Audio playback and audio management components / Re: Laptop display suddenly go...
Last post by Administrator - October 30, 2023, 02:59:46 PMHello,
1. Unfortunately the K-Lite pack is still needed also if not showing the video stream
2. Please, take a look into the VideoWaveform sample project that makes use of the VideoPlayer.AudioTrackExtract method in order to extract a video file into a memory buffer (or into a temporary file by just changing the bStoreInMemory parameter from TRUE to FALSE). Once you have the memory buffer (or the temporary file) you may load it through the LoadSoundFromMemory method (or LoadSound for a temporary file).
Please, note that you don't need to extract the audio track in order to change pitch and tempo: this can be applied to the video player directly as seen inside the VideoPlayerSimple sample project.
Hope this helps
Kind regards

Audio playback and audio management components / Re: Laptop display suddenly go...
Last post by Ravindra - October 30, 2023, 02:19:57 PMHello Severino,
Thanks for Solution. I have some questions.
1. If I do not load video window it works, and play only Audio. Does that eliminates the need of K-lite codec
pack ?
2. I tried with VideoPlayer.AudioTrackExtract method but not able to use it. I need the snippet of code how to extract please. Let me know can I get a wave file (.wav..) after extracting the audio and can I change pitch and tempo of this file ?
Does Extract method takes longer time ?
Thanks and Regards
Ravindra.

yes, this is possible: you simply need to avoid adding the video window which is created through the VideoPlayer.VideoWindowAdd method: in this case only the audio stream of the video clip will be instanced and rendered.
You can test this situation by using the VideoPlayerSimple sample project and commenting out the VideoPlayer.VideoWindowAdd method inside the source code.
In case you should need to extract the audio stream into a brand new WAV audio file (or W64 if bigger than 2 GBytes), you may use the VideoPlayer.AudioTrackExtract method.
In case you should need to extract the audio stream into a brand new audio file of a format different from WAV, like MP3 or Opus, our recorder component comes with the ExtractAudioFromVideoFile method which allows extracting and exporting the audio stream into one of the many supported formats.
Kind regards

Is it possible to play only Audio (mp3, wav) from a video file without displaying video on screen?
In short can I extract only Audio from Video file ? And later should be able to change pitch and tempo.
I know its weird question but have such requirement.
Thanks and Regards,

unfortunately we cannot suggest definitive solutions for this kind of problems happening on a specific kind of laptop configuration: the only suggestion is to try updating the video card driver and trying to play with existing K-Lite settings.

Audio playback and audio management components / Laptop display suddenly goes w...
Last post by Ravindra - October 13, 2023, 05:32:49 PMHello,
I am facing an issue on laptop,
1. CPU - i5
2. Ram - 8 GB
3. Windows 11 OS
4. Nvidia Graphics Driver
when I start a video in my application the screen flickers and display goes off.
Already Installed K-lite codec.
1. I kept K-lite Hardware acceleration at None because keeping any other accelerator problem still persists.
__________________________________________________________
The problem does not exists on similar laptop configuration without Nvidia Graphics drivers.
Can you suggest any solution to resolve the issue.
Regards,
Ravindra.

Audio playback and audio management components / Re: Video Window Resizing
Last post by Administrator - July 22, 2023, 11:35:26 AMHello,
the window hosting the video rendering isn't aware about the resizing of the container panel so it needs to be resized accordingly through the VideoPlayer.VideoWindowMove method.
An example of usage of this method can be found inside the VideoMultipleOutput and VideoPlayerAdvanced sample projects.
Hope this helps

Audio playback and audio management components / Video Window Resizing
Last post by Ravindra - July 21, 2023, 02:37:28 PMHi,
I have put the Video window (Label) in one of the panel of Splitter Container. The label is Dock to Fill the entire area of the panel. When I start video it looks perfectly alright.
When I collapse all other panel except a video window panel to view a video in big size, i see that my label for
Video window is grown but the video size remain the same. It does not stretch itself to fit the label video window.
Can you suggest any solution so that Video will also become big and occupy full space?
I am attaching the images.

being quite older, version 7 of AudioDjStudio has never been tested under Windows 11 but there should be no known reason for which it should not work.
Version 14 of the AdjMmsEng engine is certainly compatible with Windows 11 so you should not have problems. The latest builds 14.4.0.3 are available on our web sites ar the following URLs:

Audio playback and audio management components / Compatibility with Windows 11
Last post by Ravindra - July 20, 2023, 03:12:33 PMHello,
I am currently switched to following platform,
OS: Windows 10 Pro
Language: Visual Basic
Visual Studio 2022 Community Edition
AudioDJStudio version : 7.3.1.0
AdjMmsEng.dll version : 14.4.0.0
AdjMmsEng64.dll version : 14.4.0.0
It works fine as of now.
Now the requirement is to install the application on Windows 11.
Let me know if the above AudioDJ components are compatible for Windows 11 installation.
If i am left over with the updated latest versions of AdjMmsEng.dll and AdjMmsEng64.dll which might have been released after the existing versions which i am using.
Can you provide me those latest updated versions if i am eligible to get ?
Thanks and Regards,
Ravindra.
