[FR] Support multiple input files and split options

[F-park]

Future Request Reason

Currently, the script just calls self._set_file_info() once, so we can only get one input file durations.

By the way, ffmpeg support spilt file by these options, we should support -ss, -t and -to, it is common to use.

Solution

I will work in #17

We can try to support multiple input files, but remember that the progress bar uses the duration of the input file to calculate the percentage progress. If there are multiple input files with different durations, you will need to make sure that the correct duration is set as the total when creating the progress bar.

I would say in most use cases the transcoding length is the duration of the shorter file, so this would be a good default to set when setting the total for the progress bar, but if you can think of any situations where the transcoding length will be equal to the length of the larger file, add logic to set the total to the length of the longer file in these situations.

If -t is in the FFmpeg command , this is simple as the total value for the progress bar should be set to the value after -t.

Thanks for your suggestion. BTW, there is a new situation when ffmpeg -f concat -i filelist.txt -c copy output.mkv

• filelist.txt:

file 'input1.mkv'
file 'input2.mkv'
file 'input3.mkv'

I consider I should learn how to use shlex, we should write a simple lexical analysis for ffmpeg
