Some Dolby videos play normally on Windows and iPhone but stutter, display incorrect colors, and crash on Android phones.

Hi , I forked fvp and modified fvp/tree/master/example/lib/main.dart.
I changed

fvp.registerWith()

to

fvp.registerWith(
      options: {
        // Subtitle fully disabled (you already confirmed this works)
        'subtitle.enabled': 'no',
        'subtitle.auto': 'no',
        'subtitle.default': 'no',
        'subtitle.preferred': '',
        'ffmpeg.enable.all': '1',
        // Prefer hardware decoders that preserve 10-bit
        'video.decoders': [
          'D3D11VA',
          'NVDEC',
          'VAAPI',
          'VideoToolbox',
          'AMediaCodec',
          'FFmpeg',
        ],
        // HDR + 10-bit + Tone Mapping + Metadata Passthrough
        'videoout.hdr': 'yes', // Master HDR switch
        'videoout.hdr10_metadata':
            'yes', // Send HDR10/HDR10+ metadata to display
        'videoout.tone_mapping':
            'hable', // Best perceptual tone mapper (or 'mobius', 'reinhard')
        'videoout.tone_mapping.mode': 'auto', // Auto: HDR→SDR when needed
        'videoout.color_space':
            'auto', // Let MDK detect BT.709 / BT.2020 / DCI-P3
        'videoout.color_transfer': 'auto',
        // Optional: For low-latency HDR streaming
        'lowLatency': 1,
      },
    )

and updated the remote media URL from

to

. After compiling, the video colors display correctly on Windows and iOS (as shown in the first image), but the colors are incorrect on Android (as shown in the second image).and When I play this video on my Android phone, it stutters significantly, and the player crashes after about ten seconds. I suspect the Android system is killing the process rather than it being a bug in the player itself; the crash might be triggered by system protection mechanisms due to excessive memory usage. This video plays normally on other players.

Is there a solution to ensure this video displays correctly on Android as well? Using mpv's `gpu-next` allows the colors to render correctly on the Android system.

if you have crash, upload crash log and libmdk.so*, otherwise i can do nothing if can't reproduce on my device. I've updated issue template and add how to add crash log

your video does not have dolby vision information in mkv container, so I skip parsing metadata in my decoders, but ffmpeg based sw decoders and hwaccels always parse metadata, so color is correct on some platforms with your configuration. It's easy to fix.

it stutters significantly

stutter should be fixed in the latest libmdk, see #384 , upgrade dependencies

stutter and crash can be in different issues

android color issue is fixed in the latest libmdk, you can upgrade dependency to test
