  • creating a virtual microphone Ubuntu 16.04 and streaming audio into it from RTSP IP camera

    22 avril 2017, par sunsetjunks

    I need to create both virtual webcam and virtual microphone on an Ubuntu 16.04 machine for use in web application using WebRTC through my web browser.

    I need to feed video and audio to these 2 virtual devices from an IP camera (RTSP stream).
    Playing RTSP stream directly in VLC works fine with both video and audio.

    For this, I have created a /dev/video1 with video4linux2.
    I am able to feed the IP camera to /dev/video1.

    ffmpeg -i rtsp ://ip_address:554/streaming/channels/101/ -f v4l2
    /dev/video1

    If I look in VLC player, I can select /dev/video1 as a video device, but I have only "hw:0,0" as audio device, which is my in-built microphone.

    How to properly feed such RTSP stream to both virtual webcam and virtual microphone ?

  • python3.6 ffmpeg call MacOSX (closed)

    10 avril 2017, par Awazleon

    I’m using Python 3.6 on MacOSX. I would like to use FFmpeg as Python sub-process. Everything works fine when using the OSX embedded Python 2.7 but using 3.6, this doesn’t work.
    I’ve got an error message because it doesn’t find FFmepg.

    raise FFExecutableNotFoundError("Executable ’0’ not found".format(self.executable))
    ffmpy.FFExecutableNotFoundError : Executable ’ffmpeg’ not found

    As you can se I tried with ffmpy but I also got the same result by invoking FFmpeg directly

    from subprocess import call
    call(["ffmpeg"])
    Traceback (most recent call last) :
    File "", line 1, in
    call(["ffmpeg"])
    File "/Library/Frameworks/Python.framework/Versions/3.6/lib/python3.6/subprocess.py", line 267, in call
    with Popen(*popenargs, **kwargs) as p :
    File "/Library/Frameworks/Python.framework/Versions/3.6/lib/python3.6/subprocess.py", line 707, in init
    restore_signals, start_new_session)
    File "/Library/Frameworks/Python.framework/Versions/3.6/lib/python3.6/subprocess.py", line 1326, in _execute_child
    raise child_exception_type(errno_num, err_msg)
    FileNotFoundError : [Errno 2] No such file or directory : ’ffmpeg’

    I installed the FFmpeg lib. by using Brew through Terminal. It was well installed but only visible by Python 2.7, not 3.6.

    Calling it from terminal is working :

    iMac-de-xxxxx : utilisateur$ ffmpeg

    ffmpeg version 3.2.4 Copyright (c) 2000-2017 the FFmpeg developers
    built with Apple LLVM version 8.0.0 (clang-800.0.42.1)
    configuration : —prefix=/usr/local/Cellar/ffmpeg/3.2.4 —enable-shared —enable-pthreads —enable-gpl —enable-version3 —enable-hardcoded-tables —enable-avresample —cc=clang —host-cflags= —host-ldflags= —enable-libmp3lame —enable-libx264 —enable-libxvid —enable-opencl —disable-lzma —enable-vda

    I’m not (yet) a Linux specialist but I think that a path is missing for 3.6 to find FFmpeg.
    Any clue to solve this annoying issue ?
