av_packet_add_side_data() already defines size as a size_t, so this makes it consistent across all side data functions. Signed-off-by: James Almer <jamrial@gmail.com> --- I could either add ifdeffery to every size argument used in av_packet_get_side_data() calls within the libraries, add an internal typedef that goes int -> size_t depending on FF_API_BUFFER_SIZE_T and use that, or just not bother with them right now and change them after the bump in the same commit that removes FF_API_BUFFER_SIZE_T. In this patch i went the ifdef route for ff_side_data_set_encoder_stats() and ff_side_data_set_prft(). doc/APIchanges | 4 ++-- libavcodec/avpacket.c | 28 ++++++++++++++++++++++++++++ libavcodec/packet.h | 4 ++++ 3 files changed, 34 insertions(+), 2 deletions(-)
