A performance issue on single-core processors fixed in build 3770 (Stanley posted on June 14th, 2007 )
Today I found that recent builds have a critical performance slowdown on single-core processors. As I am using a Intel Core2 which is a dual-core processor, I failed to notice this issue until I was told that MediaCoder’s speed on single-core processors has recently become very slow under some combinations of settings.
After some investigations, I concluded that this issue occurs when following factors meet together:
- Target video format is XviD
- Target container is other than AVI (e.g. MP4)
- Audio is not disabled
- Audio encoder is an executable (instead of a DLL)
The root cause of the issue is the the priority of audio encoder process is not set properly, which causes the audio transcoding thread to fall behind the video thread seriously and brings performance penalty.
On dual-core processor, this won’t be an issue because a low-priority process (in this case, the audio encoder process, e.g. lame.exe) won’t be blocked by another busy process (in this case, the process of MediaCoder).
Luckily it is found out and fixed. Please update to build 3770.

Tips for encoding AMR in MediaCoder (Stanley posted on June 9th, 2007 )
For a successful AMR encoding in MediaCoder, you have these steps to follow:
- Update MediaCoder to 0.6.0.3760 or later
- Download and install AMR Codec Pack for MediaCoder
- Start MediaCoder, switch to Audio tab and set Audio Encoder to AMR
- You can choose between AMR-NB or AMR-WB in the AMR tab on the right side
- Do click on either AMR-NB or AMR-WB radio box as this clicking will make the correct resample and channel options (8Khz/mono for AMR-NB and 16Khz/mono for AMR-WB)
XviD encoding speed vastly increased on dual-core systems (Stanley posted on June 6th, 2007 )
XviD encoding core is updated with the multi-threading enabled version in MediaCoder 0.6.0.3750. This brings increase in XviD encoding speed by 30-40% on dual-core systems.

Nominate MediaCoder for SourceForge community choice awards 2007 (Stanley posted on June 6th, 2007 )
SourceForge.net is presenting the second annual Community Choice Awards. Winners are selected by community members, just like you. If you like MediaCoder, please do cast a ballot for MediaCoder to nominate it. Winning this awards will be a great honor for me in my lifetime and bring me big motivation to improve MediaCoder towards perfection.
Here are the steps to do the nomination:
- If you already have an account on SourceForge.net, you can skip this step, otherwise you’ll need to create an account on SF.net first (I know this takes some time, but please do me a favor).
- After you got your account, login with it and go to the nomination page.
- Choose a category that you think is best fit for MediaCoder. If not sure, you may just choose Best Project for Multimedia. You can nominate MediaCoder in more than one category if you want to.
- That’s all. As the SF.net page says, the final voting will begin on July 9th. By then, I’ll still need your ballot!
The User Interface of the upcoming Firefox 3 (Stanley posted on June 4th, 2007 )
Firefox 3 is going to provide a wide range of improvements to performance, stability, and security, and it’s also going to present several new user facing features. Here is a quick recap of design work that’s been going on in the Mozilla community over the past few weeks for Firefox 3, along with information about how you can help contribute, by providing feedback on these designs, or creating your own UI mockups.
