Enable other WMV decoders in ffmpeg
There's a ranked map that uses a WMV3 video, and WMV3 isn't enabled in the custom ffmpeg build, so currently the video doesn't play in osu!lazer

wmv3 would need to be enabled, and maybe wmv1 as well for good measure, in case other videos exist that use that codec.
If it's just one ranked beatmap then converting the video may be in our best interest rather than supporting edge-case codecs.
Joehuu mentioned a discussion post, which contains another map in wmv format https://osu.ppy.sh/b/1476582
Daisuke, possibly is strangest case, for me, since it uses .avi format with wmv3 codec (possibly, because BMS/LR2 still uses wmv to show video) here's it's mediainfo: https://gist.github.com/tadatomix/7587e49d0a8cba9ecffb4b4667c62fbc
edge-case codecs.
I wouldn't say the WMV family is an edge case codec. It was one of the main video codecs around the time when osu! was first released, and Windows Movie Maker wouldn't export H.264 by default until 2012. So there might be an unknown number of WMV videos out there.
I want to agree with you, yet so majority of ranked maps at that time preferred xvid/divx codec, actually. Iirc lazer has no issues with it
Example: First ranked map with a video Ken Hirai - Pop Star has a Divx 5 encoded video (See: https://gist.github.com/tadatomix/f822a92e847230171a4984a5fcb9a46b)
Yes, all flavors of MPEG-4 are enabled, not sure why only wmv2 is enabled and not 1 and 3.
This one https://osu.ppy.sh/b/428 seems to be broken both in stable and lazer due to using mpeg1, yet so I don't know if this should be added to framework as well.
