I'm trying to update substudy and get it running again after a long time not using it. It used to work! On this same laptop, even, but before I'd upgraded to El Capitan.

I'm on a Mac (El Capitan 10.11.5). I ran multirust update stable and brew install cmake ffmpeg to make sure those dependencies were all up to date. No issues there.

But whether I run cargo install substudy or cargo build, I get the same error message:

/Users/arthaey/.multirust/toolchains/stable/cargo/registry/src/github.com-1ecc6299db9ec823/substudy-0.4.0/src/video.rs:13:20: 13:25 warning: unused import, #[warn(unused_imports)] on by default

Running with --verbose didn't give any more useful output.

Also, if a non-exe file maching binary is present in the build directory, it'll get picked up but there'll be an error saying that this binary is not a valid Win32 binary.

Solution: adjust tests to accommodate for Windows' ecosystem and make the binary name automatically assume .exe extension when compiled on Windows.

When I run, substudy combine episode_01_01.es.srt episode_01_01.en.srt > episode_01_01.bilingual.srt

Nothing happens. If I drop the word substudy from the above, I get "Usage: combine Filel OP file2" as an error.

If I run substudy export csv episode_01_01.mkv episode_01_01.es.srt episode_01_01.en.srt then I get "MissingFieldError("streams")"

If I run that code wthout the ">" after mkv, then I get: Invalid arguments. Usage: substudy clean <subs> substudy combine <foreign-subs> <native-subs> substudy export csv <video> <foreign-subs> [<native-subs>] substudy export review <video> <foreign-subs> [<native-subs>] substudy export tracks <video> <foreign-subs> substudy list tracks <video> substudy --help substudy --version

https://forum.language-learners.org/viewtopic.php?f=19&t=6360&start=10 is where another person tried to help. I welcome your thoughts on where I am going wrong. I installed LinuxMint18 just to use your program, so maybe it is possible I am missing some foundational download I need before using substudy.

I'm trying to export my mkv to csv using the given command substudy export csv episode_07_01.mkv \ episode_07_01.fr.srt episode_07_01.en.srt but I can't seem to get it working. I get ExpectedError("Number", "-99").

I'm having no problems using the combine code for the bilingual subtitles. I just can't seem to get the export working for the life of me..

The default algorithm for splitting up audio works well enough for TV shows, where splitting up a sentence isn't really the end of the world.

For my weaker languages, I had the idea to use substudy with songs instead of TV. But it's going to be really weird and annoying to split up lyrics that way, especially when they're already "bite-sized".

So here I am, asking for yet another option to be added to substudy. ;)

Great tool, thank you for your efforts.

I do wish for one feature especially though, it's almost a deal-breaker, and that's the ability to adjust the padding of subtitle times through an argument when generating Anki cards through substudy.

It seems to me, and correct me if I'm wrong, but it certainly seems that the times are being automatically padded by substudy, meaning there is extra time added on both the start and the end.

This might be a sensible default, as it's presumably better to have a little too much of what's said, than too little, but I have some pretty nicely timed subtitles, and it would be great to be able to prevent this padding from taking place, even if it's not the default.

I've tried looking through the source, but tbh, I'm not a great programmer, I'm actually integrating substudy into some scripts, but I've been looking at a lot of python and POSIX sh for the last few years, not so much C-like languages, and I'm totally unfamiliar with Rust. It seems a lot isn't commented, so I find my eyes glazing over and my brain shutting down when I tried to figure stuff out in the source myself.

Even if this isn't what's happening, perhaps a command line argument to reduce or increase padding would be good.

I'd try to implement it myself as I'm sure it's rather simple, but for the reasons I stated earlier, I'm pretty much at the mercy of your (or some other kind soul's) benevolence.

The automatic splitting seems pretty decent, but sometimes it chops a sentence awkwardly. It would be nice if I could ask substudy to include one line of dialog before or after the "target" line for context.

Ideally, as separate "columns" in the csv output, so I can style them differently in Anki. :)

An odd error.

Cannot truncate time period Period { begin: 610.839, end: 611.874 } at 610.839

The first part of the file is.

1 00:00:06,120 --> 00:00:08,475 Parco nazionale Harwood PENNSYLVANIA

2 00:00:08,519 --> 00:00:09,998 Forse dovremmo tornare indietro.

I've compared this to other ones which have been successful and it doesn't look any different. So, is it possible the problem is with the mpv file output by ogmrip ?

Using the list track command produces an error when querying a mkv file created by ogmrip. Had to use ogmrip because of copy protection.

substudy list tracks CM6-0E-UT3.2_DES.mkv MissingFieldError("tags")

Using the command mkvinfo, I can see the track information and extract the appropriate sub-title track.

mkvinfo CM6-0E-UT3.2_DES.mkv | + A track | + Track number: 4 (track ID for mkvmerge & mkvextract: 3) | + Track UID: 914786270282254080 | + Track type: subtitles | + Lacing flag: 0 | + Codec ID: S_TEXT/UTF8 | + A track | + Track number: 5 (track ID for mkvmerge & mkvextract: 4) | + Track UID: 9054752488569948265 | + Track type: subtitles | + Default flag: 0 | + Lacing flag: 0 | + Codec ID: S_TEXT/UTF8 | + Language: ita

any subsequent reference to tracks however fails on the tags metadata.

substudy export tracks CM6-0E-UT3.2_DES.mkv it.srt MissingFieldError("tags")

Seems if you use a format (mp4) other then MKV you get this error "MissingFieldError("codec_name")". However a simple convert works in ffmpeg. I wasn't sure if there is another way to get around this. I may try my hand at a PR on this, but have never done Rust ;) Great program btw, much easier then sub2srs

ffmpeg -i ~/Downloads/file.mp4 -vcodec copy -acodec copy ~/Downloads/out_file.mkv

It would be nice to have graphic interface sometime in the future, although I know there is no clear solution to this problem now, so maybe just keep this issue open until there is a light, cross-platform solution in the future.

The tool is great but the images are a little small for me. I guess defaulting to small images is to save on disk space but it would be great to able to select image size. I'm not so familiar with Rust so I couldn't figure out from the code how image size is handled currently, but perhaps allowing the user to scale the input resolution by a factor of the original would be the simplest way.

Adds cleaning of bracketed text such as [Music] to the substudy clean command. This text is found on YouTube video subtitles such as the start of this video. Let me know if you want me to remove the test case I added to substudy/src/clean.rs or if there is a better place to put it. Thanks for making this project!

First of all thanks for the amazing tool. It's super nice to be able to combine both subtitles.

Ideally I would like to be able to select words from a subtitlte and act on them like https://animelon.com/video/594e558522477e0e27f1f035 does

I think you have a similar project with https://github.com/emk/subtitles-rs/issues/22 . A more short term goal could be, in the srt file, to map each words to their translation (in combined mode) via different colors /underline where that makes sense.

In a framework such as GStreamer, the vobsub decoder will be inserted in a pipeline after elements taking care of demuxing the Mpeg 2 stream. In such a situation, the PES packets are already parsed. Only the subtitle data is available.

This PR introduces the data mode in SubtitlesFromChunks which uses the same interface as the packet mode. The file fixtures/example_data.sub is a demuxed version of fixtures/example.sub.

Notes:

• I didn't try fuzz testing yet.
• This PR includes the changes from #41. I'll rebase if it is accepted.

This is a first step toward https://github.com/sdroege/gst-plugin-rs/issues/21

The PR adds a new struct SubtitlesFromChunks which keeps track of the parsing context and allows passing chunks.

Except if I missed something, the API and behaviour for Subtitles is unchanged. I couldn't find a solution to avoid using the Rc<RefCell<>> for SubtitlesContext without breaking the existing API.

Changes were tested using examples in "fixtures" (including for the parse_corpus ignored set).
