I agree with @Hans Kesting using Razor syntax would be best. Especially helpful would be to move away from DataSets and DataTabes and use models for your data. This would make iterating through your data and populating a table much easier with something like WebGrid. However, if none of this is possible what I have done in the past is:

create the HTML table string in a Helper method
pass the HTML string to a Controller action method
store the HTML string into the TempData object
access the TempData object and render the table to the view using:
@Html.Raw(TempData["html"])

Getting No audio tracks in MediaStream issue in firefox

Asked 2021-Jun-08 at 10:59

I am capturing user screen and audio using getDisplayMedia and getUserMedia and able to record the complete screen capture. But this works only on Chrome and not on Firefox. When I run my application on Firefox it throws error 'DOMException: AudioContext.createMediaStreamSource: No audio tracks in MediaStream'. Below is my code snippet. I have latest version of both browsers installed. Any help would be appreciated. Thanks in advance.

Answered 2021-Jun-08 at 10:59

Firefox doesn't currently support capturing audio using getDisplayMedia. There's a feature request for it.

What you could do is check whether your streams have any audio tracks before creating the audio node, like this:

It turns out video/mp4 works with iOS. It can be used for audio-only as well, even though it says video.

Since other browsers don't support video/mp4, a try/catch with the video/mp4 as a fallback can be used, which results in the following solution:

I guess you are trying to use firebase as a signalling medium and want to use react-native-webrtc for the video calling.

Answered 2021-Jun-02 at 04:47

Your structure is well done, though the if(user && speaking) can be fixed easily. You are calling the variable "user" at the beginning of the 'speaking' function, although you have already stated the variable user in the past let user = message.mentions.users.first();, to achieve the outcome you expect you should start by removing the "user" variable from this line connection.on('speaking', (user, speaking) => { and replace if(user && speaking) { with if(user === speaking). The difference is that now you would be saying "If the user mentioned is speaking", then you would be able to trigger an outcome.

I hope this was helpful!

Webm vs Opus - Quality? - youtube-dl context

Asked 2021-Jun-01 at 22:33

When I download audio from youtube via youtube-dl:

A) if I type -f bestaudio I get webm files which can't contain musical metadata and can't be played by most apps.

B) if I type -f bestaudio --extract-audio --add-metadata I get opus files which contain musical metadata and can be play by most apps.

I conclude Opus is more useful. However webm and opus files often appear to be slightly different on Spek and so I get doubtful since I don't know how to read such subtle difference.

Questions

Is someone able to explain me in casual language what is occurring in the process within youtube-dl when doing it with option A and when doing it with option B?
Which one is finer? Quality as when played online full on is a must, not simply to have fun listening to.
Is there any other info that could help me assure to download best unprocessed audio with youtube-dl?

I wish someone is able to help me, I thank you very much in advance! :)

webm is a media container similar to mkv, opus is a audio format which can be included in the webm among with video, other audio tracks and subtitles etc..

opus seems to have higher bitrate (better quality) than offered by youtube-dl/newpipe but not so great hardware support, that does not matter for your pc and phone though.

youtube does not offer uncompressed audio/video

In your stop function, you stop all the tracks on this.stream. That includes the video tracks from the desktop stream, but only the audio tracks from the merged audio stream. The original, individual audio tracks from the desktop and the mic are not stopped, so as far as the browser knows they are still active.

Here is one way to stop the original streams:

QUESTION

is it possible to assign multiple column/values using SET with data.table in R?

Asked 2021-May-31 at 10:57

Is it possible to assign values to multiple columns using "set?"

Here is an example. For context, I want to create two new sets of columns-- one that imputes missing/NA values to 0, and another that indicates whether missing values were imputed. The first set of columns will duplicate an existing set but have 0 instead of NA and carry the suffix "_M0." The second set will be 0/100 and carry the suffix "_MISS."

I will use the iris data frame as a starting point.
