avcodec YUV to RGB

Question

I\'m trying to convert an YUV frame to RGB using libswscale.

Here is my code :

AVFrame *RGBFrame;
SwsContext *ConversionContext;

ConversionContext =         


        

Answer 1

av_frame_alloc only allocates memory for the frame object itself, it does not allocate memory to store the image data. Have you done:

FillVect.resize( avpicture_get_size( PIX_FMT_RGB24, FrameWidth, FrameHeight ) );

somewhere in your code before calling avpicture_fill? Or some other way to make sure FillVect allocates enough memory to keep the whole decoded picture?

Did you try to run it under valgrind to see what exactly trigges SEGFAULT?
