Re: [Cin] Valgrind

[Phyllis Smith]

Andrea,
GG checked into GIT the changes as was in the 2 files sent yesterday along
with 4 fixes that came out of your Valgrinds so that is a really good
thing.  Each valgrind produced results for improvement.  When/if you have
time could you do 1 more because the 2nd one you did already had the LV2
plugins loaded?  So the first time AFTER you did a build, when you run
Cinelerra it will reload the plugins so that is when you have to have
Valgrind going.  If you miss, then in Settings->Preferences, the Interface
tab, you can "reload plugins" and that will load them again (and make sure
you have valgrind going).

To run gdb, this is how I do it.
First do what you did:

> Before doing a gdb is better to do a "make clean" and then

0) you only have to do CFLAGS step one time after each bld.sh step

1) cd cinelerra_path/cinelerra
2) gdb ./ci
(gdb) handle SIG32 pass nostop noprint
(gdb) set pa off
run

Don't give up! Let us know where/if you get stopped again.



But gdb still doesn't work:

Re: [Cin] Tracking (or tracer?) control points

[Phyllis Smith]

Ugin,
I have created a demo of how to use Tracer to create something similar to
what you noted in your first referenced youtube video. It is not a very
good demo at all but it shows how to do it.  It is at:
https://streamable.com/fenacw
For best results, the more points you provide using Tracer makes the
outline more exact.  Tracer usage is described in the Manual and is easy to
use once you figure it out.  If you have problems using it, just email
here.  Andrea is much more capable of using it than I am.

If you have problems using it let us know and let us know if it works for
you.  If you think it needs something else, please outline.gg/phyllis

[Cin] Tracking (or tracer?) control points

[preobraz]

Hi all!

In the video (watch from 1:13):
https://www.youtube.com/watch?v=3kzKhedIX1o
shows how a clip is inserted into a chromakey area. I looked at the 
Tracer effect in Cinelerra-gg, but I still did not understand whether it 
was possible to perform a similar task with it.
If there are no such instruments in Cinelerra-gg - maybe try to adapt 
the Motion effect to the task?  I think solving this issue will add 
cinelerra-gg even more professionalism.


For information: in Adobe After Effects,Screen Replacement & Motion 
Tracking solves this problem. Example:

Re: [Cin] Valgrind

[Andrea paz]

I enclose the new Valgrind, made after the replacement of pluginlv2.C
and pluginlv2.h I played a bit with the height of the tracks and also
with "collects effects" and "paste effects".

But gdb still doesn't work:

Use the "file" or "exec-file" command.
(gdb)

I'm too incompetent to understand anything, I'm sorry.
I used the command to valgrind:

# CFLAGS=-ggdb make -j16 rebuild_all

To make a gdb we have to give the same command. I didn't give the
command this second time thinking it was enough to give it first.
Didn't I? Before doing a gdb is better to do a "make clean" and then
again "./bld.sh" followed by "CFLAGS=-ggdb make -j16 rebuild_all"?
