have was copied from stackoverflow. It doesn’t work very well, it makes a rough estimate to get the video file size under the set value. As an example

    resize video.mp4 10

    Which then resizes the video to 10 megabytes if possible.

    resize.sh code 
    file=$1
target_size_mb=$2  # target size in MB
target_size=$(( $target_size_mb * 1000 * 1000 * 8 )) # target size in bits
length=`ffprobe -v error -show_entries format=duration -of default=noprint_wrappers=1:nokey=1 "$file"`
length_round_up=$(( ${length%.*} + 1 ))
total_bitrate=$(( $target_size / $length_round_up ))
audio_bitrate=$(( 128 * 1000 )) # 128k bit rate
video_bitrate=$(( $total_bitrate - $audio_bitrate ))
ffmpeg -i "$file" -b:v $video_bitrate -maxrate:v $video_bitrate -bufsize:v $(( $target_size / 20 )) -b:a $audio_bitrate "${file}-${target_size_mb}mb.mp4"

    I’ll probably replace it eventually.

    What does your ~/.bashrc look like? My last change was modifying a playlist command

    spoiler: I explain my last change to my ~/.bashrc file 
    playlist https://www.youtube.com/@YouTube/videos

    or

    playlist /home/username/Videos

    or just from any directory with files

    playlist

    And then takes all the videos found at the url or at the path (including within folders), adds them to a playlist, shuffles them, and plays them from mpv.

    playlist() {
        param=""

        # If the first parameter has a length more than 1 character
        if [ ${#1} -gt 1 ]; then
                param="${@}"
        else
                param="."
        fi

        screen mpv $param --shuffle --ytdl-raw-options-add=cookies-from-browser=firefox --loop-playlist=inf --no-keepaspect-window --no-auto-window-resize
}
    other functions and aliases in my ~/.bashrc 
    alias code=codium
alias files=nautilus
alias explorer=nautilus
alias rust="/path/to/.cargo/bin/evcxr"
alias sniffnet="export ICED_BACKEND=tiny-skia; /path/to/.cargo/bin/sniffnet"

alias update="sudo apt update && sudo apt upgrade -y && sudo flatpak update -y && sudo snap refresh"
alias resize="path/to/resize/videos/resize.sh"

playlist() {
        param=""

        # If the first parameter has a length more than 1 character
        if [ ${#1} -gt 1 ]; then
                param="${@}"
        else
                param="."
        fi

        screen mpv $param --shuffle --ytdl-raw-options-add=cookies-from-browser=firefox --loop-playlist=inf --no-keepaspect-window --no-auto-window-resize
