Question

我在iOS设备上使用Qt（特别是5.5）而不是模拟器我只是将Video对象添加到QML代码中以播放HLS流，如下所示。

Video {
    id: livePlayer
    anchors.fill: parent
    source: "http://content.jwplatform.com/manifests/vM7nH0Kl.m3u8"
    autoPlay: true
}

但是Qt给我回复了以下日志的错误

Failed to find shader  ":/qtmultimediaquicktools/shaders/rgbvideo.vert"
Failed to find shader ":/qtmultimediaquicktools/shaders/rgbvideo.frag"
QOpenGLShader::link: "ERROR: Compiled vertex shader was corrupt.\nERROR: Compiled fragment shader was corrupt.\n"
shader compilation failed: 
"ERROR: Compiled vertex shader was corrupt.\nERROR: Compiled fragment shader was corrupt.\n"
QOpenGLShader::link: "ERROR: Compiled vertex shader was corrupt.\nERROR: Compiled fragment shader was corrupt.\n"
QOpenGLShaderProgram::uniformLocation( qt_Matrix ): shader program is not linked
QOpenGLShaderProgram::uniformLocation( rgbTexture ): shader program is not linked
QOpenGLShaderProgram::uniformLocation( opacity ): shader program is not linked

我正在做的事情我可以 - 清洁，运行QMake，等等 - 但它没用。给我一些帮助PLZ。

谢天谢天。

这是Qt 5.5分支中的临时错误。

要使用当前的5.5快照修复它，请将其添加到main()功能：

Q_INIT_RESOURCE(qtmultimediaquicktools);

此问题已在Qt的当前5.5分支find the fix here中修复，或等待下一个快照。
