mencoder not working? use FFMPEG INSTEAD! :)

**mersh** · 06-26-2007, 02:50 PM

Hello:

This is not a problem with the script, but rather my setup. When I upload an mpg (one I successfully uploaded to your vshare demo site) everything SEEMS to go fine. The mpeg is uploaded, there's a thumbnail for the file, but no flv file is actually placed in the flvideo folder. The uploaded movie itself appears in the video folder, but no corresponding FLV file - although the data for the file is there, including run time...

flvtool2 seems to be installed properly and working,
so does ffmpeg, and ffmpeg-php http://TheWall.net/phpinfo.php

FLV files that are uploaded work fine.

Here's an example of one that is not working:
http://www.thewall.net/view/2/test/

There's a thumbnail, and it THINKS the flv file is there, but it's not.

IF anyone has any ideas what I should be looking at, I'd really appreciate it.

It seems there is problem with mencoder installation on your server, check if your server can run the conversion command with out errors

/usr/local/bin/mencoder /home/thewall_net/public_html/video/7.mpg -o /home/thewall_net/public_html/flvideo/7.flv -of lavf -oac mp3lame -lameopts abr:br=56 -ovc lavc -lavcopts vcodec=flv:vbitrate=500:mbd=2:mv0:trell:v4mv:cbp:l ast_pred=3 -srate 22050 -lavfopts i_certify_that_my_video_stream_does_not_use_b_fram es

You can ask the server admin to run the command on SSH prompt or try running it from PHP script as described in

Here's what I tried while logged in as root (copied from debug.txt)

Code:

/usr/local/bin/mencoder /home/thewall_net/public_html/video/9.mpg -o /home/thewall_net/public_html/flvideo/9.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 -lavfopts i_certify_that_my_video_stream_does_not_use_b_frames

Here's the error I got:

Code:

MPlayer was compiled without libmp3lame support.
-lameopts is not an MEncoder option

Meanwhile, if I locate libmp3lame.so:

Code:

[root@clicker1 lame-3.97]# locate libmp3lame.so
/usr/lib/libmp3lame.so.0
/usr/local/lib/libmp3lame.so.0.0.0
/usr/local/lib/libmp3lame.so.0
/usr/local/lib/libmp3lame.so

AND when I ./configure mplayer, I see this:

Code:

Checking for libmp3lame (for mencoder) ... yes 
Checking for mencoder ... yes

Real head scratcher.....

Well, the problem with the above, was that I did not configure libmp3lame as shared.

I uninstalled both programs, then recompiled libmp3lame with shared enabled, made and installed, did same with mplayer (for mencoder)

Now it does something more than it did before, but not much.

I get a zero-byte flv file.

Here's the command line feedback:

It looks to me like it thinks it did the job...

if any ideas, would be thankful.
I've tried this with wmv, mov, and mpg, same results. I get a thumbnail of any of them, but a zero-byte flv file.

thanks for any help that might find it's way here :)

I don't know why it is not working for you. You can ask in mplayer mailing list to find a solution or use ffmpeg for converting video.

Yah, that's a good idea. I did sign up on their mailing list and will send in the question.

How would I tell the script to use ffmepg?

Admin, which is better? $cmd_mencoder or $cmd_ffmpeg

Spun2u, I've heard that mencoder does better, but this sure works fine for me. Some day I'll get mencoder working again, but this works just dandy.

Thanks again admin.
