Laggy video playback

[boostcraver]

Hi World,

Has anyone experienced laggy video playback for files stored on the SD card? Not streaming.. Is there any fix?

I'm new to the Maxx, just returned a T-mobile Galaxy S2 and ported to Verizon for the Razr Maxx. I'm liking the phone more so far, but one thing - the video playback is laggy compared to my old phone. The files on the same SD card I had in the old phone, which used to play back flawlessly, now play a few FPS less on the Maxx, making it look laggy. This is both divx and MP4, not crazy sized files, normal 700 meg files.

I tried adding mx player to see if this would fix it, but it hasn't. I'm wondering if there is a difference in resolution on the screens that could be causing this, since the cpu and ram specs seem to be about equal. If anyone has ideas on handbrake settings to change the res I will re-encode to see if it fixes it. I'm still running 2.3.6 unrooted too if you are wondering.

Thanks much,

Boostcraver

Try a different card.

Thanks for your suggestion, I've duly copied the video files to the different SD card but the lag remains. Any other ideas?

The original card is a kingston class 4 8 gigger, made in Japan. The second card is a generic 16 gig class 4 made in taiwan which came with the phone.

According to this link: Samsung Galaxy S2 Vs Motorola Droid RAZR Maxx: Fierce Android Battle Continues - International Business Times

Razr Maxx res is 960x540
Samsung Galaxy S2 Resolution: 800x480

VLC indicates my first divx has a native res of 612x340 with a bitrate peaking up to 1500 kbps.
The second divx (it wasn't a MP4 as I thought) has a native res of 640x272 with a bitrate peaking at 2500 kbps.

21 minutes to re-encode as MP4... you gotta love 8 cores. If that doesn't play back more smoothly, I'll re-encode to the native resolution and try again. Then I will start decreasing quality until it plays back properly, and post my results.

Unless someone has a magic bullet. I'd prefer not to have to re-encode my collection just to make it conformant to this phone, where the S2 can do it natively.

The resultant mp4 was 485 megs, where the original divx was 700 megs, and the mp4 encoded file plays back great!

I found the divx file looks a little better (stills are more clear and defined), while reviewing I also corrected the divx playback issue as well. When using mxplayer there is an option in the upper right hand side of the screen showing the Decoder which is set by default to HW. Hardware decoder perhaps is the GPU capability. I changed this to Software decoder (uses exclusively CPU to process the video) and the divx file playback for the original two videos works great!! Note - the MP4 playback is fine using the HW decoder.

I tried doing the same in the native Video Player app, but there is no option to change the decoder. In mx player you can adjust the default decoder in the settings.

Hope this helps someone.
