From https://www.ffmpeg.org/doxygen/trunk/frame_8h_source.html#l00309 typedef struct AVFrame { #define AV_NUM_DATA_POINTERS 8 /** * pointer to the picture/channel planes. * This might be different from the first allocated byte * * Some decoders access areas outside 0,0 - width,height...
1, Are samples & lines actually indexed from zero? I ask because, if so, then shouldn't the extents should be 0,0 - (width-1),(height-1)? -- the descrepancy makes me unsure how to interpret what I read. 2, Are the width & height indexes in bytes or samples? If bytes, how are 8-bit v. 10-bit v. 12-bit pixel formats handled at the index generation end?
