The demo is not working?! Is it because of "Unregistered..." message?

I didn't try your releases for long time, so maybe I missed something...

[Ionut Cristea]

  No, no is working, but with the new versions BASS_DSHOW must be registred to remove that nag screen

[muntablues]

OK, but YOUR demo is not working. VLC, WMP, etc. can play all the files I have tested with your demo...

[Ionut Cristea]

 Thats very very strange. Can you send me some files?

[muntablues]

I've tried Win7 example video (nature.wmv) and some other movies. I can not send you >1GB. Maybe you have "nature.wmv" too...

I think it would be better, if you would make a "debug" version. Maybe a richtext output after every step in your program.

[muntablues]

BTW: An older version (04/2011) of "xvideo" is working fine...

[bensam56]

The demo is working fine but want to know what is that xvideo built in render and what its using?

[Ionut Cristea]

it's a directdraw renderer and you can use it to retrive video surface and draw on it. Also this new BASS_DSHOW offer possibility to user to create his own video renderer. A Directdraw7 and Direct2D video renderers are available like samples in the new version

xVideo_Init overwrites...

Call BASS_SetConfig(BASS_CONFIG_BUFFER, 150)

...settings

[Ionut Cristea]

Yes that's true. But in the last version the buffer size is about 1 second.

[quickmic]

Yep, and that's not good for my audio-stuff. The latency is much too high. I removed xVideo_Init from my code and bassdshow is still working.

[Ionut Cristea]

  That's because BASS_DSHOW auto initialized itself when trying to create a HSTREAM with it. I will modify it so that it will not set the buffer size .

[stevenmmm]

further to the initialisation issue, i am finding that if i call BASS_Init() with a specific device number that BASS_DSHOW will set the device back to the windows default device.
Also when switching devices, even though i call xVideo_Free() and BASS_Free(), when it comes to reinitialise using BASS_Init() again i fairly often get BASS_ERROR_ALREADY errors returned - this doesnt happen if i am not loading BASS_DSHOW

[Ionut Cristea]

 Yes that's true also, in previous versions the BASS_DSHOW calls BASS_Init, in this new version i've removed this.

Hello all,

I've asked this a few times before, but I am in desperate need of an example of how to play a video in vb.net.
The simpler the better. Just so it is clear how to load bass_dshow, initialize and start a video.

It's hard to keep track with all these changes. Should I 'import', should I 'pluginload', should I start the video with the bass streamcreate or should I use dshow streamcreate?

Anybody? Please?

[Ionut Cristea]

  BASS_DSHOW is a fully BASS plugin, so you can use BASS function. For other functions like setting video use xVideo_ChannelSetWindow function

Hi,
yesterday i tried to receive audio data from a video file, but all i got was white noise which was in time with the real audio data. I use the floating-point option.
Do you have a test application which does the same job ? ( wavewriter example doesn't use floating-points )

here my code:

// video playback ( without audio, using xVideo_NOAUDIO_PROC has no effect )
videochan_=xVideo_StreamCreateFile( videofile, 0, videohandle, xVideo_STREAM_AUTOFREE | xVideo_NOAUDIO_PROC );
xVideo_ChannelSetAttribute( videochan_, xVideo_ATTRIB_VOL, 0 );

// audio decoder
videochan_audio=xVideo_StreamCreateFile( videofile, 0, videohandle_audio, xVideo_STREAM_DECODE | xVideo_DATA_FLOAT );

my callback proc:
xVideo_ChannelInfo vinfo; vinfo.nChannels=0; if ( ch==videochan ) xVideo_ChannelGetInfo( videochan_audio, &vinfo );
if ( vinfo.nChannels>0 ) xVideo_ChannelGetData( videochan_audio, (BYTE*)myFloatingBuffer, length );


I believe my code is o.k., because video is playing, i get no errors and the other audio streams ( using bass lib ) are in the same callback and decode like they should.

thank you very much
Jens

[Ionut Cristea]

xVideo_NOAUDIOPROC flag is only available on XvIDEO and not in BASS_DSHOW. about floating point, BASS_DSHOW always create a floating point audio channel so you don't need to set that flag.

[Jens]

Hi again,
i now understand how it works, thank you.

I'm loading BASS_DSHOW.dll as a bass plugin and it's playing perfect, but i get a BLUE SCREEN, when opening the task manager while playing. Even when i open thunderbird the playback is freezing for a moment. So what's happening here ? I never had a blue screen before with other video libraries.
