Few days ago I created a repository on gitorious, http://gitorious.org/tw68. I pushed the clean room driver written by William, mine is not available for publication. My plan is to dig into it and see what improvements I can bring. Anybody interested is free to jump onboard. Currently I am not able to make any statement of usability of the free one but Willy surely can :) Best regards, Domenico Andreoli -[ Domenico Andreoli, aka cavok --[ http://www.dandreoli.com/gpgkey.asc ---[ 3A0F 2F80 F79C 678A 8936 4FEE 0677 9033 A20E BC50 -- To unsubscribe from this list: send the line "unsubscribe linux-media" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html

After having video+audio (and getting some review), we may move it to V4L/DVB tree.

The new driver, named tw68xx, is able to capture video only. My wish is to make it stable and production ready as soon as possible. So at the beginning no audio, no TS, no VBI and no overlay are supported. These functionalities would be added with time, boards and users. I am already collecting people willing to help writing and test stuff :) > Please, always c/c v4l ML when submitting your driver[1]. You may also c/c > other lists, like LKML. This will allow people to review it. I plan to publish it for a first revision by the end of January. Currently it is an external module and I would maintain that way until it is ready for the merge to the Linus' tree. This way I have not to follow a specific tree. Would it be ok for reviewers? cheers, Domenico -[ Domenico Andreoli, aka cavok --[ http://www.dandreoli.com/gpgkey.asc ---[ 3A0F 2F80 F79C 678A 8936 4FEE 0677 9033 A20E BC50 -- To unsubscribe from this list: send the line "unsubscribe linux-media" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
