有 PyMedia 的替代品吗

PyMedia 是否有替代方案来解码不同的视频格式并能够提取帧作为图像以进行进一步处理？

目前我必须能够执行以下操作（不是工作代码摘录，只是为了提供一个想法）：

demuxer = muxer.Demuxer(FORMAT)
streams = demuxer.parse(open(VIDEO).read(BUFFER_SIZE))
codec = vcodec.Decoder(CODEC)

for stream in streams:
    frame = codec.decode(stream[1])
    fdata = frame.convert(2)
    img = Image.fromstring("RGB", fdata.size, fdata.data)
    # ...further processing of image...

Is there an alternative to PyMedia to decode different video formats and be able to extract frames as images for further processing?

Currently I have to be able to do something like the following (not working code extract, just to give an idea):

demuxer = muxer.Demuxer(FORMAT)
streams = demuxer.parse(open(VIDEO).read(BUFFER_SIZE))
codec = vcodec.Decoder(CODEC)

for stream in streams:
    frame = codec.decode(stream[1])
    fdata = frame.convert(2)
    img = Image.fromstring("RGB", fdata.size, fdata.data)
    # ...further processing of image...
