Asterisk Team commented on ASTERISK-28836:
------------------------------------------

Thanks for creating a report! The issue has entered the triage process. That means the issue will wait in this status until a Bug Marshal has an opportunity to review the issue. Once the issue has been reviewed you will receive comments regarding the next steps towards resolution.

A good first step is for you to review the [Asterisk Issue Guidelines|https://wiki.asterisk.org/wiki/display/AST/Asterisk+Issue+Guidelines] if you haven't already. The guidelines detail what is expected from an Asterisk issue report.

Then, if you are submitting a patch, please review the [Patch Contribution Process|https://wiki.asterisk.org/wiki/display/AST/Patch+Contribution+Process].

Please note that once your issue enters an open state it has been accepted. As Asterisk is an open source project there is no guarantee or timeframe on when your issue will be looked into. If you need expedient resolution you will need to find and pay a suitable developer. Asking for an update on your issue will not yield any progress on it and will not result in a response. All updates are posted to the issue when they occur.

>      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?
