• Trouble getting HTML5 vidio to play, in Firefox 33

  16 janvier 2015, par Randy

  I’m preparing to update some old pages to HTML5, and was surprised to see that it worked in Chrome, but not the latest Firefox (v.33.1... also tried v.32). What is odd is this... In Firefox it actually WILL play IF you "coax it". If you move the video position slider to someplace beyond the start (about 5 seconds in) and THEN click play, all is well. Further inspection showed that when I click play, the file pointer was jumping to the end of the file leaving my "poster" photo intact, leading the viewer to think there is nothing else they can do. If, however, you manually move the pointer back to anyplace beyond the first couple of seconds of the file (really !), and THEN click the PLAY button, FF will play the rest of the video fine.

  Sometimes i think that to the more technically minded among us, the universe doles out the weirder problems, while God laughs.

  I’d suspect video file corruption, but all my conversions were made with the very reliable ffmpeg utility, and tested with VLC. Again, it works fine from Chrome, which supposedly uses the same video format. Here’s a link...

  FF will play the older type ogv files, so if this is one of those things where FF, now at version 33 is at fault, I’ll have to detect the browser and write the order myself with a document.write(). But it would be nice to know if there is a more straigh forward solution.

  Note that I have tried adding the mime types to my HTACESS file. But the fact that the behavior is the same when point my browsers directly the file on my local machine, makles me doubt that is the problem.

• Play video files online sequentially without delay/buffering between videos

  26 février 2015, par Marko

  Is it possible to play video online that’s made of two or more video files ?

  Since my original post wasn’t clear enough, here’s expanded explanation and question.

  My site is hosted on Linux/Apache/PHP server. I have video files in FLV/F4V format. I can also convert them to other available formats if necessary. All videos have same aspect ratio and other parameters.

  What I want is to build (or use if exist) online video player that plays video composed of multiple video files concatenated together in real-time, i.e. when user clicks to see a video.

  For example, visitor comes to my site and sees video titled "Welcome" available to play. When he/she clicks to play that video, I take video files "Opening.f4v", "Welcome.f4v" and "Ending.f4v" and join/merge/concatenate them one after another to create one continuous video on the fly.

  Resulting video looks like one video, with no visual clues, lags or even smallest observable delay between video parts. Basically what is done is some form of on-the-fly editing or pre-editing, and user sees the result. This resulting video is not saved on the server, it’s just composed and played that way real-time.

  Also, if possible, user shouldn’t be made to wait for this merging to be over before he/she sees resulting video, but to be able to get first part of the video playing immediately, while merging is done simultaneously.

  Is this possible with flash/actionscript, ffmpeg, html5 or some other online technology ? I don’t need explanation how it’s possible, just a nod that it’s possible and some links to further investigate.

  Also, if one option is to use flash, what are alternatives for making this work when site is visited from iphone/ipad ?
