  • DivX audio not decoded on DVD player

    8 août 2019, par Shaul

    Moved to https://video.stackexchange.com/questions/28225/divx-audio-not-decoded-on-dvd-player

    I am converting MP4 movie into AVI/DivX format. I plan to copy the AVI to a USB memory stick and plug it into my DVD player. My player is a Pioneer 3052 that supports USB input.

    I convert the file using ffmpeg without error messages. The output file is played correctly on my computer, including audio. I use "Movies & TVs" and "DIVX Player" for testing.

    When I try running it on my Pioneer the video and the subtitles are ok but there’s no audio. I know that there’s no issues with the hardware because videos converted with "FreeMake Video converter" do play audio.

    My command line is :

    .\ffmpeg.exe  "-i INFILE -c:v mpeg4 -vtag xvid -qscale:v 3 -c:a libmp3lame  -vf "scale=720:576:force_original_aspect_ratio=decrease,pad=720:576:(ow-iw)/2:(oh-ih)/2","subtitles=f=SRTFILE:charenc=ISO-8859-8:force_style=PrimaryColour=&H0000FFFF,Fontsize=16" OUTFILE

    I also experimented with -b:a 192k, -b:a 96k and -qscale:a 4 all leading to the same results.

    I wander what else to try.
    I add the report produced by ffprobe (for the output file) :

  • dnn : add layer pad which is equivalent to tf.pad

    29 juillet 2019, par Guo, Yejun
    dnn : add layer pad which is equivalent to tf.pad

    the reason to add this layer first is that vf_sr uses it in its
    
tensorflow model, and the next plan is to update the python script
    
to convert tf.pad into native model.

  • Python OpenCV real-time blurring with saving to output

    10 janvier 2024, par Oleg Novosad

    I have a live video stream via RTSP from my IP camera. I want to blur faces on that stream and output for mobile usage (HLS, H.264, etc). All this should ideally happen in real-time — with the minimum of resources consumed. I plan to deploy this later to some cloud, so the less money I spend on resources the better.

    &#xA;

    Currently I have a working solution like so :

    &#xA;

      &#xA;
    • I capture video using OpenCV

      • &#xA;

    • I update every frame with Gaussian Blur and save it to some folder

      • &#xA;

    • After some amount of frames I create MP4 / AVI / whatever video and make it accessible via HTTP URL

      • &#xA;

    • All of it is running on Django for now

      • &#xA;

    &#xA;

    I know I am doing something wrong, can someone suggest a better solution ?

    &#xA;
