Sound but no video

Hello,

I was trying to play my video file hosted at http://www.locusfeed.com/videos?id=1332549095958.mov

I have the following configuration
bc.. <div id="container">Loading the player ...</div>
<script type="text/javascript">
jwplayer("container").setup({
flashplayer: "jwplayer/player.swf",
file: "http://www.locusfeed.com/videos?id=1332549095958.mov",
provider: "http",
height: 500,
width: 500
});
</script>



However I only get the sound and no video.

Thanks.

The issue here is actually that videos short in portrait mode on smartphones are not resized properly. You are going to need to re-encode it again – http://handbrake.fr/

Thanks a lot for the response Ethan.

I verified that it works fine when I capture in landscape mode. Is this a bug in the player? I really don't want to re-encode the video if there is a workaround.

Thanks.

Np. I’m afraid there isn’t a way for the player to read in landscape captured files like this. They will need to be re-encoded for the time being.

I recorded a video on my samsung infuse cell phone and loaded the mp4 formatted file to my server. When I entered the video's url in the jw player wizard, I could hear the audio, but could not see the video. I then tried to play the same video in Windows Media Player and then QuickTime...the video played successfully in both players.

Can anyone help me solve this issue? Do I need to encode the video again, even though the phone recorded it in the mp4 format already...

Hi,
I just installed JW player to test.
I have an Amazon s3 bucket, activated Cloudfront and have uploaded two mp4 videos there.

When I embed on my WP site (http://bizstrategies.dk/category/nyheder)
I get sound, but no video. Both videos are H264 AVC encoded.
The current video is 640x480 and so is the player settings.

I am using flash mode, but want to stream mp4 file.

When trying to play the videos in ex. VLC or Windows Media Player they work fine.

Any suggestions?

ALSO... A bit off topic, but how can I protect the source (ex. a default setting in JW to always use cloudfront and then use only filename in shortcode?

Hey there
I've been running into some troubles with the player myself, as evidenced by http://www.loelc.com/watch/
I have tried a variety of ways of presenting the media, and currently have on the site a trailer encoded with H.264 and AAC, found at either of the options below:
http://loelc.com/wp-content/uploads/2012/08/NewPromo2.mp4
http://lchstheaterbooster.org/wp/VideoContent/NewPromo2.mp4
When downloading these .mp4s, I get both sound and video (if poor quality, that's not my primary concern right now), but when using the player, I only get audio, or, in the alternative, I get the message that the video is not found, even though the location it lists is valid. Where am I going wrong, here?
I am using a wordpress theme on a site hosted on ipage, if it matters, and the example page that I've been trying this on, once again, is http://www.loelc.com/watch

I just downloaded your MP4 and inspected it with QuickTime. It is not H.264, it is MPEG-4, which is why you are having the issues with the player. Flash requires H.264 encoding.

Hey,

I'm getting sound but no video. The video was working before however the file size was far to large which was causing slow loading time. So we've been sent a smaller file which i've now uploaded.

You should re-encode it and make sure the audio is encoded in AAC.

So then your encoding is not correct. You should probably re-encode with Handbrake, link is above…

I have a similar problem. The video was an avi file. I converted it to mp4 so I could use it with JW player. The mp4 file plays fine on my computer. But once I put it on my wordpress site, it plays with sound and no picture (a black screen).

@M.Z. – If it doesn’t work on other phones, it has to be an issue with the file itself.

Hi Ethan

I have the same problem of audio but no video. When I first tested this video it ran perfectly. Then for some reason just stopped the video but left the audio playing. The videos I use are all H264 MP4 format with ACC audio. The current video configuration is 640x360 and the JW Player option is set for that size.

Location of the video is http://creativemusicsystems.com/wordpress/

The embedded code I used is [jwplayer file="https://s3.amazonaws.com/cms.promovid/Ml+Teaser+2+Right+Arrow+640x360-2.mp4"]

The original file is at https://s3.amazonaws.com/cms.promovid/Ml+Teaser+2+Right+Arrow+640x360-2.mp4

I haven't updated to my paid version of JW Player yet on this install.

Any clues PLEASE!!!

Ethan,

Just an added comment on my previous post. When loading the page in Internet Explorer I get a message

"The video could not be loaded, either because the server or network failed or because the format is not supported: https://s3.amazonaws.com/cms.promovid/Ml Teaser 2 Right Arrow 640x360-2.mp4"

In Firefox it is just blank.

On your page – http://creativemusicsystems.com/wordpress/

I see code though, not the shortcode from your post above, which is – [jwplayer file=“https://s3.amazonaws.com/cms.promovid/Ml+Teaser+2+Right+Arrow+640x360-2.mp4”]

Why are you using manual code inside of WP instead of using our WP plugin?

Hello.
Ethan, can you please help me?
I have the same problem - sound, but black screen.
But, what's strange - some episodes from playlist are just fine, some not.
All playlist items refer to the same MP4 file, just different fragments (via http pseudo-streaming, using vstart and vend params).

@Ethan, Thank you for your outlined answers here. I've discovered that not all MP4s are equal, and it wasn't until after I reworked the original AVI the client had given me in Handbrake that I got the video with the audio.

Looking forward to your v.6 (for Wordpress)!
