Hello Nicolas, this is the decompiled version of the easycap viewer. Do you think that here i can find all the informations that i need to write an application that works with my devices? (a chinese phablet based on mt6592 and an acer a500) Do you think that it is possibile to use these decompiled sources to find the bug that causes the malfunction on my devices? For example, on my acer a500, the appl does not respond, after start...seems loading the libgstreamer.so it locks ...

You should probably contact the application developer to start with. I suspect that the capture is done using libusb, and only certain device (need USB host support) and chips are supported (seems like UTV007 and STK1160). If you bought the SW, you are allowed to request the LGPL source code being used. That could also tells you a bit about what is being used in GStreamer. It is possible, and completely legal, if the capture code was kept proprietary. It's the "hard" part to be honest, not everyone will be willing to give this away. There is kernel drivers that landed in 3.14, and to experiment, a libusb version was made in python to for the UTV007: <a href="https://github.com/memeruiz/usbtv007" target="_blank">https://github.com/memeruiz/usbtv007</a> Nicolas _______________________________________________ gstreamer-devel mailing list <a href="mailto:gstreamer-devel@lists.freedesktop.org">gstreamer-devel@lists.freedesktop.org</a> <a href="http://lists.freedesktop.org/mailman/listinfo/gstreamer-devel" target="_blank">http://lists.freedesktop.org/mailman/listinfo/gstreamer-devel</a> </blockquote></div>
