  • Ubuntu stuck when trying to compile ffmpeg for android

    7 septembre 2015, par Yehuda

    I trying to compile ffmpeg for android.
    I downloaded an example project of ffmpeg for android(https://github.com/bbcallen/ijkplayer) and when I tried to compile ffmpeg with the command :

    ./compile-ffmpeg.sh clean
    
./compile-ffmpeg.sh all

    Ubuntu is completely got stuck !
    I had to do restart..

    So I tried another project (https://github.com/appunite/AndroidFFmpeg) and the same thing happened...

    I don’t really know whats happens but I think that it related to the make command and to the ndk compilation..

    Who can help me to deal with this ? It’s really frustrating..
    If it’s matter it was on a virtual machine with Ubuntu desktop 64 bit..

    Thank you :)

  • ffmpeg not stopping when input is dshow

    15 août 2016, par TheSHEEEP

    We were recording a video by specifying a named pipe as input for video frames, like this :

    ffmpeg -r 30 -f rawvideo -pix_fmt bgra -s 640x480 -i namedPipe [... output options] out.mp4

    It works well, and FFmpeg stops once the named pipe is closed, as is desired.

    However, then we also want to record live audio from directshow, like this :

    ffmpeg -r 30 -f rawvideo -pix_fmt bgra -s 640x480 -i namedPipe -f dshow -i audio=virtual-audio-capturer [... output options] out.mp4

    This also works, but the problem is that the process now does not stop any more once we close the named pipe for the video frames.
    My guess is that ffmpeg still gets audio input and thus just keeps running.

    How can I change the FFmpeg command so that it stops once the video frames keep coming ?

  • IP Camera rtsp using v4l2loopback to video0

    11 septembre 2022, par slepax

    The main purpose of this exercise is to get an IP Camera feed into linphone when making a video call from a RPI by emulating a virtual webcam on /dev/video0.

    


    First to start with I tested the following command :

    


    sudo ffmpeg -y -re -acodec pcm_s16le -rtsp_transport tcp -i rtsp://admin:@10.1.5.52:554 -vcodec copy -an test.mp4


    


    Here I get a test.mp4 file that I can open and play just fine.

    


    Next step I used the following command to send the stream from the IP Camera to /dev/video0 :

    


    sudo ffmpeg -rtsp_transport tcp -i rtsp://admin:@10.1.5.52:554 -pix_fmt yuv420p -f v4l2 /dev/video0


    


    On linphone this works and the image is available but the image does not update. Almost like there is only 1 second of data passing through and then no more updates.

    


    I then tried a simpler command using ffmpeg :

    


    sudo ffmpeg -i /dev/video0 test.mp4


    


    This does not work either. I get a file created but it is not playable.

    


    Is there anything that I am doing wrong ?
When I launch the ffmpeg/rtsp command the bitrate always show N/A, it doesn't matter whether I have linphone or ffmpeg trying to access /dev/video0.
