  • How to add text to a video with ffmpeg and python

    25 janvier 2013, par Jared Glass

    I've been trying to add text to an avi with ffmpeg and I can't seem to get it right.

    Please help :

    import subprocess
    

    
ffmpeg = "C:\\ffmpeg_10_6_11.exe"
    
inVid = "C:\\test_in.avi"
    
outVid = "C:\\test_out.avi"
    

    
proc = subprocess.Popen(ffmpeg + " -i " + inVid + " -vf drawtext=fontfile='arial.ttf'|text='test' -y " + outVid , shell=True, stderr=subprocess.PIPE)
    
proc.wait()
    
print proc.stderr.read()

  • FFmpeg drawtext over multiple lines

    22 novembre 2015, par Jared Glass

    I have the code :

    import subprocess , os
    

    
ffmpeg = "C:\\ffmpeg_10_6_11.exe"
    
inVid = "C:\\test_in.avi"
    
outVid = "C:\\test_out.avi"
    

    
if os.path.exists( outVid ):
    
os.remove( outVid )
    
proc = subprocess.Popen(ffmpeg + " -i " + inVid + ''' -vf drawtext=fontfile=/Windows/Fonts/arial.ttf:text="onLine1 onLine2 onLine3":fontcolor=white:fontsize=20 -y ''' + outVid , shell=True, stderr=subprocess.PIPE)
    
proc.wait()
    
print proc.stderr.read()
    
os.startfile( outVid )

    to write text to a video file. But I want to write out many lines of text instead of just having it all on the one line.

    Pls help. Thanks

  • Multi bitrate live HLS with FFmpeg on Windows

    16 mai 2014, par Nioreh

    I am trying to encode a live stream into Apple HLS for iPhone on windows. I was looking at different options and wowza can do it, but doesn’t support CDN distribution of HLS as far as I can see. Plus it costs a lot of money.

    What I did find was this site : http://www.espend.de/artikel/iphone-ipad-ipod-http-streaming-segmenter-and-m3u8-windows.html

    I can now set up a single bitrate stream easily, but my goal is an adapive multi-bitrate live stream. Is it possible ? For VOD content it can easily be accomplished with creating the different qualities then linking to them in a new m3u8, but how would this be done in live ?

    I can of course set up three quality live streams and link to them in an m3u8, but how will I get them GOP-aligned in this case ?

    My initial thought was to have one ffmpeg instance create all qualities and re-stream those outputs to new ffmpeg-instances that just remux and pipe to the segmenter. But I would need some way of streaming locally between instances. Can that be done ?

    If anyone has a nice solution to this, or can link to other software capable of live HLS on windows, I would appreciate any input.

    Have a great day !
    Regards
    Carl
