Played with MPlayer controls and now I'm in trouble

druuna · 01-21-2007, 08:52 AM

Hi,

The last three threads seem to confirm my first reply: The file itself is the problem.

I've never created a flv file before myself, but what I read about it tells me that one needs to be precise, especially when audio syncing is concerned. It also seems to matter if you stream flv's or embed them in swf's.

You mention that windows (media player/mplayer/something else??) doesn't have the sync problem. It could be that the player used is more forgiving then mplayer (the linux one), it could also be that you need to include a better/different program that mplayer uses (ffmpeg comes to mind).

The link you provided that you used to install mplayer does not mention the dependencies and other optional software that mplayer can pick up during a build from source.

BTW: What happens if you create a flv file with mencoder, is the sync still off or is it correct.

Hi,

I really don't think that something is wrong with the file because MPlayer played the video perfectly before I pressed the + and - signs. After closing the WIndow, instead of forgetting the changes, it seems to have recorded them.

Also, on Windows, I used FLVPlayer 1.3.3

Yes, I'm using ffmpeg codecs.

Yes, but I downloaded the all-codecs package and extracted it. I can choose any codec that I want. But all of them give the same problem.

Besides, MPlayer has played the files properly before. If it played it properly before, it should be able to play them properly again right?

I'm getting a small error at the ending on entering:

mencoder Self\ Defense.flv -o movie.avi -ovc lavc -oac lavc

Code:

[mp2 @ 0x86e4f8c]bitrate 224 is not allowed in mp2
Couldn't open codec mp2, br=224.

We seem to be going in circles here

This seems to be a dedicated flv player, I do expect it to play flv's the way they are ment to.

I was not talking about the codec files package, but about the programs mplayer can (and will) use. These need to be present before you build mplayer from source (libvorbis-1.1.1 and XviD-1.0.3 are just 2 of those)

Take a look here to get an idea: [LFS] Mplayer install page

If nothing has changed on your box, your assumption is correct.

Quote:

mencoder Self\ Defense.flv -o movie.avi -ovc lavc -oac lavc

Although I never created a flv file, I do know that the command used is incorrect. The infile you use is a flv file.

The following comes from the mplayer helpfile and is used for creating a Macromedia Flash video suitable for playback in a web browser with the Macromedia Flash plugin:

mencoder input.avi -o output.flv -of lavf \
-oac mp3lame -lameopts abr:br=56 -srate 22050 -ovc lavc \
-lavcopts vcodec=flv:vbitrate=500:mbd=2:mv0:trell:v4mv:cbp:last_pred=3

Maybe the powermanagement of your box is the problem (although this is most common when using mplayer on a laptop). Try using the -nortc option while playing the file.

Can you post the output of mplayer -v infile.flv? Maybe there's a hint there about the problem.

Yes. The files you mentioned were present before compliling.

Yes, I know that. I wanted to convert the .flv file into an avi file to see if there could be any delay present in the output file. The input file was an flv file originally. I had taken it from YouTube.

Ok, but it is very large.

Hi,

Output looks ok (one small thing, but that isn't the issue atm: mplayer falls back to the build in codecs file. copy the codecs.conf file to your ~/.mplayer directory to solve this).

If I'm correct you have to create a <filename>.flv.conf file as well as the <filename>.flv file. Did you try recreating the <filename>.flv.conf file?

Did the -nortc option do anything for you?

Ok, I'm out of ideas........

Ok, I fixed this.

I don't know about this. I usually run the files by typing:
mplayer file.flv, and the file runs. I typed: locate *.flv.conf and I got no results. Would you please elaborate on the .flv.conf file?

Quote:

I typed mplayer -nortc file.flv and I still got the same result.

Thanks.

P.S. What are subtitles in MPlayer?

Besides what I've read in the last days I don't know anything about creating flv files (like I stated before).

I did read that audio/video sync problems could be related to the flv.conf file, and recreating this flv.conf file (you did say you created the flv file yourself) could solve your problem. The -nortc option was another hint, but related to laptops/power management.

The flv.conf file is also mentioned in the mplayer -v output, and seems to be found:
get_path('Self Defense.flv.conf') -> '/home/thezealicon/.mplayer/Self Defense.flv.conf'

BTW: locate only works if the database is fresh (run updatedb to update the database).

Like any good video player, mplayer can handle (external) subtitle files. These external files need to be present to use them. Files with a srt extension (just one of the many formats) are an example. See the manual page for details.

Well, I didn't create the file. I just downloaded it. I ran updateb, but it still does not locate any .flv.conf file.

I find a similar message for other flv files.

Do you think that this could be a bug in MPlayer? I don't know if anyone else faces the same problem. If you had an flv file, you could try it out yourself. Here's how I got one. I watched a minute long video on YouTube. I sorted my browser(firefox) cache by size and the largest file was the video file. I renamed it to .flv (mv file fil.flv) and then played it with MPlayer. ALl my flv files are from YouTube.

gregorian · 01-26-2007, 08:05 AM

Well, I just noticed that if you click on the "empty" space of the playbar in gmplayer, instead of jumping to that part of the flv video, it synchronises the sound for a few seconds and then its back to normal(as in non-synchronised).
