iVidCapPro has been updated to be compatible with Unity 4.5. With this version the post-build processing to automatically modify the UniyAppController.mm file should be working again. As usual, you can download the plugin here:
If you continue to have post-build issues with iVidCapPro in Unity 4.5 please let me know.
On a (probably) unrelated note, I’ve had a couple of reports of blank (black) frames at the beginning of videos recorded with iVidCapPro. I’ve seen this intermittently myself, but I don’t have a testcase that reproduces it reliably. If you have a simple testcase that does so, please let me know by posting here or contact me at firstname.lastname@example.org. Even better, if you have noted this issue and have a fix for it, please contact me so I can share it!
