• video not playing on Android (chrome) and iOS (safari)

  26 mars 2019, par lviggiani

  Hi I have a few video that DOES NOT play in Android (directly on Chrome) and on iOS (directly on Safari) but plays on Windows, Mac and Linux on any browser.

  Here is the ffprobe output

  Input #0, mov,mp4,m4a,3gp,3g2,mj2, from 'intro_sequence_01.mp4':

      Metadata:
  
        handler_name    : VideoHandler

  and here is the ffprobe output of another video that DOES play on Android and Chrome :

  Input #0, mov,mp4,m4a,3gp,3g2,mj2, from 'Torcia_960x540.mp4':
  
    Metadata:
  
      major_brand     : mp42
  
      minor_version   : 0
  
      compatible_brands: mp42mp41
  
      creation_time   : 2017-02-10T16:14:10.000000Z
  
    Duration: 00:00:11.52, start: 0.000000, bitrate: 10585 kb/s
  
      Stream #0:0(eng): Video: h264 (Main) (avc1 / 0x31637661), yuv420p(tv), 960x540 [SAR 1:1 DAR 16:9], 10576 kb/s, 25 fps, 25 tbr, 25k tbn, 50 tbc (default)
  
      Metadata:
  
        creation_time   : 2017-02-10T16:14:10.000000Z
  
        handler_name    : Mainconcept MP4 Video Media Handler
  
        encoder         : AVC Coding

  Both are .mp4 format and are using h264 codec.
  As far as I can see, I notice a difference in codec profile h264 (High 4:4:4 Predictive) vs Video: h264 (Main) and yuv444p vs yuv420p(tv) and on metadata section.

  I tried re-encoding the first video with ffmpeg but without success.
  Does anyone know why video1 is not compatible with Android and iOS and how to re-ffmpeg it to make it play ?
  Thanks !

• FFMPEG sound not playing in video converted from audio in browsers (chrome/firefox) except safari

  7 février 2019, par Bhavik Rathod

  Sound not playing in Video (mp4) converted from Audio (mp3), Below is my code

  I am using FFMPEG version 4.1

  ffmpeg -y -loop 1 -i background.jpg -i dia.mp3 -c:v libx264 -tune stillimage -pix_fmt yuv420p -c:a ac3_fixed -b:a 128k -shortest -vf "[in]drawtext=text=Hi:x=(w-text_w)/2:y=(h-text_h):fontfile=arial.ttf:fontsize=100:fontcolor=ffffff:alpha='if(lt(t,9.2763066666667),0,if(lt(t,9.2763066666667+1),(t-9.2763066666667)/1,if(lt(t,12.83428),1,if(lt(t,12.83428+1),(1-(t-12.83428))/1,0))))'" output.mp4 2>&1

  I have tried putting -movflags +faststart as an output option

  I am using ac3_fixed because i found that fix for handle memory management, My server is getting hang on using aac no video created nothing i have to restart instance to get back to work. by using ac3_fixed everything is perfect but issue is only sound playing in chrome and firefox.

  Below is full log while using aac

• Syntax error : "(" unexpected — with !(*.sh) in bash script [duplicate]

  25 janvier 2023, par Jmv Jmv

  I want to run a sh file :

  



  #!/bin/bash
for f in !(*.sh); do
    ffmpeg -i "$f" -vf yadif=0:-1 -threads 0 -c:v libx264 -pix_fmt yuv420p \
        -r 29.97 -b:v 3000k -s 1280x720 -preset:v slow -profile:v Main \
        -level 3.1 -bf 2 -movflags faststart /mnt/media/out-mp4/"${f%.mxf}.mp4"
    rm $f
done


  



  However, I get the following error :

  



  2: task1.sh: Syntax error: "(" unexpected


  



  If I try directly on the command line it works perfectly.

  



  


  the path and permissions are already reviewed

  


  



  Any idea what might be happening ?
