Waouu, you made huge progress
On PC it should be feasible to use VLC. But on Mac, I've no idea, sorry.

Brilliant - thanks! (Yes, I live under a rock - I'd never heard of VLC).

I got it!!! (Took forever but )

It's streaming and I can see and hear it on the N800. Looks/sounds good.
Here's my setup:

I'm streaming with VLC for Mac.
Use the Streaming/Trancoding Wizard.

Select Stream to Network.
Select the movie source.
Select Http. (Leave the IP address box blank).
Set the video codec to mpeg 4, bit rate 512 (may need to go down to 256).
Set the audio codec to MP3, bit rate 64.
Choose the ASF encapsulation format.

On the N800, I'm playing it with Mplayer. For noobs like me, to get it to play, launch MPlayer (which will launch the GMPlauncher).

Enter the IP address of your host computer and port number in the PLAY line. (EG. http://<the IP address of the host machine>:8080/ (8080 is the default port number).

Click Play and enjoy!!!

Thanks so much!
Denise

I made an Ajax webapp with Rails that uses VLC via telnet to stream media from my Ubuntu box. It allows me to view movies and live-tv with my N800 using MPlayer. Settings I've used for VLC are:

#transcode{fps=25.0,width=400,height=240,vcodec=mp 4v,vb=768,scale=1,acodec=mp3,ab=128,channels=2}:st d{access=http,mux=asf,dst=192.168.0.3:1416/stream.avi}

Stream opens nicely with MPlayer and quality is enough for me and the playback is smooth.

Thanks - but you're waaay over my head! (Ajax, Ubuntu and Rails are not in my vocab yet )

Sounds like the settings are similar. I'm ripping my DVD's with Handbrake - MPEG 4, AAC, datarate 500 - and cropping the picture to the same size 400x240.

This way, I can take them with me or watch at home.

My next challenge is getting DVD's to stream - not working with the same settings ...

enjoy!

That website sounds cool. I'm experimenting with fuppes, which supports transcoding, but otherwise using vlc is exactly what I was thinking. I've had better luck from vlc using mpeg1, mpega, and mpeg1 container, though. Most of what I've downloaded works with the settings you show, but it seems nothing I ripped myself receives audio if I use mp3 as the audio codec.

Edit: Oh Now that I have fuppes built will all of the transcode libraries, I find it doesn't support video transcoding of any kind . You don't suppose you'd release your webpage source to the public so I could drop it in apache, do you

On startup, I have vlc open with the web interface only and preset for the proper transcoding. I also edited /usr/share/vlc/http/dialogs/browse such that "browse_lastdir" has a more preferable starting directory than "~".

The vlc command I use is
Code:
vlc --intf=http --sout '#transcode{vcodec=mp1v,vb=384,scale=0.75,acodec=mpga,ab=64,channels=2}:std{access=http,mux=mpeg1,dst=:1234}'
Now I can use the web browser on the N800 and connect to "http://mycomputer:8080" and choose a media file to stream. Once the stream has started, I can use KMplayer and load up "http://mycomputer:1234" to watch the stream.

I've found that a 700Kbps, 320x240, 15fps clip encoded with RealVideo 10 and 64Kbps stereo music high response plays back locally on my N800 fairly well. It briefly drops frames just after playback starts, but then seems to get up to speed and play the rest of the 60 second file well. Audio playback is good throughout.

Unfortunately, for on-demand streaming, I had to encode the same content with much lower settings: 225Kbps, 240x180, 15fps, RealVideo 10, and 32Kbps stereo music high response. It drops a few frames, but fewer than with local playback of the 700Kbps file.

I have not yet tried any MBR files. I'm curious to see if they work, and if so, which rate the N800 selects.

I've never encoded a 3GP file, and I suspect I'd need to upgrade to Helix Mobile Server 11 for good support for that format. I'll have to investigate that.
Hello, I understand that this an old thread, but I am facing similar problems as stated in the quoted post. Has anyone figured out how to improve sreaming performance of real video?

I am currently using licensed versions of the Helix server and producer, but I am unable to achieve appreciable peformance of on-demand streaming of videos (anything more than 200-220 kbps results in dropped frames.)

I heard a rumor somewhere that theres a configuration file somewhere on the device which can be edited to improve the performance (some code that limits the bitrate?)

Does anyone have any ideas on this?

p.s: I am using a bunch of N800s and N810s with OS2008 on them and the encoded videos are 320x240 , 30fps, rmvb.


p.s2: I had tried streaming quicktime videos using a Darwin streaming server. Strangely On-demand video works on the default media player (H.264), however it refuses to play locally (from the mem. card.) The problem of high bitrate streaming (>200kbps) is still persistent with the quicktime streaming.

Any comments on these issues will be really helpful.

Thank you.

Amazing stuff

Now that the new VLC version is (hopefully) right around the corner and if there is interest, I may release my streaming app soon. I have all the features I wanted now implemented, but I need to do some bug fixing and testing with the vlc build once it gets out. It works with all tablets and plays most videos/dvds with subtitles. Live-tv with epg-support is supported via vdr (if available) and it allows you to queue files to a transcode list and get them transcoded and transfered to device with few clicks.

Seeking and pausing also work so you don't have to start from the beginning if you don't finish a video.

It works with Linux, BSDs and OS X but Windows is not supported (at least for now).
