• Touble when excuting the same ffmpeg command for many times

  4 janvier 2015, par morndust

  Decription

  when using the same ffmpeg command for a couple of times, some of those will succeed, but, some of those would failed, ffmpeg report Error while opening encoder for output stream #0:1 - maybe incorrect parameters such as bit_rate, rate, width or height or Invalid data found when processing input error.

  Input

  ffprobe

  Input #0, mov,mp4,m4a,3gp,3g2,mj2, from '/tmp/2137b8d42dcf4607a625755994133e69':

      Stream #0:0(eng): Video: h264 (High) (avc1 / 0x31637661), yuv420p, 1920x798 [SAR 1:1 DAR 320:133], 3255 kb/s, 23.98 fps, 23.98 tbr, 24k tbn, 47.95 tbc (default)
  
      Metadata:

      Stream #0:1(eng): Audio: aac (mp4a / 0x6134706D), 48000 Hz, 5.1, fltp, 192 kb/s (default)

      Metadata:

  Command

  /usr/local/bin/ffmpeg -i /tmp/2137b8d42dcf4607a625755994133e69 -f mp4 -b:v 3000k -r 24.0 -map_metadata -1 -vf scale=50:50 -y /tmp/foo.mp4

  Detail

  when i excute same command above 10 times, error would occur like 3 - 4 times.

  At the end, thanks for reading anyway, any answer would be appriciated.

• Print results at conclusion of bash 'for loop'

  4 juin 2016, par Matthew Schwarz

  I’m a beginner.
  I have a Bash script that embeds subtitles into mkv files if they exist in a directory.

  for i in *.mkv; do
  
      if [ -f "${i%mkv}"*"srt" ]; then
  
          ffmpeg -i "$i" -f srt -i "${i%mkv}"*"srt" -map 0:0 -map 0:1 -map 1:0 -c:v copy -c:a copy -c:s srt $i.output.mkv
  
          mv "${i%mkv}"*"srt" "${i%mkv}srt".old
  
          mv $i $i.old
  
          mv $i.output.mkv $i
  
      else
  
          echo $i "does not have srt file"
  
      fi
  
  done

  It looks for all .mkv files that have an associated .srt file and does some ffmpeg magic to it. If it does not find an associated .srt file it says that the .mkv file "does not have srt file."

  How can I make it so that at the conclusion of the for loop I get a print out of all the .mkv files that did have an .srt file and did successfully do all the other actions ?

  Thank you.
