Mathieu Duponchelle	a7180e3995	libcaption: fix bit set on indent preambles ... style preambles look like: |P|0|0|1|C|0|ROW| |P|1|N|0|STYLE|U| and column preambles look like: |P|0|0|1|C|0|ROW| |P|1|N|1|CURSR|U| Both preambles go through eia608_row_pramble(), the value they pass as the x parameter is supposed to hold 4 bits, either 0|STYLE or 1|CURSR This value then gets bit-shifted by 1 and or'd in the second byte. The value is also and' with 0x1E to ensure it can't leak into the upper bits. The previous code resulted in x being a 5-bit value, 0x10 (0b10000). This resulted in outputting a style preamble, as 0x10 << 1 & 0x1E is 0b00000. When the indent was 0 (the usual case), this went undetected, but with any other value it resulted in no indent being applied, but the text getting colored or italicized. This patch fixes x to have the correct value of 0x8 | indent.	2021-01-19 16:40:00 +01:00
