From b25514a43f8780a13de5f09cb45c6046a60f4447 Mon Sep 17 00:00:00 2001 From: Xiaohui Sun Date: Tue, 3 Apr 2007 06:40:21 +0000 Subject: Changed the rle encoder a little and made it more universal. Not only the repeated byte is calculated as (count ^ xor) + add but also the raw encoding lenth byte is calculated as that too patch by Xiaohui Sun sunxiaohui dsp ac cn Originally committed as revision 8602 to svn://svn.ffmpeg.org/ffmpeg/trunk --- libavcodec/rle.h | 6 ++++-- 1 file changed, 4 insertions(+), 2 deletions(-) (limited to 'libavcodec/rle.h') diff --git a/libavcodec/rle.h b/libavcodec/rle.h index 5da09f2731..8ec3996810 100644 --- a/libavcodec/rle.h +++ b/libavcodec/rle.h @@ -23,7 +23,8 @@ #define RLE_H /** - * RLE compress the row, with maximum size of out_size.
