I asked the person who made this button and he told me that this "error" only indicates that we have opened firefox from the Cinelerra shell, because the application is closed, and that when closing it, it warns us that we will no longer receive messages of this application.

The good thing about using xdg-open is that this command frees the shell without human interaction, in fact if you open firefox from this call button and close Cinelerra, firefox will remain open.

He told me that if in a terminal we execute the command: xdg-open http://www.cinelerra-gg.org With the browser closed, this will open it, open the indicated page and the terminal will be free to execute other commands. The same will happen with Cinelerra. But the "system" option that is used to launch this option with this line warns that the process will no longer show messages, because it has been launched from cinelerra and cinelerra will remain open and firefox has closed.

I also asked him why this did not happen in other calls that do use $CIN_BROWSER and he replied that in order to answer this question I should study the Cinelerra code in depth and that now I did not have time for this task.

He also told me that his solution is generic in C and that it will work without creating any problems for Cinelerra, but that if those responsible do not like it, it is best not to use it. In these cases, it is best to find another person, with more time, to provide a more satisfactory solution for those responsible.

Andrea, I also started getting this error message after installing the patch to use xdg-open instead of $CIN_BROWSER in the Batch Render menu which was hanging after using the help button if the browser was not already up. I may have to back this out. If you already have started Firefox or your usual browser in the usual way, it seems to be good. Further study is probably needed.

Hopefully we can find a solution that works for everyone. Using $CIN_BROWSER caused a hang and that is why the switch to xdg-open. As a reminder, the hang occurred only when no browser was up already and the ? help key in the Batch Render menu was clicked on -- then you could do no more Cinelerra processing.

RafaMar,

Thanks for the feedback and I know that your programmer acquaintance is too busy for in depth work. And it is still very much appreciated! I will see if I can find another solution because I really like the ? key. CinelerraGG programming really is much harder than anyone realizes and takes a long, long time to understand all of the intricacies and still problems creep in. -- Cin mailing list [email protected] https://lists.cinelerra-gg.org/mailman/listinfo/cin

*Walter,*

It was just a comment, but I support what's best for everyone on the programming level.

yes for the developer. using is xdg-open is better and avoids later problems great.

you do not need any approval from me friends.

I repeat again. I apologize if my comment caused any inconvenience

Do not worry. This is just the way programming works. Many times, I had to cover up the dog's ears around here because of the commentary. *RafaMar,* I understand your point of view and all of your help, feedback, and advice has been appreciated and has been used to make CinelerraGG better. Just a few comments. $CIN_BROWSER is a variable that just calls firefox.

Not true, Firefox is the default but the user can set it to anything. What happens if a person does not have firefox installed on their system?

Cinelerra does not hang and the user does not lose any work and that is what is most important. It is simply an variable that should be modernized

It is an environment variable that anyone can modernize on their own. We have a lot of old distros out there that we want to continue to work. so full of veteran users who believe they are proprietaries of the

application and will do everything possible to sink any idea that does not come from them, and much more if it comes from a newcomer.

Not at all true. We have taken and incorporated all ideas that came from anywhere.

$CIN_BROWSER is a variable that just calls firefox.

? as lomg as override in Cinelerra_rc works I'm happy ..... On users, developers, and time .... well, different users have different workflows and tastes. Some prefer relative stability. Some can live with some changes. It hardly static - people who had more time in the past for adapting to "chages!!" may not have it anymore or at least for now. Sometimes new ideas universally better (for example I like virtual desktops and "hide window into titlebar" feature), sometimes ...not so. (KDE3 vs KDE4/5, Gnome2 vs Gnome3/4 vs Unity vs xfce vs IceWm ...) I for example can't read javascript, yet Shotcut's edl export written in this language now because main developer understand this lang well ... [0] so, yeah, preferences of developers and users matters ... Again, some ideas quite universal (source code is much simpler to alter than binary, yet not trivially simple. I can fix minor problem in Python script by guide [1] yet this doesn't make Blender itself any faster [tried animated titles from OLD Openshot 1.x, just because ... fixing Py script was much faster than bringing up modern qt5. Again, philosophy of usage .. if you prefer to install binary files - distro's provided pkg or flatpack is fine. If you want or need rareconfig or modification of source .. you better to have actually compileable on your resources project] I also not big fan of removing something because yeah, removing is always simpler than reintegrating something back. Sometimes this is not thing you can avoid, in bigger projects .... like kernel or Mesa. Also, popular in many medialibraries reworking symbol/function visibility sort of assume all ext. project have enough manpower for all this follow-us refactoring..... this doesn't feel so good at receiving end :/ yet I understand sometimes there is no other way to fit some concept in ... like both 8 and 10/12 bit h264 encoding (as it was done sometime in the past). Developers don't code at inf. speed, and sometimes good idea may not age well ... Life is full of such paradoxes, computing not expection! Sorry if you hoped for cleaner sub-world ....
