rw_timeout -rw_timeout <int64> ED........ Timeout for IO operations (in microseconds) (from 0 to I64_MAX) (default 0) This can be used when you downloading segment or m3u8 file, the http response too long time. -m3u8_hold_counters <int> .D........ Maximum number of times requests when the m3u8 file not be refresh (from 0 to INT_MAX) (default 1000) this can be used when you can success download m3u8 but the m3u8 always refresh without new
