Me opening /dev/urandom as a raw video stream to watch some nice relaxing RGB static.
Weird. Anytime I do that I get Rick rolled.
FFmpeg enters the chat
Yeah, guess where vlc gets all that muscle…
I thought it was libvlc that covers that but no, it is indeed libavcodec which is part of the ffmpeg project. Does anyone here know the relationship between libvlc and libavcodec?
libvlc uses libavcodec
VLC relays on ffmpeg for a lot of video decoding, as do lots of other media programs. Go look up the legal notice on your TV and there’s a good chance the ffmpeg licensing information is in there.
If you look up the dependencies or legal notices for anything that does anything related to video, audio or maybe even images, it’s very likely that it uses ffmpeg in some way.
FFmpeg is one of libvlc’s backends. A lot of stuff vlc can decode without calling ffmpeg.
Followed by MPV doing the same
Whenever someone ask me media player for Linux I suggest MPV but for Binbows I suggest VLC. I don’t know why?
IIRC VLC on Windows uses it’s own included ffmpeg libraries for decoding so you don’t need to mess around with Windows codecs.
I’m in the MPC-HC gang on Windows. Just so much more practical than other players. The main selling point was that full-screen the controls go away once you move the cursor off them, it was amazing. And no waiting for subs to be processed like VLC had to back then, never turned back so don’t know if that is still a thing.
the main selling point of mpchc is madvr. there’s basically no other competitors that utilize the GPU to make the media your watching better on the same level as madvr.
BE > HC
I use mpv but the configuration is a big pain. Just try overriding a subtitle font in mpv, there are config files to change that don’t even exist by default and they live in different places depending on mpv version and it’s a huge mess.
I still do it because it’s lightweight and for some reason has better performance for me than VLC.
I do the same because VLC has an installer on Windows while MPV you have to manually extract from a compressed folder and then run the install script from command line
My download came with a .bat executable
I want installers to die, portable is the future
MPV.net for Windows is great.
ffplay
I once thought of a movie while coughing into a microphone. I opened the recorded cough with VLC and it played the movie.
You don’t even need to cough with the right setting on. That’s just a safety feature for the uninitiated, so that they don’t submit freaked out bug reports.
My only regret is that I have but one vote to give this amazing post. Bless you, friend, a real treat.
I just discovered something that VLC REALLY didn’t like to play. A 4K50fps JPEG2000 YUV444 12bit lossless ~48 GB video that was only 1 minute long.
To be fair the bitrate of the video is insane at ~5700 Mbit/s. The bitrate is so insane that you should really consider using an NVME drive for playback.
MPC-HC could kinda play it but only with extreme stutter and lag. My CPU (Ryzen 9 5900x) was completely maxed out.
I think you need hardware acceleration for a video like this.
Forget playback. How was that video file recorded? How do you even store data that fast, let alone encode it?
You can read more about why and how it was made here: https://www.svt.se/open/en/content/
The only place I could find where I could kinda play the video is inside Davinci resolve, but it doesn’t look how I would like it to. Probably due to the apparent lack of HDR support in Resolve on Windows (unless you have a separate TV connected to the PC somehow.
Ohhhhhh. It’s a video decoder torture test. “If your app can play this it can play anything” sort of deal. That makes sense.
Also makes sense that VLC puked.
I think it’s more of a test for encoding, not sure if you are really supposed to try and play it in an app.
1 Terrabyte RAM with a 64GB RAM Drive perhaps?
Vlc has hardware acceleration afaik. I think its more a case of the ffmpeg codec not supporting it yet because what the actual fuck haha
Yeah, I think it’s a good idea to try ffplay if VLC (or mpv) fail.
I get similar results with ffplay compared to MPC-HC. I unfortunately haven’t been able to get proper hardware acceleration to work anywhere.
Or maybe it does work and it’s still bottlenecked by the CPU somehow.
Haha, that’s fair 😂
I think you need hardware acceleration for a video like this.
ok but why would anyone have a video like that
You can read more about why and how it was made here: https://www.svt.se/open/en/content/
It’s basically intended to test encoding and stuff like that.
Maybe some kind of super slow motion high resolution type thing?
Yeah I could definitely see this for slo-mo and data recording in an actual laboratory setting that requires it to be as accurate as humanly possible. Idk if this is a standard though I’m not a scientist.
but if you’re gonna watch it in slow motion anyways then why isn’t it saved as a slow video that is much longer?

Where can I try this

I downloaded “natural complexity” or something like that. Unfortunately FTP downloads are limited to 100 Mbit/s so downloads can take a while. Imo they should make a torrent.
Certain programs can do multithreaded downloads on ftp servers. Winscp is one that can do it. Idk about other software
JPEG2000 = not lossless
JPEG2000 supports both. That’s why I specifically said that the video is lossless
Right! Sorry, I assumed this was regular JPEG
VLC is not script-frendly. mpv is the goat. You can even watch videos from YouTube and maybe from somewhere else.
I was team VLC for certain things it could do, and then I found that MPV could do all those things and more. Crazy how versatile it is.
vlc can even play incomplete video files - it’ll just play the parts of it, that will play.
It’ll even play videos that are actively downloading
^ Found a fellow old school torrent user 😆
The cool part is vlc can act like a video downloader, screen recorder, and media converter. It can also stream a video over the internet
The swissknife of digital video.
The every thing tool for media, now we just need a video editor XD
mpv + vlc
VLC: it can do anything media related. I wish iTunes can do this without being so bloated.
VLC is nice, but same as SMplayer or Mplayer, it can`t download a video, but record it in streaming. I used VLC before, but VLC lacks in speed, it’s very slow compared to the mencioned.
The trick is you get the stream url from vlc, then load it up in a browser to download it fully.
And the dude who maintains VLC do not even make money from it, at all!
He is also an extremly annoyed french guy who has no fucks left to give. One of the maintainers is on an episode of the FOSSPOD and it was glorious
I find VLC really struggles with UHD high frame-rate video.
Is it vlc struggling or your entire PC?
I has one boss who wanted to stream 2 4K60 cctv feeds to his laptop while in the office. Needless to say his laptop struggles with a single 4K I didn’t even bother setting up the second feed.
Run a transcoder in “the cloud” (another PC in the room) and then it’s possible
Another fun use for ffmpeg!
Other video players work fine. My PC is fairly new.
what are you watching that’s uhd and high ftamerate? is is something you made? I’ve never heard of anything releasing like that because yeah, most people can’t play that lol.
Yeah, videos from my phone. Most things aren’t an issue.
Record the video in lower resolution from your phone unless you actually need the high resolution.
I don’t even know what icon is on the right
I think it’s Windows Media player
Relabelled as Movies
MPC: All my homies hate wmp.
There are people who like VLC, but for me personally, MPV has a much cleaner interface, better configuration options, and when it comes to streaming video, MPV absolutely destroys VLC (especially when changing playback speed while the video is playing – VLC has the audio cut out for several seconds and MPV doesn’t, and that’s to say nothing of the MPEG glitches)
I am glad both MPV and VLC exist.
I switched to MPV recently for the same reasons. If it had support for playing disc media it would be the absolute king of video players imo.
It has support for it tho.
If so, then it definitely doesn’t make it as obvious as VLC does. but good to know I suppose
edit: it only plays whatever the largest file it can find on the disc is, no menu / iso support. womp womp
Mpv is better
It runs better, but VLC is much more user friendly
shrugs idk. Vlc has more features. Not sure I’d call it easier.
Tell your parents to set mpv to loop a video and see how it goes
Such beings do not deserve to use computers. We’re talking about humans here, not our monkey ancestors.
Just use smplayer as the frontend for mpv and you’re all set.
I actually found a file format that VLC won’t play, .MJP, yanked off of our network’s security camera system. It requires the security company’s proprietary video player.
what do you see from running binwalk on one of these files?
I don’t know what that is - I’ll have to look into it on Monday.
Very high level: it’s a program to quickly find files within files and it runs on pretty much any OS that exists
VLC the undisputed champ
I was missing Codecs in my Linux install. VLC couldn’t play a single file
Reinstall it.
