error building lsw - error: ‘CODEC_CAP_DR1’ undeclared

[hydra3333]

Hello. Anyone else seen any error similar to this whilst building lsw ? It worked a week or three ago.

I currently build lsw, based on good advice from rdp, as a part of building x264 32bit and 64bit which can input and output containers like .mpg and .mp4 directly.

appears to build with some minor patches
VFR-maniac/L-SMASH-Works#75

Looks like no one is home at https://github.com/VFR-maniac/L-SMASH-Works so there's an interim fork with the patch at https://github.com/hydra3333/L-SMASH-Works

As of 2018 Feb, there are one undefined variable each for AviUtl and VapourSynth. However I don't think you need to modify all involved files. Just need to modify a header file in each folder.
For your reference:
https://github.com/MaverickTse/lsw-build3/LSWAviUtl_input_buffer_padding_size_20180220.patch applies to LSW/common
while
https://github.com/MaverickTse/lsw-build3/blob/master/LSWVAP_CODEC_CAP_DR1.patch applies to /LSW/VapourSynth

Sooner or later LSW is going to break completely if unmaintained, as there are already loads of deprecation warnings during build.
