[vlc-devel] [PATCH 2/3] omxil: Avoid warnings about differences in signedness

[Martin Storsjö]

For omxil, the nal size has already been parsed out elsewhere, so
we don't need it returned here.

This fixes this warning:
omxil.c:926: warning: pointer targets in passing argument 7 of 'convert_sps_pps' differ in signedness
h264_nal.h:22: note: expected 'uint32_t *' but argument is of type 'int *'
---
An alternative fix would be to skip the previous patch and just add
a local uint32_t variable to store the result in, which then just would
be ignored.

Yet another alternative would be to change i_nal_size_length in the
omxil module to uint32_t, but that causes a cascade of other new
warnings instead, about comparsion between signed and unsigned.
