Hi, Up to now, i am not aware of any reports of people trying to work with this new sunxi-cedarx library. (strangely, after so much asking/begging directly to allwinner to "open-source" the cedarx library) You are the first (to my knowledge), that is trying to use this library, meaning that the only answer to the question i can give is, i don't know if this new cedarx library runs ok. (i still didn't arrange time to look more in detail and actually try it) If you happen to get some success, please report back. Or even better, help the next person(s) avoid the trouble that you are having by adding your finding to the linux-sunxi wiki? Maybe in a new page like in http://linux-sunxi.org/sunxi-cedarx > 1. ./bootstrap > 2. ./configure --prefix=/home/test/ --host=arm-linux-gnueabihf (im > not sure the parameter is ok or not) > 3. make && make install Did you also tried by compiling natively? If not, try first this way, before going for cross-compiling. > > then so file generated, then run demo in sunxi-cedarx/demo/vencoder > on A20 board, then tell me segment fault... Then run under a debugger and see where the segment fault is happening, if is in open-source part, then it can be fixed because to segment fault is itself a bug, and should have checks and instead print a error message, which helps to see what is wrong or missing. If is in the close-source-plugin, then there isn't much that can be done, other than maybe, more asking/begging allwinner to release a new close-source-plugin-binary which with some luck could fix the issue. > it's strange that there is no code to call VEncoderRegister function > in Venc_device.c. Not strange at all, this new open-source cedarx library is dependent in the use of close-source-plugin-binaries to offer the encoding feature that you wish to use. > > > On Tuesday, May 19, 2015 at 8:47:45 AM UTC+8, kevin.z.m.zh wrote: > > > > Hi All, > > > > We're proud to announce a new code release today for CedarX.
