QUESTION
Using my answer to my question on how to download files from a public Google drive I managed in the past to download images using their IDs from a python script and Google API v3 from a public drive using the following bock of code:
...ANSWER
Answered 2022-Mar-04 at 12:57Well thanks to the security update released by Google few months before. This makes the link sharing stricter and you need resource key as well to access the file in-addition to the fileId.
As per the documentation , You need to provide the resource key as well for newer links, if you want to access it in the header X-Goog-Drive-Resource-Keys as fileId1/resourceKey1.
If you apply this change in your code, it will work as normal. Example edit below:
QUESTION
I am very new to using Flutter and have never properly used an API without help. I want to make my application free (without tons of ads) so I was hoping to create a Patreon to support it's upkeep. When looking for tutorial videos online or any examples of code to use for either Flutter or any other languages I know how to use, I came up empty handed. So I was posting this question here hoping that someone could help me link the Patreon API to Flutter. The documentation doesn't say it connects directly to Flutter, so you'll have to use another language to access the information (best bet is Javascript or Python on my opinion) and relay that too Flutter.
I (and possibly other people) would need a button created for OAuth login through Patreon (that works on both iOS and Android). When the user goes through the login, it needs to grab which tier they are supporting, their username, and when their subscription will renew (monthly or yearly?). This then needs to be translated to Text widgets (displaying the tier and/or username) and a "visible:" property for Visibility widgets (displaying certain content based on the user's monthly subscription and making the same content invisible or put behind a newly visible lock page when their subscription ends/expires).
Sorry I know this is a lot to anwser, but I'm not very experienced with APIs and Flutter. I will appreciate any anwser that helps because I really want to make my app without tons of advertisements and I'm hoping this question will help other Flutter developers with the same goal of supporting their development financial without tons of advertising effecting the user's experiences on the app.
Patreon API OAuth Documentation https://docs.patreon.com/#oauth
Flutter JS (I think this may help connect with the Patreon API, but I'm not sure?) https://pub.dev/packages/flutter_js
Examples of code and a step by step guide would be fantastic, but anything will help. Thank you again!

QUESTION
I am following Stanfords' CS193p Developing Apps for iOS online course.
It is using the Grand Central Dispatch (GCD) API for a demo of multithreading. But they noted, that
"GCD has been mostly replaced by Swift's new built-in async API as of WWDC 2021".
So I wanted to learn how the code from the Lecture would look like after updating it to use this new API.
After watching Apple's WWDC videos, it seems to me like
DispatchQueue.global(qos: .userInitiated).async { } is replaced in this new async API with Task { } or Task(priority: .userInitiated) {}, but I'm not sure, what has DispatchQueue.main.async { } been replaced with?
So, my questions are:
- Am I correctly assuming, that
DispatchQueue.global(qos: .userInitiated).async { }has been replaced withTask(priority: .userInitiated) {} - What has
DispatchQueue.main.async { }been replaced with?
Please help, I want to learn this new async-await API.
Here's the code from the Lecture, using old GCD API:
...ANSWER
Answered 2022-Feb-24 at 15:54If you really are going to do something slow and synchronous, Task.detached is a closer analog to GCD’s dispatching to a global queue. If you just use Task(priority: ...) { ... } you are leaving it to the discretion of the concurrency system to decide which thread to run it on. (And just because you specify a lower priority does not guarantee that it might not run on the main thread.)
For example:
QUESTION
I would like to be able to robustly stop a video when the video arrives on some specified frames in order to do oral presentations based on videos made with Blender, Manim...
I'm aware of this question, but the problem is that the video does not stops exactly at the good frame. Sometimes it continues forward for one frame and when I force it to come back to the initial frame we see the video going backward, which is weird. Even worse, if the next frame is completely different (different background...) this will be very visible.
To illustrate my issues, I created a demo project here (just click "next" and see that when the video stops, sometimes it goes backward). The full code is here.
The important part of the code I'm using is:
...ANSWER
Answered 2022-Jan-21 at 19:18The video has frame rate of 25fps, and not 24fps:
After putting the correct value it works ok: demo
The VideoFrame api heavily relies on FPS provided by you. You can find FPS of your videos offline and send as metadata along with stop frames from server.
The site videoplayer.handmadeproductions.de uses window.requestAnimationFrame() to get the callback.
There is a new better alternative to requestAnimationFrame. The requestVideoFrameCallback(), allows us to do per-video-frame operations on video.
The same functionality, you domed in OP, can be achieved like this:

QUESTION
How to memory-map a PCI Base Address Register (BAR) from a PCIDriverKit driver (DEXT) to a userspace application?
Memory-mapping from a driver extension to an application can be accomplished by implementing the IOUserClient::CopyClientMemoryForType in the user client subclass (on the driver side) and then calling IOConnectMapMemory64 (from the user-space application side). This has been very nicely and thoroughly explained in this related answer.
The only missing bit is getting an IOMemoryDescriptor corresponding to the desired PCI BAR in order to return it from the CopyClientMemoryForType implementation.
Asked another way, given the following simplified code, what would be the implementation of imaginaryFunctionWhichReturnsTheBARBuffer?
ANSWER
Answered 2022-Jan-16 at 17:01Turns out IOPCIDevice::_CopyDeviceMemoryWithIndex was indeed the function needed to implement this (but the fact that it's private is still an inconvenient).
Bellow is some sample code showing how this could be implemented (the code uses MyDriver for the driver class name and MyDriverUserClient for the user client).
Relevant sections from MyDriver.cpp implementation:
QUESTION
I am trying to use the video_player, but I am getting the below error. I have also added an MRE (minimum reproducible example).
I have used an emulated Pixel 4, an emulated Pixel 4 XL, and an emulator Pixel 5 with the Android Studio Beta, but none of them worked.
The below error was when I was using a Pixel 4 XL, but the error was the same with all of them.
Error:
...ANSWER
Answered 2022-Jan-11 at 08:53It can be a bug of that Flutter package, indeed. Have you tried to create an issue in GitHub of that package?
Secondly, during my development, I see several times when emulators just fail and real devices always work. The solution I used is - simply to do not test them on simulators. Real users never use simulators, aren't they?
It can be a bug of the library when running on x86 arch (the arch simulators use). Then, nobody with a real device (arm arch) will ever see the bug.
Thirdly, what about trying to use "cloud real devices" to test whether they work on real Pixel devices that you are worried about. There are many platforms that host some real devices and you can connect to them via a webpage and test your app.

QUESTION
I wrote a python script that generates a xstack complex filter command. The video inputs is a mixture of several formats described here:
I have 2 commands generated, one for the xstack filter, and one for the audio mixing.
Here is the stack command: (sorry the text doesn't wrap!)
...ANSWER
Answered 2021-Dec-16 at 21:11I'm a bit confused as how FFMPEG handles diverse framerates
It doesn't, which would cause a misalignment in your case. The vast majority of filters (any which deal with multiple sources and make use of frames, essentially), including the Concatenate filter require that be the sources have the same framerate.
For the concat filter to work, the inputs have to be of the same frame dimensions (e.g., 1920⨉1080 pixels) and should have the same framerate.
(emphasis added)
The documentation also adds:
Therefore, you may at least have to add a scale or scale2ref filter before concatenating videos. A handful of other attributes have to match as well, like the stream aspect ratio. Refer to the documentation of the filter for more info.
You should convert your sources to the same framerate first.
QUESTION
In the example below, I'm trying to capture all the videos in this script. However, I'm only able to capture the first video. I understand this has to do with getElementById and not querySelectorAll, but I'm not sure how to implement it in this script.
ANSWER
Answered 2021-Dec-11 at 14:57You were only selecting the first .wistia block with this line:
const clickToPlay = document.querySelectorAll('.wistia')[0];
The other issue is the duplicated id as you noted, so that only the first video would be properly loaded. I have removed the id attribute entirely from the HTML, and updated the JS to properly loop over each .wistia div, attach a click handler, and then read the video ID from the associated child node.

Install videos
You can use videos like any standard Python library. You will need to make sure that you have a development environment consisting of a Python distribution including header files, a compiler, pip, and git installed. Make sure that your pip, setuptools, and wheel are up to date. When using pip it is generally recommended to install packages in a virtual environment to avoid changes to the system.
