How to play html5 video? When is file.m4v file?

I tried several methods, but nobody plays file2.m4v using html5, see screenshot.

But if I use the same file using VLC / Mplayer, it plays the movie perfectly (no problem). Please review the code and details of the file to find the code that it uses:

enter image description here

video.php:

<html> <head> </head> <body> <video preload="auto" autoplay="autoplay" controls> <source src="/var/www/html/video/file2.m4v" type='video/mp4; codecs="avc1.42E01E, mp4a.40.2"'> </video> </body> </html>

Find audio / video codec files:

What else can I use to play this file in a browser? Is there any javascript player available if html5 cannot play it?

HTML5 Video is simply an agreement to play certain video formats with a new element for which browsers will implement their own player. HTML5 does not provide players or anything like that.

You should look for codecs and be supported by most browsers, which, if I remember well, are mostly Theora for Video and Vorbis for audio in an OGG container.

Then I remember that Webkit browsers will support Matroska (MKV) containers, using V8 as a video codec and Vorbis for audio.

My recommendation: provide an OGG file with Theora and Vorbis as video and audio codecs, respectively. Inside there is a backup using the MKV file with V8 and Vorbis, and then, if possible, inside the MPG video file using Mpeg2 and MP2 (could not think of something better) as video and audio codecs. Then, as a last resort, the Flash player plays the FLV video file.

An example of what your HTML looks like:

 <video src="thevideo.ogg"> <video src="firstFallback.mkv"> <object type="video/mpeg" src="secondFallback.mpeg"> <object type="application/x-shockwave-flash" src="player.swf?etc..."> <p>Download <a href="videourl">the video etc...</a><br /> or use a more modern browser to watch online, etc...</p> </object> </object> </video> </video>

Etc ...; -)

In this configuration, most (if not all) browsers should be able to play your video, preferring the most supported (and most modern) format. "Fallbacking" until they find Flash Player.

For tips on which formats to support: see part of the HTML5 video on Wikipedia . p>

Important: In the code, you refer to the path of the absolute file system, which is completely not accessible to the visitor. Perhaps in src you meant /video/file2.m4v .

Try:

 <video id="myVideo" width="300" height="200" preload="auto" src="/var/www/html/video/file2.m4v" type="video/mp4" autoplay controls></video>

Also try renaming the file to file2.mp4

HTML5 is a web standard (in other words, a specification), not a technology, so the phrase "html5 can not play it" implies some misunderstanding on your part. The file is decoded by the browser in accordance with the settings specified in the <video> . It is worth noting that not all browsers and / or operating systems have the same codecs, so first make sure that you can play the video natively.

Firefox, for example, cannot decode anything encoded by the H.264 codec, which, it seems to me, is used in .m4v files (who knows better, please correct me).

Finally, as someone else remarked, your path is most likely wrong. Delete the fragments of the path "var" and "www".

Your html is correct, therefore either the path is incorrect, the file is invalid, or the browser does not support m4v.

  • / var / www / is very suspicious, but as you say, it works with the avi file, so it’s not him

  • Try using the file: http://ade.apple.com/movies/institute2011/hotel.m4v in src. If it plays, your m4v is probably incorrectly encoded.

  • If you use Firefox or Opera, then the movie will never play because they do not support anything other than WebM and OGG
