Hi postfs1
I've had a look at the link you were good enough to provided and found this.
"2.3.1.2.1.2 S3 cards
S3 Savage3D's should work fine, but for Savage4, use XFree86 version 4.0.3 or greater (in case of image problems, try 16bpp). As for S3 Virge.. there is xv support, but the card itself is very slow, so you better sell it."
The trouble is I don't know if my card is "3D" and don't know how to try 16bpp. Is this something that can be set up by editing an mplayer file?
Thanks for your help.
Ken.

Hi charlie6
Have just tried converting from .mp4 to .avi. However, I find the video is a bit pixelated and is still out of sync with the sound. Oh well it was worth a try.
Thanks,
Ken.

all the .mp4 or .m4v , .flv or .avi are just container files the the encoding inside can all be the same, so the type of file doesnt really matter much.

Hi All
The previous post is perhaps an explanation of another thing that made me wonder about these .mp4 files produced by the iPhone4 as I have earlier mp4 files which work OK on mplayer. I should have said that I also tried 666philb's idea in the first post but It did not seem to make any difference.
Regards,
Ken.

I tested one publicly accessible .MP4 file and MPLayer was good at this experiment.

Hi postfs1
I made the changes you suggested i.e.
Audio from default to alsa.
Video from xv to x11.
Unfortunately video and audio still out of sync. However, I think if I click on an mp4 file I am using gmplayer rather than mplayer which I am using when running from a terminal. I'm not sure how much difference using the gui makes but I guess it slows things down a bit.
Thanks,
Ken.

Hi,
here running under Xorg X11 without extra video/audio card (just the intel on board devices);
the following mplayers command line code runs a/c sync nice on .avi files(*):
| Quote: | #!/bin/sh
exec mplayer -vo x11 -framedrop -autosync 30 -nocache "$@" |
(*)files converted from .mp4 to .avi using ffmpeg converter.
notes:
- the above code does not solve the a/v sync on .mp4 files.
- i believe the -framedrop option to be unnecessary.
best regards, charlie

************************************************
**** Your system is too SLOW to play this! ****
************************************************
Possible reasons, problems, workarounds:
- Most common: broken/buggy _audio_ driver
- Try -ao sdl or use the OSS emulation of ALSA.
- Experiment with different values for -autosync, 30 is a good start.
- Slow video output
- Try a different -vo driver (-vo help for a list) or try -framedrop!
- Slow CPU
- Don't try to play a big DVD/DivX on a slow CPU! Try some of the lavdopts,
e.g. -vfm ffmpeg -lavdopts lowres=1:fast:skiploopfilter=all.
- Broken file
- Try various combinations of -nobps -ni -forceidx -mc 0.
- Slow media (NFS/SMB mounts, DVD, VCD etc)
- Try -cache 8192.
- Are you using -cache to play a non-interleaved AVI file?
- Try -nocache.
Read DOCS/HTML/en/video.html for tuning/speedup tips.
If none of this helps you, read DOCS/HTML/en/bugreports.html.
Exiting... (End of file)

| Code: |
mplayer -quiet -vo x11 -ao alsa -vfm ffmpeg -lavdopts lowres=0:fast:skiploopfilter=all -cache 8192 /folder/Video.mp4

If MAN PAGE for MPLAYER is available:
man mplayer|grep --before-context=68 --after-context=50 lowres
man mplayer|grep --before-context=2 --after-context=1 vfm

Hi,
@postfs1 ==> thanks for your posts !
i also get this working playing a mp4 file with good audio/video sync:
| Quote: | #!/bin/sh
exec mplayer -quiet -vo x11 -ao alsa -vf crop=1024:500:100:140,scale=640:352,harddup "$@" |

Hi postfs1,
your previous post...
| Code: | | mplayer -quiet -vo x11 -ao alsa -vfm ffmpeg -lavdopts lowres=0:fast:skiploopfilter=all -cache 8192 /folder/Video.mp4 |
Running that code again returned a audio/video out of sync of about 1sec (video too slow), together with a full screen display. As the dispay is full scren, I believe the video cpu needs to be too high.
Running here a PC with lean video/audio resources, without extra sound/video card, I tried to reduce the display size in order to reduce the video CPU needs.
I then found the code given in my above post: the display is not full size nor complete screen, but enough for the current needs).
Cheers,
Charlie
