I need to play MPEG-1 files dynamically from a browser. Uploading them to YouTube or converting the videos is not an option.
How can I do this?
I've seen this, but the answers do not apply to MPEG-1. Is there a way to play mpeg videos in HTML5?
The video tag is not working for the file with Chrome:
<video class="fullscreen" autoplay>
<source src="video/test2.mpeg">
</video>
It just displays a black box and stuttering noise/sound. I can verify that the video is not corrupt because I can play it with VLC. I only need this to work on one specific browser (it does not have to be cross-compatible). Plugins are OK too, as long as I do not have to convert the video. Though I'd rather avoid them.
Some browsers don't support older formats in <video> on purpose, to limit number of crappy, legacy, and potentially insecurely implemented video formats on the web.
The only combination that has a decent chance of working is H.264 (MP4) and WebM (or Ogg Theora), so you must convert the video and for good browser support you will have to generate at least these two formats.
The good news is that modern codecs are much more efficient than MPEG-1, so you'll get much smaller files.
Other options may be:
Give users a direct link to the video so they can download it and play in an external player like VLC.
Embed video using oldschool <object> element, and hope some browsers still have legacy plugins that can play videos (but e.g. Chrome has recently removed support for all plugins except a couple written specifically for Chrome's own API).
Use Emscripten (asm.js) to compile an MPEG-1 decoder to JavaScript and decode the video yourself to <canvas>. JS these days is fast enough to pull that off (although it will quickly drain battery of mobile devices, and a poor video codec combined with an extra download of a JS decoder will be a massive waste of bandwidth).
You can play MPEG-1 videos using JSMPEG: https://jsmpeg.com/

Because I dislike Youtube and Vimeo is too expensive, I chose to upload my videos directly to the server at my web host and embed the videos on my site using the HTML5 tag (see photos for the code). The videos play fine on all browsers except for Firefox and I can't figure out why. https://memoriaelinguagrumentina.org/english/saponareseCuisine.html
I've seen several other posts on here asking about very similar problems; however, nearly all are at least 8 years old. I've gone through them as part of my troubleshooting process, but without any luck.
I've seen it recommended here to use multiple video formats (.mp4 AND .ogv) because there is no universal format supported by all browsers. Firefox did not always support mp4, but I believe it does now. So I don't believe this is the root of the problem.
I checked with my web host to see if they have the correct MIME types (see photo).
I cleared the cache on my browser, set the privacy settings to normal, and checked hardware acceleration.
What am I missing?
*note: To save disk space, I'd like to not have to upload duplicate videos in different video formats to the server, ideally. Since Firefox now claims to support mp4, I was hoping to get away with using only mp4.
Firefox doesn't support all video files. They generally support MP3, WebM, Ogg, and Wave containers, and if you are using an MP4 container then it usually depends on the platform decoders for AAC and H.264 audio and video streams. The video encoder format that you are using isn't supported by firefox. You should use supported encoders for your video.
You can find more information here:
https://support.mozilla.org/en-US/kb/html5-audio-and-video-firefox
Your MP4 videos are using H.265 video codec.
You need to have them encoded as H.264 to work in most browsers.
Solution: This means you must re-save your videos as a new format.
The problem is not just Firefox, even Windows Chrome does not play H.265 encoded video.
Things to fix:
Re-encode as H.264 (use High or Main profile for better compression-vs-quality output).
Re-size your videos (when doing re-encode). 720p should be okay for demos/intros. You don't need a large 3840 x 2160 pixels video showing inside a small 672 x 398 pixels box.
Your file size is not good. 286 mb is too much data loading for just a mere 6 minute video.
I have some trouble getting my .mp4-videofiles working. I have edited my .htaccess with the necesserary addTypes, right html5-video-tags ect, but still some of them WON'T show!
I have now tried converting them from .mp4 to .mp4 wich made some of them work live on web.
But heres the real issue that i really can't figure out why it is so:
All my videoes works very well in both MediaPlayer and VLC, BUT, when i lay them on my website, the videoes won't work. I have tried access them via a direct link and the "corrupted" ones won't work while the working ones works.
What it tells me is that i have the wrong MIME-types (No video source found with the supporting MIME-type) - correct translated? ;)
All videos have the same video-html-settings:
<video width="300px" height="168px" preload controls>
<source src="path-to-video/video.mp4" type="video/mp4">
</video>
What is wrong?! :S I'm have no experience at all in videoes and Google comes up with nothing, than i can use some weird looking "ConvertThisToMP4" or "LetMeFixYourMP4"-programs...
Hope you guys will help me or lead me on the right way :)
Sorry for my bad english...
mp4 for web and mp4 for playback in VLC are different things. You'll get different mp4 video support depending on your web browser, though most modern browsers will handle mp4 in some way.
mp4 is a 'container' format, and as such can contain video compressed with many different video and audio codecs. For an mp4 video file to work in a web browser it needs to be encoded with the h264 video codec and AAC audio codec. Some browsers are even more specific and require videos to be encoded with 'baseline' h264 which uses a simple/fast to decompress version of h264 (this is generally for mobile browsers).
You should have a look at your video files using a media inspector to check what the codecs are for the videos. in VLC you can do this from tools->media information then choosing the 'codec' tab.
You can use handbrake ( http://handbrake.fr ) or mpegstreamclip ( http://www.squared5.com ) to recompress the videos to h264/aac/
As an aside, In your HTML you don't need the px values in the width and height tags, inside HTML all size values are assumed to be px, it's only in CSS you need to define the unit.
I am planning on video upload capability on a public website.
I am not going with Flash instead going with HTML5 using MediaElement.js
My goal is to make sure that processed videos play on browser and all smart devices
I used to convert uploaded videos to flv file to play using flash.
I will use FFMPEG to convert uploaded videos to the target format.
My question is how many different format do I need to process\convert the uploaded files?
You will need at least 2 for the HTML5 video element. You need to supply a H264 and either Ogg or WebM. See Wikipedia for the supported codexs.
I have never used MediaElement.js but it look like they can work with either of the two formats in browsers that don't support the element.
if you want to play everything via HTML5 then YES, you do need 2 video-files for each video, as explained by Maurice.
BUT: You could use the Flash-fallback and only use mp4 videos (MEJS will take care of Flash). That way it plays on iOS, many Android devices and chrome, safari and IE9 via HTML5 - Firefox and Opera users will see the Flash-player.
Can I click on some time and eventhough the video is not downlaoded till that time and the video starts playing from the time I clicked?
If yes, what would be a better option for viewing streamed video- HTML5 or flash player like JW player? WHich one will have less lag?
HTML5 browsers generally don't support this, however I believe the video tag in Safari will work with the Apple HTTP Streaming format for this functionality. For something that works across all browsers, Flash Player can do it using either RTMP streaming or HTTP Streaming (either with our without OSMF to support this). Probably the easiest place to start is with OSMF, which supports both RTMP and HTTP streaming of video.
I have tested this with Firefox and Firebug and while you can "seek" to a point in the video without having to watch video preceding the point you wish to seek, this still causes the entire video file to download.
Indeed, each time you seek in Firefox 4, the entire video downloads.
This may change and improve as HTML 5 video implementations become more mature and may differ based on the actual browser being used.

Our company is making a mobile version of our website. We have several product videos we want to show on the mobile version.
When I try to use
video
I get sound playing but a black screen on my htc incredible android os phone.
I'm thinking that the video is playing but in a different browser window. I need it to display all in one window without having to switch to a different window.
I tried the html embed tags and get no video or sound at all, from what I've read these tags are not very realiable cross browser.
I also just tried the html5 video tags below. I get an icon identifying that it's a video file but it doesn't play.
<video src="video.wmv" controls="controls">
your browser does not support the video tag
</video>
Is there a special format the video file needs to be in? Should I be using the href or embed tags, what other options do I have?
If it helps to know, I'm using the mobile doctype on my webpages.
Thanks
The video format you need to send to the browser varies by browser. Firefox supports Ogg Theora, everybody else seems to support H.264 in an MPEG-4 container (MP4 file.)
See here for an example: http://html5demos.com/two-videos
In any case, WMV won't work.
Android doesn't support the WMV format normally. Here is a list of the supported formats:
http://developer.android.com/guide/appendix/media-formats.html
If iPhone/blackberry/etc don't have a format in common, you may need some javascript magic based on the user-agent to choose which file to embed.
I've found a simple solution to my problem. YouTube. Upload videos on youtube that need to play on your mobile web site and they work. PERIOD.
No fuss! Just copy the embedded URL from the YouTube video page to your mobile page and your all set to go.
I'm not exactly sure how YouTube makes the videos compatible.I'm guessing when uploading the video it's automatically converted into several formats so that the right codec / container is played based on what smart phone is accessing the page.
This list is not extensive and I'll probably think of more later, but comment if you can think of any more advantages or disadvantages of using YouTube for mobile videos.
Advantages:
++ YouTube is universally accepted amongst most major smart phones (therefore your video should play!).
+ If you have limited bandwidth you don't need to worry about wasting any bandwidth of your own.
++ Easy to setup, little to no configuration (setting video resolution). It just works! (encapsulation...)
Disadvantages:
- YouTube symbol during video play back
- It's not hosted on your hosting service. May not be tracked by some analytic services. (requires custom tracking? onclick java-script event?)
- YouTube bandwidth may not be acceptable for smooth replay? (although from initial video viewing bandwidth seems acceptable (minimal buffering...), but not confirmed...). Probably mostly dependent on the cell phone 3g / 4g connection quality.
- limited video file size / resolutions? shouldn't be a problem because you'll want a lower quality video for smart phones.
I would like to know exactly how YouTube make it's videos compatible with smart phones so if necessary I could host the videos myself, but for now this seems to be the best choice.
