QUESTION

GStreamer C library not working properly on Xubuntu

Asked 2021-Jun-15 at 11:39

I am writing a program in C language using gtk3 library. I want it to be able to receive a h264 video stream from a certain IP address (localhost) and UDP/RTP PORT (5000).

In order to do it, I am using gstreamer to both stream and receive the video.

I managed to stream the video using the following pipeline :

send.sh :

gst-launch-1.0 filesrc location=sample-mp4-file.mp4 ! decodebin ! x264enc ! 'video/x-h264, stream-format=(string)byte-stream' ! h264parse ! rtph264p

I managed to display the video in a new window using the following pipeline :

receive.sh :

gst-launch-1.0 udpsrc port=5000 caps="application/x-rtp,encoding-name=H264" ! rtph264depay ! decodebin ! videoconvert ! autovideosink

At this point, everything works fine. But now I want to receive the stream and display it inside my C/GTK program. I am using the following code (found on internet and adapted to make it compile) :

Here is the solution I found :

Changin xvimagesink by ximagesink :

sink = gst_element_factory_make ("xvimagesink", NULL); g_assert(sink);

becomes

sink = gst_element_factory_make ("ximagesink", NULL); g_assert(sink);

Hope it will help some of you facing the same problem.

QUESTION

In gtk-rs, how do I get the current screen that a gtk::Window is (mostly) on?

Asked 2021-May-22 at 17:11

What I'm trying to accomplish is to calculate the dpi (or, in my case, the dpmm) of the screen that my application is mostly on. So far as I know, the modern way to do that is to call gdk::Monitor::get_height_mm and gdk::Monitor::get_width_mm.

So, starting with window: gtk::Window, I'm trying to get the Monitor like so:

ANSWER

Answered 2021-May-22 at 17:11

A gtk::Window is not the same as a gdk::Window. The former is more like the concept of a "window", while the latter maps better to the concept of X windows. In other display protocols, these are also called "surfaces", which is why it got renamed in GTK 4, also to clear up this confusion.

In any case, to get the underlying surface/window of a widget in GTK, you can call the get_window() method on it (in gtk-rs, this is part of the gtk::WidgetExt trait)

ANSWER

Answered 2021-Apr-27 at 18:50

You can use -o /dev/null to discard the output altogether, or you could send it to a temporary file which you then delete. If you're concerned with compile times, you can add -E in order to only run the preprocessor, which is the minimum in order for -H to work. That works because if you tell gcc to stop after preprocessing (-H), it doesn't matter if you also tell it to stop after creating an object file (-c). (That's an exception to the general rule that gcc uses the last of a set of conflicting options, which is designed to let you override options by adding to the end of a command-line.)

However, I can't help thinking that this is not really the best solution to your problem. It seems like you've hand-crafted a compiler invocation with a number of options, and then put it somewhere where it's difficult to modify. A better solution would be to use a makefile and set the value of the various standard makefile variables -- such as CFLAGS, CPPFLAGS, LDFLAGS, LDLIBS -- which are documented in the Gnu make manual. In simple cases, your Makefile might consist only of lines which set these variables, since Gnu make has built-in rules for common targets.

How do I change the text of a label after clicking a button using GtkAda

I have this code which has 1 label and 3 buttons. What I want is to change the text of the label if I press a certain button. If I click the first button the label text will change to "Hello" and if I click the second button the label text will change to "World" and lastly if I click the third button the label text should become "Hello World".

ANSWER

Answered 2021-Apr-05 at 17:29

You have to add a callback to buttons to modify the label, in a very similar way like it is done in GTK. I didn't use GTKAda by some time, but it should work:

You need to add -DGWEATHER_I_KNOW_THIS_IS_UNSTABLE to your C compilation arguments. If you're using Meson, GNOME Clocks has a good example.

Be sure you understand why the library authors make you do this. The library API/ABI might still change in the future, and you may have to update your code accordingly if that happens. (For example, there's an open merge request to remove all the GTK widgets so the rest of the library can link with GTK4 apps).

There are not css nodes to margins in textview. You need to use functions like set_left_margin(left_margin) set_right_margin(right_margin) or set_justification(justification).

By default the build type is release. A debug build can specified as. for a debug optimized build. Pass --enable-rust to build the rust-electrum single signature support as used by e.g. Aqua. By default builds use link time optimisation. It can be disabled when invoking build.sh. For example. To build using clang-analyzer use. The clang-tidy targets are enabled if found in the PATH. Extra options exist to specify version of it,. then use as follows. A sanitizer build can be invoked using. where <type> is any available sanitizer of your choice and available on the toolchain being used. A different compiler version can be specified as. which allows for multiple side by side installs of compilers in common linux distributions.
Use clang-5.0, no LTO, enable clang-tidy and debug build. Use address sanitizer with gcc-7, no LTO, enable clang-tidy and debug build. Use clang-analyzer (it'll analyze GDK and its direct dependencies).
