• ffmpeg related : [NULL @ 00000000000a9500] Unable to find a suitable output format for 'ΓÇôI' ΓÇôI : Invalid argument

  23 juillet 2018, par Prakash Pai

  I’m running the command

  "C :\Program Files\ImageMagick-7.0.8-Q16\ffmpeg" -framerate 24 –I BWW_%03d.png output_24.mp4
  ffmpeg version 3.4 Copyright (c) 2000-2017 the FFmpeg developers
  built with gcc 7.2.0 (GCC)

  and I get the above error. i.e.

  [NULL @ 00000000000a9500] Unable to find a suitable output format for ’ΓÇôI’
  ΓÇôI : Invalid argument

  I get the same issue when I run the ffmpqg installed from the ffmpeg.org download site as well.

  How can I resolve this ? Thanks.

  The start of Input #0 is 648413.295900, and the start of Input #1 is 648413.884042.

  I’ve been able to keep the audio and video in very close sync by subtracting the two values (which I assume are wallclock values), and using the asetpts audio filter to delay the audio stream of the recorded mpeg-2 file by that amount.

  I’d like to be able to do this exactly though, and that value changes slightly every time I start a new capture. Not to mention, I’d like to be able to do this reliably on different machines, where I assume the value will most likely be different, thus using a calculation as opposed to a fixed number is obviously the best option, if it’s possible.

  Is there a way to subtract the wallclock start time of input #0 from the wallclock start time of input #1 ? I’d like to do this inside the asetpts filter, instead of manually finding the difference from a previous run, which again is slightly different every time...

  I was thinking something like -af asetpts=PTS-([1:0]RTCSTART-[0:0]RTCSTART)/TB might work, but I have no idea how to format it.

  Thanks in advance !

• FFMpeg frame drop when merging a image sequence and overlaying during video creation process

  29 juillet 2018, par Killer

  I have reviewed both the answer as mentioned in Similar Issue But still, I am having some frame drops.

  Here is what I was doing :
  Question 1
  Question 2

  Currently, I am showing a few images (one after another each with
  duration ’x’) on a sample background along with a music playing in the
  background.

  This is the command I am using to get the desired functionality :

  ffmpeg 
  
  -hide_banner 
  
  -y 
  
  -loop 1 
  
  -r 1 
  
  -i /data/user/0/mojo.wed.com.wedmojo/cache/wedding_video/Images/IMG_WED_MOJO_WEDDING_FRAME.png 
  
  -r 1/4 
  
  -i /data/user/0/mojo.wed.com.wedmojo/cache/wedding_video/Images/IMG_WED_MOJO_SELECTED_IMAGE_%d.png 
  
  -filter_complex overlay=(W-w)/2:(H-h)/2,drawtext=text=WedMojo:fontcolor=white:fontfile=/data/user/0/mojo.wed.com.wedmojo/cache/wedding_video/Files/FONT_WED_MOJO_WEDDING.ttf:fontsize=30:x=w-tw-20:y=h-th-20 
  
  -c:v libx264 
  
  -profile:v high 
  
  -crf 17 -pix_fmt yuv420p 
  
  -preset ultrafast 
  
  -t 16 -strict experimental 
  
  -r 24 
  
  /data/user/0/mojo.wed.com.wedmojo/cache/wedding_video/Videos/VID_WED_MOJO_WEDDING_OUTPUT.mp4

  note : -r 1/4 for each image to be shown for 4 sec.

  I have checked the format of the images. All are the same. Also on changing preset and other values, the problem seems to be same. Log states drop=0, however, there are gaps as the overlay image is removed in between.

  Video sample with the duration set to 4 i.e each image to be set for 4 seconds.

  -> -> Video Output with 4 sec duration for each image

  However, there are no frame drops when the duration set to 1 or 2.

  -> -> Video Output with 2 sec duration for each image, ignore zoompan

  Log details :
