How to change vlc source code to append motiondetect filter timestamps to the log?

[Ars]

Please move this to the appropriate section.
 
https://github.com/videolan/vlc-3.0/blob/master/modules/video_filter/motiondetect.c

I see a line at the end:

Code: Select all

msg_Dbg( p_filter, "Counted %d moving shapes.", j );

this is similar to (resulting log):

motiondetect debug: Counted 3 moving shapes.
motiondetect debug: Counted 5 moving shapes.
motiondetect debug: Counted 2 moving shapes.

Ideally, the log should look like this:

motiondetect debug: Counted 3 moving shapes (timestamp 00:01:23.342).
motiondetect debug: Counted 5 moving shapes (timestamp 00:01:23.425).
motiondetect debug: Counted 2 moving shapes (timestamp 00:01:23.508).

Instead of timestamp, the frame number will also be great.

How do it?

Please move this to the appropriate section.

I changed the last line of code to:

Code: Select all

msg_Dbg( p_filter, "Counted %d moving shapes.", p_picture->date );

packed back to vlc-3.0.10.tar.gz
opened a directory with this archive on the command line and executed (in ubuntu 16.04):

Code: Select all

tar xvfz vlc-3.0.10.tar.gz ./configure

received a series of errors and modified the command:

Code: Select all

./configure --disable-lua --disable-avcodec --disable-swscale --disable-a52

but I keep getting errors like:

configure: error: No package .. found.

Am I doing something wrong overall?
Or is it necessary to work with every error?

UPD:
it looks like it helped move on:

Code: Select all

sudo apt-get gksudo gksudo gedit /etc/apt/sources.list

...deleted the # in front of the lines for universe...

Code: Select all

sudo apt-get update sudo apt-get build-dep vlc

but next error:

configure: error: protoc compiler needed for chromecast was not found

solved:

Code: Select all

sudo apt-get install protobuf-compiler

Next error and solution: https://forum.videolan.org/viewtopic.php?t=153414

last error (without solution):

...

upd2:
completely cleaned the directory and started from the beginning:

Code: Select all

sudo apt-get install git build-essential pkg-config libtool automake autopoint gettext git clone git://git.videolan.org/vlc.git cd vlc

...edited motiondetect.c...

Code: Select all

sudo apt-get install flex sudo apt-get install bison ./bootstrap sudo apt-get build-dep vlc ./configure --disable-lua --disable-avcodec --disable-swscale --disable-a52 --disable-xcb --disable-qt make

upd3:
cleared the directory and repeated all from upd2 again, but with vlc 3.0 and returned to:

...

I do not know where to move this topic as it is not about Lua scripts.
