This is what this patch series attempts to do. I agree this is a better way forward than depending on the system header. I skimmed through the series and it looks good but I have a few thoughts 1) format names: now that we have our own formats, how should they be named? This version uses the DRM defined format names, and it makes sense indeed to make it easier for people using a DRM sink to have a libcamera format. Howeverm, afair, gstreamer in example uses fourcc names from fourcc.org, which I have no idea if it's authoritative or not. Any opinion on that ? 2) I suspect the v4l2->libcamera->drm dance on pixel format definitions we have on-going for RAW formats will repeat itself once we add more platforms. This does not change the current situation where new platform with a new V4L2 fourcc code -> we define a format in libcamera associated with a temporary DRM fourcc code -> We upstream the DRM fourcc code -> upstream happens <- We have to change the format definition in libcamera, which is not an issue now, but once things are more stable it could be I wonder if instead of exposing PixelFormats (which are created using a DRM fourcc which might not be stable) we should not expose an enumeration of fourcc-independent codes, and have a run-time translation to the drm fourcc ones.. If I look at const std::map<PixelFormat, PixelFormatInfo> pixelFormatInfo{ /* RGB formats. */ { formats::BGR888, { .format = formats::BGR888, .v4l2Format = V4L2PixelFormat(V4L2_PIX_FMT_RGB24), .bitsPerPixel = 24, .colourEncoding = PixelFormatInfo::ColourEncodingRGB, .packed = false, } }, The map keys and the first field of the PixelFormatInfo are actually the same thing.. I know this means defining our own format codes (which might very well be a sequential enumeration), requires run-time translations, and kind of defeat using DRM fourcc (or any kind of existing fourcc codes set). But what happens here basically does that already, applications gets provided a set of identifiers, it does just only partially matters that they're consutrcted using DRM fourccs behing the curatins, as I expect applications using DRM to have to look at the header and then realize that they can PixelFormat(DRM_FORMAT_xyz) instead of having to look at what libcamera::formats::xys actually is...

I don't think there's any authoritative list of pixel format names (otherwise we would have an authoritative list of 4CC values too, and we wouldn't need to deal with this mess :-)). As we use the same numerical values as DRM, I think it makes sense to use similar names. I've written "similar" and not "identical" on purpose, as DRM has names for 4CCs and for modifiers, but not for pixel formats, so we'll need to create our own names for modified formats (SGRBG10_CSI2P is an example of such a name introduced in this series). > 2) I suspect the v4l2->libcamera->drm dance on pixel format > definitions we have on-going for RAW formats will repeat itself once > we add more platforms.

I'd personally frown upon yet another set of pixel formats with yet another translation. We have too many of them already. I'm open to alternatives, but only if the alternative make things simpler, not more complicated :-) As for you concern above, once we start caring about stability, we'll need to have kernel drivers merged before merging the corresponding code in libcamera, regardless of whether we use DRM pixel formats or our own pixel formats anyway. I'd be willing to consider another set of pixel format values if they were used by a relevant kernel API and were pushed as the new standard. > > Patches 01/11 to 04/11 are preparatory cleanups, please see individual > > patches for details.

GStreamer uses a mix of Microsoft defined fourcc, Apple define fourcc and fourcc.org. This has to do with fourcc found in ISOMP4, Matroska and other containers (even though you cannot assume consistencies, and there is even few duplicates coming from errors in major software). The rest is very custom, we never managed to actually found a working rules. Newer formats like I422_10BE, NV12_64Z32, NV12_10LE32 capture more information but pretty much all fails in one way to capture everything a really be consistent.
