Converting video from ameg to avi with ffmpeg

I have been using my Sony SCR SX 20 for quite a some time now. One of the the problem I see is that even though it does not record in High Definition (HD) , it consumes a lot of space.In fact for 22 Minutes of High Quality video it creates a .MPEG file with size 1.5 Gb. This is too large for uploading in any video sites like YouTube. I tried Linux GUI Tools like WinFF and Avidemux  but they elongated the video vertically and also sometimes conversion failed because of some library missing issue.

I found it can be done with ffmpeg and desired optimal quality can be achieved gaining some free space.

For best quality
ffmpeg -i 1.MPG -sameq 1.avi

For desired quality
ffmpeg -i infile.MPG -qmax 4 outfile.avi

Here the number 4 indicates that I need a moderate quality , higher the number lower is the quality and smaller is the output file size. You can hit and trial with a small file and choose your desired number. Same is applicable while converting MOV file to avi.

For Batch processing one can try
??for f in *.MPG; do ffmpeg -i "$f" -qmax 4 "${f%.MPG}.avi"; done

    Some other video conversions in FFmpeg are
    .avi to divx format: ffmpeg -i input.avi -s 320x240 -vcodec msmpeg4v2 output.avi
    .avi to dv format: ffmpeg -i input.avi -s pal -r pal -aspect 4:3 -ar 48000 -ac 2 final.dv
    .mpg to .avi format: ffmpeg -i input.mpg ouput.avi
    wav file to mp3 format: ffmpeg -i input.avi -vn -ar 44100 -ac 2 -ab 192 -f mp3 output.mp3
    ogg theora to mpeg format: ffmpeg -i input.ogm -s 720x576 -vcodec mpeg2video -acodec mp3 ouput .mpg

Load Testing Using Gatling

Gatling is an open source load testing framework based on Scala programming language. One of the advantage of Gatling over other load testing framework that I have used is that the code is very elegant and readable, thanks to its own DSL. One may not have prior knowledge of Scala to get started with Gatling. There are some documentation in the Gatling website which will help you write simple HTTP calls to your webservices but it gets bit difficult to incorporate the exact scenario of your test case because there are not much variety of example code which you can quickly edit and use. In this article I will try to show most of the structural construct that are frequently used while making a series of dependent web-service calls, typically used by a mobile game client while interacting with the game server.

Setup instructions are well described in the getting started tutorial. Following scala code will make a POST request to a mock REST endpoint that I have created using mockable.io.

Sharing Photosphere

I have been always a fan of panorama images. There are a lot of photo stitching software which can join many overlapping images to create a single one. I have used Photosynth earlier with a lot of satisfaction. There a lot of phones and digital cameras which can do it right out of the camera in panoramic mode, in which you have to slowly move the capturing device and it will continuously take and stitch photos to create larger panorama.  While there ares some websites like CleVR and GigaPan can help sharing the horizontal panoramas and let embed in various sites, spherical panoramas like the ones taken from photosphere app in Android 4.2 cameras could not be embedded in a straight forward way without doing some HTML coding. Finally I found a site called SphereShare.net for this purpose. Following is the embedded photo I took uploaded in this site.

Bengali English word definition in Google Dictionary

Image
It was good to see that Google Dictionary supports Bengali Language along with Hindi , Gujarati, , Marathi and Other south Indian Languages (Malayalam , Kanada , Telegu , Tamil)
http://www.google.com/dictionary?aq=f&langpair=bn|en&q=অভিঘাত+&hl=en




























Similarly most of the Bengali words’ english meaning can be determined as follows
http://www.google.com/dictionary?aq=f&langpair=en|bn&q=irony&hl=en




























However the Bengali font size was so small that I had to Ctrl + “+” to make them properly visible.
I hope Only major remaining  language Oriya will follow up.
This feature might be available shortly as part of other features of Google Search bar.
