I made a quality-check filter that used with VirtualDub as avi-reading application.
For output log I was needed an input filename because I start VirtualDub in batch mode for processing all files in folder.
Currently made my own custom build of VD 1.9.7 with changes:
in vdvideofilt.h
| CODE |
// VDXFilterActivation: This is what is actually passed to filters at runtime.
class VDXFilterActivation {
public:
const VDXFilterDefinition *filter; //
void *filter_data;
VDXFBitmap& dst;
VDXFBitmap& src;
VDXFBitmap *_reserved0;
VDXFBitmap *const last;
uint32 x1;
uint32 y1;
uint32 x2;
uint32 y2;
VDXFilterStateInfo *pfsi;
IVDXFilterPreview *ifp;
IVDXFilterPreview2 *ifp2; // (V11+)
uint32 mSourceFrameCount; // (V14+)
VDXFBitmap *const *mpSourceFrames; // (V14+)
VDXFBitmap *const *mpOutputFrames; // (V14+)
// ADDED
wchar_t szInputAVIFile[MAX_PATH];
IVDXAContext *mpVDXA; // (V15+)
};
|
in FilterInstance.h
| CODE |
class VDFilterActivationImpl { // clone of VDXFilterActivation
VDFilterActivationImpl(const VDFilterActivationImpl&);
VDFilterActivationImpl& operator=(const VDFilterActivationImpl&);
public:
VDFilterActivationImpl(VDXFBitmap& _dst, VDXFBitmap& _src, VDXFBitmap *_last);
const VDXFilterDefinition *filter;
void *filter_data;
VDXFBitmap& dst;
VDXFBitmap& src;
VDXFBitmap *_reserved0;
VDXFBitmap *const last;
uint32 x1;
uint32 y1;
uint32 x2;
uint32 y2;
VDXFilterStateInfo *pfsi;
IVDXFilterPreview *ifp;
IVDXFilterPreview2 *ifp2; // (V11+)
uint32 mSourceFrameCount;
VDXFBitmap *const *mpSourceFrames; // (V14+)
VDXFBitmap *const *mpOutputFrames; // (V14+)
// ADDED
wchar_t szInputAVIFile[MAX_PATH];
IVDXAContext *mpVDXA; // (V15+)
private:
char mSizeCheckSentinel;
VDXFBitmap *mOutputFrameArray[1];
};
|
in FilterInstance.cpp
| CODE |
// ADDED
extern wchar_t g_szInputAVIFile[];
FilterInstance::FilterInstance(FilterDefinitionInstance *fdi)
{skipped}
{
filter = const_cast<FilterDefinition *>(&fdi->Attach());
src.hdc = NULL;
dst.hdc = NULL;
last->hdc = NULL;
x1 = 0;
y1 = 0;
x2 = 0;
y2 = 0;
// ADDED
wcscpy(szInputAVIFile, g_szInputAVIFile);

That allows filter to get input filename as szInputAVIFile member of FilterActivation structure. Can you add this feature in official releases ?
Or may be other way of getting input filename for the filter already exist ? |

Sorry, but I'll have to decline. Video filters deliberately don't have access to this information, because they're not supposed to know about the source file, only the source stream. For instance, it doesn't make sense in capture mode, if the stream is dynamically generated, or if there are multiple source files.

Well - what other ways of getting input filename officially available ?
May be getting list of file handles opened by the process with current Process ID and filtering out all files in the VirtualDub's folder and lower ? |
