В это статье я расскажу как работать с аудио и видео файлами.
Работа с аудио файлами:
Иногда встречаю вопросы на форумах типа «как проиграть mp3 файл в C#?», авторам этих вопросов зачастую советуют использовать
Windows API или сторонние библиотеки, однако все намного проще! Существует класс
Audio из пространства имен
Microsoft.DirectX.AudioVideoPlayback, для проигрывания аудио-записей записей различного формата. Давайте разберем код.
Подключаем необходимую библиотеку:
using Microsoft.DirectX.AudioVideoPlayback;
Далее создаем экземпляр класса
Audio:
Audio player = new Audio(file_path);
где
file_path — путь к файлу.
И проигрываем сам файл:
player.Play();
Чтобы изменить громкость, необходимо обратиться к свойству
Volume
player.Volume = 0;
Примечания:
1. Свойство
Volume принимает значения от -10000 до 0.
2. По умолчанию библиотека
Microsoft.DirectX.AudioVideoPlayback отсутствует в проекте, по этому ее нужно добавить вручную (%
Profect_name% —
Add Referense —
Microsoft.DirectX.AudioVideoPlayback)
Кстати, раз уж мы говорим о работе со звуком, то позвольте Вам рассказать про еще один класс:
SpeechSynthesizer из пространства имен
System.Speech.Synthesis — он воспроизводит аудио звуки по тексту.
Подключаем библиотеку:
using System.Speech.Synthesis
Создаем экземпляр класса
SpeechSynthesizer и воспроизводим звук по тексту:
SpeechSynthesizer synth = new SpeechSynthesizer();
synth.SpeakAsync("Hello world");
Работа с видео файлами.
Класс
Video из того же пространства имен
Microsoft.DirectX.AudioVideoPlayback отвечает за работу с видео файлами. Все аналогично как и для класса
Audio.

Warning: strtotime() [function.strtotime]: It is not safe to rely on the system's timezone settings. You are *required* to use the date.timezone setting or the date_default_timezone_set() function. In case you used any of those methods and you are still getting this warning, you most likely misspelled the timezone identifier. We selected 'Europe/Moscow' for 'MSK/4,0/no DST' instead in /home/pyha/pyhapyha.ru/include/function.php on line 326
