2010-10-21[media] tvp5150: COMPOSITE0 input should not force-enable TV modePaul Walmsley
When digitizing composite video from a analog videotape source using the TVP5150's first composite input channel, the captured stream exhibits tearing and synchronization problems[1]. It turns out that commit c0477ad9feca01bd8eff95d7482c33753d05c700 caused "TV mode" (as opposed to "VCR mode" or "auto-detect") to be forcibly enabled for both composite inputs. According to the chip documentation[2], "TV mode" disables a "chrominance trap" input filter, which appears to be necessary for high-quality video capture from an analog videotape source. [ Commit c7c0b34c27bbf0671807e902fbfea6270c8f138d subsequently restricted the problem to the first composite input, apparently inadvertently. ] Since any type of composite signal source can be connected to the TVP5150's first composite input, unconditionally forcing "TV mode" isn't correct. There doesn't appear to be a good way for applications to tell the driver what is connected. Fortunately, the TVP5150 has an operating mode auto-detection feature, which, when enabled, should cause the TVP5150 to auto-detect whether it should use "VCR mode" or "TV mode". Enabling operating mode auto-detection improved video capture quality significantly[3]. Therefore, fix this bug by using operating mode auto-detection. (Also, while here, fix a CodingStyle issue.) For those users who may find this patch via a mailing list archive but who are not able to upgrade to a kernel with a fixed driver: the TVP5150's S-Video and second composite input sources have auto-detection enabled, so you may wish to try using those -- if available on your device -- until this fix makes it a downstream distribution near you. 1.
