problem with mencoder


Hi all,

I have installed vshare in my linux system and also configured the linux server as described in http://labs.buyscripts.in/projects/v...i/Server_Setup

then i uploaded one sample video to the directory /public_html/videos/templates_c/import/

and imported the video from "Video Processing" section

and when i try to convert the imported it shows me the following screen

"""
STARTING VIDEO CONVERSION (process_queue.id = 25)

File: /home/hijohn/public_html/videos/video/031.mp4

####################################################

SELECT * FROM `video` WHERE `VID`=24

####################################################

Video id: 24

Find video duration - START

Duration (ffmpeg-php): 49

DURATION: 00:49

Create Thumbnail - START

Create Thumbnail with ffmpeg-php - END

CONVERT COMMAND: /usr/bin/mencoder '/home/hijohn/public_html/videos/video/031.mp4' -o /home/hijohn/public_html/videos/flvideo/12664288231538911220.flv -of lavf -oac mp3lame -lameopts abr:br=56 -ovc lavc -lavcopts vcodec=flv:vbitrate=500:mbd=2:mv0:trell:v4mv:cbp:last_pred=3 -srate 22050 -ofps 24 -vf harddup

####################################################

####################################################

Return value:
Video Conversion Finished

Back
"""

and when i click back it shows "Convert Error"

i also checked that the file /home/hijohn/public_html/videos/flvideo/12664288231538911220.flv doesnt exist

then i tried the same command in Shell it converts the video successfully without error. And the file 12664288231538911220.flv also exist on the specified folder.

Could you tell me why it is not hapening from the web.

Thank you

Regards
sudhir Maharjan

The first thing that springs to mind is that the userID as which
apache is running doesn't have the right permissions on that dir.

Ummm ...

Check
Code:
$ ps -ef | grep http
root      3204     1  0 16:39 ?        00:00:00 /usr/sbin/httpd -k start
apache    3222  3204  0 16:39 ?        00:00:00 /usr/sbin/httpd -k start
apache    3223  3204  0 16:39 ?        00:00:00 /usr/sbin/httpd -k start
apache    3224  3204  0 16:39 ?        00:00:00 /usr/sbin/httpd -k start
apache    3225  3204  0 16:39 ?        00:00:00 /usr/sbin/httpd -k start
apache    3226  3204  0 16:39 ?        00:00:00 /usr/sbin/httpd -k start
Which user is apache running as?
For me it's apache. Now, assuming you have root access to that machine
you're working with, try:
Code:
sudo -u <apache user> touch /home/hijohn/public_html/videos/flvideo/some_random_filename
What message or result do you get?



Cheers,
Tink

The next thing to check will be whether 'nobody' is allowed to
read '/home/hijohn/public_html/videos/video/031.mp4' and allowed
to run mencoder ...

Code:
ls -l `which mencoder`
will tell us the owner, group, permissions for mencoder.
are you able to ssh in as <nobody> and run:
Code:
/usr/bin/mencoder '/home/hijohn/public_html/videos/video/031.mp4' -o /home/hijohn/public_html/videos/flvideo/12664288231538911220.flv -of lavf -oac mp3lame -lameopts abr:br=56 -ovc lavc -lavcopts vcodec=flv:vbitrate=500:mbd=2:mv0:trell:v4mv:cbp:last_pred=3 -srate 22050 -ofps 24 -vf harddup

with the command line

/usr/bin/mencoder '/home/hijohn/public_html/videos/video/031_2.mp4' -o /home/hijohn/public_html/videos/flvideo/12664288231538911220.flv -of lavf -oac mp3lame -lameopts abr:br=56 -ovc lavc -lavcopts vcodec=flv:vbitrate=500:mbd=2:mv0:trell:v4mv:cbp:last_pred=3 -srate 22050 -ofps 24 -vf harddup

it creates the file 12664288231538911220.flv

but with the following command the result is

sudo -u nobody /usr/bin/mencoder '/home/hijohn/public_html/videos/video/031_2.mp4' -o /home/hijohn/public_html/videos/flvideo/12664288231538911220.flv -of lavf -oac mp3lame -lameopts abr:br=56 -ovc lavc -lavcopts vcodec=flv:vbitrate=500:mbd=2:mv0:trell:v4mv:cbp:last_pred=3 -srate 22050 -ofps 24 -vf harddup

Did you REMOVE the output file after the first run?

If the answer is 'YES' I'd suggest running the sudo version
under the strace
Code:
sudo -u nobody strace -o /tmp/mencoder.dbg -vFf /usr/bin/mencoder '/home/hijohn/public_html/videos/video/031_2.mp4' -o /home/hijohn/public_html/videos/flvideo/12664288231538911220.flv -of lavf -oac mp3lame -lameopts abr:br=56 -ovc lavc -lavcopts vcodec=flv:vbitrate=500:mbd=2:mv0:trell:v4mv:cbp:last_pred=3 -srate 22050 -ofps 24 -vf harddup
