>             Project: Asterisk
>          Issue Type: Bug
>      Security Level: None
>          Components: Channels/chan_oss
>    Affects Versions: 13.32.0, 16.9.0, 17.3.0
>            Reporter: Alexander Traud
>            Severity: Minor

> In the script configure, while going through all AST_EXT_LIB_SETUP, I find more and more code which is dead. That means, external projects are not used anymore too. This time, this is HAVE_FFMPEG, HAVE_SDL, HAVE_SDL_IMAGE, HAVE_VIDEODEV_H, and HAVE_X11.
> That code is not maintained anymore since June 2008. It is guarded by the Define HAVE_VIDEO_CONSOLE. The project was ‘console_video’. It is used in the Console Channel Driver for the Open Sound System {{channels/chan_oss}}. That Define must be set manually, therefore this code slipped through all the years. In the year 2011, with GitHub-Commit [c26c190|https://github.com/asterisk/asterisk/commit/c26c190711a1bbe3b5fff1a93facae333757c56e] for Asterisk 10, it got disabled completely.
> The problem is not so much the dead code. The problem is the script {{./configure}}. With every run, those libraries/headers are (tried to be) detected. Since Ubuntu 16.04 LTS (or even earlier) the following packages are involved:
> - libavcodec-dev, fails because symbol moved to libswscale/swscale.h
> - libavutil-dev, fails because Defines used but not included
> - libswscale-dev, fails because header file moved
> - libsdl1.2-dev, works
> - libsdl-image1.2-dev, works
> - libv4l-dev, fails because header file moved to libv4l1-videodev.h
> - libx11-dev, works
> This might confuse novice users who read the output of the script {{./configure}}: “Video, I want video. Why can’t I configure that? Why does it fail?” People waste time understanding and enabling this. Even after
> - changing those two paths in the script configure and in the source,
> - #define HAVE_VIDEO_CONSOLE not in chan_oss.c but in console_video.h,
> - #include <libavutil/pixfmt.h> in channels/vgrabbers.c for PIX_FMT_,
> still the code does not build. Too much changed in Asterisk and FFmpeg in the last 12 years.
> I asked the original author Luigi Rizzo two years ago and he is not using that code anymore himself. Therefore, what about removing those parts within the script {{./configure}}, at least?
