I have installed wiziq plugin for web conference via canvas lms made in ruby on rail. When I join the conference I get the error as given below Uninitialize constant Wiziq::Auth base::HMAC
I am not understand where is the problem. Can any body help me to resolve it?
WizIq support in Canvas LMS was dropped last November. See link here:

You can probably bring back wiziq by copying vendor/plugins/wiziq from this release: https://github.com/instructure/canvas-lms/tree/06dfa7fb6ddeb0fc63a31c723586e620ebbfbe5d/vendor/plugins to your release you are currenty at. I haven't tried this myself so take it with a grain of salt

I can find a release in Azure DevOps Api 5.1 by a request to https://vsrm.dev.azure.com/mycompany/myproject/_apis/release/releases/myreleaseid?api-version=5.1
How can I get the workitems of that release as shown on the devops portal under Deployment - Stages - Workitems?
My naive approach just using https://vsrm.dev.azure.com/mycompany/myproject/_apis/release/releases/myreleaseid/workitems?api-version=5.1
resulted in a 404.
There is a stakeholder in the workitem and I want to send him a notification adter the release.
How can I get the workitems of that release as shown on the devops
portal under Deployment - Stages - Workitems?
Hard to say, but I don't find any document about this topic... So I determine to use F12 to find that. And here's the one I finally find:
Get:https://vsrm.dev.azure.com/mycompany/myproject/_apis/Release/releases/myreleaseId/workitems?baseReleaseId={my baseReleaseId}&%24top=250&artifactAlias={my artifactAlias}
It will returns the IDs of the workItems for the release. Its response format:
After you get the IDs, it's easy to get details if you need using Get Work Items Batch or what.
In addition:
1.myreleaseId is the ReleaseID. (On my side, the ID is 7 if it's Release-7)
2.my artifactAlias is this:
3.For my baseReleaseId, I'm not 100% sure about its meaning. I think it could be something like ReleaseToCompareAgainst. Hint from Daniel. (On my side, if my releaseId=7, then I use basereleaseID=6(7-1), it works to get the correct WIT ids). (Actually I suggest you can use F12 in that web page to check your corresponding URL.)
And according to Mathias F: The baseReleaseId realy is the last previous release that has a deployment (-1 in some cases)
4.About how to use F12 to find rest api which may not be documented:
Hope all above helps :)
I'm using the Chrome Web Serial API. So far it's working fine, but now and I'm trying to get the (already opened) port metadata (port name, device ID, etc.) and I'm a bit lost.
Here are the steps to follow:
https://wicg.github.io/serial/#getting-serial-port-metadata
but so far I cannot get the information.
If I try by navigating the port class, the DevTools console trows "ƒ () { [native code] }".
I cannot find a suitable example of how to implement this.
Does anyone have a hint?
Thanks in advance!!
Daniel.
It seems like it hasn't been implemented in Chromium yet. Keep in mind that the specs are sort of guides for vendors to follow when implementing a feature, but the actual shipped implementation can differ.
If you check the Web Serial API's code in the Chromium repo for Chrome 80 (current version at the time of writing) and 84.0.4112.1 you'll see that they only include the following methods:
open
readable
writable
getSignals
setSignals
close
You can read the latest comments on this API here: https://bugs.chromium.org/p/chromium/issues/detail?id=884928
I am trying to using the CameraCaptureSequence API to capture a sequence of frames of a scene. Currently, I am trying to modify the code available on MSDN for the basic lens sample to accomplish this.
here is what I have done to capture 3 frames. But the app crashes upon start:
public async Task PrepareCameraCaptureSequence()
{
this.cameraCaptureSequence = this.PhotoCaptureDevice.CreateCaptureSequence(3);
this.cameraCaptureSequence.FrameAcquired += cameraCaptureSequence_FrameAcquired;
await this.PhotoCaptureDevice.PrepareCaptureSequenceAsync(this.cameraCaptureSequence);
}
Most of the online resources I saw do the above for just one frame, i.e., using "this.PhotoCaptureDevice.CreateCaptureSequence(1)". Can someone please help me out with capturing multiple frames using CameraCaptureSequence?
Thanks
Ekta
So, I have found something on this MSDN article.
Apparently, the Windows.Phone.Media.Capture.CameraCaptureSequence class currently supports only single frame capture. Hence, while working with the current release of Windows 8 APIs, you must specify a single frame when you call the CreateCaptureSequence method.
That's too bad, I am guessing I will have to work with the frames of a video stream. If anyone comes across another answer to this question, please do share!
I've installed Samsung Smart TV SDK and I'm trying to get the current frame/time the video is playing.
The video is already running, and everything seems to work just fine, but when I try to get the current time, using $('#video1')[0].currentTime, I'm just getting the value in seconds, without the milliseconds.
I'm developing a program where I need the milliseconds, but it seems impossible to get them using the SDK. What am I doing wrong? Any tips? Or it's a SDK limitation, and I'll never be able to get the current "REAL" time?
I found some solutions online, read a lot about the video tag in HTML 5, but the SDK documentation seem to lack a lot of information, and some are even wrong...
I followed this example: http://jsfiddle[dot]net/893aM/1/
Works just fine in any browser, but when I apply it to the Smart Tv, I just get the time in seconds, no luck with my precious milliseconds...
Thank you.
Please take a look at the following links:
Using SEF Plugin and SEF Plugin API
SEF Plugin Player
"OnCurrentPlaybackTime" event from the SEF Plugin Player.
EDIT:
Player.OnCurrentPlayTime = function (milliseconds) {
// use 'milliseconds' parameter
}
or you can convert it by yourself
Player.OnCurrentPlayTime = function (time) {
var hms = time.toString().split(":");
var seconds=(parseInt(hms[0],10)*60*60+parseInt(hms[1],10)*60+parseInt(hms[2],10))*1000;
alert(seconds);}
I'm trying to capture audio using WASAPI. My code is largely based on the ChatterBox VoIP sample app. I'm getting audio buffers, but they are all silent (flagged AUDCLNT_BUFFERFLAGS_SILENT).
I'm using Visual Studio Express 2012 for Windows Phone. Running on the emulator.
I had the exact same problem and managed to reproduce it in the ChatterBox sample app if I set Visual Studio to native debugging and at any point stepped through the code.
Also, closing the App without going through the "Stop" procedure and stopping the AudioClient will require you to restart the emulator/device before being able to capture audio data again.
It nearly drove me nuts before I figured out the before mentioned problems but I finally got it working.
So..
1. Be sure to NOT do native debugging
2. Always call IAudioClient->Stop(); before terminating the App.
3. Make sure you pass the correct parameters to IAudioClient->Initialize();
I've included a piece of code that works 100% of the time for me. I've left out error checking for clarity..
LPCWSTR pwstrDefaultCaptureDeviceId =
GetDefaultAudioCaptureId(AudioDeviceRole::Communications);
HRESULT hr = ActivateAudioInterface(pwstrDefaultCaptureDeviceId,
__uuidof(IAudioClient2), (void**)&m_pAudioClient);
hr = m_pAudioClient->GetMixFormat(&m_pwfx);
m_frameSizeInBytes = (m_pwfx->wBitsPerSample / 8) * m_pwfx->nChannels;
hr = m_pAudioClient->Initialize(AUDCLNT_SHAREMODE_SHARED,
AUDCLNT_STREAMFLAGS_NOPERSIST | AUDCLNT_STREAMFLAGS_EVENTCALLBACK,
latency * 10000, 0, m_pwfx, NULL);
hr = m_pAudioClient->SetEventHandle(m_hCaptureEvent);
hr = m_pAudioClient->GetService(__uuidof(IAudioCaptureClient),
(void**)&m_pCaptureClient);
And that's it.. Before calling this code I've started a worker thread that will listen to m_hCaptureEvent and call IAudioCaptureClient->GetBuffer(); whenever the capture event is triggered.
Of course using Microsoft.XNA.Audio.Microphone works fine to, but it's not always an option to reference the XNA framework.. :)
It was a really annoying problem which waste about 2 complete days of mine.My problem was solved by setting AudioClientProperties.eCatagory to AudioCategory_Communications instead of AudioCategory_Other.
After this long try and error period I am not sure that the problem won't repeat in the future because the API doesn't act very stable and every run may return a different result.
Edit:Yeah my guess was true.Restarting the wp emulator makes the buffer silent again.But changing the AudioClientProperties.eCatagory back to AudioCategory_Other again solve it.I still don't know what is wrong with it and what is the final solution.
Again I encounter the same problem and this time commenting (removing) the
properties.eCategory = AudioCategory_Communications;
solve the problem.
I can add my piece of advice for Windows Phone 8.1.
I made the following experiment.
Open capture device. Buffers are not silent.
Open render device with AudioDeviceRole::Communications. Buffers immediately go silent.
Close render device. Buffers are not silent.
Then I opened capture device with AudioDeviceRole::Communications and capture device works fine all the time.
For Windows 10 capture device works all the time, no matter if you open it with AudioDeviceRole::Communications or not.
I've had the same problem. It seems like you can either use only AudioCategory_Other or create an instance of VoipPhoneCall and use only AudioCategory_Communications.
So the solution in my case was to use AudioCategory_Communications and create an outgoing VoipPhoneCall. You should implement the background agents as in Chatterbox VoIP sample app for the VoipCallCoordinator to work .
