  • Video Capture using Beaglebone black (Raw video to MP4)

    21 mars 2014, par user3435464

    Good Day,

    I just captured a raw video using the command from my PS3 Eye Camera on my beagleboard. I had captured about 10s of raw video in 320*240, and the format used was YUYV

    ./capture -f -c 300 -o > output.raw

    I successfully got the raw video (was about 40MB)

    Now, I needed to figure out how to convert this raw video to an mp4 file : I have been trying out various ffmpeg commands but to no avail

    root@beaglebone:~/Desktop/boneCV# ffmpeg -vcodec rawvideo -f rawvideo -pix_fmt yuv422p -        i output.raw -s 320x240 -r 25

    -vcodec libx264 -an -vpre slower -crf 25

    This is the ffmpeg log of my camera type :

    ffmpeg -f video4linux2 -list_formats all -i /dev/video0      
    
[video4linux2 @ 0x2db80] R :   yuyv422 :                 YUYV : 320x240 640x480

    Does anyone have experience converting such raw video formats to MP4 ?
