C++ "ASCII" Video Player Demo - Bad Apple

Source code: github.com/nat...
I still need to implement audio support, I had to edit the music in for this video.
I wrote a simple terminal video player using avformat, avcodec, avutil, swscale and pure C++20. It's still a bit rough around the edges, but it works most of the time.
I recommend watching this video on a high resolution monitor to avoid graphical artifacts from dithering.
Sorry about the shitty audio quality, I am still tweaking kdenlive settings.
Yes, I know. This is not true ASCII, since I use UTF-8 braille dot characters with a special font. :)

Damn Moiré patterns ruining my thumbnail 😠

"What is your favorite video player?"
"My own."

I love how bad apple can be on everything

[@Moeshi]

Omg.. it is good, an art of code :v. Even is black and white I know the whole story lol

[@hypercmdcataclsymco-founde188]

fancy!

[@MrThomas20121]

nice

[@ENRAEGE]

Let's make a comment for possible algorithm.
Still a really nice, smooth animation. Did you speed it up or is it real time?

[@NattyGfx]

It can just enough keep up to be real time, I tried 640x360 pixels, but it struggled to stay in sync. WIth further optimizations, I think I'd get another 50%-100% characters out of it.

@@NattyGfx I think this would be a perfect candidate for multi threading. That should get a lot of work done faster. There's also a faster formula for calculating relative brightness from pixel RGB. Also I don't know if GPU acceleration is possible or of any benefit for encoding to ASCII but those are some ideas since there is no source code yet :p

[@NattyGfx]

​@@Apollyion Thanks for the input. I already decode the video on a different thread and converting from RGB to luminance is handled by swScale. My part of the code mostly consists of image resizing, ordered dithering and a wrapper around avformat/avcodec.
I think the biggest bottleneck right now is pushing all characters to the screen.
I just haven't had the time to finish this project yet as I am busy work and other projects.

[@Apollyion]

@@NattyGfx It's really amazing the work you've already finished. I hope to see more of this project one day!

[@NattyGfx]

Thanks!

[@JohannYuumi]

I got no idea what to comment.

[@MetinCloup]

if you watch 144p it seem no ascii character and awesome

[@namesurname6645]

Please share source code soon as possible.

[@NattyGfx]

Actually happened to remember this project today, added it to the description

[@deezusstudio2232]

I still wait turtorial

[@NattyGfx]

I'll try to get back to this at some point, but it's mostly code anyway. If you wanna try something that actually works, I think VLC (?) supports ASCII art output?

@@NattyGfx thx

[@deezusstudio2232]

@@NattyGfx damn, I thought u used read file to do that lol, Is that open cv?

[@NattyGfx]

@@deezusstudio2232 It uses libavformat and libavcodec, it's basically what ffmpeg uses under the hood.
