* ffbuild/common: Make deletion of templates possibleAndreas Rheinhardt2021-02-07
| | | | | | | | | | If a target to be built includes a template file, the target's .d file includes the template file as a prerequisite; if the code were changed so that the template file no longer exists, one would get an error from make that it has no rule for the template file target. Therefore add a dummy rule for template files to make deleting them possible. Signed-off-by: Andreas Rheinhardt <andreas.rheinhardt@gmail.com>

* avdevice/xcbgrab: don't assume xserver endiannessAndriy Gelman2021-02-06
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | xserver defines the endianness of the grabbed images. Use this information to set the correct pixel format. This also fixes format selection in configuration depth=32/bpp=32 with xserver on a little endian machine. Before the patch, the big endian layout 0RGB was always selected which is incorrect because BGR0 should be used. RGB24 was also incorrectly assumed (but this format was removed in xserver 1.20). The big-endian settings can be tested using docker+qemu from a little-endian machine: $ docker run --rm --privileged multiarch/qemu-user-static --reset -p yes $ docker run --rm -it -v /tmp:/tmp powerpc64/debian /bin/bash In docker container $ apt-get update $ apt-get install xvfb $ apt-get install x11-apps To test AV_PIX_FMT_0RGB32 $ Xvfb :2 -screen 0 720x480x24 & $ export DISPLAY=:2 $ xclock -geometry 720x480 -bg green #test different colors On your host machine grab the frames using the following command. View output to check that colors are rendered correctly $ ./ffmpeg -y -f x11grab -i :2.0 -codec:v mpeg2video out.mp4 Other pixel formats can be tested by modifying how Xvfb is started in the docker container: AV_PIX_FMT_RGB565 $ Xvfb :2 -screen 0 720x480x16 AV_PIX_FMT_RGB555 $ Xvfb :2 -screen 0 720x480x15 AV_PIX_FMT_BGR24 / AV_PIX_FMT_RGB24 This is difficult to test because bpp=24 support was removed in xserver 1.20 https://lists.x.org/archives/xorg-devel/2018-February/056175.html?hmsr=joyk.com&utm_source=joyk.com&utm_medium=referral However, I was able to run previous version of Xvfb (with some modifications to force 24bpp) to check that images are rendered correctly.

* avformat/rtsp: Fix build failure when RTP demuxers are disabledAndreas Rheinhardt2021-02-03
| | | | | | | | | | | | | | | rtsp.c uses a check of the form "if (CONFIG_RTSP_DEMUXER && ...) {}" with the intent to make the code compilable even though the part guarded by this check contains calls to functions that don't exist when the RTSP demuxer is disabled. Yet even then compilers still need a declaration of all the functions in the dead code block and error out if not (due to our usage of -Werror=implicit-function-declaration) and no such declaration exists for a static function in rtsp.c. Simply adding a declaration leads to a "used but never defined" warning, therefore this commit resorts to an #if.
