[Cin] Upd: Historical question about Broadcast2000

[Andrew Randrianasulu]

Actually, I compiled it for my (x86, 32bit userspace) machine!

Only bad thing it doesn't draw those nice video thumbnails ...

Input video was done  by CinelerraCV 
(just set output to quicktime/MJPEG-a) :}

Actully, this pre-Cinelerra even renders :}

But not sure if ALSA interfaces remained stable ...
(currently it pretend to use OSS)

quick fun ....

objcopy -L dv_peek_vlc parse.o 
(removing conflicting object from libquicktime/libdv/parse.o)
hint from https://forums.gentoo.org/viewtopic-t-7560-start-0.html

set global configure to this state:
only part of configure shown

########################## COMPILER
EOF

if test -z "$CFLAGS"; then
        echo >> global_config "CFLAGS = -O2 -fpermissive -fomit-frame-pointer -malign-loops=2 -malign-jumps=2 -malign-functions=2 -march=i486 -I/usr/local/include"
fi

echo >> global_config "CFLAGS += -D_LARGEFILE_SOURCE -D_LARGEFILE64_SOURCE -D_FILE_OFFSET_BITS=64"

########################## DEVICE DRIVERS
cat >> global_config << EOF
CFLAGS += -I.
CFLAGS += -DHAVE_OSS
### CFLAGS += -DHAVE_ESOUND
#CFLAGS += -DHAVE_ALSA
##CFLAGS += -DHAVE_FIREWIRE

---
basically added -fpermissive to CFLAGS, and disabled Esound/Fireware.
also disabled mmx, in quicktime's configure

in ipc.c in root directory 

//#include <linux/linkage.h>

was commented out by me.

after make install and checkinstall I have my Slackware package :}

gcc 5.5.0 / glibc-2.23 / kernel 5.1 / X server 1.19.7 :} 

most important thing - I got my 
bcast-2000c-src-2001-01-22.tar.gz

from srpm, I think ....

Ah, no here it is, too
http://linuxmafia.com/pub/linux/apps/

surprizingly enough, Console  look like small 4-item window, 
so no free graphical routing for me :}

Hello, all!

Not sure if anyone will be able to answer this, but I was reading archived page about Broadcast2000
(out of it Cinelerra was born) and found interesting paragraph:

https://web.archive.org/web/20010623135738/http://heroinewarrior.com/bcast2000/console.html

THE CONSOLE

    When Broadcast 2000 plays back, it reads large chunks of data from disk, asynchronously sends small fragments through the console, and overlays the output of each module onto the output channels. The same thing happens for video, but video is overlayed on a single output frame instead of channels. Make sure Window->show console is checked, to bring up the console. As you can see, each track on the timeline is routed through a module.

    It's possible to even synthesize sounds from the console but you must turn off disable tracks when no edits in preferences->playback.

    Start playing a file and tweek the faders. The O buttons reset the meters in case you clip. The pan box was designed to support more than 2 channels. For 2 channel panning, more precision can be achieved by moving the cross to the bottom of the box and panning left and right. Track titles can be entered from the console as well.

    Resize the console window and see what happens.

I wonder how it looked and worked?

was it a bit like Node-based editing? (I only saw few videos about Blender and Natron using this mode, never used it myself.)

If enough infrastructure remains in Cinelerra for supporting this mode - may be it can be re-instanced ....?

I for example can imagine grouping two stereo tracks into 'Eng' and 'Rus' audio tracks in avi/mpeg2/mkv container .....
Not sure if today you can do this in one pass in Cinelerra?

Also, shared effect idea makes a bit more sense now, at least for me ...

I saw few more references to Broadcast2000:

comments are mostly ..low-quality, but this is history now :}

I hope this one will stay within archive.org at least ....

Seriously, 2X 1000Mhz P3 was way above anything I hand back in those years

Two more historical screenshots (probably they missed from archive.org's 
copy of Cinelerra/Broadcast2000 website  - never saw them before ...)

This one about Cinelerra already (from 2008) but still I watched small movie 
from last comment :}

May be one of those days I will prepare VM with old linux and try to compile something
as uncompileable as broadcast2000 :}
