• Combining Audio and Video file in python [duplicate]

  8 juin 2020, par yso

  I'm trying to understand how to us ffmpeg to combine video and audio files in python. I want to combine a .avi file and a .wav file to create a final .avi file. Is this the right approach ? I'm confused by the ffmpeg syntax.
Any help would be great.

  



  I was looking through this for help :
https://wiki.libav.org/Snippets/avconv#Combine_audio_and_video_file

  



  import ffmpeg
import subprocess

cmd = 'ffmpeg -i inputvideo.avi -i inputaudio.wav -c:v copy -c:a aac output_video_and audio.avi'
subprocess.call(cmd, shell=True)                                     # "Muxing Done
print('Muxing Done')


  


• Text backdrop by ass formatting

  14 septembre 2024, par Armen Sanoyan

  I want to add box behind a word using ass subtitles formatting. The box should have border radius. the ass file later will be used by ffmpeg.

  


  I have tried the BorderStyle=3 form stack ansers 1, 2 both of them do not provide a way to get rounded boxes. Also the BorderStyle=4 didn't work for me. In comments of last stack answer I found a possible reason that my libraries can be old, but anyway it doesn't seem that BorderStyle=4 will solve my problem of border radius. There is another way to achieve rounded box link to answer. I didn't figure it out how to install all the libs he explained there. Also the later answer seems to me over complicated. Is there an other way to make the borders of box rounded without suffering and pain ? I also tried drawing the box with Drawing commands like

  


  {\p1}m 0 0 s 100 0 100 100 0 100 c{\p0}


  


  But it still doesn't seem to be the best way to achieve rounded borders.
