Package: mpv Version: 0.29.1-1 Severity: important Dear Maintainer,
Mpv takes around 2 to 3 seconds to startup even only run --help command without running any video. This only happens in Debian 10. In Debian 9 and Debian 8, mplayer (predecessor of mpv) runs in less than 1 second. when check with strace, we found out that each of the library loaded by mpv, it will do multiple llseek and read at same location. Sometimes it loads up to 5 or 6 times at same location. Mpv has many libraries and this causes the slowness of startup of mpv. Example of strace as below: openat(AT_FDCWD, "/usr/lib/arm-linux-gnueabi/libsndio.so.7.0", O_RDONLY|O_LARGEFILE|O_CLOEXEC) = 3 read(3, "\177ELF\1\1\1\0\0\0\0\0\0\0\0\0\3\0(\0\1\0\0\0\330!\0\0004\0\0\0"..., 512) = 512 _llseek(3, 49656, [49656], SEEK_SET) = 0 read(3, "\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0"..., 1000) = 1000 _llseek(3, 49328, [49328], SEEK_SET) = 0 read(3, "A(\0\0\0aeabi\0\1\36\0\0\0\0055TE\0\6\4\10\1\t\1\22\4\24\1\25"..., 41) = 41 _llseek(3, 49656, [49656], SEEK_SET) = 0 read(3, "\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0"..., 1000) = 1000 _llseek(3, 49328, [49328], SEEK_SET) = 0 read(3, "A(\0\0\0aeabi\0\1\36\0\0\0\0055TE\0\6\4\10\1\t\1\22\4\24\1\25"..., 41) = 41 _llseek(3, 49656, [49656], SEEK_SET) = 0 read(3, "\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0"..., 1000) = 1000 _llseek(3, 49328, [49328], SEEK_SET) = 0 read(3, "A(\0\0\0aeabi\0\1\36\0\0\0\0055TE\0\6\4\10\1\t\1\22\4\24\1\25"..., 41) = 41 _llseek(3, 49656, [49656], SEEK_SET) = 0 read(3, "\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0"..., 1000) = 1000 _llseek(3, 49328, [49328], SEEK_SET) = 0 read(3, "A(\0\0\0aeabi\0\1\36\0\0\0\0055TE\0\6\4\10\1\t\1\22\4\24\1\25"..., 41) = 41 _llseek(3, 49656, [49656], SEEK_SET) = 0 read(3, "\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0"..., 1000) = 1000 _llseek(3, 49328, [49328], SEEK_SET) = 0 read(3, "A(\0\0\0aeabi\0\1\36\0\0\0\0055TE\0\6\4\10\1\t\1\22\4\24\1\25"..., 41) = 41 _llseek(3, 49656, [49656], SEEK_SET) = 0 read(3, "\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0"..., 1000) = 1000 _llseek(3, 49328, [49328], SEEK_SET) = 0 read(3, "A(\0\0\0aeabi\0\1\36\0\0\0\0055TE\0\6\4\10\1\t\1\22\4\24\1\25"..., 41) = 41 In fact, we checked and found out that running other applications in Debian10 also has this issue. Debian 9 and Debian 8 does not have the same issue. Please help.
