Convert your videos to 3gp format

[lordkur]

I just did a couple of things to get my own videos on 3gp format so I can watch them on my cellphone !!!.


1- Install ffmpeg

Code: Select all

 USE='amr encode imlib v4l x264' emerge -v /usr/portage/media-video/ffmpeg/ffmpeg-0.4.9_p20070616-r2.ebuild  

2- Check if the libamr_nb and libamr_nw flags are available after install

Code: Select all

  ffmpeg -formats |grep amr

 DEA    libamr_nb
 DEA    libamr_wb
 

If you dont see those babies (libamr_nb and libamr_wb) there is something wrong

3- I just made a little script to try to make easier the job

Code: Select all

#!/bin/bash
#nokia-encoder.sh file
filein=$1
fileout=$2

#Check ffmpeg's compilation flags before using this script

ffmpeg -i "${filein}" -f 3gp -vcodec h263 -qmin 3 -qmax 5 -b 120 -acodec libamr_nb -ar 8000 -ab 10.2k -ac 1 -s 128x96 "${fileout}.3gp"

Usage:

Code: Select all

./nokia-encoder.sh Filein.avi Fileout.3gp 

It would be enough, enjoy!!!

Here is same script basically but for my Sony Ericsson k700i, posting here incase I loose my script again :
You get roughly 1 minute per MB with these settings, slightly better, your standard 20-22min series episode takes around 15MB.

Code: Select all

#!/bin/sh
# File : to3gp.sh script for Sony Ericsson with screensize 176x144 (such as k700i).
# Usage : to3gp.sh filename.avi
# Generates a .3gp file with same name as the .avi

FILE=$1
shift

rm -f "$FILE".3gp
ffmpeg \
    -i "$FILE" \
    -qmin 5 \
    -qmax 8 \
    -ar 8000 \
    -ac 1 \
    -acodec libamr_nb \
    -vcodec h263 \
    -s 176x144 \
    -r 12 \
    -b 120 \
    -ab 12200 \
    "$FILE".3gp

How to use this script with my Motorola z6, my screen is 240x320, and the h263 not support this size.

thanks

Thanks a lot for the tip

I've made a little script for my girlfriend, so she can easly convert video for her SE k750i. Also used h263 for video as mentioned before. The script also uses mplayer/mencoder before ffmpeg and (thanks to that) it supports more codecs.

There's also a little "TODO", but I don't know when it would be done. (-;

thanks

for the z6 you could use mp4 instead of 3gp, more quality for sure
