I know that AVCodecParser was lacking the typical public-private
demarkation, but you are actually not supposed to call these function
pointers directly. In fact, it is not publically documented at all what
AVCodecParser.split does.
Anyway, use the extract_extradata BSF. It is the intended replacement
for this feature. It is also what avformat_find_stream_info() uses to
extract extradata in case the container doesn't provide any.

Re: [FFmpeg-devel] [PATCH 81/87] avcodec: Move all AVCodecParser.split functions to remove_extradata_bsf
Hi all,
I know this happened quite some time ago, but we just noticed the
change.
This effectively disables the public API AVCodecParser.split for these
codecs. HandBrake uses this API to split out extradata for a few
codecs. Any chance we can bring these back? Otherwise, we will have to
replicate this code in HandBrake 😕️
