    There is no more video written to the file at this time but ffmpeg is not stopping. If i stop it manual after 30 hours the file is only 26 hours 30 minutes long.

    How to reproduce:

    ffmpeg -progress recorder.progress -reconnect 1 -user_agent 'sdn/1.0' -i http://source/playlist.m3u8 -codec copy -bsf:a aac_adtstoasc record.mp4

  • Bash script to recursive find and convert movies

    24 mars, par Jacco

    in my large movie collection I would like to search for movies with the primary (first) audio track with DTS coding to be converted to Dolby.

    My problem would be the first track I think. My current bash script will list any movie containing a DTS track, but does not specify which track.

    #!/bin/bash
# My message to create DTS list
find /home/Movies -name '*.mkv' | while read f
do
if mediainfo "$f" | grep A_DTS; then
echo $f 
fi
done

    After that I would like to run this command

    ffmpeg -i $f -map 0:v -map 0:a:0 -map 0:a -map 0:s -c:v copy -c:a copy -c:s copy -c:a:0 ac3 -b:a:0 640k $f

    or is there a way to move all the audio tracks down and adding the new AAC track?

    ###Progress

    Thanks to @llogan I have finetuned the bash to find the required files.

    #!/bin/bash
# My DTS conversion script
# credits to llogan

find /Mymovies -name '*.mkv' | while read f
do
 if ffprobe -v error -select_streams a:0 -show_entries stream=codec_name -of csv=p=0 "$f" | grep dts; then
 echo "$f"
fi
done

    Now digging into the command I think I may have a working command. Anybody spot a problem?

    ffmpeg -i $f
      -map 0:v -c:v copy
      -map 0:a:0? -c:a:0 ac3
      -map 0:a:0? -c:a:1 copy
      -map 0:a:1? -c:a:2 copy
      -map 0:a:2? -c:a:3 copy
      -map 0:a:3? -c:a:4 copy
      -map 0:a:4? -c:a:5 copy
      -map 0:a:5? -c:a:6 copy
      -map 0:a:6? -c:a:7 copy
      -map 0:a:7? -c:a:8 copy
      -map 0:a:8? -c:a:9 copy
      -map 0:s? -c copy
      -b:a:0 640k
/tmp/output.mkv
mv $f /home/DTS_BACKUP/
mv /tmp/output.mkv $f
rm /tmp/output.mkv

    So the end result would look like:

    #!/bin/bash
# My DTS conversion script
# credits to llogan
find /Mymovies -name '*.mkv' | while read f
do
 if ffprobe -v error -select_streams a:0 -show_entries stream=codec_name -of csv=p=0 "$f" | grep dts; then

ffmpeg -i $f
          -map 0:v -c:v copy
          -map 0:a:0? -c:a:0 ac3
          -map 0:a:0? -c:a:1 copy
          -map 0:a:1? -c:a:2 copy
          -map 0:a:2? -c:a:3 copy
          -map 0:a:3? -c:a:4 copy
          -map 0:a:4? -c:a:5 copy
          -map 0:a:5? -c:a:6 copy
          -map 0:a:6? -c:a:7 copy
          -map 0:a:7? -c:a:8 copy
          -map 0:a:8? -c:a:9 copy
          -map 0:s? -c copy
          -b:a:0 640k
/tmp/output.mkv
mv $f /home/DTS_BACKUP/
mv /tmp/output.mkv $f
rm /tmp/output.mkv

fi
done

  • Convert DTS to AC3 but only if there is no AC3 track already present in container

    24 mars, par Domagoj

    I have sound system that does not support DTS only AC3. I'm automating the process using bash that detects when movie was added to folder, downloads subtitles and converts audio track to AC3 using this command (one part of it):

    ffmpeg -i "{{episode}}" -map 0:v -map 0:a:0 -map 0:a -map 0:s -c:v copy -c:a copy -c:s copy -c:a:0 ac3 -b:a:0 640k "{{directory}}"/{{episode_name}}temp2.mkv

    This works without issue and I end up with a .mkv file that contains original DTS audio track and newly created AC3 audio track. The issue is that some files already contain both AC3 and DTS tracks and in those cases I end up with two AC3 tracks and one DTS track. Another issue is that this command is triggered every time there is update to subtitles. So it's possible that the command will execute multiple times in a period of a few days and the container will have X number of the AC3 tracks.

    I need a way to detect if file already contains AC3 track before I initiate command from above, but I'm not sure what the command would be. Any help is appreciated!

  • Why is using ffmpeg to convert MXF files failing ?

    24 mars, par Marinaio

    I have an MXF video

    I googled syntax to convert to mov and ran it in Mobaxterm on Win10.

    "/drives/c/Program Files (x86)/ffmpeg/bin/ffmpeg.exe" -i Clip0001.MXF -c:v libx264 -c:a aac -ab 384k -sn -strict -2 output.mov

    I view it in VideoLan and it looks great.

    I load it into Magix Movie Studio 15 and audio is fine, but video is green!

    ffmpeg output.mov....shows me:

    Stream #0:0(eng): Video: h264 (High 4:2:2) (avc1 / 0x31637661), yuv422p, 1920x1080 [SAR 1:1 DAR 16:9], 4530 kb/s, 29.97 fps, 29.97 tbr, 30k tbn, 59.94 tbc (default)

    Even this does not work:

    ffmpeg.exe -i Clip0001.MXF output.mov

    Any suggestions on converting this?

    Edit1:

    Here is what it looks like in the editor: enter image description here

    Edit2: Try this and it works, but quality is terrible.

    ffmpeg.exe" -i Clip0001.MXF -c:v mpeg4 -c:a aac -ab 384k -sn -strict -2 output.mov

  • Convert audio files to mp3 using ffmpeg [closed]

    I guess that the mp3 codec isn't installed. Am I on the right track here?
