GStreamer iMX6 Image Display

GStreamer iMX6 Image Display

There is no Freescale GStreamer element which does the JPEG decoding, so we must rely on a standard one, like 'jpegdec'. In case your Linux system was built using LTIB, in order to have the jpegdec element included on the gst-plugin-good, follow these steps:

 

1. On the LTIB menuconfig, make sure the following packages are selected:
   1. gstreamer-plugins-good
   2. libjpeg
   3. libpng
2. Remove the configure parameters '--disbale-libpng' and '--disable-jpeg' on the file './dist/lfs-5.1/gst-plugins-good/gst-plugins-good.spec'
3. Rebuild and flash your board (or SD card) again.
