I am using Icecast 2 Win32 to stream audio in conjunction with EdcastStandalone using the Ogg Vorbis and FLAC codecs due to these codecs providing better sound quality than mp3, FLAC being lossless.
When playing a stream encoded in Ogg Vorbis or FLAC using VLC Player the player stops playback and buffers the audio whenever the encoded bitrate is 0bps (as displayed in the encoder) indicating the presence of a deliberate silent interlude in the music or audio stream. Thus if there is a delay between tracks such as 2 to 4 seconds of silence between CD tracks or even longer interludes of silence between classical music tracks in symphonies and concertos which are an integral part of the compositions themselves, VLC player will stop playing while still connected to the stream waiting until it receives non-zero samples from the Icecast2 server.
As a result of this playback issue the periods of silence between tracks, and even during the middle of tracks such as classical music tracks are doubled and this is cumulative.
If there is 10 seconds of silence between tracks VLC player will stop playing the audio and the played back time display on the player will stop as well at the time when the silence or zero samples were encoded into the stream for the duration of the silence. VLC player will then remain in this state until it registers non-zero samples in the audio and then when it detects non-zero samples in the audio stream playback will resume from the point it paused. Thus if there is 10 seconds of silence VLC player will remain silent for 10 seconds frozen on say 3 minutes, 5 seconds of the track and then when the non-zero samples are picked up will start again from 3 minutes 5 seconds (the time in seconds in an Ogg Vorbis or FLAC stream or file from the start is encoded using frame numbers in the Ogg container format by design), the 10 seconds that originally expired when VLC player paused will then be played back until the time code reaches 3 minutes 15 seconds and then the non-zero samples of the music or audio will then be played 20 seconds after the first silence occurred. The duration of the silence or interlude is therefore doubled.
This issue does not occur when playing back streams encoded using mp3 since the bitrate never drops to 0bps. It only occurs when playing back Ogg Vorbis and FLAC streams and as time progresses with consecutive periods of silence the delay between the live performance and playback gets longer and longer since VLC player doubles the duration of the silence every time. This makes listening to classical music the way it was recorded practically impossible and makes listening to CD tracks frustrating as the stream gets more and more out of sync with the original source unless the player is manually stopped and started again.
Other players such as SM Player do not suffer from this issue. SM Player will buffer an Ogg Vorbis or FLAC stream for about 12 seconds and if it encounters audio samples at -infinity dB ie. zero samples it will continue playback normally with the original duration of the gaps between tracks being preserved. It does suffer from bugs playing back Ogg Vorbis or FLAC streams which cause it to repeat the last second of audio, if a track stops or silent interludes occur at -infinity dB, if the playback buffer has not been filled up properly.
These bugs have probably been there for years and it is surprising no one has noticed them before and figured out the cause.
Is it possible to fix this issue and get Ogg Vorbis and FLAC streams to play black properly?
All audio is routed digitally using:

We need the full log, from the very beginning to the very end. Please open Tools -> Messages (set Verbosity to 2) before you start the playback, keep the messages window open during the whole process and then paste the full resulting log here or on Pastebin.com or on Justpaste.it if it's too long.
Re: VLC Player not playing back silent interludes properly in streams using Ogg Vorbis and FLAC if bitrate is 0bps
Here is the log file after I placed a track on Virtual DJ after Edcast had connected to the Icecast server using the Ogg Vorbis codec. I then pressed the play button to start the track on Virtual DJ. I then pressed play on VLC player to play back the stream. The stream started playing. After a few seconds I paused the track on Virtual DJ so that the audio level was at -infinity dB, and then restarted it about 10 seconds later.
When the track was paused VLC player started glitching and repeated the last second of the track about a couple of seconds after I'd paused the track and Virtual DJ was outputting silence at -infinity dB (ie. zeros). Then after I resumed playing the track VLC player took double the length of the pause for the track to be audible again, where if I had been streaming in mp3 format instead the audio from the track would have been heard less than about 5 seconds later. At no point during this procedure was the connection to Icecast dropped.

Re: VLC Player not playing back silent interludes properly in streams using Ogg Vorbis and FLAC if bitrate is 0bps
I have found a temporary external workaround which stops this problem occurring.
1) Create a 30 second sample of white noise at amplitude 0.000015 in Audacity and save it as FLAC. Audacity will quantize it at a level of exactly -90dB even though it's at almost -96dB.
2) Place the FLAC encoded sample on one of the Sampler pads on VirtualDJ and edit the pad so that the sample plays back as a loop.
3) Click on the pad to activate the loop and keep it active while you are playing music. This will cause the Ogg Vorbis encoder in Edcast to force the bitrate to 75Kbps which stops VLC Player from thinking that the stream has stopped on encountering zero samples which causes it to stutter and buffer silence until the track has started playing again above -infinity dB or the interlude on a classical music composition has elapsed and the orchestra starts playing the next movement.
Using the FLAC encoder on Edcast will not cause the problem if the encoded bitrate is higher than 0 Kbps.
There is clearly an issue in the way Ogg encapsulated streams are processed by VLC Player and other media players including the ones built into Chromium/Edge, Mozilla Firefox, and even SM Player which causes all of them to stutter, repeat the last frame or more of audio, and/or stop playing and buffer silence whenever they encounter 0 samples (-infinity dB) in an audio stream.
If this is intended behavior then it is badly thought out. Why allow the player to stutter when a track goes silent?
If the developers of any of the above mentioned players or others are reading this can you please remove this behavior from your player. When zero samples are encountered in an Ogg stream the player should play the intended silence as intended. It should not stop, not stutter, and not buffer the silence, and then playback the buffered silence for its entire duration the moment the sound resumes at above -infinity dB doubling the duration of the silent interval in the process, which was never intended to be part of the original performance/recording, before playing back the resumed audio from rest of the streamed track or performance.
