From: Alan J. Pippin Date: Thu, 21 May 2009 20:07:35 +0000 (-0600) Subject: Renamed compress_vob_file method to encode_vob_file and moved to top of function... X-Git-Tag: 1_0~15 X-Git-Url: http://git.pippins.net/embedvideo/.git/static/images/%7Bedit%7D?a=commitdiff_plain;h=aacf74d70ad8d74b29fdffc4d5d9a98ae3485c11;p=rip_dvd%2F.git Renamed compress_vob_file method to encode_vob_file and moved to top of function list. Since this will probably be the most commonly changed section of code, moved it up! --- diff --git a/rip_dvd b/rip_dvd index 18ef460..1b3fec5 100755 --- a/rip_dvd +++ b/rip_dvd @@ -351,6 +351,194 @@ trap cleanup EXIT ############################################################################################## # processing functions ############################################################################################## + +# encode the vob file into a compressed file format +function encode_vob_file { + typeset -i found_profile=0 + + # XVID profile + if [ "$profile" == "xvid" ]; then + found_profile=1 + final_output_file="$dest/$dvdname.avi" + mencoder_general_opts="-quiet $lang_opts -passlogfile $passlogfile" + mencoder_output_opts="-ofps 30000/1001 -ffourcc DIVX" + mencoder_video_filter_opts="-vf pullup,softskip,hqdn3d=2:1:2$CROP$SCALE" + mencoder_video_encoder_opts="-ovc xvid -xvidencopts pass=%PASS" + video_encoder_opts[0]="bitrate=$target_bitrate" + video_encoder_opts[1]="threads=$mencoder_threads" + video_encoder_opts[2]="chroma_opt" + video_encoder_opts[3]="vhq=4" + video_encoder_opts[4]="bvhq=1" + video_encoder_opts[5]="quant_type=mpeg" + video_encoder_opts[6]="autoaspect" + for OPTS in "${video_encoder_opts[@]}"; do + mencoder_video_encoder_opts="$mencoder_video_encoder_opts:$OPTS" + done + + if [ $audio_2ch -eq 0 ]; then + # These options produce good 6 channel audio for linux and windows + mencoder_audio_opts="-oac copy" + # There are 3 different ways to specify 6 channel encoding.
