Hi all, I would love to hear from anybody who owns any sample of PCIE board with TW5864 chip.
It is possible to buy from here http://www.provideo.com.tw/Products.htm?link=web/DVR%20Card_Hardward.htm I guess there are more companies selling boards with it. So there is a driver, "tw5864", submitted and accepted upstream, currently in linux-next, I guess it will get into Linux v4.9. https://git.kernel.org/cgit/linux/kernel/git/next/linux-next.git/tree/drivers/media/pci/tw5864 Then there is a pile of sources from vendor, obfuscated and bloated, not very human-readable, but that is what our painful development started with: http://lizard.bluecherry.net/~autkin/tw5864/TW-3XX_Linux.rar TW5864 datasheet from manufacturer: http://lizard.bluecherry.net/~autkin/tw5864/tw5864b1-ds.pdf Recently a developer from another company contacted us, reporting that our driver doesn't work well on samples they had, and sharing quite different driver sources from their vendor, which work fine. Those sources were also obfuscated, but much less, and they have successfully deobfuscated by them. Link to the code: https://github.com/bluecherrydvr/linux/tree/master/drivers/media/pci/Isil5864 This second driver is interesting because on some samples it really works well, despite the upstreamed driver gives worse picture. I cannot work on that productively because my hardware sample is not affected. That's why some communication with other owners would be useful. Oh and of course Intersil (current owner of Techwell labs) technical support is useless, just stating that development team was dismissed several years ago. (By the way, if anybody is aware of different PCI Express boards with both analog input decoders and video compression encoders, except solo6x10, which are easy to buy and to run on Linux, please let us know). -- 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
