Droplet for simple VR video ?

I'm sure I'm not the only one person that would Looove Droplet för VRvideo playing - Sales wise - there is thousands of happy
Theta S shooters ( like me ) that would buy KRPANO directly if there was a simple ( droplet ) way to get VR video
Playing on private domains .
Please Please Please.
mp4 would do .

Just pick up the example from the 1.19pre download and change the video files.
Make sure you have an mp4 and webm version.
Sound also possible. (mp3|ogg)
Use handbreak and Miro converter.

Droplet makes no sense in this case i think.

But let me ask,
what do you expect the droplet to do?


Hope it helps!

as Tuur says droplet for video doesn't make sense as for video you don't need to transform your source files ( for panos you have to convert them in tiles ) , so I guess the need is for having a simple code where you can just declare your video file and it works...

This is pretty simple and in the examples you can find it...

I have made a simple droplet for 360 video publishing:

The idea of droplet came up from Keith Martin
on Ricoh Theta FB group.


I understand it is very simple.
to code - butdroplet is sooooo much simpler - as it can handle misspellings -
and for example as Tuur says - Don't forget webm - then I start too Google webm :-)
IN the best of the worlds I would like the droplet to do all that for me ( excluding Google search maybe )
( maybe the droplet could access some web based webm creating service )






Warm regards.


I would say in this forum I'm probably one of the people that struggle most to understand difference between xml and html
But in real life on streets of Stockholm I would say i'm better then 9 of ten :-)

Let me put you this way - it is very simple to speak Polish.
even 2 year old can do it.
( and yes I'm born in Poland so I know )

So simple is very relative term .


The lovely thing with my krpano video struggle is that
Theta S video loooks so much better self hosted then on You Tube or facebook .


I will test Jonathans droplet on my mac ( But he says it is PC droplet )

My guess is that creating 100 % foolproof video droplet would increase krpano sales.
( as Theta S will be sold in tens of thousands :-)

Regarding TUURs suggestions -

Hmmm

Downloaded 1.19 - registred krpano licens in krpano tools.

Looked for " examples folder "
found only webvr folder-

When I open index.html ( on my mac )
I get a still sky panorama with text Look here to start-

This is not what I expected .

File set that works correctly on Jonathans server ( 1.85 ) is what I want
http://www.v360r.com/jann_theta360video_1/index.html





And I got it to work on my own server :

http://www.fotograf.nu/jann_theta360video/index.html
And even as iframe ! which is what I was fighting for !!!

Thanks You Jonathan

Hi Jonathan,

sorry, i thought you had some (more) basic experience with krpano. My mistake.
You could take the video player example from 1.18.5 and update that to 19.pre3
That means new viewer files and plugins.
then include the webvr xml and all necessary graphics etc..
Maybe you need to put keep="true" on some plugins..
That should be it.
Could be simple.
When i have time i can make a quick bare bone setup that you can use as template.
And maybe jonny5alive can make a droplet for that.(i don't need it ).
I can make droplets of course but i don't do ffmpeg... yet..

OK _ i will try TUURs approach -

My test krpano Theta video seems not to work properly
on Note4 and unfortunately Sound doesnt work on iphone 6.

SO the solution is not so good but I'm quite happy with much beter
image quality then YT upload.
So I will fight a bit more .
Maybe 19 pre 3 works better

SO I use the sample videointerface from 1.85 ,
but remove 1.85 viewer folder - by overwriting it with viewer folder from 1.9 rev 3
sound issue must be krpano related as i Can hear sound in the video files...

I've made a bunch of changes to the droplet. A sample output is here:

http://www.v360r.com/tmp_video6/

The settings button lets you choose three different qualities, and I have reduced the file size a lot. I have also used to the 1.19-pr3 pre-release code. It automatically makes thumbnail images too.

I am still having issues with sound though, but I'm sure I'll figure it out.

Also on Amazon Cloudfront here:

Feel free to buy me a THETA S *rolleyes*

Great - so ..
Krpanos own Example Video interface is good ?

I guess not modifications of that are needed -
I kind of miss " fullscreen button " on mobile ....


Then 3 different video sizes / formats are needed - Handbrake or Miro
for webm ?

are output settings invoking problems with sound ?
Anything special that spoils sound ?

Hi,

i made this small gift to share when it helps.
It is a quickly made fusion from the videoplayer 18.5 and the webvr.xml (1.19.pre3).

http://www.virtualtuur.com/krpano/videovr_pack.zip

here an online example
http://www.virtualtuur.com/krpano/videovr/


- put your tour.js and tour.swf (version 1.19.pre3 in the folder.
- put your video files and posters and audio files in the video folder and it works.

To make this example work instantly name all your files myvideo. But you should change that in the video.xml when you want that different.
In the video folder should be:
- myvideo_1k.mp4
- myvideo_1k.webm
- myvideo.mp3
- myvideo.ogg
- myvideo_2k.mp4
- myvideo_2k.webm

and the 2 poster files as:

- myvideo_1k_poster.jpg
- myvideo_2k_poster.jpg

So i guess jonny5alive (Jonathan) can pick it up from here ;-)

Special Thanks to Torsten Hemke for providing and approving the use of a part of his heli flight 360 video!
(this credit textfield and the video's are not in the zip.

Hope it helps!
And don't forget!
The search function of this great forum works very good. First try, search and most important: Want to learn!

Hope it helps,
Tuur *thumbsup*

Thank You Arthur - i try understand things better .-)

Q1 -
"- put your tour.js and tour.swf (version 1.19.pre3 in the folder."

Cannot find it - and I made a search in my krpano folder-
Got hits on some files but from 2013 ...


But for sure I need also to put " viewer " folder from 1.19 pre3 ?




Q 2

n the video folder should be:
- myvideo_1k.mp4 1024 wide mp 4 made by Handbrake or Miro ?
- myvideo_1k.webm Handbrake ?
- myvideo.mp3 - it looks like sound only file - how Do i create it ?
- myvideo.ogg - How to create it ?
- myvideo_2k.mp4 - 1920 k wide I guess
- myvideo_2k.webm - made with handbrake or MIro ?


ogg file is not mentioned in video .xml document ( to be invoked )

and the 2 poster files as:

- myvideo_1k_poster.jpg - is it 1000 or 1024 px wide ?
- myvideo_2k_poster.jpg is it 2000px wide or 1920 ?

Hi,

Q1

well.. did you download the latest krpano 1.19.pr3?
http://www.krpano.com/forum/wbb/index.ph…61294#post61294
You need that of course.. 2013 sounds like 'stone age' in krpano terms.

Q2

i make my prores video , posters and audio files with Adobe Premiere.
Audio file should be exactly same length as video file.
Posters should have same size as video file. Typically the first frame!

I use handbreak to make 1k-2k-4k mp4 files from the prores files

webm and ogg i make with miro video converter.

maybe re-download the zip file again.. there should be the ogg in the xml now. (forget to re-upload)

1k i would do 1024x512
2k i would do 2048x1024 or 1920x960

And..
all this information is all over the forum.
Use the search, read some posts, Google a bit... look some more.. think about things.. have a sleep... try some more...make an example... try again.. search again.. etc etc.. !

Tuur:

Here are some tips with FFMPEG:

%FFMPEG% is FFMPEG binary location%~1 is input video filename

Generate thumbnails:


%FFMPEG% -i %~1 -vf "thumbnail,scale=1920:960" -frames:v 1 video\video-1920x960-poster.jpg
%FFMPEG% -i %~1 -vf "thumbnail,scale=1024:512" -frames:v 1 video\video-1024x512-poster.jpg

If you put a hidden image in your HTML, it will show up as a thumbnail when sharing on Facebook etc.

Make full-sized videos:


%FFMPEG% -i %~1 -vf scale=1920:960 -r 20 -maxrate 2500k -bufsize 512k -vcodec libx264 -ac 1 -threads 8 video\video-1920x960.mp4

%FFMPEG% -i %~1 -vf scale=1920:960 -r 20 -maxrate 2500k -bufsize 512k -ac 1 -threads 8 video\video-1920x960.webm


I found these settings after experimenting work on Apple, which caused problems before.

Lower quality versions for mobile:


%FFMPEG% -i %~1 -vf scale=1024:512 -r 15 -maxrate 1000 -bufsize 512k -ac 1 -threads 8 video\video-1024x512.webm

%FFMPEG% -i %~1 -vf scale=1024:512 -r 15 -maxrate 1000k -bufsize 512k -vcodec libx264 -ac 1 -threads 8 video\video-1024x512.mp4

Hope this helps.

OMG _
webm is killing me - for a project that needs SPEEED -
Exporting webm on mac using miro is so slooooooooooooooow.


I could try installing ffmpeg on my mac- will it make the process three times the speed of miro ?



I talked to sem Video folks I know and they told me that they never bother with webm format as almost everything will show mp4 ...


So how important is it with webm / ogg ? ?


Seriously !!!

Please tell me to skip it ....

Monday, November 30th 2015, 2:26pm

judging by this
http://caniuse.com/#search=h264

webm/ogg seems to be a waste of time ?
