Avi and mpeg work with mplayer. Are any other file types currently supported?

mplayer uses FFMPEG, so the answer is "lots"

See: http://ffmpeg.mplayerhq.hu/ffmpeg-doc.html#SEC16

Hmm, did not know that. I don't see any settings for enabling access to it. Maybe garage account is needed to be able to edit wiki pages? Or maybe even project membership, don't know.

On the benchmarking, I realised that my results are pretty worthless. I don't think I understand what's going on, nor what to do to get meaningful results. The results I reported earlier in this thread are just numbers that don't mean what I thought they meant - 60s clips that take 60.5s to process doesn't mean that they play smoothly - in fact in this case playback was VERY jumpy.
If you use -benchmark and -nosound options, video will be played at maximum speed possible, so if you get 30 seconds for a 60 seconds video clip, that means mplayer takes 50% of resources for decoding and displaying video. If you add -vo null option, the video is only decoded without even being displayed (minus color conversion and flushing image to screen). So we can get insights about what parts of program take the most time.

I'm a programmer, and a couple of my skills are UNIX, Perl and Python scripting, so I'm willing to do any leg-work you can direct my way - just let me know what commands to run, and I'll run them on videos of varying size, FPS, ABR and VBR.
If you (or somebody else) could have a look and try making .deb package for mplayer, that would be great

I think that is work that will have to be made at some point anyway and delivering the deb making scripts to serge would help him out at some point and help us all immediately. Especially integration and means of registering of google video would be great (is mplayer able to playback youtube?). Does anyone know, if there would be a need for a plugin for opera to be able to launch google videos from web pages?
I would prefer a plain .deb for mplayer only (nonintrusive and guaranteed not to break user's system) and another one for opera and probably file manager integration

Third, I am not sure about how mencoder has been coded, but it might make sense to drop some seemingly unnecessary codeks from the pack to drop the filesize a bit.
Maybe, though it is not the highest priority now. I also tried compiling with -Os instead of -O4, but the size difference is not so noticeable and decoding video gets slower.

By the way, maybe using profile guided optimizations can improve performance somewhat (-fprofile-generate and -fprofile-use gcc options), but they seem to be not supported in codesourcery toolchain (when used with -c option).

Hi,

i do not own a N770 yet but it is on his way and will arrive tomorrow morning :-)

I was very suprised to hear that you can use mplayer on it :-)

Now my question:
On my Laptop i use mplayer with the esd-sound output to stream the Sound of the Videos i watch to another Laptop that is connected to the Speakers.
I guess the answer is no, but is this maybe even possible on the N770?

Regards
Schmolch

MPlayer interrupted by signal 11 in module: preinit_libvo
- MPlayer crashed by bad usage of CPU/FPU/RAM.
Recompile MPlayer with --enable-debug and make a 'gdb' backtrace and
disassembly. Details in DOCS/HTML/en/bugreports_what.html#bugreports_c rash.
- MPlayer crashed. This shouldn't happen.
It can be a bug in the MPlayer code _or_ in your drivers _or_ in your
gcc version. If you think it's MPlayer's fault, please read
DOCS/HTML/en/bugreports.html and follow the instructions there. We can 't and
won't help unless you provide this information when reporting a possib le bug.

I found a kmplayer .deb and installed it but it doesn't perform very well and you cant configure it anyway like you could with mplayer from console.

A link to the page where you can get MPlayer binary for Nokia 770 is in my signature. It is not yet packaged in .deb for a number of reasons. The most important of them is that I don't think that MPlayer is end user ready right now and don't feel like supporting it, sorry. My intention from the very beginning was to provide some starting ground and handle this project over to somebody else who has more spare time to work on it. I'm not going to abandon it though as there are still some interesting ideas to try

Installed mplayer on my Nokia 770 and am able to stream Internet wmv feeds/streams such as DL.TV transcoded to mpeg1 by TVersity (unlike the issues I was having with the Nokia's built in Video Player which would not stream mpeg1 Video successfully with play-buffer-play-buffer issues)

Here is my ongoing Nokia 770 Video streaming thread in Tversity forumshttp://s90264353.onlinehome.us/phpBB...c6dd9b6a#11485

I am looking forward to the mplayer port being packaged for general Nokia 770 user usage with an option to integrate with the Opera web browser without the need to be root etc.

Great work Serge

I've uploaded a new version of my command line encoder which supports an "mplayer" prefix for 400x240 video.

It plays back much better than the "best" preset for the built-in video player with no noticeable tearing, even at 25fps.

Tested using the command:

Code:
mplayer -fs -vo x11 -ao gst -ac dspmp3
No frame drops with this preset :-)

Any questions, just give me a shout.

Cheers,

Andrew

I cannot get the script to run in Win32 ('Get a Faile to get movie info'). What is the gist of the settings you found to be optimal for mplayer. I tried to see what you are using in the script but I still get tearing on my test so I must be missing something.
