我正在寻找一个简短的Python脚本,根据我使用时间码创建的.txt文件自动为我进行一些视频剪辑。我为此使用以下代码:
#!/usr/bin/env python3
import subprocess
first = True
with open('VideoSlicepoints_Python.txt') as f:
for line in f.readlines():
if first:
first = False
else:
filename, VideoDing_Timecode, Video_R4Start, Video_R4End, Video_R24Start, Video_R24End, Video_R0plus15 = line.strip().split(';')
cmd = ['ffmpeg', '-i', filename, '-ss', Video_R4Start, '-to', Video_R4End, '-c', 'copy', '"S:/_RobotThesis/VideoRounds/' + filename[:-4] + '_r4' + filename[-4:] + '"']
print(" ".join(cmd))
subprocess.run(cmd, stderr=subprocess.STDOUT)
当它尝试循环到视频时,这会向我返回以下错误:
[NULL @ 0000027cddf8a100] Unable to find a suitable output format for '"S:/_RobotThesis/VideoRounds/log1_front_r4.MTS"'
"S:/_RobotThesis/VideoRounds/log1_front_r4.MTS": Invalid argument
现在,我认为这是一个格式问题,但是当我直接输入命令时(在CMD提示符中可见),它就可以正常工作:
ffmpeg -i log1_front.MTS -ss 09:37.1 -to 11:37.1 -c copy "S:/_RobotThesis/VideoRounds/log1_front_r4.MTS"
作为参考,这是我正在使用的.txt文件的摘录(它基于csv文件,这就是为什么它具有标头,而我在脚本中排除了标头的原因):
Filename;VideoDing_Timecode;Video_R4Start;Video_R4End;Video_R24Start;Video_R24End;Video_R0plus15
log1_front.MTS;04:44.0;09:37.1;11:37.1;28:00.3;30:00.3;19:44.0
log2_front.MTS;03:50.0;08:11.2;10:11.2;19:44.9;21:44.9;18:50.0
log3_front.MTS;04:10.1;08:32.4;10:32.4;16:49.2;18:49.2;19:10.1
log5_front.MTS;01:14.7;04:50.2;06:50.2;14:24.5;16:24.5;16:14.7

以下是CMD中的完整输出:

答案 0 :(得分:0)
显然,当我直接输入命令时,需要使用双引号。但是,当我使用Python时,我需要删除这些双引号。不知道为什么会这样,但是对于想要剪切视频的任何人,以供将来参考,下面是正确的代码:
