  • ffmpeg with Axis P1347 returns 400 Bad Request, but Axis 1357 works

    3 mai 2016, par steampowered

    I have two cameras : an Axis P1347 and an Axis P1357. ffmpeg gets a 400 Bad Request on the P1347 but everything works fine with the P1357.

    I am able to successfully stream rtsp video using vlc from an Axis P1347 Camera using the following url :

    rtsp://10.8.3.85:554/axis-media/media.amp?videocodec=h264&audio=1

    However, this same url in ffmpeg gives the following for the Axis P1347 Camera :

    root@ubuntu4-virtual-machine:/home/ubuntu4# ffmpeg -re -v verbose  -i "rtsp://10.8.3.85:554/axis-media/media.amp?videocodec=h264&audio=1"

    The same ffmpeg command works great with the nearly identical Axis P1357 Camera :

       Stream #0:1: Audio: aac (LC), 16000 Hz, mono, fltp

    Obviously rtsp is turned on and working if vlc can display video, correct ? So why does VLC work with the camera, but not ffmpeg ? Note ffmpeg is installed and works correctly with a similar camera.

  • ffmpeg overlay not showing on first frame

    5 mai 2016, par Nic Wilson

    I’m trying to use ffmpeg to overlay a 720x720 video (previd.mp4) onto a background image (bg.jpg). I have it working except that the first frame of the video that is created shows the background only for a frame before the overlay video is shown on top of it.

    This is what I’m using to create the video and overlay :

    ffmpeg -loop 1 -i bg.jpg -i previd.mp4 -filter_complex "[1:v]scale=-1:1080[a]; [0:v][a]overlay=(main_w/2)-(overlay_w/2):0:shortest=1[video]" -map "[video]" -map 1:a -codec:a copy vid.mp4

  • FFmpeg stream map doesn't work any more

    5 mai 2016, par Tommy

    I have troubles to get for example first stream from MKV file. Strange is that my script used to work on older Debian and same code doesn’t work on Debian 8. I checked also manual and there is the same :

    ffmpeg -i INPUT -map 0:1 out.wav

    Do you know what is wrong ?

    Thank you
