libavcodec/libvpxdec.c💯57: warning: passing argument 3 of 'av_image_copy' from incompatible pointer type
av_image_copy(picture->data, picture->linesize, img->planes,
libavutil/imgutils.h:116:6: note: expected 'const uint8_t **' but argument is of type 'unsigned char **'
void av_image_copy(uint8_t *dst_data[4], int dst_linesizes[4],
This avoids SIMD-optimized functions having to sign-extend their
line size argument manually to be able to do pointer arithmetic.
Also adjust parameter names to be "linesize" everywhere.
This avoids SIMD-optimized functions having to sign-extend their
stride argument manually to be able to do pointer arithmetic.
Also adjust parameter names to be "stride" everywhere.
The code currently reads the coded dimensions from the extradata, but
expects the display dimensions to be set by the caller, and does not
check that they are compatible (i.e. that the displayed size is smaller
than the coded size).
Make sure that when the display dimensions are set, they are also valid.
Fixes possible invalid memory access.

It is passed to the get_bits API, which requires buffers to be padded.
Fixes possible invalid reads.

height - me_y is the line from which we read, so it must be strictly
smaller than the frame height. Fixes possible invalid reads in corrupted
files.
Also, use a proper context for logging the error.

If we encounter an END element before anything is decoded, we would
return success even though the output frame has not been allocated,
which is invalid.
