  • avconv/ffmpeg simultaneously stream from usb webcam and save video onto disk

    27 novembre 2017, par BojowyZajaczek

    I need to simultaneously stream/broadcast (over rtmp) and save video (with audio) from my USB webcam. The webcam is Logitech c920 which have hardware h.264 encoder.

    I don’t want to reencode the media, so I’m using the -c:v copy option.

    The whole script looks like below :

    #! /bin/bash
    

    
SOURCEV="/dev/video0"
    
SOURCEA="hw:1"
    

    
FILE_TO_SAVE="Archive/file_to_save.mp4"
    
YOUTUBE_URL="rtmp://x.rtmp.youtube.com/live2"
    
KEY="my-secret-key"        
    

    
avconv -f alsa -ac 2 -r 44100 -i $SOURCEA \
    
-s 1920x1080 -r 24 -c:v h264 -i "$SOURCEV" \
    
-ar "44100" -r:v 24 -c:a aac -c:v copy -s 1920x1080 -f mp4 "$FILE_TO_SAVE" \
    
-g $FPS*4 -ar "44100" -b:a "128k" -ac 2 -r 24 -c:a aac -c:v copy -s 1920x1080 -f flv "$YOUTUBE_URL/$KEY"

    This method "works" - it means’ it can stream content and save it to disk, but the problem with this method is that file video relies on the stream. For example if the Internet connection is too slow, the saved file will have low FPS. If the Internet connection is interrupted the "recording" of video file is stopped.

    Can anyone help me with making this two streams independent ?

    The whole things is happening on raspberrypi 3 so computing power is highly limited.

  • Added imageQuality option, which is passed to the canvas.toBlob method to save resized images.

    Added imageQuality option, which is passed to the canvas.toBlob method to save resized images.

    Removed mozGetAsFile code from the image processing plugin, as Firefox
    
supports setting the FormData filename since version 22 (current
    
version being 25).

  • How to use gstreamer to save webcam video to file ?

    21 juin 2017, par sav

    I’ve been trying to get emgu to save same webcam video to file

    The problem is opencv only ssupports avi, and avi does not seem to suit a format like X264 very well.

    Could I use Gstreamer to do this for me in C ?

    It would be good if I could choose the file format and container type too. It would be good if I could use a format like schrodinger dirac.

    I’m new to GStreamer so I’m not quite sure if I’m on the right track here.

    EDIT

    I’ve managed to capture the webcam video using

    gst-launch-0.10 ksvideosrc ! autovideosink

    Now how to transcode this to a format like H264 or dirac ...?

    EDIT

    gst-launch-0.10 ksvideosrc num-buffers=10 ! decodebin2 !
    ffmpegcolorspace ! x264enc ! matroskamux ! filesink
    location=video.mkv

    This seems to create a file, but VLC player can’t read it.
