Encodes are failing in 7.1 with error parsing options for output file, error opening output files

[John Hauer]

I am try to transcode from h.264 to h.265

The encode is failing with the following error on every .mkv file I try to transcode:

Stream type specified multiple times
Error parsing options for output file eureka_x265.mkv.
Error opening output files: Invalid argument

The exact command I am using, which works properly in 6.x and 7.0.x:

ffmpeg -v 9 -loglevel 99 -y -i eureka.mkv -c:v libx265 -pix_fmt yuv420p10le -preset medium -crf 22 -c:a libopus -mapping_family:a 255 -map 0 -disposition:s:s 0 -c:s copy eureka_x265.mkv

c:\Temp>ffmpeg -v 9 -loglevel 99 -y -i eureka.mkv -c:v libx265 -pix_fmt yuv420p10le -preset medium -crf 22 -c:a libopus -mapping_family:a 255 -map 0 -disposition:s:s 0 -c:s copy eureka_x265.mkv

I have also tried a build from ​https://github.com/BtbN/FFmpeg-Builds/releases that produces the same result

[Gyan]

The syntax for stream specifiers in disposition no longer requires the s, so what would earlier be -disposition:s:s:1 0 for the 2nd subtitle stream is now -disposition:s:1 0

[elenril]

no longer requires the s

Did it ever?
