(Where) can I find the the full list of the (key) differences between SAA7113 and GM7113? If it is not hard to do it, can anybody please implement it? Unfortunately, I'm not very good with system drivers programming. I'm interesting only in sharpness control because the image quality (sharpness) during capture using CVBS input is bad (on my EasyCap device). If I use S-Video input, the quality (sharpness) is better. It is important to implement it, because the sharpness control implemented in hardware (not in software, post-processing filtering). Control of other parameters like gamma are also don't work, but I'm not sure that gamma control is hardware (not software) implemented (I'm not found any info about gamma in saa7113 datasheet). -- To unsubscribe from this list: send the line "unsubscribe linux-media" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
