Given the recent changes to ff_cbs_delete_unit, it is no longer sensible to use a return value for ff_cbs_h264_delete_sei_message; instead, use asserts to ensure that the required conditions are met and remove the callers' checks for the return value. Also, document said conditions. An assert that is essentially equivalent to the one used in ff_cbs_delete_unit has been removed, too. Signed-off-by:Andreas Rheinhardt <andreas.rheinhardt@gmail.com>

ff_cbs_delete_unit never fails if the index of the unit to delete is valid, as it is with all current callers of the function. So just assert in ff_cbs_delete_unit that the index is valid and change the return value to void in order to remove the callers' checks for whether ff_cbs_delete_unit failed. Signed-off-by: -

This commit changes vp9_metadata to (a) use ff_bsf_get_packet_ref instead of ff_bsf_get_packet (thereby avoiding one malloc and free per filtered packet) and (b) to use only one packet structure at all, thereby avoiding a call to av_packet_copy_props. (b) has been made possible by the recent changes to ff_cbs_write_packet. Signed-off-by: -

If a new sequence display extension had to be added, this was up until now done at two places: One where a sequence display extension was initialized with default values and one where the actual sequence display extension was inserted into the fragment. This division of labour is unnecessary and pointless; it has been changed. Furthermore, if a sequence display extension has to be added, the earlier code set some fields to their default value twice. This has been changed, too. Signed-off-by:
