QUESTION
I am taking the running of the code from someone from work, I am attempting to move specific cells within a excel spreadsheet to a Microsoft word document. Currently, three paragraphs are moved over, however, I want to introduce a 4th paragraph, with the *** representing code I have added in.
When I try running the code after adding the lines in, I get the error message "The requested member of the collection does not exist". Can anyone look over the code and see where I am going wrong?
Apologies, I have added the entire code block, so it is lengthy. Thanks

So if I've got text like:
...ANSWER
Answered 2022-Feb-04 at 08:07Text objects always go outwards so, even if you try something like i{
, which covers a smaller region than a{
, the selection will inevitably be extended.
As you mentioned, you can change the geometry of the selection with o
and various motions but that's cumbersome and the alternative, leaving visual mode, moving the cursor, and selecting again, is sadly just as cumbersome.
Building a custom "shrinking" pseudo text object might be possible, though, and something the community would probably gladly welcome.

The quick and dirty code below seems to work reasonably well for a{

QUESTION
For the simple vertex shader below to render a triangle, when is it safe to update the uniform mvpMatrix
from the CPU (using glUniformMatrix4fv
)? Is it safe to assume that after a draw call, e.g. glDrawArrays
that the uniform can be updated for the next draw? Or are there sync mechanisms to ensure that the update is not taking place mid way through the vertex shader applying the MVP
matrix.
ANSWER
Answered 2022-Jan-15 at 17:01OpenGL is defined as a synchronous API. This means that everything (largely) happens "as-if" every command is executed fully and completely by the time the function call returns. As such, you can change uniforms (or any other state) as you wish without affecting any prior rendering commands.
Now, that doesn't make it a good idea. But how bad of an idea it is depends on the kind of state in question. Changing uniform state is extremely cheap (especially compared to other state), and implementations of OpenGL kind of expect you to do so between rendering calls, so they're optimized for that circumstance. Changing the contents of storage (like the data stored in a buffer object used to provide uniform data), is going to be much more painful. So if you're using UBOs, its better to write your data to an unused piece of a buffer than to overwrite the part of a buffer being used by a prior rendering command.

QUESTION
Ok so this is what is going on I built this horror movie bucket list app as my final project for my bootcamp and the MVP went over well and I got my certification but since I have graduated I want to add a little more functionality to this app kind of the stuff that I did not get around to doing before the end of classes. With that being said I have created a list that will display movies that you mark as loved it on a different page I can get it to throw my to the right page and console log stuff that I put in so all of my methods and stuff are working as correctly as I think that I need them. But the big issue is that the box art that I have on my backend (ruby) will not render on the page I have stared at this for three days and my brain hurts using the syntax that I am using on all of the other pages works there but not on this page. Any help would be greatly appreciated.

QUESTION
I have a lot of long (45 mins - 90 mins) MP4 videos in a public S3 bucket and I want to play them in my iOS app using AVPlayer
.
I am using AVPlayerViewController
to play them but I need to wait several minutes before they start playing as it downloads the whole video rather than streaming it.
I am caching it locally so this is only happening the first time but I would love to stream the video so the user doesn't have to wait for the entire video to download.
Some people are pointing out that I need Cloudfront to stream videos but in the documentation, I've read that this is only necessary when you have many people streaming the same file. I'm building a MVP so I only need a simple solution.
Is there any way to stream an MP4 video from an S3 bucket with AVPlayerViewController
without it fully downloading the file before playing it to the user?
ANSWER
Answered 2022-Jan-12 at 12:17AVPlayer
does not support 'streaming' (HTTP range requests) as you would define it, so either use an alternative video player that does or use a real media streaming protocol like HLS which is supported by AVPlayer
& would start the video before downloading it all.
CloudFront is great for delivery in general but is not truly needed - you may have seen it mentioned due to CloudFront RTMP distributions but they now have been discontinued.
Detailed AnswerS3 supports a concept called byte-range fetches using HTTP range requests - you can verify this by doing a HEAD request to your video file & seeing that the Accept-Ranges
header exists with a value set to bytes (or not 'none').
Load your MP4 file in the browser & notice that it can start as soon as you click play. You're also able to move to the end of the video file and yet, you haven't really downloaded the entire video file. HTTP range requests are what allow this mechanism to work. Small chunks of the video can be downloaded as & when the user gets to that part of the video. This saves the file server & the user bandwidth while providing a much better user experience than the client downloading the entire file.
The server would need to support byte-range fetches in the first instance before the client can then decide to make range requests (or not to). The key is that, once the server supports it, it is up to the HTTP client to decide whether it wants to fetch the data in chunks or all in one go.
This isn't really 'streaming' as you know it & are referring to in your question but it is more 'downloading the video from the server in chunks and playing it back' using HTTP 206 Partial Content responses.
You can see this in the Network tab of your browser as a series of multiple 206 responses when seeking in the video. The entire video is not downloaded but the video is streamed from whichever position that you skip to.
The problem withAVPlayer
Unfortunately, AVPlayer
does not support 'streaming' using HTTP range requests & HTTP 206 Partial Content responses. I've verified this manually by creating a demo iOS app in Xcode.
This has nothing to do with S3 - if you stored these files on any other cloud provider or file server, you'd see that the file is still fully loaded before playing.
The possible solutionsNow that the problem is clear, there are 2 solutions.
Using an alternative video playerThe easiest solution is to use an alternative video player which does support byte-range fetches. I'm not an expert in iOS development so I sadly can't help in recommending an alternative but I'm sure there'll be a popular library that the industry prefers over the in-built AVPlayer
. This would provide you with your (extremely common) definition of 'streaming'.
However, if you must use AVPlayer
, the solution is to implement true media streaming with a video streaming protocol - true streaming also allows you to leverage features like adaptive bitrate switching, live audio switching, licensing etc.
There are quite a few of these protocols available like DASH (Dynamic Adaptive Streaming over HTTP), SRT (Secure Reliable Transport) & last but not least, HLS (HTTP Live Streaming).
Today, the most widely used streaming protocol on the internet is HLS, created by Apple themselves (hey, maybe the reason to not support range requests is to force you to use the protocol). Apple's own documentation is really wonderful for delving deeper if you are interested.
Without getting too much into protocol detail, HLS will allow playback to start more quickly in general, fast-forwarding can be much quicker & delivers video as it is being watched for the true streaming experience.
To go ahead with HLS:
Use AWS Elemental MediaConvert to convert your MP4 file to HLS format - the resulting output will be 1 (or more)
.M3U8
manifest files in addition to.ts
media segment file(s)Upload the resulting output to S3

QUESTION
In the attempt to get diffuse lighting correct, I read several articles and tried to apply them as close as possible.
However, even if the transform of normal vectors seems close to be right, the lighting still slides slightly over the object (which should not be the case for a fixed light).
Note 1: I added bands based on the dot product to make the problem more apparent.
Note 2: This is not Sauron eye.
In the image two problems are apparent:
- The normal is affected by the projection matrix: when the viewport is horizontal, the normals display an elliptic shading (as in the image). When the viewport is vertical (height>width), the ellipse is vertical.
- The shading move over the surface when the camera is rotated around the object.This is not much visible with normal lighting, but get apparent when projecting patterns from the light source.
Code and attempts:
Unfortunately, a minimal working example get soon very large, so I will only post relevant code. If this is not enough, as me and I will try to publish somewhere the code.
In the drawing function, I have the following matrix creation:
...ANSWER
Answered 2021-Dec-24 at 14:40Lighting calculations should not be performed in clip space (including the projection matrix). Leave the projection away from all variables, including light positions etc., and you should be good.
Why is that? Well, lighting is a physical phenomenon that essentially depends on angles and distances. Therefore, to calculate it, you should choose a space that preserves these things. World space or camera space are two examples of angle and distance-preserving spaces (compared to the physical space). You may of course define them differently, but in most cases they are. Clip space preserves neither of the two, hence the angles and distances you calculate in this space are not the physical ones you need to determine physical lighting.
