Our aim is to show portait video (vertical orientation in terms of TokBox) without black areas right and leftside after archiving. Now it looks like landscape with black areas on right and left side.
We are using php server and android client for streaming.
Our steps to convert live stream in video on demand through archieving are:
start session
update stream with the parameter layoutClassList = verticalPresentation (php library)
start archieving
live stream is on -> create subsriber and watch the stream. IMPORTANT! The stream has no black areas and has CORRECT presentation on subsriber side!
stop archieving
waiting TokBox upload archieving file to Amazon s3 bucket -> the file ALREADY contains black areas right-leftside. WRONG! (please watch the video on link for better understanding https://s3-us-west-1.amazonaws.com/edtv-dev1-input/46176492/9f26ef23-aee6-42f2-8c51-d8e2685abcc9/archive.mp4 )
processing the file
Are thereabove the correct steps to achieve the goal - get video file without black areas (in portrait orientation)? Are we missing anything?
Is archieving process on TokBox sensitive to horizontal/vertical presentation? is it possible to archive the video in vertical orientation?
UPDATE: What we wanted was not composed, but INDIVIDUAL stream! TokBox creates zip file, but Amazon AWS was able to transcode it and get the correct result both in portrait and landscape orientations.
NOTE: As a default result file on Amazon AWS after Individual stream archiving is *.zip (json + video file in it). The trascoder we used gave us video without sound. So we added lambda that unzipped the file. Now everything is ok, but took a lot of time and headache.

For composed archiving, the only two options currently available for output resolution are 640x480 and 1280x720. Trying to fit a portrait video into a canvas of the available resolutions will result in the video you are seeing.
Possible solutions:
Use the custom layout control [1]: you can override the "object-fit" property to "cover". This may not result in exactly what you want, since the output resolution will still be 640x480 or 1280x720, but the video will occupy the whole canvas, at the expense of cropping the top and bottom part. See [2]
The best solution in my opinion is to use "individual stream archiving", where the resolution will be kept as the original, and you get a file per stream. Please check [3]

How can we get URL within the zip created by opentok which was uploaded in s3

I'm using AWS MediaLive to build and deliver HLS stream of a video file stored in S3. I would like to know how to include squeezeback ads in this HLS stream playout.
Thanks for your post. AWS Elemental MediaLive does not do DVE effects; it cannot do squeezebacks. MediaLive does have a keying layer, which enables moving graphics overlays onto the channel output. This would enable you to put up an LBAR animated graphic, but it would cover a region of the video. If you want a true video squeezeback, this would need to be done upstream of MediaLive.
More information on the motion graphics overlay keying can be found at:

I am using the upload image widget without success.
1) result.info.path returns invalid url.
2) There is no preview of the uploaded images due to no.1
3) No images are were uploaded to my media folder at Cloudinary.
Fiddle:

These are my preset settings:
Can someone share a working version of this widget + preset settings?
On successful upload, you need to check result.info.secure_url for a link to the asset. Currently, in your preset, you're using Async which means the incoming transformation is performed in the background (asynchronously), and as such, you will get a pending result. Async assumes you're using a Notification URL as a webhook where you'll receive the Upload API response when the processing is complete. In your case, I'd recommend turning the Async off.
Also, your incoming transformation configured in the preset is not valid and because of that, you will be getting an error on upload. Please console.log this in your JSFiddle to see it. Essentially, it'll be -
Auto gravity can only be used with crop, fill, lfill, fill_pad or
thumb
'auto' gravity (g_auto) implies cropping (automatically selecting the most interesting part of the image to focus on) and therefore you need to use an appropriate crop mode. 'scale' keeps all image data and no cropping is made so that is why g_auto can't work with it. Please see the following section of the documentation for details on the different crop modes - https://cloudinary.com/documentation/image_transformation_reference#crop_parameter - which will help you decide which one you want to use.
Lastly, you should also consider updating your incoming transformation so that it only resizes once, since currently, resizing it three times with the same crop mode is redundant. For example, you can use c_scale,q_auto,w_687 only, or if you want with 'auto' gravity you can try c_fill,g_auto,q_auto,w_687.
There is any possibility to upload a file with different sizes in DropzoneJs?
I'm using vue-dropzone which is made with dropzonejs and i have to upload the same file with different sizing for srcset.
Example:
I want to upload the file test.png which is 1000x500 px. There is any possibility to upload it at the same time in original resolution and also in 500x250px?
Image resizing in the browser has been a seat-of-the pants experience for a long time. Web assemblies are the way of the future for processing-intensive tasks in web apps. I came across this project the other day. It looks fantastic and I really can't wait to strip out our home-baked image resizing with canvas and replace it with this.
The usual reason for doing this is to avoid large uploads. It's a little bit weird to want to resize in the browser then upload the original. You might be better resizing on the server. You'll save bandwidth and the server libraries will be more mature than what's available on the client.
Along with the original image object you can add one more your custom resized image to the array of images by using resize config of dropzone. You can do the above on drop event or adddedFile event of dropzone.
I am currently testing a DSC-HX400. While I am able to do almost everything I need to with the camera there are a couple of items that are not exposed via the API that have frustrated my efforts.
1) The camera does not seem to offer an option, via the API or the camera itself, to capture images in RAW format. It does offer standard & fine JPEG format but both of those are leaving artifacts in the image that become extremely noticeable when you zoom in with an image editor. Is there a way to get the camera to capture RAW images? I do not need the SDK to return the data just to save it out to the card. If getting the RAW data is impossible has anyone found an inventive way to clean up the artifacts?
2) The camera supports both still shoot and movie mode but the API will only expose the mode that I am currently in. It makes it impossible to transition between still to movie mode (to allow recording) from the API but I can do that same transition by pressing a single button on the camera. Once I am recording a movie the API will allow me to transition back to still mode (by cancelling recording). Is there plans to support the ability to trigger a movie recording via the API if you are in a still capture mode (Seeing the firmware already supports this functionality)?
Answers to the questions below:
If the camera cannot capture RAW images, the API will not be able to either. I do not know of a way to capture RAW images but can only comment with regards to the API as I am not an expert on usage of the camera itself.
You can change between still and movie mode by using the "setShootMode" API.
I’m using the BuddyPress Activity Plus plugin and wanted to know if there was a way to call the full size image that was uploaded when viewing the single page of the activity?
I’ve looked at placing a line of code in “activity/entry.php” of the child theme but can’t find anything that will call its full size image, only the thumbnail shows with the link to the full size image to open in a lightbox.
This isn’t what I’m looking for, the full size image needs to be in place of the thumbnail when viewing the single activity page.
Any idea anyone? Sorry if this is the right place for this, just having trouble getting an answer
Many thanks
I'm looking to do a similar thing, not too much luck yet. Also - have you noticed that if you upload multiple images, they stack, rather then laying out side by side?
EDIT:
Found out how to make the images in the stream bigger:
You can set your preferred thumbnail size separately from your default thumbnail size settings, if you wish to do so. You can do that by adding this line to your wp-config.php:
define('BPFB_THUMBNAIL_IMAGE_SIZE', '200x200');
Where "200x200" are width and height (in that order), in pixels.
Finally, be sure to verify your default sizes for embedded media. It's in Settings -> Media -> Embeds -> Maximum embed size
