Note: This article assumes that:. your device is actually supported by the drivers - Just because your board happens to have a chip on it that corresponds to some existing driver does NOT mean your product is supported. The driver has to be aware that it's related to some hardware (typically through the ). If the driver doesn't recognize/bind to your particular hardware, then the module will probably load but then proceed to not do anything. In other words, support for your device would have to be added to the driver. you have already physically installed the hardware device into, or connected it to, your system. (Refer to the manufacturer's instructions for such details).
Contents.Software Requirements Kernel SupportThe LinuxTV V4L-DVB drivers are developed against the upstream Kernel, at the.Yet, some volunteers maintain a which provides support for older Kernels. Currently, those backports are tested with driver builds since Kernel 2.6.36, but that changes over time. Also, due to kernel API changes, not all drivers are supported on older versions.Please also notice that, while the backport developers try to do their best, usually the backport tests done consists solely on checking if the driver builds with older Kernels.So, if you need to use a driver on a version where it is currently unsupported, or if you find any issues that aren't present on upstream Kernel, you may need to write a backport patch.
Note: If you are using Ubuntu, you were previously very likely to run into a fatal compilation error within the v4l-dvb build process when it reaches the firedtv module. The reason for this is because Ubuntu had a bug in their packaging of the kernel headers. This seems to be fixed on a fully updated systtem (5 July 2011) This was a long standing issue, and one of the most frequently reported on the mailing list.If you still have the problem, you should be able to correct this compilation problem by following the more manual procedure listed below. In particular, before proceeding to build the modules, you will have to edit the file v4l/.config and change the line for the firedtv driver from 'firedtv=m' to 'firedtv=n'.
Note: The build script will clone the entire media-tree.git, which will take some time. Using -depth 1 argument creates a faster clone, but it drops patch historyIn order to modify a driver foo.c:cd mediagedit drivers/media/video/foo.cmake -C./v4lmake -C./ installmake -C.

Rmmodmodprobe foo(some procedure to test the 'foo' driver)To generate a patch, use:git commit -asThen submit the patch upstream. If your sendmail is properly configured, you can easily send the patch upstream with:git send-email HEAD^1or, to send a patch series:git send-email initialbranchWhere initialbranch is the name of a branch of a changeset number for the last patch before your changes.git clonecd mediabuild/linuxmake tar DIR=make untarcd.If you need to make any sort of change or modification to the source code, now is the time. Optional Pre-Compilation StepsThese optional command steps are applicable only in certain situations approaching a new build of the driver set, or for experienced users wishing to streamline the build process to consist of only those components they want to install. make rminstall. You would use this to remove the currently installed driver set (located within the relevant /lib/modules/'kernel version'/kernel/drivers/media directory to which they were installed). make distclean.
Cleans up the build configuration environment. Noteworthy is that it will set things up such that a following 'make' build process will be against ' /usr/src/uname -r” kernel source.
make menuconfig. This will open up the ncurses based menu that allows you to select only those components you wish to build and installThe building system offers some other make targets that may be useful for advanced users or developers. For listing the supported targets, please use make help.Next, build/compile the modules from the source code with the command:make. Note: For multi-core processor systems, the make command has available options that can be beneficial in terms of the reducing the amount of time required for the process' completion. Specifically, you can run ' make -jN' (where ' N' = 1 + the number of cores your cpu has. Note: The Daily Automated Build TestsHans Verkuil has set up an automated daily build of the V4L-DVB source code upon all supported kernels, as well as testing that very same upon several CPU architectures. A brief synopsis of the results from those tests is published each day on the Linux-Media Mailing List (LMML) under a message subject heading prefix of ' cron job v4l-dvb daily build.'
For Advanced UsersThe following information is likely useful only for developers.
