Simply love this plug in!
I looked for an answer to this in the forum but didn’t see it addressed specifically.
Playback was working across the board in all browsers and platforms I’ve tested with one exception. The iPad. I get the html5: Video file not found.
I think the iOS is 5.1.1
For Safari on that iPad:
Apple WebKit 534.46
KHTML, like Gecko
Has this happened to anyone else, and what might I try to hunt down the problem.
The video file might not be compatible with iPad. MP4 can contain different streams. Please use the video checker (the message which appears in the top left corner of the video) to check the video properties and use the “Send to Foliovision” button to send us a report.
You can try to re-encode it into MP4 using a free software called Handbrake, we absolutely recommend you use the original uncompressed file for the conversion, for maximum video quality. Our article about video encoding is here, together with recommended Handbrake settings: foliovision.com/wordpress/plugins/fv-wordpress-flowplayer/encoding
as you are our licensed user, we tested the videos on your site right away.
The /windows-8-tutorial and also /windows-tutorial05 both play fine on both iPhone (iOS 6.1.3) and iPad (iOS 5.1.1)
Please visit this site and copy over the “Your User Agent String is:” information here: http://whatsmyuseragent.com
1) Have you checked some other videos or is it just /windows-8-tutorial ?
2) Are you logged in or logged out when this happens?
3) What happens if you open the video URL directly in the iPhone (you would have to copy it from post editing)?
It looks like at some point one of the updates to my screen recording
software changed the format of mp4 export slightly. Though, with the
tools I have here I am unable to determine how as the files seem to be
in the same format.
I was able to get videos playing again by re-encoding them with
Handbrake, I have e-mailed Blueberry (screen recording software) to ask
them what has changed.
I will use the Send report function to send you details about one of the
videos before I replace them today.
At this point I am totally stumped, here is what I know:
1) None of the mp4 videos I have uploaded since August 29th will play on
the iPhone 3GS with FV Flowplayer.
2) Blueberry software sent me a link to their old version of the software
and I re-encoded a video with that, but it still doesn’t work.
3) I encoded a video using the recommended settings in handbrake, but it
still doesn’t work. I somehow managed to find some settings that would work last night, when experimenting with Handbrake, but this morning I can’t for the life of
me get a video that works on the 3GS.
4) I have tried 2 different 3GS phones, the videos do not work on either of
5) I have tried clearing cache and cookies in Safari on my 3GS, it made no
difference. I’m also logged out of WordPress on my iPhone, I don’t have my WP
credentials on my phone.
6) If I copy and paste the video link directly, Safari says “Safari cannot open the page because it is a local file”. If I place the offending video file in my Dropbox however, then attempt to open it directly on my iPhone from my Dropbox, it DOES play.
I think we can eliminate this being a problem with my encodes, but I
cannot explain why suddenly newer videos don’t work on the 3GS. I know a
lot of people still use this phone, so I would be very grateful if you
I just did a bunch of re-encodes with Handbrake and they are not playing either, but they are only having problems on the 3GS.
This is far from solved I’m afraid :(
could you please let us know what your user agent is for these iPhone 3GS phones? I posted the instructions above.
The thing is that iPhone 3GS might be using either iOS 3 or iOS 4, both are quite old now. That leads us to some recommended encoding settings for these devices – I read that iOS on older iPhones for older devices has a resolution limit of 640×480. Also, what .h264 profile did you used? You might need to use baseline profile.
However our ultimate goal is to detect the user agent/connection bandwidth combination and allow you to set a different file for mobile/low-bandwidth devices and for the rest. That way the videos would be fast even on mobile devices with slow connection.
I have found out at least where the problem is –
On my test page there are three videos, each encoded with the exact same
Handbrake settings. The only difference is the top one was resized to
640×480, the middle to 800×608 and the last one left at its native
1024×768 size. Only the top most video (640×480) plays on my 3GS and on
my girlfriends 3GS (both on iOS 6).
Now it makes sense why my older videos worked, because it was Windows 8
that moved the minimum screen resolution up to 1024×768 and so my
encodes moved up in size too!
So, can your team investigate why larger size videos fail to play on
some iOS devices like this? It shouldn’t be a problem for the device to
just resize the video to fit.
I am getting an Apple fanatic friend to test the same page on all his
devices tonight and will report back.
Did you get my latest e-mail with the video test page? It seems that the iPhone 3GS is rejecting videos that are > 640×480 in size so you could be right, but they DO play if played directly on the device. I used h264 profile – Main.
If I encode two separate videos, and put the second, smaller video in the “mobile video” box when adding the FV WP Flowplayer shortcode, would that work?
Anyway, here is the user agent string from both phones (identical), were are on iOS 6
Mozilla/5.0 (iPhone; CPU iPhone OS 6_1_3 like Mac OS X)
AppleWebKit/536.26 (KHTML, like Gecko) Version/6.0 Mobile/10B329
Mozilla/5.0 (iPhone; CPU iPhone OS 6_1_3 like Mac OS X) AppleWebKit/536.26 (KHTML, like Gecko) Version/6.0 Mobile/10B329 Safari/8536.25
Thanks for the help, looks like we’re getting to the bottom of this.
interesting, I found out about the same issue above.
What you can do is to use “mobile video” field of our plugin. Enable it in Settings -> FV WordPress Flowplayer -> Post Interface Options. Then in the shortcode editor you will get a special field for mobile video.
Even if the later iPhones’ screen is in reality 640x960px, it’s true size is calculated as 320x480px as it’s the so called “retina” display.
Fantastic! It feels good to get to the bottom of the problem. I just tried that on http://www.top-windows-tutorials.com/windows-8-tutorial/ and it now plays on the 3GS. FV Flowplayer rocks :)
Feature request – Have the video checker warn the user if they only provide a video that is greater than 640×480 size that it might not play on some mobile devices.
Sorry I don’t think I was clear. What I meant was, have your video checker (the thing that is only shown to admins) show a warning if the video will be too big to play on iOS and no alternative is provided (like it does when moov atom is wrong for instance). I did not mean a warning to the website visitor.
I think that would be a good feature to add, but obviously I don’t know how much work that would be, just a suggestion is all.
Thanks again for all your help,
the plugin no longer displays videos on Iphone. The message “hml5: video not found” appears. It works well on Android and PC. In the past days it also worked regularly on the iPhone.
