I need to create a blow functionality. I am using AVAudioRecorder for this. The problem is that my app along with the detection of blow also detects voice. What I want is to just detect the blow.
Please guide me.
I am using code from the given link

Currently there is a flutter app and it needs to be protect from screenshot or recording
but when I search about this, there is no way to implement this in a official way
but it seems there are some tricks (like 60fps? I know the concept but I don`t know how to implement this)
you can see the black screen when record the video on Netflix also (they prevent in some ways)
how could I achieve this? thanks
there is a package called window manager which does just the thing that you are asking it restricts external apps from recording as well as does not allow screenshots to be taken
a detailed tutorial is given in this article.
What is the standard way of saving videos using MeshcatVisualizer? I know the following works for wrappers of PyPlotVisualizer:
visualizer.start_recording()
simulator.AdvanceTo(T)
ani = visualizer.get_recording_as_animation()
But the two relevant methods are not available for MeshcatVisualizer, and there don't seem to be any examples in the repo that create videos using it, and none of the methods that the class does have seemed like promising candidates. Failing that, is there another way of saving videos for 3D visualizations?
Meshcat has an animation tool: https://github.com/rdeits/meshcat-python/blob/master/animation_demo.ipynb , you can access MeshcatVisualizer's meshcat.Visualizer instance via MeshcatVisualizer.vis. However, MeshcatVisualizer doesn't have a function like MeshcatVisualizer.convert_to_video that supports this animation tool at the moment. Perhaps the easier route for now is screen recording.
I don't believe that meshcat offers it's own recording functionality, which means the recommended workflow would be to just use your favorite screen recorder software. I've forwarded this to a few meshcat experts in case they have something better to recommend.
Update: In addition to rdeits answer above, he had a few more details in email:
there's a built in animation API with recording support in
meshcat-python (see "Recording an Animation" in
https://github.com/rdeits/meshcat-python/blob/master/animation_demo.ipynb
), but AFAICT Drake's MeshcatVisualizer isn't hooked up to it. It
might not be that hard to do so--the basic idea is that you can use
at_frame to get a representation of a single frame of an animation
that behaves like a meshcat.Visualizer. You can call set_transform
on that frame, and rather than moving anything in the viewer it will
instead record that action into an animation track. Then you can send
the whole animation at once to the visualizer and let the browser side
handle replaying and recording it.
I have planned to detect an image in a news paper play the video relevant to it. I have seen several news paper reading AR apps include this feature. But i couldn't find how to do so. How can I do it??
I dont expect any code. But like to know what are the steps I should follow to do this. Thank you.
You need to browse through the available marker-based AR SDKs - such SDKs let you defined in advance the database of images you would like to detect and respond to, and once any of these images is detected during runtime, you get some kind of an event with data on the detected image.
Vuforia is considered a good one and it has good samples, so it is supposed to be easier to start with. You should also check out Kudan, and there are more.
I have started developing a Blackberry App in which it requires to implement sign pad. I googled about this and got a link related to this. From this I am not able to view code through Abode Flash Player nor able to get other resource to implement sign pad.
I don't think you'll find a reliable library for this. If you can't find any, your best bet would be to create your own by listening and drawing on a canvas.
Check out this solution. It's likely not 100% complete, but its a start.
As the title says, im simply wondering if it is possible to use the GPS tracking and POI part of junaio, and att the same time use the scan functionality to scan and recognize images. Im working with a group at a project which demands that we use both functionalities, and we are at the moment stuck on trying to send 2 XML documents, causing the server to return nothing at all. I simply want to know if it is possible to use both functionalities in the same channel, and I would greatly appriciate if someone would point me in a direction which could help me solve our problems, since I've been able to find absolutley nothing on my own. Thanks beforehand!
Scan + GPS/compass is not possible at the moment.
However, it's possible to use GPS/compass tracking and continuous visual search at the same time. This might be the closest thing to your requirements.
