MPC-HC(x64), AvsPmod too, can play the scripts.
When playing FFMS2("file_name.m2ts", colorspace = "yuv420p10") there is a normal 3640x2160 picture.
When playing FRIMSource(codec="h265", filename="file_name.m2ts", cache=1, num_frames=240) there is no picture.
with FRIMSource(codec="h265", filename="file_name.m2ts", cache=1, num_frames=240, container="ts")
there is the Error message above when I've tried .mkv file.
but FRIMSource(codec="h265", filename="file_name.h265", cache=1, num_frames=240) plays and V: rawvideo, yuv420p, 3840x2140
