Luigi Rizzo	7a1dcff6a6	Build console_video support by linking in, as opposed to including, console_video.c This will ease the task of splitting console_video.c into its components (V4L and X11 grabbers, various video codecs and packetizers, SDL), as well as ease future extensions (e.g. additional video sources, codecs and rendering engines). For the time being nothing changes for users: video support is off by default, and requires -DHAVE_VIDEO_CONSOLE on the command line to be included (if SDL and FFMPEG are available). git-svn-id: https://origsvn.digium.com/svn/asterisk/trunk@94615 65c4cc65-6c06-0410-ace0-fbb531ad65f3	19 years ago
Luigi Rizzo	b7adaa023c	add some macros to simplify parsing the config file, see description in config.h . They are a variant of the set of macros i used in chan_oss.c, structured in a way to be more robust to the presence of spurious ';' - basically, they define wrappers for 'do {' and '} while (0)', plus some helper functions to deal with simple cases such as ast_copy_string, ast_malloc, strtoul, ast_true ... The prefix (CV_ as 'Config Variable') tries to be easy to remember and has been chosen to not conflict with other existing macros in the tree. For the time being, I have only updated the three source files in the tree that used the old M_* macros. Hopefully, more files will be converted. NOTE: I understand that inventing my own dialect of C is generally wrong; however, the lack of adequate support in the language encourages lazy programming practices (such as ignoring errors, bounds, etc.) and this increases the chance of vulnerability in the code, especially because we are parsing user input here. Hopefully, these macros and the use of ast_parse_arg (in config.h) should encourage the programmer to write more robust code. git-svn-id: https://origsvn.digium.com/svn/asterisk/trunk@94191 65c4cc65-6c06-0410-ace0-fbb531ad65f3	19 years ago
Luigi Rizzo	5e84c0554e	Add instructions on how to generate your own font. git-svn-id: https://origsvn.digium.com/svn/asterisk/trunk@94002 65c4cc65-6c06-0410-ace0-fbb531ad65f3	19 years ago
Luigi Rizzo	573d94759d	Bring in video console support for chan_oss (and later chan_alsa too). This is disabled in the default build, you need to explicitly enable it compiling with make COPTS=-DHAVE_VIDEO_CONSOLE In return, you will be able to do a video call with chan_oss, using the webcam (or X11 grabbing) as local source, and rendering the incoming stream on your screen. Currently supported formats are h261, h263, h263+, h264, mpeg4 (all through the avcodec lib, part of ffmpeg). Incoming video is on the left, outgoing video is on the right, while the center displays a keypad (if configured so). Right clicking on the video windows increases the size, center clicking reduces the size. Dragging the mouse (with the left key) on the right window while the X11 grabber is active moves the grab area. This is the result of work by Sergio Fadda, Marta Carbone and myself, all properly disclaimed to digium. Note, there is a lot of work left to do in this module, including adding support for Video4LinuxV2 (I have patches from Matteo Brancaleoni which should be integrated), and making the GUI a lot more friendly than it is now (e.g. supporting merging or switching among multiple sources, a text window, and more). git-svn-id: https://origsvn.digium.com/svn/asterisk/trunk@93144 65c4cc65-6c06-0410-ace0-fbb531ad65f3	19 years ago
