* OpenCL: Fix ABI incompatibility issuesManeesh Gupta2015-04-28
| | | | | | | | | AVOpenCLDeviceNode and AVOpenCLPlatformNode used fixed static buffer for holding the device and platform name. This patch modifies these structures to use pointers instead. The memory required to hold the names is now dynamically allocated, the size for which is determined by querying appropriate OpenCL runtime APIs.

* avutil/opencl: is_compiled flag not being cleared in av_opencl_uninitSrikanth G2015-03-06
| | | | | | | | | | | | When OpenCL kernels are compiled, is_compiled flag is being set for each kernel. But, in opencl uninit, this flag is not being cleared. This causes an error when an OpenCL kernel is tried on different OpenCL devices on same platform. Here is the patch with a fix Reviewed-by; Wei Gao <highgod0401@gmail.com> Signed-off-by: Michael Niedermayer <michaelni@gmx.at>
