I converted an avi file to a mp4 file with the following command, but the converted mp4 file produced no audio when played with QuickTime (no such problem with other players). I was able to convert mkv to mp4 with the same command without the audio problem....
ANSWERAnswered 2022-Feb-06 at 19:04
From your log I can see that your input audio is MP3.
In previous versions of the spsurvey package, it was possible to draw random points within polygons in a shapefile using a somewhat complicated
design specification. (See here for an example).
The newly updated version of
spsurvey (5.0.1) appears very user-friendly, except I cannot figure out how to perform a GRTS draw of more than one point within polygons. Below is an example:
Suppose I want to draw 10 random points using GRTS within the states of Montana and Wyoming. The
grts() call requires an sf object, so we can get an sf object first.

I'm developing a plugin application for AutoCAD 2021 using the ObjectARX C#.Net framework. I'm trying to refactor it / make the code easier to understand at the moment, as I'll be returning to school soon and I'm currently the only full-time coder at my place of work.
I'm considering replacing a chunk of my code with a helper function so it can be reused in future AutoCAD projects, however it relies on IDisposable "transaction" objects to function at the moment.
If I call a function from within a transaction "using" statement, will it automatically make use of the transaction itself? Or, do I need to pass the transaction object to the function?
Edit: Including some sample code here....
ANSWERAnswered 2021-Aug-12 at 15:15
For most things, the answer would be "no":
using only impacts the lifetime of the object you're dealing with.
However, Transactions are kind of a special case. Creating and disposing a transaction causes certain state information to be associated with the current execution context, and many libraries have been written to detect and respect that state. So if your code calls into a method which then goes and performs database access, it's likely that the database access will be performed within the scope of that transaction.
You can find more details about how that works here. Things like how the static
Transaction.Current property gets set when you create a new transaction scope, how the transaction manager determines which transaction actions participate in, and how if necessary you can suppress the current transaction scope if you have code that needs to execute outside of whatever transaction is currently active.
I am trying to add
xfade filter and the command is working but audio of second video is missing in output video.
command is -...
ANSWERAnswered 2021-May-27 at 21:54
You didn't tell ffmpeg what to do with the audio so it just picked the audio from the first input (see stream selection).
Because you are using xfade you probably want to use acrossfade as shown in Merging multiple video files with ffmpeg and xfade filter:
one of our project is to create this basic website that has a homepage, Login-page, admin-page.
I have made the basic outline, I just cant properly fix the positionings of the divs. All pages must have a header and footer and should be consistent to all pages.
On my admin-page,
I have the header properly positioned. the content is 6 pictures in 3x2 grid which I have done using float lefs to arrange them. but my footer cant position itself at the verybottom of the page even tho it has the
bottom: 0px; I cant seem to make it work.
how do I fix this?
PS. This is my first time asking in this website, I dont know how to show my code so you all can see what I did....

Pretty much brand new to ML here. I'm trying to create a hand-detection CoreML model using turicreate.
The dataset I'm using is from https://github.com/aurooj/Hand-Segmentation-in-the-Wild , which provides images of hands from an egocentric perspective, along with masks for the images. I'm following the steps in turicreate's "Data Preparation" (https://github.com/apple/turicreate/blob/master/userguide/object_detection/data-preparation.md) step-by-step to create the SFrame. Checking the contents of the variables throughout this process, there doesn't appear to be anything wrong.
Following data preparation, I follow the steps in the "Introductory Example" section of https://github.com/apple/turicreate/tree/master/userguide/object_detection
I get the hint of an error when turicreate is performing iterations to create the model. There doesn't appear to be any Loss at all, which doesn't seem right.
After the model is created, I try to test it with a test_data portion of the SFrame. The results of these predictions are just empty arrays though, which is obviously not right.
After exporting the model as a CoreML .mlmodel and trying it out in an app, it is unable to recognize anything (not surprisingly).
Me being completely new to model creation, I can't figure out what might be wrong. The dataset seems quite accurate to me. The only changes I made to the dataset were that some of the masks didn't have explicit file extensions (they are PNGs), so I added the .png extension. I also renamed the images to follow turicreate's tutorial formats (i.e.
vid4frame025.mask.0.png. Again, the SFrame creation process using this data seems correct at each step. I was able to follow the process with turicreate's tutorial dataset (bikes and cars) successfully. Any ideas on what might be going wrong?
ANSWERAnswered 2020-Mar-06 at 20:49
I found the problem, and it basically stemmed from my unfamiliarity with Python.
In one part of the Data Preparation section, after creating bounding boxes out of the mask images, each annotation is assigned a
'label' indicating the type of object the annotation is meant to be. My data had a different name format than the tutorial's data, so rather than each annotation having
'label': 'bike', my annotations had
'label': 'vid4frame25`, 'label': 'vid4frame26', etc.
Correcting this such that each annotation has
'label': 'hand' seems to have corrected this (or at least it's creating a legitimate-seeming model so far).
I've been trying to run the following piece of Scala code:...
ANSWERAnswered 2020-Jan-28 at 19:02
You need to use the place it's actually defined in,
javax.swing.WindowConstants. When the Java compiler sees
JFrame.EXIT_ON_CLOSE it's rewritten into
WindowConstants.EXIT_ON_CLOSE; the Scala compiler doesn't do that (neither does Kotlin).
It used to be declared in
JFrame but was removed in Java 9; it's a source- and binary-compatible change for Java, as described in the link, but not source-compatible for Scala/Kotlin.
