• How to make all the edit in just one command ?

  2 août 2023, par bartche

  I'm new to ffmpeng so perdon me if it is a stupid question but I've been trying to put these 2 lines together and everytime it show me some different error.

  


  Command that runs first :

  


  ffmpeg -i input.mp4 -filter_complex pad="in_w:in_h+150:0:0",subtitles="subtitle.srt:force_style='Fontsize=24,PrimaryColour=&H000CCFF&,Bold,Shadow=12'" -vcodec libx264 output.mp4


  


  Command that runs second :

  


  ffmpeg -i output.mp4 -i input2.mp4 -filter_complex "[1][0]scale2ref=iw:iw*(1/2)[sat][ep];[ep][sat]vstack",pad="in_w:in_h+240:0:-120",drawtext="fontfile=/home/ubuntu/test/rhumasinera.ttf:text='My Text Here':fontcolor=red:fontsize=82:x=15:y=30",drawtext="fontfile=/home/ubuntu/test/rhumasinera.ttf:text='My Text Here':fontcolor=red:fontsize=82:x=15:y=880" -vcodec libx264 output2.mp4


  


  Not sure what I'm doing wrong since it works running the commands separateded. Wanting to do just in one code to make it faster.

• FFMPEG Converted MP3 file shows error "MPEG header 30 is missing"

  19 mars 2021, par Any Reservation

  I am using FFMPEG to convert all kind of media files to mp3. Files are being Converted Perfectly.
But files give error MPEG HEADER 30 is missing at 31576bytes. In All converted files I see this. And On Some MP3 Players, It do not play.

  


  Here is my conversion Command what i use

  


  $bitrate = '128k';    
$command = "ffmpeg -i /home/musicupl/public_html/musicuploads/SavetoAccount/abc.mp4 -ar 44100  -ac 2 -b:a ".$bitrate." -acodec libmp3lame /home/musicupl/public_html/musicuploads/SavetoAccount/Output.mp3;


  


  Is there any more tag to add MPEG Headers during the conversion. I have researched on this and found the -acodec libmp3lame but still same issue.

  


  Is there any other way or attribute to add in command line.
