Bindings for FFmpegSource

Project description

Example usage

If you don’t need to keep the index, create a video source right away:

>>> import ffms
>>> source_file = "test/x264.mkv"
>>> vsource = ffms.VideoSource(source_file)

Or you can create an indexer:

>>> indexer = ffms.Indexer(source_file)
>>> indexer.format_name
'matroska'
>>> indexer.track_info_list
[TrackInfo(type=0, codec_name='h264')]

Then create the index for the video source:

>>> index = indexer.do_indexing(-1)
>>> track_number = index.get_first_indexed_track_of_type(ffms.FFMS_TYPE_VIDEO)
>>> vsource = ffms.VideoSource(source_file, track_number, index)

Extract information from the video source:

>>> vsource.properties.NumFrames
8
>>> vsource.track.keyframes
[0, 5]
>>> vsource.track.timecodes
[0.0, 1000.0, 2000.0, 3000.0, 4000.0, 5000.0, 6000.0, 7000.0]

Retrieve a video frame:

>>> frame = vsource.get_frame(0)
>>> frame.EncodedWidth, frame.EncodedHeight
(128, 72)
>>> frame.planes[0]
array([16, 16, 16, ..., 16, 16, 16], dtype=uint8)

ffmsinfo.py is a demo script showing how this package can be used.
