43c417ac1a avcodec/nvenc: fix hw accelerated transcode with bframes 
hw accelerated transcode (h264_cuvid -> h264_nvenc with -hwaccel cuvid) was
broken after the filtergraph initialization was changed to intialize decoder
first followed by encoder (commit af1761f7b5b1b72197dc40934953b775c2d951cc).
During initialzing encoder with bframes, local buffers are allocated
internally in encoder which fails since no cuda context is available. Now
pushing the correct cuda context before encoder initialization fixes the issue.
Also adding push/pop cuda ctx during create/destroy/map/unmap resources and
destroy encoder session.

AVCodecContext::refs is used to control the DPB size to be used by the

libavcodec/options_table.h is 1.

This patch sets AVCodecContext::refs to 0 for h264_nvenc and hevc_nvenc in
order to let the driver take the decision of the correct DPB size to use in
all cases.

220b24c7c9 lavc: remove libschroedinger encoding and decoding wrappers 
The library has stopped being developed and Debian has removed it
from its repositories citing security issues.
The native Dirac decoder supports everything the library has and basic
encoding support is still provided via the native vc2 (Dirac Pro, intra
only version of Dirac) encoder. Hence, there's no reason to still support
linking to the library and potentially leading users into security issues.
