The bug ticket seems quite old and said to be hard to fix.
If it cannot be easily fixed, can't it at least generate an async event that can be caught and handled?

Is there at least no warning or event that is generated for this case?

Hi, I'm reading a UDP video stream and extracting frames from it. When my UDP stream dies, libVLC keeps sending the same frame over and over as if nothing special happens - as if it is continuously getting it on the stream (which is now empty). I understand that you never know when a UDP stream is d...

Thanks for the prompt reply Jean-Baptiste.

Hi,

When the VLC window is larger and/or with a different aspect ratio as the video, VLC sets the areas outside the video frames to black.
Is there a way to change this color from black to some other custom color?

Thanks!

What is the "libvlc SONAME"? Is there some flag or value that can be check or compared to see if the guarantee is broken (but not necessarily the compatibility itself)? My question is really due to the comment in the parens: "the run-time version may be more recent than build-time one...

Hi, In `libvlc_version.h` there is a comment: /* ... This file defines version macros for LibVLC. * Those macros are primilarly intended for conditional (pre)compilation. * To get the run-time LibVLC version, use libvlc_get_version() instead * (the run-time version may be more recent than build-time...

I was afraid you'd say that.
Do you happen to know if this is possible at all with ffmpeg, if I used ffmpeg directly?

Hi,

I have a multi-program transport stream. Some of the program meta-data causes libvlc (or ffmpeg?) to generate a flood warnings.
Is there a way to silence the log level of non-video streams in the transport?

Thanks,

Hi, I'm looking for a portable Linux/Windows library to demux a network video stream for use with, e.g. the Intel Media SDK which works directly on elementary (compressed/encoded video) streams. My streams are HTTP/UDP streams. I came across DVBlast and I have a few newbie questions regarding it: 1....

Yes! That was it.
Thanks.

Hi, I've got a UDP video stream that I can view and play with VLC (2.0.5). Using the same version, LibVLC hangs on the same stream. Here's the verbose log of VLC: [01d8edb0] logger interface: VLC media player - 2.0.5 Twoflower [01d8edb0] logger interface: Copyright c 1996-2012 VLC authors and VideoL...

Thanks. I'll try it.

Hi, I want to programatically disable all audio on my video stream/file. I found 2 ways of doing it: By passing "--no-audio" to libvlc_new. However, libvlc_new's comment states: "There is absolutely no warranty or promise of forward, backward and cross-platform compatibility with rega...

Do you remember why it isn't safe?

I don't know the libVLC code. Can you point me to the right files and how I get access to the ffmpeg instance?

Hi, I tried using the new libVLC 2.1.0 logging API. It seems that these logs do not contain any log messages emitted (to stderr) by ffmpeg. ffmpeg has a function av_log_set_callback() that allows hooking into its own logging calls. I don't know libVLC's code, but wouldn't it make sense to hook into ...

I noticed that I can detect these happened errors by catching the 'libvlc_MediaPlayerEncounteredError' event. However, I also noticed that the 'libvlc_MediaPlayerPlaying' event is fired even before any errors are encountered. Is there some event that says: "Currently everything is playing prope...

Not currently. And all except the "main input error" are not VLC errors, but errors from underlying libraries.

Using 2.0.x how can I catch "main input error"?

Hi,

Is there some stable release from 2.1.0?
If not, what logging API should be used with the current stable release (2.0.x)?

Thanks,
Adi

Are all these sent to stderr?

Hi, When parsing a video stream I sometime get errors and warnings from VLC that are printed to my console (on Windows). Is there a way to redirect these messages and/or capture them before they are printed to the screen? Alternatively, is there a way to suppress them, some verbosity flag? For examp...

Will that slow down the playback or actually skip frames?
What parameter/API-call achieves this?

Is there no option to ask for a reduce rate?

Hi, When reading a video stream, is it possible to indicate a particular frame rate that the callback should be called with? For example, say my stream runs at 30fps. How can I request that the callbacks (set with libvlc_video_set_callbacks()) be called only with a frame rate of 15fps? How do I spec...

In fact, you can do it.
Use libvlc_event_attach to handle the libvlc_MediaPlayerTimeChanged event.
You will only get it if the stream is changing, so if you don't get it for, say, 1 second, it means something is wrong with the stream.
Good luck,
Adi
