        "description": "ffms2 \u2013 Python bindings for FFmpegSource\n========================================\n\nThis project is a fork that supports more recent versions of FFMS.\nThe original repository can be found at https://bitbucket.org/spirit/ffms.\n\nExample usage\n-------------\n\nIf you don't need to keep the index, create a video source right away:\n\n```python-console\n>>> import ffms2\n>>> source_file = \"test/CINT_Nik_H264_720_512kb.mp4\"\n>>> vsource = ffms2.VideoSource(source_file)\n```\n\nOr you can create an indexer:\n\n```python-console\n>>> indexer = ffms2.Indexer(source_file)\n>>> indexer.format_name\n'mov,mp4,m4a,3gp,3g2,mj2'\n>>> indexer.track_info_list\n[TrackInfo(type=0, codec_name='h264'), TrackInfo(type=1, codec_name='aac')]\n```\n\nThen create the index for the video source:\n\n```python-console\n>>> for track in indexer.track_info_list:\n>>>     indexer.track_index_settings(track.num, 1, 0)\n>>> index = indexer.do_indexing2()\n>>> track_number = index.get_first_indexed_track_of_type(ffms2.FFMS_TYPE_VIDEO)\n>>> vsource = ffms2.VideoSource(source_file, track_number, index)\n```\n\nExtract information from the video source:\n\n```python-console\n>>> vsource.properties.NumFrames\n1430\n>>> vsource.track.keyframes[:5]\n[0, 12, 24, 36, 48]\n>>> vsource.track.timecodes[:5]\n[0.0, 41.666666666666664, 83.33333333333333, 125.0, 166.66666666666666]\n```\n\nRetrieve a video frame:\n\n```python-console\n>>> frame = vsource.get_frame(0)\n>>> frame.EncodedWidth, frame.EncodedHeight\n(416, 240)\n>>> frame.planes[0]\narray([41, 41, 41, ..., 41, 41, 41], dtype=uint8)\n```\n\nAudio stuff:\n\n```python-console\n>>> track_number = index.get_first_indexed_track_of_type(ffms2.FFMS_TYPE_AUDIO)\n>>> asource = ffms2.AudioSource(source_file, track_number, index)\n>>> aprops = asource.properties\n>>> aprops.SampleRate, aprops.BitsPerSample, aprops.Channels\n(48000, 16, 2)\n>>> min_audio, max_audio = float(\"inf\"), float(\"-inf\")\n>>> for audio in asource.linear_access(rate=100):\n...     if audio.min() < min_audio:\n...         min_audio = audio.min()\n...     if audio.max() > max_audio:\n...         max_audio = audio.max()\n>>> min_audio, max_audio\n(-16191, 18824)\n```\n\n`ffmsinfo.py` is a demo script showing how this package can be used.\n\nInstallation\n------------\n\nTo install the package for Python 3, use:\n\n```console\n$ ./setup.py install\n```\n\nPrerequisites\n-------------\n\n- [Python 3.2+](http://www.python.org)\n- [FFmpegSource](https://github.com/FFMS/ffms2)\n- [numpy](http://www.numpy.org)\n\nThe API was designed to be an object-oriented and Pythonic version of the\noriginal [FFmpegSource\nAPI](https://github.com/FFMS/ffms2/blob/master/doc/ffms2-api.md).",
