Hi Severino,

Today, creating a new build for one of our applications using MMS (AudioDjStudioF4.dll).
Always ran a rather old version (control 10.1.0.0 / engine 13.1.1.6) but updated to latest version (control 11.3.0.0 / engine 14.3.0.4)

But now I get a lot of "*** Internal Error, cannot load engine Number 12 due to error 126" errors.
A lot is, one in 5 application starts.

Also noticed that when I got this error, the content of one of the bass-dll's was written into my application logfile.
See attached image..


Tried writing text data using different way (FilePointer / StreamWriter) but that did not help.
Also checked windows antivirus software, but no mentioning for blocked files...

Do you know at what point the bass dll's are written?
Maybe I can disable all my read/write actions until the dll files are written..

Hi Severino,

Just a quick question;
Is it possible to or on the roadmap, the option to play/stream to Sonos speakers (UPnP/DLNA device).

Have a nice weekend!

Hi Severino,

At first the best wishes for 2023.

We have an WPF application (.net 4.6.2) that is playing several videofiles at the same time.
The application contains the "Audio DJ Studio for .net" component, but the issue also occurs when using the "API for .net" component
The ADJ control is initialized using the WASAPI sound system and nine (9) decks are initialized.
deck 8 and 9 are used for continuously play a list of MP4 AAC/AVC files (ambient files).
These files have various lengths between 7seconds and 2 minutes.
2 other decks are used for playing video adds. Also MP4 AAC/AVC files.

Sometimes, when a file is loaded (using .Load or .LoadSync), everything seems to go OK.
No error is raised and retrieving total time after LoadDone is raised, gives the correct total time.

But when we start the playback of the track (using .play or .playrange command) this results in an ERR_GENERIC or ERR_TIMEOUT error. and the track is not started.

Current system is Windows 11, K-lite is latest version.
Do you know if there are any limitations (qty loaded tracks?) or workarounds to handle this issue?

Best regards

Hi Severino,

Is there a way to get the id's (or names) of the existing cue points or trigger points?

Hi severino,

I currently noticed on 2 devices the following issue:
When I load a MP4 file without setting the audio output device (Default Directsound Device), the file is loaded without any issues, and the file (video and audio) is played as expected.
But when I set the audio output to an other output (Directsound: Speaker (Realtek (R) Audio)) and load the same MP4 file, I get an ERR_INVALID_FORMAT error.

The issue can be reproduced using the VideoPlayerSimple example (vb.net) in 32bit mode.
K-Lite is installed, Windows codecs disabled
AudioRenderMode is set to Audio_Renderer_Mode_Custom_2
Tested with AdjMmsEng.dll ver 13.1.0.2 and ver 13.6.0.17

Please advise

Best regards

Hi Severino,

Could you help me out with the following issue.
I am trying to create a playlist with crossfade functionality using the AudioDJStudioApiF4 control. (version 10.1.0.0 / Engine 13.6.0.17)
The playlist is created from scratch using the PlayListCreateEx and PlayListAddItem procedure.
When I create the playlist without crossfade functionality, the second track is automatically started when the first raises a Done event (both on DeckA).
But when I add the Fader object, the second track is started and directly raises a done event.

Could you hint me what I am doing wrong?

Please find below the debug logging and VB.Net code.

Hi Severino,
I am currently facing an issue where a tick occurs in the sound of a playing videoclip (in deck 1).
This occurs when a second videoclip is loaded in deck 2.

This occurs when using AdjMmsEng.dll version 13.6.0.0 and 13.6.0.16
When using AdjMmsEng.dll version 13.1.0.2, there is no click.

It does not make any difference when using 'DisplayVideoPlayer.LoadSync' or 'DisplayVideoPlayer.Sync'

The used videofiles are MP4 (AVC/AAC - full HD)
The installed codec is K-Lite version 15.4.8 or newer

Find attached the code I used

Please advise...

Best regards
Patrick Vossen

There was a typo in the text file with code:
"Private Const PlayerB As Short = 2" should be "Private Const PlayerB As Short = 1"

Hi Severino,

One of the thing where we use MMS for, is playing internet radio.
This always works without any issues.
But as of today the engine cannot open the streams any more and the control returns a stream_load_fail.
When I open the link in a browser (Chrome or Firefox) or in VLC, the links still can be played.
I guess that the provider changed something what results in a not able to open the stream using MMS

Do you have a more detailed reason for this stream_load_fail result?

One of the links for the radio station is https://20133.live.streamtheworld.com/RADIO10.mp3

Hi,

Retrieving the shuffled playlist order does not seem to work.

I have a playlist that's loaded from .pdj file containing 3 files (using PlayListLoadSync, PlayListLoad does not seem to work at all).
The PlaylistSetShuffle option is set to true (was already set before loading the pdj-file).
On the PlayListLoadDone-event, I do a call to PlayListExecOrderTableGet to retrieve the PlayOrder.
Result for this is    2 - 1 - 0
The playlist starts playing and on the PlaylistSoundLoaded-event I log the indexes that are played.
The result for this is    2 - 0 - 1

Hi Severino,

We are using the MMS engine for playing (streaming) mp3 files from several network locations.
Some customers experience errors where the engine returns STREAM_LOAD_FAIL on loading the stream.
Is there a way to get the real error (404 or timeout or something else) instead of the generic message STREAM_LOAD_FAIL?

Hi Severino,

I noticed when creating a playlist file (.pdj), the complete path is used.
Is there a way to only use the filename in the .pdj file and set the soundsdirectory for the control?

Best regards
Patrick Vossen

Hi Severino,

I am trying to create a playlist-file (wpl or pdj) for using with the ADJ component, but I noticed that, when adding a filename with an &-sign in the filename, the file is not found by the control and removed from the playlist.
When manually creating a playlist with the demo application and saving the playlist I notice that the &-sign is saved as &amp;
Is there a list what chars needs to be converted to html entries (e.g. the space is NOT converted to &nbsp;)

Hello,

I've got some questions;

• When I set drivertype to WASAPI, does the videoplayer also use the wasapi driver type?
• Does it make any difference what audio_render_mode is used? I am using the AUDIO_RENDERER_MODE_CUSTOM_2

Best regards,

Hi Severino,

Is it possible to cancel an fade-out action after setting the StreamVolumeSmoothingSet-function?
I noticed that when setting

Code Select Expand

audioDjStudio1.StreamVolumeSmoothingSet(e.nPlayerIndex, False, 5000, enumVolumeCurves.VOLUME_CURVE_LINEAR, -1)
And calling

Code Select Expand

audioDjStudio1.StopSound(Player_A)
The player starts to fade out (=OK), but then when I want to stop the song during the fade-out time, I can call

Code Select Expand

audioDjStudio1.StreamVolumeSmoothingSet(e.nPlayerIndex, False, 0, enumVolumeCurves.VOLUME_CURVE_LINEAR, -1)
And calling 'StopSound' again, the song directly stops, but when I start the song again, the first Fade action is continuing to Fade-out.

Is there a way to cancel this Fade-out action?

Best regards

Hello,
We have noticed a crackle/tick in the sound when loading a videofile into the engine.
This occurs on several W10 systems with several soundcard types. (onboard/usb/pci)
I guess that this tick is in the soundcard, not in the application, I also noticed it when listening to internet radio in Chrome browser and when loading a MP4 (AAC/AVC) into the MMS engine the crackle occurs. The used codec is latest KLite (LAV) but also on W10 codecs.
I have checked and issue occurs with AdjMmsEng v10.7 but also with v13.1.1.6.

Has someone a solution for this?
Grtz Patrick Vossen

Hello,

Sometimes we have the issue that loading an MP4 file takes "forever".
We have a backup routine that tries to reload the file if loading has not finished within 15~20sec.
But when this issue occurs the loading of a file in that deck results in a ERR_PLAYER_BUSY response.
Closing the player does not reset the player state, the only way to reset this, is restarting the application.
Is there a way to reset this player state?
If possible an other way then resetting (reinitialize) the engine.
Our player has 6 decks and one of the other decks is playing (video) at that moment.

We have seen this issue on WinXP up to Win10 (32bit) and used codec is LAV (K-Lite) on MMS version 6 up to 9.

Hello,

Is there a known limitation that audioDJStudio cannot handle bluetooth speakers?
It seems that or, InitSoundSystem fails or when trying to start a player, everythings seems OK but the the sound is not played (also no progress on SoundPositionGet).

I have noticed this same behaviour in the past when using Dante virtual soundcard.

Hello,

Is it possible to stream/cast to a network port in MP3/AGG/AAC format from a streammixer?
The same like the AudioDjStudio1.CastingWmaNetworkOpenForStreamMixer command but not in a WMA format?
Maybe using the BASS_ChannelSetAttribute function?

Best regards
Patrick Vossen

Hello,

At this moment, when casting to a network port (using CastingWma..) and listening to it using internetradio example, there is a delay of approx. 5 seconds.
Is it possible to reduce this delay?

Hello,

I am current facing the following:
When loading a file from https location into player-index 0 and start playing, everything is OK.
When loading a the following file (can be the same file from https or a different file from https) into player index 0 and pless play, after approximately 2.5 seconds the sound stutters.
Even when using a .closesound command, this stutter is present.

I have changed the soundcard from Onboard HD to MAYA44 USB+. This does not solve this.

The update buffer and INET settings are all default.

• audioDjStudio1.BufferLength = 500
• audioDjStudio1.BufferUpdateTime = 100
• Value_INET_SETTING_BUFFER_LENGTH = 5000
• Value_INET_SETTING_CONNECT_TIMEOUT = 5000
• Value_INET_SETTING_FTP_PASSIVE_MODE = 1
• Value_INET_SETTING_PREBUFF_PERC = 75
• Value_INET_SETTING_PREBUFF_PLAYBACK_PERC = 90
• Value_INET_INET_SETTING_READ_TIMEOUT = 0

Please advice...

Best regards,
Patrick Vossen
