Re: xvid mencoder

Я делаю так:

1 - определяю границы обрезания (необходимо в 95% случаев):
mencoder -dvd-device /dev/hdd \
dvd://1 -ss 630 \
-vf cropdetect=100 \
-ovc lavc -oac copy -o /dev/null

2 - использую script, который когда-то для этого написал:

#!/bin/bash

# making global variables

chapter=1
from="-dvd-device /dev/hdd dvd://$chapter"

brate=966
tocrop="704:544:10:16"
filter2="scale -zoom -xy 608 "
filter1="crop=${tocrop}"
ofname="American_story_X.avi"
START=0
END=6636

# descrybing the functions:

first-pass()
                        {
                        # the firts pass starts here
                        echo "starting first pass..." > coding.txt
                        date >> coding.txt
                        echo >> coding.txt

                         mencoder -mc 1 $from -vf ${filter1},${filter2} -ss $START -endpos $END \
                        -ovc xvid -xvidencopts vhq=4:bitrate=${brate}:pass=1:gmc:max_bframes=1 -sws 10 -ofps 23.976 \
                        -oac mp3lame \
                        -o /dev/null 2> /dev/null

Re: xvid mencoder

Спасибо!

Re: xvid mencoder

Незашто. Только вот опция "-ofps 23.976" у меня не реализуется =( На выходе всё те-же 29 с кусочком кадров. Никто не знает почему?

Re: xvid mencoder

правильно надо: -ofps 24000/1001
