Hi,

I have a smartphone on which I transfer movies to watch. I am using an app called MX player. The app plays the video using either software based decoding or hardware based decoding.

When I encode a video using ffmpeg or handbrake and then play it back on the smartphone, MX player uses hardware decoding to play back the video which is good and playback is smooth.

When I encode a video using mencoder, the MX player app uses software decoding for the video and playback is jerky with audio delays.

What switches do I need to pass to mencoder so that MX player can use hardware decoding instead of software decoding?

thanks for any suggestions

I think it's going to depend on what goes into the container file...

Typically, I use AcidRip, a mencoder frontend, to rip movies. I rip them to avi files with lame encoded sound and mp2 video in the container. I've never had a playback problem with those files. However, MP4s from Handbrake,... not all players can handle them.

Look at what the hardware chipset supports to decide what container you use...

Hi JaseP

Thanks for the reply. Actually, my smartphone can handle mp4 files encoded with ffmpeg and handbrake. However videos encoded by mencoder does not play well on the player but plays fine on the desktop.

Anyway, this is not a priority. I was just curious of what switches to pass for mencoder so that videos can use hardware decoding when playing on portable devices.

As I was trying to say... You need to determine what the chipset can accelerate,... and transcode files to that format. Most transcoders have a default that corresponds with the container file and internal formats that were considered popular/superior at the tine they were developed.

What chipset does the mobile device have,... Davinci?!?!

Sorry for the delay in getting back.

I have a samsung admire. The processor is an ARMv6 800Mhz. The chipset is unknown. I did a google search but couldn't get that info. Graphics chip is unknown.

The file container I used is avi when using mencoder. Below is an example code I used

The avi files play smoothly on the desktop but not well on the smartphone but mp4 files play smoothly on both the desktop and smartphone.

I think by defaultk mencoder doesn't enable something to use hardware decoding when encoding/playing avi files or maybe my smartphone is under powered. Maybe I should get a dual or quad core smartphone

Anyway, thanks for the follow up...
