• Cannot concatenate videos ffmpeg [on hold]

  1er mai 2014, par Paul Prescod

  I have a bitmap that I would like to concatenate to the front of many videos as a sort of title screen or disclaimer screen.

  I try to turn it into a video with the same attributes as the rest of the video. So first I introspect the video :

  It seems to work okay. The video plays I would expect it to. The attributes turn out very similar. Here is a diff :

  But when I try to concatenate, I get errors.

  The output looks like it only has my disclaimer file in it, not the rest of the video.

  I’m also confused why it feels like it needs to "estimate" anything. It knows the input FPS and input durations. I’m not sure if this is the problem or not. Maybe its just a bug.

• Resize/cut video to a certain region

  18 mars 2023, par user3

  I have a series of videos (like 7k videos) in which I have to make a cut. Basically they are videos of people talking, and I have to cut said video and keep only the part of the lips.

  


  Does anyone know how to cut them ? I need to be able to automate it

  


  I'm looking for a command line software, where you can enter the coordinates and generates the new cropped video.

  


  Is it possible to do it maybe with ffmpeg ? I couldn't find a way yet

  


  Thank you !!!

  


  I have tried to do it using ffmpeg, but I couldn't find the way to introduce the region (by coordinates) which I want cut

  


• How could I add an overlay to a video based on mouse cursor coordinates ?

  5 mars 2023, par Dima

  I am making a web app, where the user clicks through some images while talking about them and pointing things out with the cursor. The audio, timestamps of image changes, and mouse cursor coordinates and times are sent to a php script which uses ffmpeg to make a slideshow from the images and audio.

  


  Then it runs another ffmpeg command to overlay a moving image representing the cursor hundreds of times to mimic the user's mouse movements.

  


  Here is an example command that inserts the mouse overlay :

  And this is just from a four second video. When I tried to do thirty seconds worth of mouse movements, the command would not even run because there were too many arguments. So I need to come up with another way to add a mouse overlay.

  


  An obvious choice would just be screen recording the user's screen to not have to add a mouse overlay because it would already be there. But then I don't think I can use full resolution pictures in the final video. It will be recordings of the images at whatever resolution the user's screen is set to. (Unless there's a way around this that I don't know about.)

  


  So how could I take a long list of mouse coordinates and timestamps and add an overlay representing a cursor to an existing video ?

  


  Edit : I tried putting everything from the filter-complex argument into a text file and calling it with filter_complex_script instead, as @БаярГончикжапов suggested in comments. Now it at least starts to run, but every time fails with this error :

  It only happens if there are more than 1553 arguments, and changing the arguments for 1553 and surrounding ones doesn't stop the error.
