We've been experimenting with video / OSD graphics options such as gstreamer and Qt, some with more success than others. We also were thinking of QtMobility which seems to tick most of our requirements boxes (record/playback video, take stills, and have nice on-screen graphics). I wondered if anyone had any experiences of QtMobility running on the i.MX53? Many thanks.
Using OpenEmbedded/Yocto and meta-fsl-arm you can build and use it.
