How to play m2ts files smoothly using VLC

Posted 02 Mar 2010 — by Arun
Category Technology, Ubuntu

I recently bought a Panasonic HD camcorder which records the videos in m2ts format. m2ts is a high definition MPEG format used in Blu-ray discs and AVCHD. After I copied the files to my desktop, when I tried to play the video using VLC, it was jerky. It wasn’t smooth at all. When I played the video using the Panasonic supplied HDWRITER software, it was smooth. After Googling, I got VLC to play the video smooth. All you have to do is, go to Tools – Preferences in VLC, select Input & Codecs option and select ALL from the drop down menu for Skip the loop filter for H.264 decoding (picture below). Save the preference and play the video. The video should be smooth and perfect. I tried this in Ubuntu 9.10, but it should work with all OSes.

Google code hosting site distributes malware

Posted 12 Jan 2009 — by Arun

Spammers are using Google Code, a website where developers can host projects and codes, to distribute malwares. According to McAfee, they are creating lots of new projects with titles such as Live Free Sex Movies and clicking the image will take you to today’s fake codec download site. Repeated clicks will take you to an adult site. The codecs turn out instead to be password-stealing Trojan horses and programs geared toward stealing financial information for identity fraud.

A Google spokesman said the company has removed malware-distributing projects from Google Code and search results.

Ubuntu, Kubuntu 8.10 beta pain

Posted 23 Oct 2008 — by Arun
Category Ubuntu

I upgraded Ubuntu/Kubuntu 8.04 to Ubuntu 8.10 in my laptop when Ubuntu 8.10 alpha 5 was released. Everything worked fine except for couple of issues mentioned in the post. Network manager worked fine. There were lots of updates that came in from the time I installed alpha 5 including the updates that came with the beta version. After those updates, my ethernet connection was not working and same with my wireless connection. I tried different things and it still didn’t work. I then downloaded Kubuntu 8.10 beta yesterday and did a fresh install, after formatting the partitions. I then restarted my router. After I restarted the router and fresh install of beta, the wireless connection with WEP encryption worked, WPA didn’t. Kubuntu was still not showing my ethernet port. I then updated Kubuntu with the latest updates through the wireless connection and rebooted the system. Once rebooted, Kubuntu recognized my ethernet port and showed it as an option in the network manager. Wireless connection was also much better and faster after the updates.

There are still few issues I encoutered as of yesterday.

1. WPA encrption didn’t work eventhough wpa supplicant was installed. I couldn’t connect to my router if I set the encryption to WPA personal.

2. I installed the necessary codecs, but still neither the default Dragon player nor Kaffeeine played the mpeg file. I tried VLC and it crashed. The audio part was working fine, but the video part was blank.

3. The built in logitech webcam is still not working. Skype, AMSN etc showed it as USB webcam, but no videos. Ubuntu 8.04 recognizes it as Logitech quickcam and the video worked fine. The webcam video doesn’t work with Ubuntu and Kubuntu 8.10. I hope they fix it before the final release.

4. Kubuntu 8.10 showed the hardware driver window with ATI’s proprietary FGLRX driver. It said the driver was not being used. When I clicked the button to use it, nothing happened. I tried it couple of times and it didn’t work. I rebooted the system and tried it again, but it still didn’t work.

5. There were couple of times when KDE hung and I had to force shutdown.

6. Sound by default was low. I had to click the Mixer option in the Volume icon and increase PCIM and other options to get the maximum sound. It would be nice if those were defaults.

7. I included medibuntu repositories to install 3rd party softwares. I couldn’t install Google Earth 4.2 or 4.3 with medibuntu’s intrepid repository. I was getting errors during installation. Medibuntu’s hardy repository worked earlier.

I hope they fix 1,3 & 4 before the release candidate.

Update: #4 worked. I have found another issue. If I insert an audio CD, Kubuntu does nothing. Nothing pops up to play. Even the players don’t recognize the CD except VLC.
