Fix raw formats

[xiaozhuai]

Description

directshow claims that the color format supported is MEDIASUBTYPE_RGB24, and it should correspond to VideoFormat::RGB24 instead of VideoFormat::XRGB

Motivation and Context

This change is completely self-explanatory

How Has This Been Tested?

I have wrote the following test code and tested multiple camera devices that support RGB24 format on Windows 10, and now it can provide the correct format.

#include <ole2.h>
#include <cstdio>
#include "dshowcapture.hpp"

const char *format2str(DShow::VideoFormat format) {
    switch (format) {
        case DShow::VideoFormat::Any:
            return "Any";
        default:
        case DShow::VideoFormat::Unknown:
            return "Unknown";
        case DShow::VideoFormat::ARGB:
            return "ARGB";
        case DShow::VideoFormat::XRGB:
            return "XRGB";
        case DShow::VideoFormat::RGB24:
            return "RGB";
        case DShow::VideoFormat::I420:
            return "I420";
        case DShow::VideoFormat::NV12:
            return "NV12";
        case DShow::VideoFormat::YV12:
            return "YV12";
        case DShow::VideoFormat::Y800:
            return "Y800";
        case DShow::VideoFormat::YVYU:
            return "YVYU";
        case DShow::VideoFormat::YUY2:
            return "YUY2";
        case DShow::VideoFormat::UYVY:
            return "UYVY";
        case DShow::VideoFormat::HDYC:
            return "HDYC";
        case DShow::VideoFormat::MJPEG:
            return "MJPEG";
        case DShow::VideoFormat::H264:
            return "H264";
    }
}

int main() {
    CoInitialize(nullptr);

    std::vector<DShow::VideoDevice> devices;
    if (!DShow::Device::EnumVideoDevices(devices)) {
        printf("ERROR! Unable to list video devices\n");
        return -1;
    }

    if (devices.empty()) {
        printf("ERROR! No video devices found\n");
        return -1;
    }

    printf("Devices:\n");
    for (int i = 0; i < devices.size(); i++) {
        const auto &device = devices[i];
        printf("----------------------------------\n");
        printf("- Device %d:\n", i);
        wprintf(L"  - Device: %s\n", device.name.c_str());
        wprintf(L"  - Path: %s\n", device.path.c_str());
        printf("  - Caps:\n");
        for (const auto &cap : device.caps) {
            printf("    - %dx%d %s\n", cap.minCX, cap.minCY, format2str(cap.format));
        }
    }

    return 0;
}

libdshowcapture/source/dshow-formats.cpp

Lines 295 to 296 in 8878638

	else if (mt.subtype == MEDIASUBTYPE_IYUV)
	format = VideoFormat::I420;

also looks like it might be a copy pasto. (I have no idea what this code does, I'm just looking for the pattern that the format 'kind' seems to usually match elsewhere in this file)

@Fenrirthviti Can you clarify what you mean by PR template?
@xiaozhuai Can you try to follow the PR template?

[Fenrirthviti]

I'm not sure what needs clarifying. Our repo requires all PRs to use our PR template, provided as part of the GitHub repo config. I'm baffled how this was even submitted without using one, as it's required to submit a PR to us. It was either using some third-party client that bypasses this repo setting, or the user explicitly looked at the template and chose to delete it.

@BillyONeal @Fenrirthviti Ok guys, I've filled out the PR template.

I was looking for a .github/pull_request_template.md but didn't find one 😅
