    8 mai 2014, par Budgierless

    Just like what was talked about in this post : FFmpeg cannot recognize a preset even though it does exsist Ubuntu 12.04

    I have help, with deblockalpha which has been depreciated from ffmpeg for along time,
    i am no good with all this coding business, but would like someone to tell me how i can fix this outdated syntax, as i am getting this error :

    Unrecognized option ’deblockalpha’
    Failed to set value ’0’ for option ’deblockalpha’

    please see code below and advise ?

    $ffmpeg -i $input -r 30 -vcodec libx264 -s 512x288 -aspect 16:9 -b 1550k -maxrate 1800k -bufsize 4M -bt 1600k -flags +loop -cmp +chroma -deblockalpha 0 -deblockbeta 0 -refs 1 -coder 0 -me_method full -me_range 16 -subq 5 -partitions +parti4x4+parti8x8+partp8x8 -g 250 -keyint_min 25 -level 30 -trellis 2 -sc_threshold 40 -i_qfactor 0.71 -acodec libfaac -ab 128k -ar 44100 -ac 2 $addpre $output";

  • How to run this complex filter in Fluent FFMPEG ?

    11 septembre 2019, par Dan Weaver

    I’m trying to turn the following complex filter into a Fluent FFMPEG command but I can’t figure out how the mapping works.

    ffmpeg -i audio.mp3 -filter_complex "[0:a]showfreqs=s=200x100:colors=white|white,format=yuv420p[vid]" -map "[vid]" -map 0:a video.mp4

    This is what I have so far but I get an error about the ’vid’ stream.

    ffmpeg()
    
    .input("audio.mp3")
    
    .audioCodec("aac")
    
    .audioBitrate("320")
    
    .complexFilter(
    
      {
    
        filter: "showfreqs",
    
        options: { s: "200x100" },
    
        inputs: "0:a",
    
      },
    
      {
    
        filter: "format",
    
        options: { pix_fmts: "yuv420p" },
    
        outputs: ["vid"],
    
      }
    
    )
    
    .outputOptions(['-map "[vid]"', "-map 0:a"])
    
    .save(spectrumTmp)

    Error :

    ffmpeg exited with code 1: Stream map '"[vid]"' matches no streams.
    To ignore this, add a trailing '?' to the map.

    If I add a trailing ’ ?’ in outputOptions I get a file with no video stream.
