A cython implementation of an ffmpeg based player.
Project description
FFPyPlayer is a python binding for the FFmpeg library for playing and writing media files.
For more information: http://matham.github.io/ffpyplayer/index.html
To install: http://matham.github.io/ffpyplayer/installation.html
Usage example
Playing a file:
>>> from ffpyplayer.player import MediaPlayer
>>> import time
>>> player = MediaPlayer(filename)
>>> val = ''
>>> while val != 'eof':
... frame, val = player.get_frame()
... if val != 'eof' and frame is not None:
... img, t = frame
... # display img
Writing a video file:
>>> from ffpyplayer.writer import MediaWriter
>>> from ffpyplayer.pic import Image
>>> 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) for x in range(size)])
>>> img = Image(plane_buffers=[buf], pix_fmt='rgb24', size=(w, h))
>>> for i in range(20):
... writer.write_frame(img=img, pts=i / 5., stream=0)
Converting images:
>>> from ffpyplayer.pic import Image, SWScale
>>> w, h = 500, 100
>>> size = w * h * 3
>>> buf = bytearray([int(x * 255 / size) for x in range(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()
>>> map(len, planes)
