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)
[50000, 12500, 12500, 0]
