У меня программа UVScreenCamera 6 выдает ошибку на Windows 10 64bit после окна «Конвертация звука… 0%»acmStreamOpen error
Как можно исправить эту ошибку?
В результате данной ошибки видеофайлы создаются, но в них совершенно нет звука.
Версии программы пробовал 6.6, а также 6.9 beta.
Решение проблемы: сохранить звук с полосой 128 Кбит/сек, а не 64 Кбит/сек.
Ошибка возникает, если в проекте 2 звуковых потока (например, запись шла с микрофона и с динамика). Библиотека конвертации звука не в состоянии преобразовать 2 потока пропускной способностью 64 К в один поток такой же пропускной способности.

проблема при окрытии нескольких преобразующих стримов (acmStreamOpen) из одного потока. первый открываеться нормально, остальные возвращают код ACMERR_NOTPOSSIBLE. При этом перед этим делаю acmStreamOpen с флагом ACM_STREAMOPENF_QUERY для все позжеоткрываемых стримов, код возврата MMSYSERR_NOERROR. Такое чувство что в потоке может быть открыт только один преобразующий стрим… помогите плз кто чем может….

Все зависит от конкретного acm-драйвера, который лежит в системе.
И запрос Query может быть там просто нереализован (или работать неправильно).
Проверять лучше так- открыл, закрыл в нормальном режиме.
Первая причина :
Неподдерживается внутреннее преобразование PCM (44100,2,16 -> 22050,1,16).
Следовательно надо завести еще один WAVEFORMATEX и сделать промежуточное преобразование.
Хотя его лучше написать самому. То что есть работает паршиво в смысле качества.
Вторая причина :
Все acm-драйвера MP3, что я видела не работают «во множественном числе».
Поддерживается только один поток.
In my application i have some Audio files those are in .wav Format, Here i am checking Each audio file BitRate , and if any file in below 128Kbps,i changed those files bit rate to 128kbps,by using Below code
int bitrate;
string FullPath = @Server.MapPath("~/AudioFiles/");
string[] filePaths = Directory.GetFiles(FullPath, "*.wav", SearchOption.AllDirectories);
for (int i = 0; i < filePaths.Length; i++)
{
string[] FileExt = filePaths[i].Split('\');
string[] Ext = FileExt[FileExt.Length - 1].Split('.');
string ExtFile = Ext[Ext.Length - 1];
if (ExtFile == "wav" || ExtFile == "WAV")
{
using (var reader = new WaveFileReader(filePaths[i]))
{
bitrate = reader.WaveFormat.AverageBytesPerSecond * 8;
reader.Dispose();
}
if (bitrate < 128000)
{
using (var reader = new WaveFileReader(filePaths[i]))
{
var newFormat = new WaveFormat(8000, 16, 1);
using (var conversionStream = new WaveFormatConversionStream(newFormat, reader))
{
WaveFileWriter.CreateWaveFile(Server.MapPath("~/AudioFiles/" + FileExt[FileExt.Length - 1]), conversionStream);
}
}
}
}
the above code is working for most of the files, But i get below error for some audio files.
how can i solve the issue?

You can typically only change one thing at a time with ACM, so if you have a 16kHz stereo file, you can’t go to an 8kHz mono file in one go.
So you need to see what WaveFormat your WaveFileReader has, and possibly do multiple conversion steps.
It may also be that your input WAV file is using a codec that ACM can’t decode. But again you’d need to examine your input WaveFormat to know that.

Error in acmStreamOpen(). No ACM filter found capable of decoding.
None of the drums under the drum kit packs make any sound, and when I tried to load up Piano 2, I repeatedly got this message: Error in acmStreamOpen(). No ACM filter found capable of decoding. I’m guessing this is a problem with the samples or something? It’s strange, because they all work on my other computer.
