[FFmpeg-devel] Can a GetByteContext have a "sub" context?

Hello, Is it possible to have a "sub" context with a limited byte range for a super-context? i.e. I read 4 bytes from context c1, these are a length, c2 = GetByteContext_from(c1, len) ? Or is "GetByteContext(&c2, c1.buffer, len);" enough? Thanks! Manuel

vf_scale_d3d11.c does not instantiate the interface IDs that it uses (IID_ID3D11VideoDevice and IID_ID3D11VideoContext). Builds of avfilter for Windows configured such that no other source files instantiate these IIDs will result in missing symbol errors during linking. The fix is to include and
