I am writing a program to real time convert between AMR-nb and ILBC. As I would like to convert it in real time, I don't want any files to be generated. calling shell by STDIN/STDOUT/piping or call program library (JAVA/node.js) directly are preferred.
I found that ffmpeg/sox do not support both formats. What ways do you think I can use to convert between them?

Is there a way to directly get script representation of a Cairo drawing without saving the script to a file in C++?
I'm trying to get the script in order to do test by comparing scripts. Have tried cairo_script_create_for_stream but using streaming seems a little bit overkill for my use case.
Building a REST python client for a server that expects timestamps to be passed in this format:
2018-05-17T06:57:16.300Z
When writing clients for this server, it is easy to get this kind of timestamp in both Java (serializing an Instant with Jackson) and Javascript (using new Date().toISOString()).
However, I couldn't find a standard way of getting this sort of timestamp in Python using the standard library or the common packages for handling time (Arrow, Pendulum).
All the solutions I found online required manually defining the string format, or (even worse) doing string manipulations to add the Z at the end of the timestamp and put the T in place.
So - is there a standard way of getting current UTC time with the Z notation in Python?
Found an answer. Using Pendulum, one can do the following:
pendulum.now(pendulum.UTC).to_iso8601_string()
I want to create a simulation in Xcos (part of Scilab) representing the real Arduino Uno system. That means changing its input values during the simulation based on output. The problem is that I need to find the way how to handle strings as input and output. How is this possible?
The solution that comes to my mind is to somehow use Atoms Serial Communication Toolbox functions like writeserial() and readserial() in my Xcos scheme. But I do not have any idea if this is even possible. Any idea?
I managed to use those functions in my Xcos scheme by putting them into Scilab function block (scifunc_block_m) and then parsing them to get the correct output. And it seems that for handling strings in Xcos for input/output it is possible to convert string to ascii() and work with that.
Is there a way to pass Matlab data to another Matlab thread? I'm importing data from C++ to Matlab and want to pass this data to another function, which loops permanently. C++ opens a new Matlab window, so variables can not be shared easily. One way would be to write the imported data to a file and read this file in the other loop, but this takes quite some time. Is there someone with a better solution?
The standard solution costs money: Parallel Computing Toolbox.
I'm trying to create a program that moves a little man forward by walking or running etc.
I need to be able to save the state of the little man and load it at any given time and I have no idea how to do this. Could anyone please help me get the ball rolling?
You will probably have the state (the position of the character, maybe something else) stored in some sort of Python data structures. You could create a file storing this information. The most obvious ways are:
Create a plain-text file with text/numbers needed to recreate the state. You will need to parse it to load the state, but you can choose any file format you like.
Use pickle to dump your Python objects to a file directly. You will then read them using pickle.load and won't have to bother parsing the file.
