v1.3 can't open certain file on Intel Mac Pro

[AfflatusX]

Is there an existing issue for this?

• I have searched the existing issues

Have you tried the latest build?

• I have tried the latest build

Gyroflow version

v1.3 (dev and prod)

What operating system are you using?

macOS Monterey

What GPU are you using?

AMD Radeon Pro 580X

What happened?

When trying to load video files with YUV422 10bit HEVC format, Gyroflow just shows the spinner forever without loading the video.

I noticed this is only happening on Intel Mac Pro (Xeon W + 580X Pro), but not happening on my M2 Macbook Air. Unfortunately Air's GPU doesn't seem to support the export encoding.

Is it an known issue that this format is not supported?

Btw I think it might have something todo with gamma / color profile, the footage was shot using Sony a7s iii, Gamma S-Log3, Color Mode: S-Gamut3.Cine.

I tried to use a different file without the color profile and it seems to work on both intel and M1 mac.

You can use the sample video I uploaded to Dropbox in the issue description to test it out.

[AdrianEddy]

I can't reproduce it on Windows or on M2 Air, and I don't have Intel Mac to test.
On your Intel mac, after the video fails to load, close gyroflow, go to "Show package contents -> Contents -> MacOS" and upload gyroflow.log file from there.

Also, what exactly do you mean by Unfortunately Air's GPU doesn't seem to support the export encoding.?
M2 has a dedicated hardware media engine and supports way more accelerated exporting formats than Intel+AMD.

@AdrianEddy appreciate the quick reply! Indeed windows and M2 Air works fine on my end as well.

gyroflow.log

log attached.

So the footage was shot with S-log3 - in order to preserve the light/color information, I either do a color grading before export, stablize it, then export to other format (that's what I do with Sony Catalyst Browse), or, run gyroflow and export in the same format so that I can post process it in Premiere.

With Gyroflow v1.3, when I click export, it tells me exporting as original format isn't supported (see screenshot below). I tried the other format it suggested but they mostly lose all the pixel information (because S-LOG3 is over exposed without LUT applied).

That's the reason I need to use the mac pro to do the export - since it has 32 cores on CPU.

@wang-bin looks like the pixel format is not supported, can it be added or can we do a fallback in this case?

yes. the format is almost the same as m1/2, except color range is different. i will fix it today.

@AdrianEddy try the last build

[AdrianEddy]

@AfflatusX please try latest dev build https://gyroflow.xyz/devbuild/?autodownload and post gyroflow.log if it's still not working

[AfflatusX]

yup can confirm it's working now! Thanks for the fix!

[AfflatusX]

actually before I close - @AdrianEddy / @wang-bin seems like neither 580X, Apple M2, or 3080Ti supports YUV422P10LE format for encoding.

I'm wondering is that a HW issue or a SW issue?

[AdrianEddy]

YUV formats are not really supported by apple, they are coming from software decoders. Make sure to check Use GPU decoding under Advanced (or uncheck and re-check it), then it should use P210LE, which is equivalent to YUV422P10LE
P010LE is equivalent to YUV420P10LE

[AfflatusX]

Cool thanks for the answer!

[AfflatusX]

@AdrianEddy Tried to re-toggle the option, but It doesn't look like P210LE was given as an alternative px format - see log:
gyroflow.log

I noticed these two lines:

01:19:06 [DEBUG] (1) gyroflow::rendering: Possible encoders with Amd: [("hevc_videotoolbox", true), ("libx265", false)]

and

01:19:06 [DEBUG] (2) gyroflow::rendering::ffmpeg_processor: Codec formats: [VIDEOTOOLBOX, NV12, YUV420P, BGRA, P010LE]

[AdrianEddy]

Did you try on M2? Intel devices had much more limited media processing engine in the hardware

[AfflatusX]

Yeah same results on M2. However, when choosing ProRes HQ the option showed up. I guess HEVC + P210LE isn't a valid combo for either libx265 or videotoolbox?

[wang-bin]

My m1 air supports main42210, maybe p210 is a supported format

fcc: 'hvc1' -  Apple HEVC (HW)  hw=1 {
    CodecName = HEVC;
    CodecType = 1752589105;
    DisplayName = "Apple HEVC (HW)";
    EncoderID = "com.apple.videotoolbox.videoencoder.ave.hevc";
    EncoderName = "Apple HEVC (HW)";
    IsHardwareAccelerated = 1;
    PerformanceRating = 400;
    QualityRating = 90;
    SupportedSelectionProperties =     {
        ProfileLevel =         (
            "HEVC_Main_AutoLevel",
            "HEVC_Main10_AutoLevel",
            "HEVC_Main42210_AutoLevel"
        );
    };
}

[AdrianEddy]

Hmm, doesn't look like ffmpeg supports that profile?

[wang-bin]

ffmpeg needs a patch to support p210. I've confirmed on my m1
