Слияние аудио и видео потоков
Проблема с получением видео в высоком качестве со звуком с YouTube связана с использованием технологии DASH (Dynamic Adaptive Streaming over HTTP), которая не предусматривает наличие звуковой дорожки в потоке.
Решением является отдельное получение аудио и видео потоков и их последующее объединение с использованием программы ffmpeg.
Необходимо выбрать соответствующие аудио и видео потоки, затем использовать полученные URL в команде ffmpeg для запуска процесса загрузки и слияния потоков.

👩💻StackOverflow's 2019 Developer Survey Results👨💻
This year, nearly 90,000 developers took the survey. Here are some key results:
- For the 7th year in a row, #JavaScript is the most commonly used programming language, but #Python has risen in the ranks again.
- Over half of respondents had written their first line of code by the time they were 16, although this experience varies by country & by gender.
- Respondents were asked to think about the last time they solved coding problems with & without #StackOverflow. The data indicate that Stack Overflow saves a developer 30 to 90 minutes of time per week!
- About 65% of professional developers on Stack Overflow contribute to #OpenSource projects once a year or more.
- #Reddit & #YouTube were the most common answers to what social media site they use the most. (No #Telegram in the list! Wtf, StackOverflow!?)
