Is it possible to add the function of playing subtitle in the terminal?

that is, the function of subtitle player.

I'm not sure what you're asking. What would "playing" mean here?

Edenharder commented

@cdown printing the content of the subtitle in the terminal (or somewhere) at the corresponding time of the subtitle.

I think the new srt play utility I just added should do basically what you want: 1de5f02

Could you kindly give an example how to use this utility with an existing .srt file? That is, an example like

import srt

test = open("test.srt")
srt.play(test)
cdown commented

After installing using setup.py or pip, srt play -i test.srt should work. If the srt file is not in your default system encoding, you may need to use the -e flag to set the encoding, by doing something like srt play -e gb2312 -i test.srt, where gb2312 is the source encoding.

srt play -i test.srt gives an error that

... srt_tools/utils.py", line 119, in set_basic_args with open(stream, encoding=args.encoding) as input_f:
TypeError: 'encoding' is an invalid keyword argument for this function

Hm, it works in Python 3, but not in Python 2. When I fix issue #28, that shouldn't happen any more :-)

The reason is because we use the new open() API in utils which is not compatible with Python 2. Let me go fix that.

You can try with the latest changes on develop. It works for me with Python 2:

% srt play -i ~/Downloads/test.srt -e gb2312

Here is my test file (I have renamed it to test.txt to upload, the original name is test.srt)
test.txt

The error says that

srt.py", line 325, in _raise_if_not_contiguous
    raise SRTParseError(expected_start, actual_start, unmatched_content)
srt.SRTParseError: Expected contiguous start of match or end of input at char 0, but started at char 1 (unmatched content: u'\ufeff')

Your file is encoded as utf-8-sig, not utf-8, so you need to explicitly specify this:

% srt play -i /tmp/test.txt -e utf-8-sig

Thanks! It works! One more question, how to find the encoding of the file?

Edenharder commented

And I think it will be not difficult to add the beginning time as args to the function play. That is,

srt play -i [args:beginning time] /tmp/test.txt -e utf-8-sig

will print from the first content of the subtitle whose time is after [args:beginning time].

I try to adhere to the Unix philosophy when designing my tools -- ie. one tool should do one thing, and one thing only. To that effect, you want to use fixed-timeshift like so (you need to use an intermediate file because stdin and stdout cannot have their encoding changed in a reasonable way, although it's possible to soak to an intermediate file transparently, see #33):

srt fixed-timeshift -i /tmp/test.txt --seconds -60 -e utf-8-sig -o /tmp/test2.txt
srt play -i /tmp/test2.txt -e utf-8-sig
