This is one of the coolest work I’ve seen in a while…..

yeah, that’s right…..
KDE ROCKS… \o/

chromium browser for linux is a beta quality software now…

Posted in open source, Review, Screenshots, software, Technology by notoveryet on October 8, 2009

I just upgraded chromium browser on my machine to¬†Chromium 4.0.222.1 (Ubuntu build 28248)“…

and now it supports,

– google chrome themes

– flash without any command line arguments (–enable-plugins)

It’s now comparable to google chrome for windows… except google-talk of course…

so I’m expecting google to announce the chromium browser as a beta software [ forget alpha ūüėČ ] soon..

???

What are you waiting for….. ¬†fire up your package manager and try it out…

chromium-4.0.222.1

chromium-themes

chromium-youtube

 

UPDATE:

Just found out, it still does not show new java based yahoo mail interface… so it cannot be called beta software yet….

nevertheless, we have now almost¬†perfect¬†flash support and stunning speed…

I think google will declare chromium as beta only after the implementation of some of these known problems and “google voice & video chat” support… ūüôā

 

multiple target patterns. Stop.

If you are encountering this error while compiling your project using cygwin:

————————————————————————-

make -j3 all

src/SwcAbCd.d:1: *** multiple target patterns. Stop.

————————————————————————-

then check the version of make tool

make –version

(the command has two ‘-‘ not one as it appears here)

and if it’s 3.81, revert it back to 3.80,

I don’t know how and why, but this worked for me….. ūüėČ

[ just for the record, I got this problem while I was compiling a project in Eclipse using cygwin gcc toolchain… ]

best video (media) player for the mobiles – CorePlayer

Posted in Entertainment, nokia, open source, software, Technology by notoveryet on September 22, 2009

As I am going to buy Nokia 5530 (based on S60 v5)….

there is a problem, CorePlayer is not released for S60 v5 yet..

so, where would I play the mkv (H.264, vorbis) videos? (there is no alternative to this holy player)

for those who don’t know what CorePlayer is: CorePlayer is collection of best codecs available in the world and it plays almost all the formats you ask it,

it’s a little brother of VLC and MPlayer.

I am planning to compress my favourite movies to 200 MBs each in the above mentioned formats…. and keep in my upcoming phone…

so, I wish CorePlayer release their new version as soon as possible…. ūüėČ

next time when you compress/rip a video…

Posted in open source, software, Technology by notoveryet on September 22, 2009

take these into your consideration.. ūüôā

There are three main components in – what we call a “video file” (“.avi”, “.mp4”, “.3gp”, “mpeg”, “.mkv” etc)….

– VIDEO (of course)

– AUDIO

– CONTAINER FORMAT

____________________________________________________________________

MY RECOMMENDATIONS:

Container format (or the extension of the file): MKV

Video compression format: H.264/AVC (using x264 encoder)

Audio compression format: ogg vorbis

software which will provide you all these options: Hand brake

____________________________________________________________________

what is “container format”?

well, generally the extensions of videos files are the “container formats”…

e.g. .avi, .mpeg, .mov, .mkv, .mp4..

these format keep one or more video, audio or subtitle files based on their capabilities, so these are like archived files…

The container format software knows how to extract (read) the video-audio-subtitle from the file and how to play them in synchronization…

Note: so when you rename an .mpeg file to .avi, its container format does not change… it’s still an mpeg file….

____________________________________________________________________

why mkv?

for number of reasons-

– it’s an open standard,

– future proof,

– its design allows to keep all video-audio-subtitle formats available in this universe…

– it requires lesser space than the other formats….

– can keep unlimited number of media files in it….

for more information read on wiki.

(i don’t understand, why people still use .avi?)

____________________________________________________________________

why H.264 (x264) video?

since H.264/AVC is best video compession hands down….(it beats Divx, xvid, real media, wmv, VP6-7)…

there is no comparision, believe me…..

it gives best quality videos on very less file size….

and to compress the video in H.264, there is this cool and fast encoder – x264 and it’s open source too.. ūüôā

in case, you want to play the H.264 compressed video on your disk player… just check the specification of your player…¬†since H.264 is not supported by all the disk players yet… (in that case you need to compress your video using xvid encoder)..

on the other hand, if you are going to watch on computer.. it’s all good… ūüėÄ

____________________________________________________________________

why ogg vorbis audio?

– it’s open source,

– best quality sound…specially for 128 kbps or less…

– again, less size for the great quality audio….

____________________________________________________________________

So, next time when you compress a HD video or RIP a DVD using “Hand brake” or some other converter….

go for these options..

РContainer: MKV

– Video codec: H.264 (x264)

– Audio codec: ogg vorbis

want to convert/compress a video, try HandBrake….

Posted in free, open source, Review, software, Technology, video converter by notoveryet on August 12, 2009

Here is one beautiful software….¬†“HandBrake“…

it’s a “FREE and OPEN SOURCE” video conversion and compression software… and is available for following platforms:

windowsdownload link

ubuntu linux – download link for 32 bit, download link for 64 bit

mac os x – download link

source code – download link

now a days, whenever i look for any software…. ¬†my search string begins with “open source” instead of “freeware” or “shareware”… and i am gaining confidence…

i found this software quite handy and useful..

just now converted a 730 MB movie file into a 198 MB (i asked it to make 200 MB) mp4 (H264 based)….

it took around 20 minutes for 2 pass conversion, which is fine for me…. and the video quality better than what I was expecting.. ūüôā
