vsrawsource - Raw Video Reader for VapourSynth

[Chikuzen]

I wrote a VapourSynth plugin named vsrawsource.
vsrawsource-0.3.2.zip

source code repository
https://github.com/chikuzen/vsrawsource

This plugin is the rewrited version of avisynth's rawsource.dll to for VS from scratch.

I am inviting the patch for MacOS X build now.

EDIT:
2013/07/31
updated to 0.3.2

cool! thank you Chikuzen
i compiled it successfully on linux, but why does the configure script will work only when i run it as root? (sudo sh configure)

because I forgot to 'chmod +x' to configure

Which formats are supported?

To query the list of formats:

supported color formats:
see core.raws.FormatList()

[Chikuzen]

or see source code.

Thanks-all clear now

I looked at the source. It's a bad idea to write to stdout directly. If you want to return text you really should return it as a string value from the function because as it is it won't even interact with the python interpreter nicely.
My personal opinion is that this kind of stuff belongs in the documentation but that's up to you.

[Chikuzen]

Update to 0.2.0

* new option 'rowbytes_align'.
* support Windows Bitmap(.bmp)

BMP support is only for 24bit/32bit uncompressed RGB (palette,RLE and the others are not supported).

OS X compiled version can be grabbed from here.

Just a quick note, it seems that your function registration is looking for parameters named "header_off" and "frame_off":

...

VS_EXTERNAL_API(void) VapourSynthPluginInit(
    VSConfigPlugin f_config, VSRegisterFunction f_register, VSPlugin *plugin)
{
    f_config("chikuzen.does.not.have.his.own.domain.raws", "raws",
             "Raw-format file Reader for VapourSynth " VS_RAWS_VERSION,
             VAPOURSYNTH_API_VERSION, 1, plugin);
    f_register("Source", "source:data;width:int:opt;height:int:opt;"
               "fpsnum:int:opt;fpsden:int:opt;src_fmt:data:opt;"
               "header_off:int:opt;frame_off:int:opt;rowbytes_align:int:opt",
               create_source, NULL, plugin);
}

Whereas the readme, and your argument setting code, use "off_header" and "off_frame":

...

vs_args_t va = { in, out, core, vsapi };

    if (header > 0) {
        set_args_int(&rh->vi.width, 720, "width", &va);
        set_args_int(&rh->vi.height, 480, "height", &va);
        set_args_int(&rh->off_header, 0, "off_header", &va);
        set_args_int(&rh->off_frame, 0, "off_frame", &va);
        set_args_int(&rh->row_adjust, 1, "rowbytes_align", &va);
        set_args_data(rh->src_format, "I420", "src_fmt", FORMAT_MAX_LEN, &va);
    }

...

In my quest to get my hands on planar RGB input to test my own plugin, I found the need to use those options, but they don't seem to work as expected, and it looks like it's just a mixup of the names.

[Chikuzen]

oops, sorry.
I didn't notice that typo.

It seems that VS-r15 is coming soon and API version is bumped up.
so i'll release new version with fixed it as soon as r15 is come.

[Robert Martens]

That's great, thank you! I'm in no rush, mind you, I just wanted to make sure I mentioned it. In the meantime, I've written a little command line application that strips out the headers of the files I'm working with, so I can work around it for as long as I need to. I appreciate your work on this plugin, it's proving to be very useful!

[Chikuzen]

updated to 0.3.0

* Alpha channel support
* fix typo

All alpha channel data will be stored in "_Alpha" prop.
You can extract it with 'alpha = core.std.PropToClip(clip)' as a Gray clip.

[Chikuzen]

updated to 0.3.1

* change alpha support method.

[Chikuzen]

update to 0.3.2

* fix memory leak
* cope with the filename which includes non-ASCII characters

[Myrsloik]

New compiles for 64 bit are available here.

how do I compile this thing exactly?
I followed the instructions

$ cd ./vsrawsource
$ ./configure
$ make

and everything went okay actually, no error occurred, I got a 22kb .dll file
and I copied that file along with cygwin1.dll to the plugin directory and tried to run it
and vaporsynth just crashed without any warning

Maybe your changes are incorrect and that's why it crashed. (If you're not making any changes, just use the existing DLLs.) Since you have Cygwin, you can probably install gdb and find out more about the crash.

There are no secret compilation instructions that make it not crash. Probably.

[feisty2]

I don't know, after failed to run that modified version, I tried to compile Chikuzen's original code, and it still crashed
I'll get gdb and report back soon
