示例1: cut_video
# 需要导入模块: from moviepy.video.io.VideoFileClip import VideoFileClip [as 别名]
# 或者: from moviepy.video.io.VideoFileClip.VideoFileClip import subclip [as 别名]
def cut_video(recording_path, datapack_dir):
# Read the start/end pattern
sr1, pattern_wav = wav.read('pattern.wav')
workingdir = tempfile.mkdtemp()
# Open the video file
clip = VideoFileClip(recording_path)
# Save its audio track temporarily on disk
clip.audio.write_audiofile(os.path.join(workingdir,"temp_audio.wav"))
# Read the audio samples, mix down to mono (if necessary), and delete the temporary audio track
sr2, recording_wav = wav.read(os.path.join(workingdir,"temp_audio.wav"))
if recording_wav.shape[1]>1:
recording_wav = numpy.mean(recording_wav,1)
shutil.rmtree(workingdir)
# Detect the start and end audio pattern
start, end = detect_start_end_times(pattern_wav, recording_wav, sr2, 4)
# Cut the video and write it into two separate video and audio files
clip.subclip(start+0.4, end).write_videofile(os.path.join(datapack_dir, 'video.mp4'), codec='libx264')
clip.subclip(start+0.4, end).audio.write_audiofile(os.path.join(datapack_dir,'audio.wav'))示例2: summarize
# 需要导入模块: from moviepy.video.io.VideoFileClip import VideoFileClip [as 别名]
# 或者: from moviepy.video.io.VideoFileClip.VideoFileClip import subclip [as 别名]
