  • FFMPEG "buffer queue overflow, dropping" with trim and atrim filters

    11 décembre 2016, par Prasanna Mahendiran

    In FFMPEG I am actually trimming and concating a 24 FPS video. When I apply a complex filter

    I am getting "buffer queue overflow, dropping" error. The resultant video and audio is still and not working properly.

    I tried with other stackoverflow questions but none of them worked. Also I think it is partially because the trim timings are mixed. That is start time can be anywhere between 0-end. When I make it strictly increasing it is working fine.

  • merge (video and sound) with (background music)

    27 novembre 2016, par Nir di

    i have video file vid.mpg that contain video and audio(speaking) and audio file aud.wav that contain background music.

    now, i want to merge them together.

    here is the command that i use :

    ffmpeg -i vid.mpg -i aud.mp3 -c:v copy  -filter_complex "[0:a]aformat = fltp:44100:stereo,apad[0a];[1]aformat=fltp:44100:stereo,volume=0.1[1a];[0a][1a]amerge[a]" -map 0:v -map "[a]" -ac 2 -t 0 out.mpg

    and this is the error that i get as response :

    [Parsed_amerge_4 @ 00000000003a36e0] No channel layout for input 1
    [Parsed_amerge_4 @ 00000000003a36e0] Input channel layouts overlap: output layou
    t will be determined by the number of distinct input channels
    [mpeg @ 000000000289a4e0] VBV buffer size not set, using default size of 130KB
    If you want the mpeg file to be compliant to some specification
    Like DVD, VCD or others, make sure you set the correct buffer size

    in addition i add the full log :

    C:\bina\ffmpeg\bin>ffmpeg -i vid.mpg -i
    aud.mp3 -c:v copy  -filter_complex "[1:a]aform
    at = fltp:44100:stereo,apad[0a];[1]aformat=fltp:44100:stereo,volume=0.1[1a];[0a]

  • Record Webcam as single JPG files [on hold]

    2 décembre 2016, par clic

    I have to record a Windows Directshow Webcam video stream (UHD, 30fps, yuyv422) as single JPG images. Performance is important, so preferably by using NVIDIA GPU acceleration via CUDA or something..

    What is the most simple but powerful solution, without having to buy proprietary software ?

    I had a look at ffmpeg, by recording as MJPEG and then using something like jpegtran to get the JPGs. I tried :

    ffmpeg -f dshow -video_size 1920x1080 -framerate 50 -vcodec mjpeg -i video="XI100DUSB-HDMI Video" out.avi

    But it results in an I/O error saying ’Could not set video options’. Maybe because of the yuyv422 pixel format of my Magewell USB dongles..

    Or is ffmpeg able to record as single JPGs directly somehow ?

    If someone has any other idea/solution besides ffmpeg, please let me know too ! Thanks !

    EDIT :

    I was now able to save JPGs directly, using webcamimg%04d.jpg instead of out.avi. But it’s always claiming about full real-time buffer. Raising the rtbufsize parameter doesn’t really help..
