You just made my point. I'm showing the development team there is a bug that resulted from a software change. The version I'm using was from a few days ago. I built it , then uploaded an installer. A few posts up from here.https://celestia.space/forum/memberlist.php?mode=viewprofile&u=3934. Try installing that version. You'll see what I see. Probably.???

Now I'm trying as many checks as I can, and found a problem:
the Ctrl+V command (to cycle the renderpath) is not working for me.

1.7 supports only opengl 2.1 (or opengl es 2.0) based render path

[quote:onetwothree] 1.7 supports only opengl 2.1 (or opengl es 2.0) based render path[/quote]
Thank you onetwothree, now it's clear.
A doubt: in the images folder info.txt file I read that
"you can create subfolders to organize and classify audio files for various needs"
I put a sounds folder there, with a .wav file, and tried the command "play" in a cel file to listen to it.
No way.
So I suppose that this will be for a future use, TBA?, correct?
And, BTW, thanks a lot to all the people that gave their time, skill and brain to issue the very welcome 1.7 Celestia release! :clap: :clap: :clap:

Audio support was added in Alexell times, but the wrong way. One day we implement it properly.

Thank you onetwothree, as I supposed. :wink:
Don't know if you are aware that many years ago Vincent Giangiulio prepared a special Celestia 1.6.1 edition, that was including the capability to use sounds in cel/celx scripts.
It works very well, its only drawback is that it can use .wav files only, no .mp3 or .flac or whatelse.
If you have not it, and think it could be usefull, I can share it.

I wonder how audio should it be implemented, does there exist a cross platform library for playing audio? having a binary is not very useful since we cannot extract code from the binary, but thanks for suggesting that.

Added after 13 minutes 30 seconds:
looks like there is, found this https://github.com/mackron/miniaudio which supports almost all platforms even UWP, which OpenAL seems not to support.

We added great multimedia ffmpeg library to capture video, we'll use it to play audio as well.

Could you provide full path for example to libavcodec/avcodec.h and libavcodec.so?

The for those file installed by yast is

Code: Select all

/usr/include/ffmpeg/libavcodec/avcodec.h
and

Code: Select all

/usr/lib64/libavcodec.so

The version I built and installed are

Code: Select all

/usr/local/include/libavcodec/avcodec.h
and

Code: Select all

/usr/local/lib/libavcodec.a
So the one I built has static libs. Again the ones installed by yast are not found and the ones I built get the warning and the build errors when running make.

Added after 1 minute 29 seconds:
I'll try to rebuild ffmpeg with shared libs.

That gave me an idea. I tried editing FindFFMPEG.cmake. It did find ffmpeg, still got warnings, but it still didn't work. celestia_celx failed so whatever I did was wrong. Because the paths were not correct. This is what I tried

Code: Select all

if(FFMPEG_USE_AVCODEC)
  find_ffmpeg_lib(AVCODEC ffmpeg/libavcodec/avcodec.h avcodec)
etc for the other lines. If that is what your were planning, it won't work. Celestia_celx fails because on of the ffmpeg header files is not found. But I did mirror ffmpeg to /usr/local/lib64 and usr/local/include. After that everything works. But that's a hack. So it will work if you get cmake paths right.

As far as the window installer I did. I'm still unsure how to go about testing translations. I'm guessing that I need to set up my computer to use a different language and it would be done automatically? I don't see any options to change languages in celestia itself.

In FindFFMPEG.cmake you should see find_path inside of find_ffmpeg_lib macro. Try to add HINTS /usr/include/ffmpeg or PATH_SUFFIXES ffmpeg into it.

so it should be
find_path(${__name}_INCLUDE_DIR HINTS /usr/include/ffmpeg ${__header})
or
find_path(${__name}_INCLUDE_DIR PATH_SUFFIXES ffmpeg ${__header})

I used your first suggestion last night but didn't have the {$_headrer} at the end and it still failed. But adding that {$_headrer} doesn't work either. Still fails to build celx_celestia.cpp.

I guess other linux distributions may have their own way of installing FFMpeg too?

Here is the file. In the beginning of the file I have this.

Code: Select all

########################
# EXTERNAL cache entries
########################

//Path to a file.
AVCODEC_INCLUDE_DIR:PATH=/usr/include/ffmpeg

//Path to a library.
AVCODEC_LIBRARY:FILEPATH=/usr/lib64/libavcodec.so

//Path to a file.
AVFORMAT_INCLUDE_DIR:PATH=/usr/include/ffmpeg

//Path to a library.

//Path to a file.
AVUTIL_INCLUDE_DIR:PATH=/usr/include/ffmpeg

//Path to a library.
AVUTIL_LIBRARY:FILEPATH=/usr/lib64/libavutil.so

The path is correct except for the actual file

Added after 2 hours:
Not that it matters but I noticed a couple of other things about FFMEG.cmake. AVDEVICE is never looked for but is in the file at the bottom. And there is a duplicate entry at the bottom of the file for FFMPEG::AVUTIL. But what seems to be happening is that cmake is finding the files but not passing their location to the compiler.

Added after 6 hours 15 minutes:
About translations. I now know the windows translations are not working and need a lot of work or I need a lot of education on how to use them. Anyhow with suse linux, the translations work fine. I'm able to get German translations in Celestia.

Also, I'm in the process of building ffmpeg with vcpkg. A long process. I noticed that x264 is disabled when building the ffmpeg tree. So I may be able to get that to work on the win32 version but for now, without x264.

It works with problems. ffmpeg does open the video dialog so I'll have to look at this a while.

Added after 3 hours 52 minutes:
I think that most of the code is working but the build process still needs a lot of work. Did I see that y'all were about to abandon the cmake and go with ninga or conda builds? Maybe that would be a good thing :wink:

Added after 25 minutes 46 seconds:

If you inspect you'll see some words are being translated. This is running on linux so.......

Added after 7 minutes 7 seconds:
Point here is to say the translations that work sit alongside the celestia folder in the /share folder. In windows all these folder get installed in c: And they don't work no matter where I put them.

A new installer for windows with ffmpeg enabled for video capture
(141.5 MiB) Downloaded 88 times


Just FYI to all. The movie capture has a slight bug. After starting Celestia, My first movie capture fails. An error popup appears saying the file could not be saved. The red screen appears in pause. After keying in F11, it says it's recording but the timer stays at zero. After keying in F12, the screen disappears and no file is created. Then it works normally. I was able to create videos at will. My Linux system with the qt5 version does not have this problem. The other installer on the previous page was deleted.

Actually i wasn't able to test windows ui with ffmpeg because it's not possible to crosscompile ffmpeg on gnu/linux using vcpkg now.
