[FFmpeg-devel] [PATCH 0/2] avcodec: add realtime bitstream filter

The realtime bitstream filter is modeled exactly along the
realtime/arealtime filters, but works on bitstream level, allowing to use
them with the copy codec.
It can be considered a proof of concept, as ffmpeg offers the "-re" option
to achieve this, but:
- the "-re" option is not available in the libraries, and has to be
remodeled by other applications wishing to achieve that effect;
- the second patch in this series allows to scale the speed, which the "-re"
option does not offer.
Since the core implementation is a blatant copy of f_realtime, its author
Nicolas is credited here.
