• How can I use FFMPEG in my discord bot thats on github

  21 septembre 2019, par Waldre

  I moved my discord bot to GitHub and Heroku today, everything works fine but I get this error that causes the bot to stop working

  I have already tried adding FFmpeg as a submodule by doing this :

  git submodule add git://source.ffmpeg.org/ffmpeg FFmpeg but it still doesn't work

  These are the errors I’m getting

• How to make TIME subtitles(.srt, .smi etc) with frame unit

  3 septembre 2019, par kylesong

  I want to create a Python script that make subtitle (a ticking timecode).

  I have an h.264 binary file that has timestamp in each frame. so I want to parse this timestamp and make the subtitle with it.

  Here’s what I’ve tried with ffmpeg below.

  ffmpeg -y -i video.avi -vf "drawtext=fontfile=C:\Windows\Fonts\consolab.ttf: fontsize=12:fontcolor=yellow: box=1:boxcolor=black@0.4: text='TIME\: %{pts\:gmtime\:1561939200}':x=(w-tw)/2:y=(h-th)/2" test.avi

  Output .avi is okay with the timestamp, but, I needed to re-encode the source video file which takes a lot of time.
  So, I want to use a different way, which is creating subtitles.

  Question is, is there any way to make subtitle with frame time ? or useful info to fill me in ?

  The current result :
  

  

  The expected result :
  

  

• Applying same filter_complex many times before output [duplicate]

  It’s not a duplicate. This is about using filter_complex, not -vf.

  In my video there’s an object that has shades of yellow (more orange-like) and a solid yellow as background.

  I need to output all frames into a png sequence, using a color key filter to replace the yellow from the background :

  ffmpeg -ss 4 -i original.mp4 -t 2 -filter_complex "[0:v]colorkey=0xfff31b:0.125:0[ckout]" -map "[ckout]" colorkey-%d.png

  This removes the specific color, but leaves some pints behind, and some items are yellow-themed, so blending value is a no-no for this scenario.

  I need to get rid of 4 specific yellow-colors from the frames : 0xfff31b, 0xfae56b, 0xfaec46 and 0xeee2a0, and I plan to run the same filter for specific colors before getting the final result.

  So first I tried this :

  ffmpeg -ss 4 -i original.mp4 -t 2 -filter_complex "[0:v]colorkey=0xfff31b:0.4:0[ckout1];[0:v]colorkey=0xfae56b:0.4:0[ckout2];[0:v]colorkey=0xfaec46:0.4:0[ckout3];[0:v]colorkey=0xeee2a0:0.4:0[ckout4]" -map "[ckout4]" colorkeyrefined-%d.png

  Then this :

  ffmpeg -ss 4 -i original.mp4 -t 2 -filter_complex "[0:v]colorkey=0xfff31b:0.4:0[ckout]" -filter_complex "[0:v]colorkey=0xfae56b:0.4:0[ckout]" -filter_complex "[0:v]colorkey=0xfaec46:0.4:0[ckout]" -filter_complex "[0:v]colorkey=0xeee2a0:0.4:0[ckout]" -map "[ckout]" colorkeyrefined-%d.png

  But both display the same error :

  Filter colorkey has an unconnected output.

  Is there a way to apply the colorkey feature 4 times (with the mentioned values) in one go ?
