Audio | Teensy Audio Library | Audio Utils library

I have done a small program, and it shows a weird behavior that I cannot explain. I am using rodio crate to try out some audio stuff.

I have done two programs that, in my opinion, should give the same result.

The first one I use matches to handle errors:

I have been trying out an open-sourced personal AI assistant script. The script works fine but I want to create an executable so that I can gift the executable to one of my friends. However, when I try to create the executable using the auto-py-to-exe, it states the below error:

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:

I am looking for a way to detect if the device I am using can support Dolby Atmos sounds.

After searching around I found this call.

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!)

I want to extract how many positive reviews by brand are in a dataset which includes reviews from thousands of products. I used this code and I got a table including percentaje of positive and non-positive reviews. How can I get only the percentage of positive reviews by brand? I only want the "True" results in positive_review. Thanks!

I am using pyaudio to record sounds on my Mac BigSur 11.6 (20G165). Specifically, I'm redirecting sound from an application to the input using BlackHole, which works fine.

It usually works fine but, sometimes, I get this error in the Terminal:

||PaMacCore (AUHAL)|| Error on line 2500: err='-10863', msg=Audio Unit: cannot do in current context

Any idea why or how I could prevent it from happening (like, waiting until PaMacCore is ready to record again or something)?

I already tried reinstalling but it doesn't help

This use case is a service that manually encodes a series of uncompressed .wav media segments into .m4s fragments for broadcast via MPEG-DASH, using ffmpeg to compress the .wav to .aac and sannies/mp4parser to assemble the aac audio into an .m4s media fragment.

I created this public GitHub project to reproduce the issue in its entirety.

For example, here's the custom CustomFragmentMp4Builder.java class.

It's critical that we be able to designate this single .m4s fragment with a sequence number (index) that we will manually increment for each media segment.

The objective is to build an .m4s fragment comprising the box types SegmentTypeBox, SegmentIndexBox, and MovieFragmentBox. As For reference, I have used mp4parser to inspect an .m4s fragment that was generated via ffmpeg -f hls. This specification is available here as a .yaml file

My implementation creates an MP4 without error. But, when the unit test attempts to read the file that the ChunkMp4Builder just wrote to a temp folder:

After looking to implement WebRTC with a Client to Server model (like Discord), I came to the conclusion that the way to do this is to have 2 clients - the server and client. Audio streams can be overlayed and sent back to the user in 1 single stream.
