• How to ffmpeg a PNG image sequence in multiple subdirs to one mp4 ?

  17 août 2021, par MikeEcho

  I am trying desperately to get this working.

  


  I have multiple files in the format of : lago_20210817_1200.png, lago_20210817_1201.png and so on.

  


  I am having a folder for each day of the year. eg. lago_20210817_1200.png is the folder 2021, subfolder 08, subfolder 17.

  


  I have tried many different approaches :

  


  

  • ffmpeg -f concat -i filelist.txt -r 25 output.mp4

  


  • ffmpeg -f concat -i <(find '/home/user/lago/2021/08/*.png') -r 25 output.mp4

  &#xA;

  &#xA;

  But no approach seems to work !

  &#xA;

  I tried to create a filelist with :

  &#xA;

  find . -name '*.png' -exec echo "file '{}'" \;|sort -h|sort


  &#xA;

  the result looked promising

  &#xA;

  file './lago_20210813_1959.png'
file './lago_20210813_2000.png'
file './lago_20210813_2001.png'


  &#xA;

  I am getting very different error messages...

  &#xA;

  DTS -230584300921369, next:40000 st:0 invalid dropping
PTS -230584300921369, next:40000 invalid dropping st:0
DTS -230584300921369, next:40000 st:0 invalid dropping


  &#xA;

  or

  &#xA;

  [concat @ 0x562531fe6c80] Unsafe file name './lago_20210813_2155.png'


  &#xA;

  Could anyone lead me in the right direction, i am desperate.

• Audio on TS File Falls Progressively Out of Sync

  8 août 2021, par Steve Brown

  I would really appreciate some help with this...

  &#xA;

  I have a .ts file I've downloaded from the internet, when I play in Quicktime the video progressively falls behind the audio. It becomes noticeable after a couple of minutes and is a few seconds out after about ten minutes. It plays fine in VLC, but I want to be able to play on my AppleTV which does the same as Quicktime.

  &#xA;

  I've tried everything I can think of to resolve...

  &#xA;

  &#xA;
  • Convert with VLC, which does work, but every few seconds the audio skips.

  &#xA;

  • Convert with Handbrake, which again works, but every few seconds the audio skips like with VLC.

  &#xA;

  • Convert with FFMpeg using -async, but I get the same result again with the audio skips.

  &#xA;

  • Extracted the audio and video to two separate files and recreated a new file with FFMpeg, this makes no difference and is the same as playing the original file.

  &#xA;

  • Tried "stretching" the audio with FFMpeg using "aresample=async=1000", which synchronises but the audio is distorted.

  &#xA;

  &#xA;

  I think the audio skips I'm getting from the -async option are caused because the audio is being trimmed to sync with the video. What I want to do is adjust the video to fit with the audio and leave the audio unchanged.

  &#xA;

  I've tried to do this with -vsync, but the the results are the same as the original file. The FFMpeg user guide says the following :

  &#xA;

  With -map you can select from which stream the timestamps should be taken. You can leave either video or audio unchanged and sync the remaining stream(s) to the unchanged one.

  &#xA;

  But I cannot figure out the syntax. This is what I'm trying but the output is the same as the original...

  &#xA;

  ffmpeg -vsync 1 -I test.ts -map 0:1 -map 0:0 -y test.mp4

  &#xA;

  I've tried the above using vsync with 0, 1 and 2, but the result is still the same.

  &#xA;

  Could anyone please help me with the syntax to sync the video stream to the audio stream and leave the audio unchanged ? Or suggest an alternative method I could use ?

  &#xA;

  Any help would be really, really appreciated. Thanks.

  &#xA;

  Here is the ffprobe for test.ts...
