[Canola] Movie Encoding for Mplayer...
 

Since this is a video related question, and I did not know where to post this, I thought to give it a shot in the Canola forums since people are savvy enough for video.

I am trying to encode some movies so that they play via the mplayer w/o stutter.

I have tried the Media Converter 1.43, with no help. And recently I even tried Media Converter 2.03 which I believe is based on 1.43 but with x264 support. I have noticed, great stutter on portions of the movie where the bitrate is higher than usual.

Again I used profiles in both encoder that corresponds to a higher than avg quality, based on those application settings. I remember when I used to encode Planet Earth to watch on the Xbox 360 back before they introduce the avi/xvid codecs, I used to have similar problems, because I had to choose the correct VC1/WMV settings/profile so that the 360 could play it nicely, and it was mainly related to the bitrate on high traffic scenes where there are lot of movements going on.

Bottom line, I am running out of ideas for the tools to use based on the N800, and going to use my other tools (Total Video Converter, Super & PocketDivxEncoder), if anyone has done such tests and can give their 2c on this, I'd appreciate it.

Thanks,
Houman

Edit: Looks like I have been a bit too optimistic about n800 ability to play high bitrate movies even with mplayer and this article helps...

* Run a search in this forum
* Use Nokia Media Converter
* Use http://xoomer.alice.it/sepaolo/n800vc/
* Use http://mediaconverter.garage.maemo.o...Converter.html
* Use 400x240 resolution

Thanks a lot.

Re: Moving Encoding for Mplayer...
 

So I have a question, why is there so many different releases of Media Converter by Urho recommended by different people ?

There is :
Version 1.2: http://mediaconverter.garage.maemo.o...Converter.html
Version 1.43: https://garage.maemo.org/projects/mediaconverter/
Media Converter 2.03: http://www.audua.com/Media_Converter_2/index.html

Which one is the official version ? which one is the recommended version ?

Thanks
Houman

Re: Moving Encoding for Mplayer...
 

I believe Media Converter 2.03 is an enhanced version of 1.43 [better GUI too] (and 1.2 maybe an old one).

Re: Moving Encoding for Mplayer...
 

Yeah, makes sense what you say...

I am using this : http://xoomer.alice.it/sepaolo/n800vc/ Bundyo recommended, will see if it works out... I think it's most likely because of the resolution like he said. I thought the n800 could handle the max resolution video files, but it's unlikely at this point (which is okay).

Re: Moving Encoding for Mplayer...
 

Some people had success with bigger files, but full resolution is impossible with the current hardware.

Re: Moving Encoding for Mplayer...
 

I converted all those files with the other tool you mentioned, and they all play very nicely.

Thanks again.

Re: Moving Encoding for Mplayer...
 

Best bets for media encoding are, IMHO:

Windows: Nokia Internet Tablet Video Converter
Linux/BSD et al: tablet-encode
Mac OS X: tablet-encode or Urho Kontorri's Media Converter

I'm biased, of course. YMMV.

Re: Moving Encoding for Mplayer...
 

I've personally found the best results are with tablet-encode, all other converters for mobile devices including Nokia Internet Tablet Video Converter haven't had quite as good results IMO.

Re: Moving Encoding for Mplayer...
 

I noticed that when I play some movies with Canola, they do stutter and skip (not all the time, but like every 2-3 minutes), but this does not happen when I play directly the movies in mplayer. I do know that Canola is using mplayer... is there any settings I could fiddle with ?

I am using both latest version of mplayer & canola2

Thanks

Re: Moving Encoding for Mplayer...
 

Houman : you can always refer to the previous posts (searching by Canola mplayer performance ) for example :) so you maybe find answers faster ... unfortunately I cannot answer as I would like (instantly) .. (just a tip don't mean to be rude )

Then.. the answer is simple : mplayer can indeed play better than Canola with Mplayer. Why? the embedded mplayer mode is different in performance. So.. to use with Canola please encode the movies in a slightly lower quality codec to be able to play it nicely. We are trying to solve this with a new media framework (libXine) but there's no expectations on how much time it would take.

Cheers!

Re: Moving Encoding for Mplayer...
 

no problem.

Yes I missed that post in search, I usually do that. And I do not expect you to answer, I was just pointing it out... since this was latest beta. I knew that the codec and the bit rate encoding could be the key (as it was obvious from moving from Canola -> Mplayer)

I think maybe there needs to be an FAQ or Wiki for Canola would help a lot on these type of questions, I am not saying that you should do it, but a collective effort could make the questions be lower. It's just a cut & paste for different issues, and people could just look @ the FAQ.

Your project is definitely a hit and has lot of attention, so it's common for people to ask questions (doesn't matter if it's beta or alpha), so even though a search can find the answer (my mistake), you can't expect everyone to do a search. We're human after all... and I know you're all busy people.

Is there a wiki site you'd recommend for people to make additions or create an FAQ on common questions ? I'd be glad to help.

Re: Moving Encoding for Mplayer...
 

I think Canola is using xv output for playing, to embed it better. Omapfb output is faster, but not very embeddable - leaves screen artifacts on resize and has problems with fitting every rectangle size.

Hii Houman :

That's why I wrote :) because I don't expect, but it's common to try to "show" the possibility to one person here, other there :) then what happens : you (are not the case because you do search) but others will be reading others doubt and helping each other :)

I think I'm really experienced now with this issue and actually this is common place, people don't read the manual, and I will tell you :

If we (improve) the FAQ / Issues

http://openbossa.indt.org.br/canola/using.html#videos

The same thing is going to happen :) people dont read the manuals :) So I will be here pointing them out to the site ... but no problem, that's why I am here, because I want to help and listen.

In the end :) we are all very human !

@bundyo exactly :)

cheers !

Re: Moving Encoding for Mplayer...
 

Hello all

I've been trying to convert videos from RMVB to MP4, without success. I tried, I think, with all the apps that already have been cited in the forum:

- Internet Tablet Video Convert
- Media Converter
- Jaffa's Tablet Encode
- N800VC

None of them worked. I really don't know why, because I have the codec installed on my cpu, can watch them. I always receive the error that this codec is not supported.

Is there a way to make sure someone can convert RMVB?

Thanks very much

Re: Moving Encoding for Mplayer...
 

Marcelo,

I understand, totally what you say, but I would gladly help compile a list of issues / response and post them to a wiki or make a FAQ if you want me to. I did actually look @ your website and the known facts.

I also understand how people skip manuals... (hence the keyword RTFM) :).

Anyways, keep up the great work, you definitely bring lot of good to the Nxx0 platform.

Re: Moving Encoding for Mplayer...
 

Hey, Have you looked @ videohelp.com , I have used that site extensively for my conversion needs.

Hope you find a converter,
Houman

Re: Moving Encoding for Mplayer...
 

I tried many tools for converting rmvb/rm to mpeg4(Divx or xvid),this one is the best!
the speed is very fast,It take me about 10 ~20mins to covert a movie (rmvb to Divx).
WisMencoder 2.1.1.0
This is a free software and you can download it from http://www.mzys.cn/
or http://dl.pconline.com.cn/html_2/1/1...41%26pn=0.html
but it's Chinese vertion, I am searching English Vertion.
From the website I know there will be multi-language vertion after a while.
