  • 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) :

  • Applying same filter_complex many times before output [duplicate]

    19 août 2019, par Fabián

    This question already has an answer here :

    It’s not a duplicate. This is about using filter_complex, not -vf.

    In my video there’s an object that has shades of yellow (more orange-like) and a solid yellow as background.

    I need to output all frames into a png sequence, using a color key filter to replace the yellow from the background :

    ffmpeg -ss 4 -i original.mp4 -t 2 -filter_complex "[0:v]colorkey=0xfff31b:0.125:0[ckout]" -map "[ckout]" colorkey-%d.png

    This removes the specific color, but leaves some pints behind, and some items are yellow-themed, so blending value is a no-no for this scenario.

    I need to get rid of 4 specific yellow-colors from the frames : 0xfff31b, 0xfae56b, 0xfaec46 and 0xeee2a0, and I plan to run the same filter for specific colors before getting the final result.

    So first I tried this :

    ffmpeg -ss 4 -i original.mp4 -t 2 -filter_complex "[0:v]colorkey=0xfff31b:0.4:0[ckout1];[0:v]colorkey=0xfae56b:0.4:0[ckout2];[0:v]colorkey=0xfaec46:0.4:0[ckout3];[0:v]colorkey=0xeee2a0:0.4:0[ckout4]" -map "[ckout4]" colorkeyrefined-%d.png

    Then this :

    ffmpeg -ss 4 -i original.mp4 -t 2 -filter_complex "[0:v]colorkey=0xfff31b:0.4:0[ckout]" -filter_complex "[0:v]colorkey=0xfae56b:0.4:0[ckout]" -filter_complex "[0:v]colorkey=0xfaec46:0.4:0[ckout]" -filter_complex "[0:v]colorkey=0xeee2a0:0.4:0[ckout]" -map "[ckout]" colorkeyrefined-%d.png

    But both display the same error :

    Filter colorkey has an unconnected output.

    Is there a way to apply the colorkey feature 4 times (with the mentioned values) in one go ?

  • Bat file that extracts subtitle file then hard encodes the subtitle file into the original mkv file

    1er septembre 2019, par NolanWinsman

    My tv can play mkv files off of a flash drive but it cannot detect the subtitles files. I am trying to make a bat file that essentially takes the .srt file out of the mkv file then hard encodes it into the mkv file using ffmpeg. I am getting close but the naming is not working properly. For instance when it creates the subtitle file it names it infile.mkv.srt. When the file is encoded it is named infile.mkvEncoded.mkv. I am trying to get rid of the extra .mkv

    I am not great with variables in bat files so I am not exactly sure what to do. I added the "Encoded" part to the name of the file so that it doesn’t overwrite the original infile. I plan on just using bulk rename utility to get rid of that part unless there is a better way.

    My code is :

        DO (
    
    MKDIR Encoded_Files
    
    )
    
    FOR /F "tokens=*" %%G IN ('dir /b *.mkv') DO (
    
        ffmpeg -i "%%G" -vn -an -codec:s:0.1 srt "%%G.srt"
    
        ffmpeg -i "%%G" -vf "subtitles=%%G.srt" "%%GConverted"
    
        move *"%%~nG" "Encoded_Files"
    
            )

    The expected result would be infileEncoded.mkv*
