Hi,
attached is some workaround for controlling VLC, one using
[tcpclient], and another one using dbus-send.
Both uses tcl for scripting with [hc/sys_gui]

Hello,
Now, with Pd 0.46.7 you have [netsend -b].
It allows you to send a string in 'binary' mode (you don't need anymore
to use the FUDI protocol used by netsend before).
Then, something like :
[list add file.mp4(
|
[l2s] <- from zexy library (there is vanilla solution for this)
|
[list fromsymbol]
|
[list append 10]
|
[list prepend send]
|
[list trim]
|
[netsend -b]
should work.

Hi, there. I'm trying to use PureData 0.46.7 to control VLC. Based on a
patch in https://github.com/mxa/AudioVideoPatches, that uses Python code
(pyext) to send TCP messages, I want to use [netsend] to send them,
without Python.
I start VLC with:
vlc -I rc --rc-host=localhost:1234
And, in Pd:
[connect localhost 1234(
|
| [list add file.mp4(
| [list prepend send]
| [list trim]
| /
[netsend]
The connection is well done, but I discovered that the messages arrives
with a ";" at the end of the message. For example, when I click on [list
add file.mp4(, VLC says (sorry for the language):
[0x7f387c0044a8] filesystem access error: cannot open file
/home/mario/file.mp4; (No such file or directory)
[0x7f387c0044a8] main access error: Falló lectura de archivo
[0x7f387c0044a8] main access error: VLC no pudo abrir el archivo
«/home/mario/file.mp4;» (No such file or directory).
[0x7f3888005ac8] main input error: open of
`file:///home/mario/file.mp4%3B' failed
[0x7f3888005ac8] main input error: Su entrada no puede abrirse
[0x7f3888005ac8] main input error: VLC es incapaz de abrir el MRL
«file:///home/mario/file.mp4%3B». Vea el registro para más detalles.
Also, I use a simple Python script (Server code in
https://wiki.python.org/moin/TcpCommunication) to receive this messages
and, when it does, it prints:
received data: b'add file.mp4;\n'
Ssome guys from #dataflow told me that the best workaround is to make a
small program/app/script that strips semicolons. Yes, now I'm writing
it... but I would not need another program to do this.
I've never reported a Pd bug. I'm writing this mail to you to know about
this (maybe it is not necessary to report it)... and maybe someone knows
another workaround.
Thank you.
