Video from HDMI recorder -- 22GB, 4h long, H265.

Opened from .avs file via BSSource. Creating the cache file took so long.

Well, there are file formats which are hard to parse, because it requires sequential reading across the whole file, due to the lack of a header which contains a lot of useful information (like a list of GOP start positions) right in the beginning. TransportStreams, as used in Digital Broadcast, are such a case. Raw H.264/H.265 video streams too, they would strictly even require parsing bit by bit, fortunately most are conveniently aligned at least at byte boundaries.

Yes, but ffms2 or Libav do it much faster, so there is room for improvement.

Ah, okay; I guess BestSource needs its own thread then, I did not notice you mean "BS in contrast to FFMS2 and LSW".

So to be in line with the topic, I will write that ffms2 does not want to support long paths -- with 219 characters (including national ones) I get:

Code:
[in#0 @ 000002752ddb7a00] Error opening input: Unknown error occurred
Error opening input file testXXX.avs.
Error opening input files: Unknown error occurred
