Then launch `vr_video_player` with the x11 window id. + +If the video is not meant to be viewed as a sphere but as a rectangle, then pass the `--flat` option when running vr video player.\ +If the video is flipped where the right eye is on the left side, then pass the `--right-left` option when running vr video player.\ +If the video is stretched, then pass the `--no-stretch`option when running vr video player. Note: This option only works when also using the `--flat` option. diff --git a/src/main.cpp b/src/main.cpp index 9706ff1..8f53ade 100644 --- a/src/main.cpp +++ b/src/main.cpp @@ -278,8 +278,15 @@ private: // X compositor GLint pixmap_texture_width = 0; GLint pixmap_texture_height = 0; + enum class ViewMode { + LEFT_RIGHT, + RIGHT_LEFT + }; + bool sphere_projection = true; double zoom = 0.0; + ViewMode view_mode = ViewMode::LEFT_RIGHT; + bool stretch = true; }; @@ -369,7 +376,7 @@ void dprintf( const char *fmt, ... ) } static void usage() { - fprintf(stderr, "usage: vr-video-player [--flat] [--zoom zoom-level] <window_id>\n"); + fprintf(stderr, "usage: vr-video-player [--flat] [--left-right|--right-left] [--stretch|--no-stretch] [--zoom zoom-level] <window_id>\n"); exit(1); } @@ -413,6 +420,14 @@ CMainApplication::CMainApplication( int argc, char *argv[] ) } else if(strcmp(argv[i], "--zoom") == 0 && i < argc - 1) { zoom = atof(argv[i + 1]); ++i; + } else if(strcmp(argv[i], "--left-right") == 0) { + view_mode = ViewMode::LEFT_RIGHT; + } else if(strcmp(argv[i], "--right-left") == 0) { + view_mode = ViewMode::RIGHT_LEFT; + } else if(strcmp(argv[i], "--stretch") == 0) { + stretch = true; + } else if(strcmp(argv[i], "--no-stretch") == 0) { + stretch = false; } else if(argv[i][0] == '-') { fprintf(stderr, "Invalid flag: %s\n", argv[i]); usage(); @@ -1524,7 +1539,7 @@ void CMainApplication::AddCubeToScene( const glm::mat4 &mat, std::vector<float> } else { - double width = 1.0 * width_ratio; + double width = (stretch ? 1.0 : 0.5) * width_ratio; double height = 0.5; AddCubeVertex(-width, height, zoom, 1.0, 0.0, vertdata); AddCubeVertex(width, height, zoom, 0.0, 0.0, vertdata); @@ -1837,11 +1852,15 @@ void CMainApplication::RenderScene( vr::Hmd_Eye nEye ) if( nEye == vr::Eye_Left ) { float offset = 0.0f; + if(view_mode == ViewMode::RIGHT_LEFT) + offset = 0.5f; glUniform1fv(m_nSceneTextureOffsetXLocation, 1, &offset); } else if( nEye == vr::Eye_Right ) { float offset = 0.5f; + if(view_mode == ViewMode::RIGHT_LEFT) + offset = 0.0f; glUniform1fv(m_nSceneTextureOffsetXLocation, 1, &offset); } |
