求助，播放8K的视频，ios端颜色不对，整个画面是暗红色的

[tppqt]

4K以下都没问题，hevc的编码，8K的视频就显示不正常

你解决了没有

[tppqt]

解决了，render版本是v2的太低了，修改了代码用了v3就好了

[iWolfSex]

能提供一下代码吗

[iWolfSex]

static const char g_shader[] = IJK_GLES_STRING(
precision highp float;
varying highp vec2 vv2_Texcoord;
uniform mat3 um3_ColorConversion;
uniform lowp sampler2D us2_SamplerX;
uniform lowp sampler2D us2_SamplerY;
uniform lowp sampler2D us2_SamplerZ;

void main()
{
    mediump vec3 yuv;
    lowp    vec3 rgb;

    yuv.x = (texture2D(us2_SamplerX, vv2_Texcoord).r - (16.0 / 255.0));
    yuv.y = (texture2D(us2_SamplerY, vv2_Texcoord).r - 0.5);
    yuv.z = (texture2D(us2_SamplerZ, vv2_Texcoord).r - 0.5);
    rgb = um3_ColorConversion * yuv;
    gl_FragColor = vec4(rgb, 1);
}

);

const char *IJK_GLES2_getFragmentShader_yuv420p()
{
return g_shader;
}
是要修改这段代码吗
