I have created a webm video file with transparency with ffmpeg out of a series of png files. Then I add the audio track again in ffmpeg (I have tried both the opus and vorbis codecs). When I play it in the Movies & TV app it plays just fine (audio and video). In windows media player only the video plays. In html (inside a video tag) the video will play if it is set to 'muted' but if it is not muted it doesn't play.
I am not sure what is going on. Does anyone have any insights. Do I need to run the audio from a seperate file?
Thanks, Kate
We are working with a development company to create a program that records videos and then uploads them to a server. Then, on our website, users should be able to view the videos.
Here's the issue. As far as I understand it, .MP4 is the only video file format that can be played in any browser. However, the other development company claims that they will deliver the videos as .MKV video files and then all we have to do on our website is re-wrap the videos or something so they will be playable. I do not understand how that works, and they were being very condescending when I asked for clarification.
The videos have to be able to be played in any browser, and I would rather not have to use any special plugins to convert the videos before playing them.
Please help me understand what they expect me to do.
MP4 and MKV are file formats or wrappers that hold multiple media streams (typically audio and video). The wrapper (MP4 or MKV) tells you very little about the actual audio or video format.
Common combinations are MP4 with AVC video and AAC audio or MKV with VP9 video and Vorbis audio. But you could also do MKV with AVC and AAC.
Rewrapping MKV (AVC/AAC) into MP4 (AVC/AAC) is pretty straight forward and does not require a transcode.
I'd guess that MP4 with AVC video and AAC audio is likely the best cross platform combination at this time.
But delivering video over the internet to a browser with varying available bandwidth - can be tricky and may required multiple different quality levels of the same content.
I've got a mp4 file with one video track and several sound tracks. When i try to open the file in in HTML5 it only play's audio track one. Is it a way to override the the web player to play all sound tracks at once?
I have had a look at a couple of players like Flow Player, JW Player and a couple more but I can't get it to work exactly in PHP code.
Is there any way to play FLV within HTML Video Tags?
I know MP4 and OGG files will but the thing that I am working on will produce an FLV file.
You should look at video.js from www.videojs.com I have been using it streaming live video feeds. It mimicks the video tag like this:
<video id="example_video_1" class="video-js vjs-default-skin"
controls preload="auto" width="640" height="480"
poster="http://video-js.zencoder.com/oceans-clip.png"
data-setup='{"example_option":true}'>
<source src="rtmp://localhost/live/test" type="rtmp/flv">
</video>
Works very well for me.
You might consider using some other players that are able to play FLV files; Known browsers (Chrome, Firefox etc...) are not able to run FLV files untill or unless you use some kind of flash player.
If you are using PHP, you might want to use a flash player! Use Adobe Flash Player, don't be shy! YouTube and many other websites use it.
You can also try to stick to the flayers you have already tried.
You can convert videos to MP4 or format of OGG. So that every browser can play the video file using the HTML5 <video></video> tag.
But Remember: Each browser has its own limitaion for playing a video file; you can read browser support here: Mozilla Developer Network
Play it with Flash. I think it is the only way: http://css-tricks.com/forums/topic/how-to-play-flv-in-html5/
You can do it using flv.js or via MediaElement.js (that will use flv.js underneath), although the support is limited to FLVs that contain H.264 video with AAC/MP3 audio.
Use MediaInfo software or your favorite video player to check what codecs are used in your FLVs.
And if you have H.264 + AAC inside, you can also convert it to MP4 losslessly, without reencoding:
ffmpeg -i input.flv -codec copy output.mp4
Technically speaking the HTML5 video specification is codec/protocol agnostic so one could imagine support for flv files could be possible. Problem is: none of the major web browser has implemented it (probably because flv is a proprietary container from Adobe). You will need a flash component to play it back. Either one of the players you mentioned or if you are looking for a standalone free flash player try strobe from Adobe. You can try it here.
If you can produce .f4v files you may have success in renaming them to mp4 and then try and play them in an HTML5 video tag.
I am developing an Audio Player application in Adobe AIR with Flex SDK 3.2. I wanted to know if i can play songs in other audio formats?
I think Flash Player can play AAC but not AAC+. All the radio stations are using AAC+ because it is updated than AAC. Let me know if I am correct
Although Adobe's site says, Flash Player 9 Update 3 onwards supports AAC and MP4 also, i am not able to play them when i tested. So i think its safe to say that, Flash Player will only support MP3 and WAV files to play sounds.
