FFPyPlayer is a python binding for the FFmpeg library for playing and writing media files.
For more information: https://matham.github.io/ffpyplayer/index.html
To install: https://matham.github.io/ffpyplayer/installation.html
Warning
Although the ffpyplayer source code is licensed under the LGPL, the ffpyplayer wheels for Windows and linux on PYPI are distributed under the GPL because the included FFmpeg binaries were compiled with GPL options.
If you want to use it under the LGPL you need to compile FFmpeg yourself with the correct options.
Similarly, the wheels bundle openssl for online camera support. However, releases are not made for every openssl release, so it is recommended that you compile ffpyplayer yourself if security is a issue.
Playing a file:
>>>fromffpyplayer.playerimportMediaPlayer>>>importtime>>>player=MediaPlayer(filename)
>>>val=''>>>whileval!='eof':
... frame, val=player.get_frame()
... ifval!='eof'andframeisnotNone:
... img, t=frame
... # display imgWriting a video file:
>>>fromffpyplayer.writerimportMediaWriter>>>fromffpyplayer.picimportImage>>>w, h=640, 480>>># write at 5 fps.>>>out_opts= {'pix_fmt_in':'rgb24', 'width_in':w, 'height_in':h,
... 'codec':'rawvideo', 'frame_rate':(5, 1)}
>>>writer=MediaWriter('output.avi', [out_opts])
>>># Construct image>>>size=w*h*3>>>buf=bytearray([int(x*255/size) forxinrange(size)])
>>>img=Image(plane_buffers=[buf], pix_fmt='rgb24', size=(w, h))
>>>foriinrange(20):
... writer.write_frame(img=img, pts=i/5., stream=0)Converting images:
>>>fromffpyplayer.picimportImage, SWScale>>>w, h=500, 100>>>size=w*h*3>>>buf=bytearray([int(x*255/size) forxinrange(size)])
>>>img=Image(plane_buffers=[buf], pix_fmt='rgb24', size=(w, h))
>>>sws=SWScale(w, h, img.get_pixel_format(), ofmt='yuv420p')
>>>img2=sws.scale(img)
>>>img2.get_pixel_format()
'yuv420p'>>>planes=img2.to_bytearray()
>>> [len(plane) forplaneinplanes]
