Minimal example: transcode from MP3 to WMA:
ffmpeg -i input.mp3 output.wma
You can get the list of supported formats with:
ffmpeg -formats
Convert WAV to MP3, mix down to mono (use 1 audio channel), set bit rate to 64 kbps and sample rate to 22050 Hz:
| #include <iomanip> | |
| #include <iostream> | |
| #include <cstdlib> | |
| #include <vector> | |
| #include <cuda.h> | |
| #include <cudnn.h> | |
| #define CUDA_CALL(f) { \ | |
| cudaError_t err = (f); \ |
This is a draft for a decentralized web app for Stellar. It describes what the app should do. Some mock-ups showing these features would be welcomed.
Stellar Portal is a decentralized web application to access the Stellar Network. Its goal is to provide people full control over their account and do most of transaction, without the need of a backend, by only using Horizon API.
