SplitFilter 不好用

[NaichuanYang]

Hi~~
发现splitfilter 不好用，但是同样的方式在 ffmpeg-python下可用
环境 ：python3.9

input_v =  ffmpeg.input(src).video
split_v = input_v.split()
split_v[0].output(...).run()

  File "/usr/local/lib/python3.9/site-packages/ffmpeg/nodes.py", line 152, in run
    process = self.run_async(
  File "/usr/local/lib/python3.9/site-packages/ffmpeg/nodes.py", line 128, in run_async
    cmd_args_seq = self.compile(
  File "/usr/local/lib/python3.9/site-packages/ffmpeg/nodes.py", line 108, in compile
    cmd_args_seq = [executable] + self.get_output_args(overwrite, progress)
  File "/usr/local/lib/python3.9/site-packages/ffmpeg/nodes.py", line 84, in get_output_args
    filters_spec = get_filters_spec(type_nodes[NodeTypes.Filter],
  File "/usr/local/lib/python3.9/site-packages/ffmpeg/_node.py", line 271, in get_filters_spec
    return ';'.join(
  File "/usr/local/lib/python3.9/site-packages/ffmpeg/_node.py", line 272, in <genexpr>
    get_filter_spec(node, outgoing_edge_graphs[node], stream_tag_graph)
  File "/usr/local/lib/python3.9/site-packages/ffmpeg/_node.py", line 248, in get_filter_spec
    return f"{''.join(inputs)}{node.get_filter_spec(outgoing_edges)}{''.join(outputs)}"
  File "/usr/local/lib/python3.9/site-packages/ffmpeg/nodes.py", line 2221, in get_filter_spec
    params = escape(self.Label, '\\\'=:') + '=' + ':'.join(args)
TypeError: sequence item 0: expected str instance, int found

好的，我看到了，已经修复这个问题。你可以安装最新版：

pip install -U ffmpeg-generator -i https://pypi.org/simple/
