avcodec/xbmenc: xbm Lower memory use Two minor memory improvements. First bug reduces memory needed to about 6/7 the needed amount, which allows you to host almost 7 pictures in the same memory needed for 6 Second is a recalculation of the total additional memory for headers etc. size = avctx->height x (linesize * 6 + 1) + (31+32+38+4+1) Subject: [PATCH 2/3] avcodec/xbmenc: xbm Lower memory use Small 6/7th size memory reduction. size = avctx->height x (linesize * 6 + 1) + (31+32+38+4+1) Signed-off-by: Joe Da Silva <digi...@joescat.com> > http://git.videolan.org/gitweb.cgi/ffmpeg.git/?a=commit;h=cb70e1921aeda4df11ad77ee550e7bdcdca2b834 --- libavcodec/xbmenc.c | 4 ++-- 1 file changed, 2 insertions(+), 2 deletions(-) diff --git a/libavcodec/xbmenc.c b/libavcodec/xbmenc.c index 3fc0e3185a..193ced652a 100644 --- a/libavcodec/xbmenc.c +++ b/libavcodec/xbmenc.c @@ -32,7 +32,7 @@ static int xbm_encode_frame(AVCodecContext *avctx, AVPacket *pkt, linesize = (avctx->width + 7) / 8; commas = avctx->height * linesize; - size = avctx->height * (linesize * 7 + 2) + 109; + size = avctx->height * (linesize * 6 + 1) + 106; if ((ret = ff_alloc_packet2(avctx, pkt, size, 0)) < 0) return ret; @@ -41,7 +41,7 @@ static int xbm_encode_frame(AVCodecContext *avctx, AVPacket *pkt, buf += snprintf(buf, 32, "#define image_width %u\n", avctx->width); buf += snprintf(buf, 33, "#define image_height %u\n", avctx->height); - buf += snprintf(buf, 40, "static unsigned char image_bits[] = {\n"); + buf += snprintf(buf, 39, "static unsigned char image_bits[] = {\n"); for (i = 0; i < avctx->height; i++) { for (j = 0; j < linesize; j++) { buf += snprintf(buf, 6, " 0x%02X", ff_reverse[*ptr++]); _______________________________________________ ffmpeg-cvslog mailing list ffmpeg-cvslog@ffmpeg.org https://ffmpeg.org/mailman/listinfo/ffmpeg-cvslog To unsubscribe, visit link above, or email ffmpeg-cvslog-requ...@ffmpeg.org with subject "unsubscribe".
