Hi All,
With an upgrade to F8, the FFmpeg wrapper no longer works due to a deprecated img_convert function no longer being built into the RPM's.

I've added a preliminary set of functions to move to the newer sws_scale methodology, with limited results so far:


[DllImport(AVCODEC_NATIVE_LIBRARY, CallingConvention = CALLING_CONVENTION), SuppressUnmanagedCodeSecurity]
public static extern void sws_freeContext(IntPtr SwsContext);

[DllImport(AVCODEC_NATIVE_LIBRARY, CallingConvention = CALLING_CONVENTION), SuppressUnmanagedCodeSecurity]
public static extern int sws_scale(IntPtr SwsContext,
IntPtr src,
int[] srcStride,
int srcSliceY, int srcSliceH,
IntPtr dst,
int[] dstStride);


These function calls "work" in the sense of not crashing, but don't yet produce the right set of results in the stream processor:

sws_Context = FFmpeg.sws_getContext(codecContext.width,
codecContext.height,
(int)codecContext.pix_fmt,
codecContext.width,
codecContext.height,
(int)pixFmt,
(int)FFmpeg.SWS_BICUBIC,
IntPtr.Zero,IntPtr.Zero,IntPtr.Zero);

int res = FFmpeg.sws_scale(sws_Context,pFrame, Frame.linesize,0,
codecContext.height, pFrameRGB, FrameRGB.linesize);

The output video from this is scaled vertically as if it was one line high, so the general approach is right, but there's an error here in the function definition somewhere that's causing the output to be messed up.

Here are the original C definitions of the function from FFmpeg:

SwsContext *sws_getContext(int srcW, int srcH, int srcFormat, int dstW, int dstH, int dstFormat, int flags,
SwsFilter *srcFilter, SwsFilter *dstFilter, double *param);

int sws_scale(struct SwsContext *context, uint8_t* src[], int srcStride[], int srcSliceY,
int srcSliceH, uint8_t* dst[], int dstStride[]);

Any help in correctly creating the C# wrappers for this would be greatly appreciated.

Thanks,

Euan.
