Iam less familiar with doing this kind of thing on an iPad. The problem with video is there are many, many encoding components out there. These then get bundled together in a container such as mp4 which admittedly limits some variants but some make it in. Then the app you are using to play it (and you are using an app even if it is just Apple's) has to contain a decoder for the type of audio or video you are seeing. Apple is somewhat limited, particularly with them dropping older video codecs recently (at least in iMovie they did). VLC is pretty well trusted and has the advantage that it can play pretty much anything. At least then you could see if the issue was with the payer you are using or if it is with the file itself. If it's with the player then you don't have much option since Apple doesn't let you mess with app capabilities, particularly not on a iPadOS or iOS. Then your option would be to use an app to recode to a mroe friendly version. You'd lose quality and at this stage I particularly am not familiar with how you'd do this on an iPad. Computers have a LOT more flexibility in this regard.
Note that mpeg-4 != mpeg-4 (or rather mpeg-4 isn't a codec but a standard describing how a conforming codec should behave and/or a container format that binds different video/audio/subtitle streams together, every single video on a page is a "MPEG-4" container) and the codec in question is an older implementation of the standard. You mostly see the newer H264 or newer in the real world. Both are mpeg-4 (part 2 and part 10 respectively)
Thanks for the answer.
Actually test page was run by me, to be 100% sure.
I have MPEG-4 video to watch because of my work.
My second desktop with Ubuntu and same Firefox version on the board does not have an issue with these videos.
This isn't "mpeg4", it's xvid (the super-dated MPEG-4 ASP codec) in an avi container - which is typically not supported by html5 implementations.
Since your "test" page is actually jquery did you check that the generated result is actually the same across browsers and doesn't utilize other html tags on the ubuntu system?
I am playing video in mat-video and video tag, but none of them playing video which has video codec type as mpeg 4 (simple profile)however H.264 codec format is playing
fine.is there any way to support mpeg 4 codec in video tagI tried :
We can not play video with 'mpeg-4 video' codec . For that you will have to convert video codec to 'h.264' from any converter.I had also faced similar issue and I managed to convert this video through AWS media convert service.With AWS media convert SDK , I converted around 500 video by submitting batchJobs via nodejs script using their SDK.
MPEG-4 is a widely used video file format that is known for its high-quality video and audio compression. Given its usefulness, you likely have MPEG-4 videos (often in an MP4 container) and need a way to enjoy them. Note that MP4 is a video container, and MPEG-4 is a video compression format that is often used within an MP4 file container. Get more info. Fortunately, MPEG-4 video and MP4 video files work in DivX Player.
High Compression: One of the primary benefits of MPEG-4 video is its high compression capability. This means that MPEG-4 videos can be compressed to a small size while maintaining high video and audio quality.
Multi-platform compatibility: MPEG-4 video is compatible with multiple platforms, including desktop computers, mobile devices, gaming consoles, and smart TVs. This makes it a versatile format for video content, as it can be played across different devices and operating systems.
Additionally, if you have a video that you want to convert into an MP4 file, DivX Converter (also part of the free DivX Software suite) is a simple and quick solution. Read up on how to convert a variety of video formats into MP4.
Get high-quality surround sound when you buy the DTS-HD Plug-in for DivX Software (or DivX Pro). Enable the conversion and playback of DivX video with DTS-HD audio, including HEVC video content up to 4K. The DTS-HD Plug-in allows you to convert and play videos with DTS audio tracks for studio-quality sound. Whether enjoying entertainment at home or on the go, DTS aims to provide the finest audio experience possible no matter what device you are using.
On top of all the features listed above, there are some additional advantages that come with purchasing DivX Pro. In DivX Converter, you can unlock custom encode settings, set B-Frames, modify settings with Target Quantizer and other super nerdy options. In DivX Player, you can enable HEVC 10-bit playback and more.
Enabling Cloud Connect (included in DivX Pro) allows DivX Software to sync videos from Google Drive and Dropbox. With one easy step, you can download and upload videos from multiple cloud storage accounts in DivX Software. You can sync videos without the hassle of having to download extra apps or open multiple browser and file windows.
Buying Video Pack (or DivX Pro) allows you to convert unencrypted MPEG-2 and VC-1 files, so you can backup your Blu-ray or DVD discs. If you have stacks of discs to convert to digital files, or want to cast Blu-ray or Windows Media to your TV or gaming console, Video Pack is your solution.

I think part of me not being able to find the right package is that I do not know which repos are supposed to be used with RL. Can rpmfusion repos work with RL? Centos 8 repos? RHEL 8 repos? Is there a list of repos that are supposed to be used with RL?
Powertools used to be the name of a CentOS repo, I think, now replaced by crb. On alma at least, you can enable it with
sudo dnf config-manager --enable powertools.
The rpmfusion free and unfree repos have ffmpeg and mpv. Pretty sure those will cover most things you want to play.

Around the time that Spotify implemented the world's crappiest "update" (you know, the one that got rid of ctrl + f and other awesome features) I was plagued with a problem. Not long after that awful update another was implemented and everything went downhill. I just shrugged it off for a while thinking "Oh it'll get worked out in the next update." Well there's been a next update and I'm still screwed. Today I did everything I could find to fix this problem. I updated iTunes, repaired QuickTime 7, uninstalled and reinstalled Spotify. Here's where it gets interesting. After I uninstalled, rebooted my computer got back on and reinstalled, for just a minute, one sweet and glorious minute, the problem seemed solved. Then it unsolved itself. Why won't my MPEG 4 files play anymore?!?! They played fine a few weeks ago before Spotify did all this update crap. This, plus all the features that have been removed recently is really pushing me back towards iTunes.
Based on this webpage, and inspecting the codec of the video using the VLC media player, it looks like the issue is that Quicktime does not support the the H264 - MPEG-4 AVC (part 10) format that the video is saved in.
A common issue with ffmpeg encoded videos is the pixel format: Why won't video from ffmpeg show in QuickTime, iMovie or quick preview? - Ask Different . However, with your settings VideoIO should use yuv420p which should work in QuickTime so it would be good to have more information:
The default also does not play in Firefox, and FF tells you it is a bad encoding (the error message is deliberately wrong and WontFix), so you fiddle with the encoder options instead of target_pix_fmt
From Samsung official website, we clearly know that Samsung TV is only compatible with MP4 in H.264/MPEG-4 AVC video codec and AAC audio codec. If your MKV/AVI files are encoded with other codec, Samsung TV will not play.
