110 | Video and Music Samples | ||
111 | ----------------------- | ||
112 | This BSP includes recipes to download Ogg format video and | ||
113 | music files that can be played-back with the Video and music players | ||
114 | included in the sato images. The sample files are installed in | ||
115 | /home/Music and /home/Videos directories. | ||
116 | |||
117 | |||
118 | Adding Glxgears to image | ||
119 | ------------------------- | ||
120 | Glxgears can be added to the generated image by adding "debug-tweaks" | ||
121 | option to the extra image features variable in the default local.conf | ||
122 | before building the BSP. | ||
123 | |||
124 | e.g. to add Glxgears, locate the following line in local.conf | ||
125 | EXTRA_IMAGE_FEATURES = "debug-tweaks" | ||
126 | |||
127 | and change above line to.. | ||
