flac and exiftool? #4863

Closed m95341175 closed 3 years ago

m95341175 commented 3 years ago

Hello,

Has anyone considered building flac or exiftool? I would find those very handy if they were available. Thanks!

Mike

Flac (Free Lossless Audio Codec) is a codec not a tool.

m95341175 commented 3 years ago

Hi,

I'm gonna disagree with you on that point. If you look here (below), you'll see that there are two command line tools, flac and metaflac. Those are the ones I'm asking about. BTW, I would not have asked if I didn't know what I was talking about. https://xiph.org/flac/download.html

Thanks, Mike

For package request we have a template that we ask everyone fill out, this avoids such a confusion. Regarding Flac, There is already a ffmpeg package that should be able to do anything flac can do.

Thanks. I'm not sure about the ffmpeg/flac equivalence. I suspect that for my purposes, ffmpeg is not the right tool. In any case, to comply:

Name: flac Description: the codec and the two command line applications flac and metaflac Website: https://xiph.org/flac/ Software documentation: https://xiph.org/flac/documentation.html Build/installation documentation: [in source tarball] Source code: https://ftp.osuosl.org/pub/xiph/releases/flac/ License: https://xiph.org/flac/license.html

Name: ExifTool Description: metadata tool Website: https://exiftool.org/ Software documentation: https://exiftool.org/#running Build/installation documentation: https://exiftool.org/install.html Source code: https://exiftool.org/Image-ExifTool-12.30.tar.gz License: https://exiftool.org/ ("License", 3rd from bottom of page)

I'd still like to get both of these in package form if possible. I'm hesitant to build them directly on my Synology since I have a feeling that they'll be gone after the next update.

Thanks, Mike

Flac is a codec and not an application, you want flac tools instead. But all functionality of both flac tools and ExifTool are covered by ffmpeg, so no reason add those application.

m95341175 commented 3 years ago

Okay. Well, you're just plain wrong on the second thing. Neither is covered fully by ffmpeg. If you don't want to do it yourself or would seek to prevent others from creating packages for [the] flac [tools] and exiftool then fine. But don't try to tell me that you know what you're talking about WRT what these do. There's one in every crowd, I suppose.

Hi @m95341175 , please adjust your tone as replies as such are not acceptable. Please be mindful that we are a group of volunteer developers doing our best to package free software onto Synology NAS.

As for flac, it is package and part of current ffmpeg: /var/packages/ffmpeg/target/bin/flac You can use it either through ffmpeg or directly through the command line utility.

As for exiftool, it is not currently packaged but feel free to provide code so we can create a package with or add to existing. Also note that ffmpeg does allow playing with metadata to some degree so you may be able to make some mileage there?

Hope this help, cheers.

m95341175 commented 3 years ago

Hi @th0ma7 , I apologize for any intemperate tone but I think being told things that I know aren't so was probably the first intemperate provocation. In any case, I really appreciate your reply as I didn't realize that flac and metaflac were packaged with ffmpeg. I did a search of the package description and didn't see them. Now I do see them on my system but they aren't in my path. Would it be reasonable for me to create symbolic links for them in /usr/local/bin or is that "owned" by the OS and package manager on this distro in such a way that doing so would be considered a problem?

Next, as to exiftool, when you say "provide code" are you talking about the things I provided above namely a link to the tarball or are you talking about me trying to do this myself? If someone had the wherewithal to add exiftool to an existing package, I would really appreciate it. If you look at what it does for 1 or 2 minutes I think you'll see that it's metadata capabilities go WAY beyond what's included in ffmpeg and some of those are what I'm after. Please advise.

And, again, thanks for your comments. I really appreciate the fact that folks take the time to develop and maintain these packages.

th0ma7 commented 3 years ago

if you are interested and have a bit of development skilset you can provide code to create a cross/exiftool that compiles on all archs the submit a github pull request (PR). In the repository there are tons of examples and we have wiki providing howtos.

If not, well I may (or someone else in the team) have a look at it eventually. Perhaps adding it to the ffmpeg package could somewhat make sense as it already provide all other media type toolset or creating a do-it-yourself package option so user can build them as standalone.

th0ma7 commented 3 years ago

@m95341175 I went on and read a bit on ExifTool and this is a no go. You might be able to install it within your user environment on your local DSM by installing Synology's perl package and invoking CPAN to install it as a module.

By experience sadly many perl cpan modules (or their dependencies) also require a platform compatible local gcc compiler to build source code and link it to perl libraries which is something that can't be achieved easily. Perl doesn't cross-compile (e.g. I cannot build a perl package with CPAN source modules dependencies for another CPU type than the one I am building from, at least not natively and not without heavy changes and a lot of luck, been there, done that).

So all in all, you do have flac through ffmpeg package. As for ExifTool I whish you good luck.

Note that if you do find an equivalent for python it may be much easier to achieve your goal. But using perl is not an technical option.

m95341175 commented 3 years ago

Thanks @th0ma7 , I really appreciate you looking into this. I will make do with flac and metaflac and just run exiftool over my network rather than on-box. Cheers!

@m95341175 I have no problem running exiftool on my DS-115j (armada370) I downloaded and extracted Image-ExifTool-12.30.tar.gz (and installed the synology perl package).

Thanks @hgy59 I'll give it a try.

What is the status of ExifTool? What makes it not possible to package?

th0ma7 commented 3 years ago

Repackaging from someone else's package isn't something we normally do and will not provide much added value. I would advocate that our time is better spent on completing migrations of other packages to DSM7 instead.

I suggest you simply download the tar.gz file online and it should in theory work out of the box. Just follow the howto here: https://exiftool.org/install.html#Unix
