[FFmpeg-devel] [PATCH 5/7] avcodec/texturedsp: Add separate TextureDSPEncContext

[Andreas Rheinhardt <andreas.rheinhardt@outlook.com>]

ff_texturedspenc_init() doesn't support most of the function types
supported for decoding; add a separate context containing only pointers
for the actually supported types.
