Still broken in VLC 2.1.2.

I had previously gotten Marquee working in 2.0.x as described below. Thread : Tip: How to Marquee in Python (and pitfalls) But as of 2.1.0, nothing appears when the Python binding tries to show text (re-downloaded vlc.py on 2013-11-06). Raising the instance's verbosity to 10 yielded no obvious error...

With the Python Bindings (2012-09-28), listening for timechanged works fine while playing... self.vlc_event_manager.event_attach(vlc.EventType.MediaPlayerTimeChanged, self._on_vlc_event) But if I pause, then call vlc_player.set_time(...) from my app's seek slider, VLC complies but doesn't fire a tim...

For the curious, here's how I eventually got Marquee working with the Python Bindings (2012-09-28) and VLC 2.0.2. # Gotta mention marq in the instance for marquee methods to work. # Gotta show title for marquee to be visible*. With a 1ms timeout to effectively hide the title. # Verbose -1 suppresses...

Oh, callbacks are known to be unstable and are unlikely to ever be fixed.

Okay then, I'll just write an external multi-threaded application and feed command strings to an interface script (based on cli.lua) via pipe or socket.

stream:addfilter("comma,separated,list")

I think these are the only relevant ones, which extract from a single-file archive as you read:

• zip
• stream_filter_rar

A full list of modules, some of which may be stream filters can be found here:

Hmm, doing occasional blocking stream reads in the intf-event callback lags video.
readline() was a little stuttery, but read() made VLC nearly unresponsive.
Even without dialogs.

I have an intf-event callback that acts on a variable periodically, but returns quietly when it hasn't been given a non-nil value. When I set that variable from a dialog's button callback, I think I'm seeing threads fight. u [ n 00a h f a 5 n 058 d ] l e lua generic warning: d v Error while running ...

Thanks. I missed that one. Learned a couple things... A) There's a second returned value for reporting errors, when the stream is nil: "local s, err = vlc.stream(...)" B) Add "vlc.keep_alive()" after creating the stream and after each read, to keep VLC from getting bored and term...

According to the lua readme, vlc.stream() objects can be opened, read, and filtered(?). If you neglect to read for a while, does a buffer fill to capacity and error out, or grow and eat memory? Can they be closed or polled? Are streams a subclass of something with more methods? If they don't have a ...

Can I use something like vlc.var.add_callback(vlc.object.input(), "time", pause, VAR) Input's time doesn't work, but you can do this: --Global setting for minimum seconds between callbacks. --desired_interval = 5.00 function activate() input_callback("add") end function deactiva...

In the VLC source code (/modules/lua/libs/net.c), the lua vlc.net.poll({fds}) func maps to this. i_ret = poll( p_fds, i_fds, -1 ); int poll(struct pollfd *fds, nfds_t nfds, int timeout); The timeout argument specifies an upper limit on the time for which poll() will block, in milliseconds. Specifyin...

Wow, I must've been looking at an old API doc at the time ( Google's cache circa 2012-04-12 only mentioned POST). The link I included in the post above resolved my immediate problem. "Both GET and POST requests are supported" Which means this works. curl "https://YOUR_USER:YOUR_PASS@s...

Hrm, I probably wouldn't be able to poll the a vlc.stream() object to avoid blocking.

Requesting a vlc.net func to open a TLS'd connection may be asking too much...

I'm tinkering with the idea of reading messages live from twitter (from a group of people simultaneously watching a movie) and using osd to show them as if they were subtitles... The hangup is that Twitter's live API only accepts a POST request over https. VLC's lua can do a GET by letting an access...

As of VLC 1.1.8, Goom and ProjectM visualizations are oddballs that won’t show the words, the latter can take a black-on-black oscilloscope milkdrop preset . Set wave_r, wave_g, and wave_b to 0.000000 to make the wave black. Save it to black.milk in a new directory. In VLC’s Prefs, Set Audio-Visuali...
