When using ChannelSetSync function, the application freeze occurs.
Would my code be wrong?

The code:

m_hStream = xVideo_StreamCreateFile((PVOID)lpFilePath, 0, hWnd,BASS_STREAM_DECODE | xVideo_UNICODE);
xVideo_ChannelSetWindow(m_hStream, 0, hVideoScreen);
vidStream = m_hStream;
m_hStream = BASS_FX_TempoCreate(m_hStream, BASS_FX_FREESOURCE);
BASS_ChannelSetAttribute(m_hStream, BASS_ATTRIB_TEMPO, 200.0f);
ChannelSetSync(BASS_SYNC_END, 0, LoopSyncProc, (DWORD *)&vidStream);
BASS_ChannelPlay(m_hStream,false);

void CALLBACK LoopSyncProc(HSYNC handle, DWORD channel, DWORD data, void *user)
{
    HSTREAM* pStream = (HSTREAM*)user;
    xVideo_StreamFree(*pStream);
    m_hStream = xVideo_StreamCreateFile((PVOID)TEXT("test.avi"), 0, 0, BASS_STREAM_DECODE | xVideo_UNICODE);
}

WHen creating decode streams you must save the value returned first by creating stream function;

Thanks a lot

Hi, Ionut.

When calling xVideo_ChannelResizeWindow function, may not work depending on the calling timing.

1st code, xVideo_ChannelResizeWindow function works correctly.

m_hStream = xVideo_StreamCreateFile((PVOID)lpFilePath, 0, hWnd,BASS_STREAM_DECODE | xVideo_UNICODE);
xVideo_ChannelSetWindow(m_hStream, 0, hVideoScreen);
xVideo_ChannelResizeWindow(m_hStream, 0, 0, 0, 100, 100);
m_hStream = BASS_FX_TempoCreate(m_hStream, BASS_FX_FREESOURCE);
BASS_ChannelSetAttribute(m_hStream, BASS_ATTRIB_TEMPO, 200.0f);
BASS_ChannelPlay(m_hStream,false);

2nd code, xVideo_ChannelResizeWindow function does not work correctly.

m_hStream = xVideo_StreamCreateFile((PVOID)lpFilePath, 0, hWnd,BASS_STREAM_DECODE | xVideo_UNICODE);
xVideo_ChannelSetWindow(m_hStream, 0, hVideoScreen);
m_hStream = BASS_FX_TempoCreate(m_hStream, BASS_FX_FREESOURCE);
xVideo_ChannelResizeWindow(m_hStream, 0, 0, 0, 100, 100);
BASS_ChannelSetAttribute(m_hStream, BASS_ATTRIB_TEMPO, 200.0f);
BASS_ChannelPlay(m_hStream,false);

Have you tried latest version also?(note you'll need bassmix also )

Yes, I use BASS_DSHOW.DLL(102KB) version 1.2.2.0 with bassmix.dll version 2.4.6.0.

And I tried using BASS_DSHOW.DLL(275KB) you have uploaded, but 0xC0000005 Access Violation error occurs when calling xVideo_StreamCreateFile function.

Good morning, Ionut. Current time is AM 6:54 in Japan

Even if setting the speed to 0%(no change), the audio timing is delayed to the video screen.

Test code:

m_hStream = xVideo_StreamCreateFile((PVOID)lpFilePath, 0, hWnd,BASS_STREAM_DECODE | xVideo_UNICODE);
xVideo_ChannelSetWindow(m_hStream, 0, hVideoScreen);
m_hStream = BASS_FX_TempoCreate(m_hStream, BASS_FX_FREESOURCE);
BASS_ChannelSetAttribute(m_hStream, BASS_ATTRIB_TEMPO, 0.0f);
BASS_ChannelPlay(m_hStream,false);

  What bass error it give?

Oh, I'm sorry. I was able to change the speed in the previous code

By the way, the audio timing is delayed to the video screen.
Ways to improve it is Nothing?

Try like this:

m_hStream = xVideo_StreamCreateFile((PVOID)lpFilePath, 0, hWnd,BASS_STREAM_DECODE | xVideo_UNICODE);
xVideo_ChannelSetWindow(m_hStream, 0, hVideoScreen);
m_hStream = BASS_FX_TempoCreate(m_hStream, BASS_FX_FREESOURCE);
BASS_ChannelSetAttribute(m_hStream, BASS_ATTRIB_TEMPO, 200.0f);
BASS_ChannelPlay(m_hStream,false);

It can play the video, but can not change the speed

First code will not play, you only can extract audio data.

2nd code, do you have any error code?

Error code '1' ( xVideo_INVALIDCHAN ) is returned.

Thanks, Ionut. But the code does not work well.

First, when adding BASS_STREAM_DECODE flag, the video is played very slowly.

m_hStream = xVideo_StreamCreateFile((PVOID)lpFilePath, 0, hWnd,BASS_STREAM_DECODE | xVideo_UNICODE);
xVideo_ChannelSetWindow(m_hStream, 0, hVideoScreen);
xVideo_ChannelPlay(m_hStream);

Next, I tried the code below. But the video is not played. Something wrong?

m_hStream = xVideo_StreamCreateFile((PVOID)lpFilePath, 0, hWnd,BASS_STREAM_DECODE | xVideo_UNICODE);
xVideo_ChannelSetWindow(m_hStream, 0, hVideoScreen);
m_hStream = BASS_FX_TempoCreate(m_hStream, BASS_FX_FREESOURCE);
BASS_ChannelSetAttribute(m_hStream, BASS_ATTRIB_TEMPO, 200.0f);
xVideo_ChannelPlay(m_hStream);

Nope,

Just use BASS_PluginLoad("BASS_DSHOW.dll",0) and fallow bass_fx samples.

Thanks, Ionut.

I tried the code below, it can playing a video but can not change the speed of the video.
My code is wrong?

----
m_hStream = xVideo_StreamCreateFile((PVOID)lpFilePath, 0, hWnd, xVideo_UNICODE);
xVideo_ChannelSetWindow(m_hStream, 0, hVideoScreen);
BASS_FX_TempoCreate(m_hStream, BASS_FX_FREESOURCE);
BASS_ChannelSetAttribute(m_hStream, BASS_ATTRIB_TEMPO, 200.0f);
xVideo_ChannelPlay(m_hStream);

Nope is not available , but you can use BASS_FX addon for that.

Thanks, Ionut.
For using BASS_FX addon with BASS_DSHOW, use xVideo_LoadPlugin?

Hi, Ionut.

I want to change pitch, tempo using BASS_DSHOW in my C++ windows program.
But is xVideo_FX_PITCHTEMPO flag not available on BASS_DSHOW?
