How to use
----------
Getting thumnails or videostream info
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
::
from ffvideo import VideoStream
def print_info(vs):
print '-' * 20
print "codec: %s" % vs.codec_name
print "duration: %.2f" % vs.duration
print "bit rate: %d" % vs.bitrate
print "frame size: %dx%d" % (vs.frame_width, vs.frame_height)
print "frame_mode: %s" % vs.frame_mode
vs = VideoStream('0.flv')
print_info(vs)
vs = VideoStream('0.flv',
frame_size=(128, None), # scale to width 128px
frame_mode='L') # convert to grayscale
print_info(vs)
frame = vs.get_frame_at_sec(2)
print frame.size
# PIL image, required installed PIL
frame.image().save('frame2sec.jpeg')
# numpy.ndarray, required installed numpy
print frame.ndarray().shape
Iterating over frame sequence
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
::
from ffvideo import VideoStream
for frame in VideoStream('0.flv'):
print frame.timestamp
