Some books of the Bible are producing errors:

thread 'main' panicked at 'The prefix pattern was not found.', src/ffwrappers/probe.rs:246:21
note: run with `RUST_BACKTRACE=1` environment variable to display a backtrace

The reason for this crash is due to the Psalms videos not having a title tag.

        {
            "id": 2,
            "time_base": "1/1000",
            "start": 40007,
            "start_time": "40.007000",
            "end": 79413,
            "end_time": "79.413000",
            "tags": {
                "title": ""
            }

Some books of the Bible don't include all verses. I suspect that the program will crash when using the -a flag with these books. Need to test it.

• Find a book with a missing verse
• Test it with the -a flag.

Detect if ffprobe and ffmpeg are installed and if they are not, exit with a message to the user to install ffprobe and ffmpeg,

Issue #17 is still being displayed with help, scriptx -h. Remove it since the bug was resolved.

Discovered that the book of Deuteronomy does not cut properly. Was trying to cut Deuteronomy 7:4 when I discovered the problem.

Update: Problem occurs with Exodus as well.

I also cut 1 Corinthians chapter 6 and 7 without an issue.

Problem

The video produced remains black and only shows the scripture towards the end in slow motion and choppy. Currently, Deuteronomy 7 is the only book I have run into that this happens, There may be more.

Notes

While using ScriptX v0.3.2, should affect all versions <= v0.3.2.

For Research

Codec: H.264

The H.264 codec isn't a single codec, there are various profiles, for example, there are to mention three:

• H.264 (Baseline)
• H.264 (Main)
• H.264 (High)

These profiles produces video files with the same quality but uses less bandwidth when streaming.1, 2, 3 The video codec used with Deuteronomy is H.264 (High) while the codec used in 1 Corinthians chapter 6 and 7 is H.264 (Baseline). The book of Genesis uses H.264 (Constrained Baseline Profile) -- note, the book of Genesis cuts fine.

If the file's H.264 profile is causing the problem, then a possible solution is to pass the profile to ffmpeg when processing.4 As an example:

ffmpeg -i input.mp4 -c:v libx264 -profile:v high -level:v 4.0 -c:a copy output.mp4

Matadata regarding codec used in Exodus:

    Stream #0:0(eng): Data: bin_data (tx3g / 0x67337874), 0 kb/s
    Metadata:
      creation_time   : 2014-02-28T21:41:42.000000Z
      handler_name    : Apple Text Media Handler
    Stream #0:1(eng): Video: h264 (High) (avc1 / 0x31637661), yuv420p(tv, bt709), 1280x720, 1563 kb/s, 29.97 fps, 29.97 tbr, 2997 tbn, 5994 tbc (default)
    Metadata:
      creation_time   : 2014-02-28T21:41:42.000000Z
      handler_name    : Apple Video Media Handler
    Stream #0:2: Video: mjpeg (Baseline), yuvj420p(pc, bt470bg/unknown/unknown), 288x288, 90k tbr, 90k tbn, 90k tbc (attached pic)

Todo

• Find another video that uses H.264 (High) and see if the problem occurs. [edit: problem occurs with the book of Exedus as well which uses - H.264 (High)]
  • If so, try passing the profile to ffmpeg.

Remove the time stamp debugging output to terminal and replace it with a progress bar instead. Especially helpful when the -a flag is used for extracting all scriptures from the file.

Consider using indicatif.

Reword from cut to extract

Use std::path when dealing with paths and files.

The README.md file is constantly falling out of sync with the usage section. Script a solution.

When the user uses the -o flag, they have to add a video container extension otherwise the program crashes without any indication of what went wrong.

Example

$ scriptx -f nwt_01_Ge_ASL_10_r480P.m4v -v 20 -o Gen10-20
thread 'main' panicked at 'ffmpeg's exit status was FAILURE', /home/joel/.cargo/registry/src/github.com-1ecc6299db9ec823/scriptx-0.2.1/src/ff.rs:191:13
note: run with `RUST_BACKTRACE=1` environment variable to display a backtrace

Solution

1. If the user doesn't add an extension, add one by default
2. Improve error handling to be more informative

The description in Cargo.toml has an error that needs to be fixed. The string should be a short description of the application.

The project needs to have tests, especially the library.

A dependency being used by scriptx is using ansi_term which has been deprecated.

Update dependencies to fix issue.

https://rustsec.org

Add ability to cut all verses in a chapter.

Project is not a library so the docs don't build.

Also, look for option to have doc.rs not build my docs.

Not all videos have the correct meta data causing the program to crash. Improve the error handling for better user experience.

See issue #30.

scriptx --help still displays a general short description. Replace it with: ScriptX cuts verses from the American Sign Language version of the New World Translation Bible.

When the user uses -o with a path, the program crashes.

When scriptures are cut, the first few seconds are missing.

Create an 'Action' to build a deb package.

ScriptX crashes when it tries to output a file that already exists.

Fix

• handling of outputting of a file that already exists. Better error reporting for example.
• fine a solution to three problem. The error Comes from ffmpeg, perhaps there's a flag that can be used to override existing files.

Mention the problems one might run into while working with some books of the Bible.

See issue #30 as an example.

Add option to delete original file when cut is done.

Romans 10:10 was returned as unfound.

Set up a PPA so Ubuntu users can download the latest version without having to use cargo install.

ScriptX should be able to automatically detect the book and chapter of the video in order to avoid the user from having to type it in, for example, `-v "joel 1:1".

Instead the user should just have to type `-v 1" and program fills in the book name and chapter number when searching title tags.

Remove ffmpeg tag from Cargo.toml.

Make needed change to the clap code to be able to migrate to clap 3. The current version of clap being used is 2.33.4.

Currently have a mess of methods chained together passing values around and it's only going to get worse.

Consider fixing it with additional structs to deal with time stamps and any other thing needed to carry out its function.

The Cargo.toml mentions verses instead of scripture. Make changes.

Implement the ability to cut ranges of scriptures. For example, -v 3-5.

Implement the ability to call for a range to be cut. For example, -v 4-6 would cut verses 4 though 6.
