Inputting Audio Stream to FFMPEG
5 avril 2018, par WijayaI’m building a real time chat application with C# and ffmpeg.exe. My requirement is to get a memory stream from Microsoft Speech API and feed it to ffmpeg process in real time. I can take a memory stream from Microsoft Speech API. I’m using following code to create the memory stream.
using (MemoryStream stream = new MemoryStream())
{
MemoryStream streamAudio = new MemoryStream();
System.Media.SoundPlayer m_SoundPlayer = new System.Media.SoundPlayer();
_speechSynthesizerVisemesSender.SetOutputToWaveStream(streamAudio);
_speechSynthesizerVisemesSender.SetOutputToNull();
stream.WriteTo(proc.StandardInput.BaseStream);
}I’m already using another datapipe with another command to feed video content to ffmpeg. But I couldn’t find a stable solution to feed audio through a datapipe. This article briefly explains about audio datapipe. I’m using following command to stream audio.
"ffmpeg -re -f s16le -i pipe:wav -f mpegts udp://127.0.0.1:1234"
But it is not working with the datapipe. If I try the command with mp3 or wav file, it works.

How to remove hoax subtitles from mp4 files by ffmpeg ?
22 février 2020, par hamidiSometimes I get some mp4 files which include a stream of type data. When I play such files by vlc I see an additional subtitle which is not really a subtitle stream. For example it just includes "Chapter 03" ! Indeed the original mp4 file should include a video and an audio stream, while ffmpeg shows an additional data stream. This is the same stream vlc shows as an additional subtitle stream. Sometimes the file includes four streams, a video, an audio and a real subtitle stream. I don’t want to use -sn to remove this real subtitle. I just want to remove what to claim to be a subtitle stream and it’s not. They’re usually introduced to be a data stream, but vlc shows them as subtitle stream. I also don’t want to use -dn or -map_metadata -1 to remove data from mp4, because sometimes the mp4 includes chapters data which I don’t want to be removed. I just want to remove these hoax subtitles which are introduced as data.
How it’s possible to be done by ffmpeg ?
