  • recording sound from webcam using ffmpeg

    1er août 2012, par user1545779

    Using ffmpeg arecord -L, I am able to identify my Logitech usb webcam as :

    hw:CARD=U0x46d0x821,DEV=0
    
    USB Device 0x46d:0x821, USB Audio
    
    Direct hardware device without any conversions
    
plughw:CARD=U0x46d0x821,DEV=0
    
    USB Device 0x46d:0x821, USB Audio
    
    Hardware device with all software conversions

    when I go into /dev/snd/by-id, the webcam is described as :

    usb-046d_0821_6813BFD0-00 -> ../controlC1

    I know that the command to use a sound device in ffmpeg is

    ffmpeg -f alsa -i $ALSA_DEVICE_NAME..

    I have tried

    ffmpeg -f alsa -i "hw:CARD=U0x46d0x821,DEV=0"

    and

    ffmpeg -f alsa  -i "plughw:CARD=U0x46d0x821,DEV=0"

    and in both cases I receive the same error message :

    ALSA lib pcm.c:2208:(snd_pcm_open_noupdate) Unknown PCM hw=CARD=U0x46d0x821,DEV=0
    
[alsa @ 0x9c96580] cannot open audio device hw=CARD=U0x46d0x821,DEV=0 (No such file or directory)
    
hw:CARD=U0x46d0x821,DEV=0: Input/output error

    I have also tried :

    ffmpeg -f alsa -i "usb-046d_0821_6813BFD0-00"

    and

    ffmpeg -f alsa -i "usb-046d_0821_6813BFD0-00,DEV=0"

    and have still received error message

    Could you please help in formulating the correct format of the command

  • SWF to PNG.. but merge all pngs inside into 1

    14 novembre 2014, par Jayden

    The title says it all,

    I’ve tried swftools and ffmepg but I don’t ’think’ they achieve what I need to do.

    Basically there is a SWF file that is made up of up to 60 images, them 60 images inside the SWF all are parts of an image that make up 1 final image or animation on an online game.

    I need to be able to download the swf as a png image with the same output it will look like on the virtual game - so not 60 images if seperate graphics, just one image with them all (merged ?) together.

    I am not even sure if this is possible to do in the commandline so if you understand any of this, please point me in the right direction.

    I am using Ubuntu 14.04
