It looks like it has ALSA support on 32-bit OS version but doesn't have on 64-bit. I'm not sure why it works this way. The command 'vlc --list' returns much shorter list in case of 64-bit OS.

Does it mean that I should recompile VLC manually and include that output plugin?

I'm using the latest Raspberry OS Lite Bookworm. VLC was installed by using the command: sudo apt-get install vlc I've got the following error when I was trying to play a testing audio file with output ALSA device 'default': $ vlc --aout=alsa --alsa-audio-device=default test.wav VLC media player 3.0...

Thank you! I was able to get chapetrs this way after starting the playback: self.player.play() chapters = [] try: descriptions = self.player.get_full_chapter_descriptions(0) for d in descriptions: chapters.append({ "name": d.name, "time_offset": d.time_offset, "duration"...

Hi,

Is it possible to list audiobook chapters and select a particular audiobook chapter using the Python binding?

Thank you!

Bits per sample are useless. It's almost always 32 since VLC almost always decodes to single precision.

OK, but it's not hard-coded, right? I hope there should be some object in the Python bindings from which it could be fetched.
Thank you!

I was able to get the bitrate using the referenced MediaStats object: media_stats = MediaStats() if self.media.get_stats(media_stats): bitrate = round(media_stats.demux_bi...

^^^ Any Python binding expert here who could answer the question? Thank you!

Hi, Using the Python binding I need to get the codec info about HTTP stream. In the VLC UI it looks like this: https://raw.githubusercontent.com/project-owner/Peppy.doc/master/files/codec-info-1.png Using this Python code: track_info = self.media.get_tracks_info() I can get the following information...

Never mind, I found the problem - it should be 'sout' not '--sout'. So, this code works: import vlc import time inst = vlc.Instance() url = "https://rockthecradle.stream.publicradio.org/rockthecradle-tunein.mp3" param=[url, "sout=#transcode{acodec=flac}:std{access=http,mux=flac,dst=:8...

Actually Rémi's right, --sout won't work on any recent libvlc version (sort of since renderer API in libvlc). A media option will work though, by passing the option to `media_new`, because it's no different than what VLC does, but as always it's not "public supported API" and might break ...

Hmm, the second post in this thread is saying that it works. Though my example which follows that code doesn't actually work. Then it looks like the Python binding for libVLC doesn't support streaming output. Though I was able to use it about 4-5 years ago: https://github.com/oaubert/python-vlc/issu...

OK, how does the player stream without selecting renderer when I start it from command line? Does it use some default renderer?
Thanks!

Hi, I've prepared the following code using the example from this thread: import vlc import time inst = vlc.Instance() url = "https://rockthecradle.stream.publicradio.org/rockthecradle-tunein.mp3" param=[url, "--sout=#transcode{acodec=flac}:std{access=http,mux=flac,dst=10.0.0.6:8080}&q...

OK, filed the bug report:

Does it mean that only PulseAudio can set the MMAP mode? Does it also mean that there is the issue in VLC in RW mode and I need to open the bug?
Thanks!

I've found that everything works fine when PulseAudio is in use for example in the 'Raspberry Pi OS with desktop and recommended software'. In this case the content of the /proc/asound files is like this: /proc/asound/card2/pcm0p/sub0/sw_params: tstamp_mode: ENABLE period_step: 1 avail_min: 661 star...

I use VLC as a default player and it would be great to fix the issue. You mentioned that 'the device driver fails to provide stable enough timestamps'. Is that driver the part of the OS or the part of the VLC? Here is the output from the command 'cat /proc/asound/card2/stream0' for the DAC which has...

Why are there up/down sampling messages in the log when I use the following parameters when I start VLC?
--audio-resampler=disable --no-audio-time-stretch

Why different DACs work differently? One works without issues with VLC and another with issues. Doesn't VLC use the same device driver for both DACs? Thanks!

Hi, I use VLC 3.0.12 on Raspberry Pi 4 runnning Raspberry Lite OS 32-bit. I connect DACs to Pi over USB. So far I tested 3 different DACs and two players: VLC and MPV. - Alien DAC (PCM2702) doesn't have any issues with VLC and MPV players. - Topping E30 and Khadas Tone Board DAC have issues (no audi...

Hi theodore_dream, I've been using python-vlc for a long time with ALSA and never faced the issues which you described. I install it the same way (with 'sudo' for apt-get): sudo apt-get install vlc sudo apt-get install python3-pip pip3 install python-vlc I use the following startup parameters: --aou...

Does anybody know how to make python-vlc working as a streaming server? I described the issue here:
https://github.com/oaubert/python-vlc/issues/105

Thanks in advance!

This is a workaround rather than the answer to your question. There is no cvlc on Windows either but I was able to run 'vlc' without any garphical window this way:
This way you can stream without playing file in a graphical window.

Hi, If I'm creating player this way: from vlc import Instance instance = Instance("--sout=#transcode{acodec=flac}:std{access=http,mux=flac,dst=10.0.0.6:8080}") player = self.instance.media_player_new() and then trying to play some file I cannot connect to the player as a streaming server. ...
