Re: 480*272 only version

Don't be so sure about that, I and many others I talked to hate to convert movies for one time view. The only thing I want this player is for just moving the movie to my memstick and watch it. No converting and hassle. And definetly NOT remove the resize code! And it is not the problem. Are there a...

480*272 only version

I have looked a bit on the source code, but I must confess. This is way above my programming skills. One thing I did see, there are pretty much code there to handle resize etc. Is it possible to create a stripped version that handle only 480*272 resolution. You could skip a resize and at least (mayb...

The best solution yet to play 480x272 videos.

Great work, soon we can watch movies in the only acceptable resolution. I've some troubles encoding videos that work thought. I Use 3GP_Converter 0.32 (FFMPEG) with various settings (all 480*272) but none works. It hangs after about 4 minutes while playing files, and for some it hangs while loading ...

0x7c1f = 111110000011111
0x03e0 = 000001111100000
I Thought 5551 was RRRRRGGGGGBBBBBA, so where did the A Go?

(a & maskRB) + (b & maskRB) is 16 precision ok for that, or are all operations in 32 bit and then masked for 16bit in the end?

The "mp4" player in the PSP only thinks it needs memory for 76800 (320*240) pixels so a movie in 480*272 resolution will overflow its memory. It will try to put data on memory areas used for other things and the PSP will hang.

Multichannel to Headphone surround support.

I would be really nice to be able to play movies with 5.1/5.0/4.0/3.0 sound in the headphones. For that we need AC3 decoder (or multi-channel AAC) and Dolby Headphone (or TruSurroundXT) coder in MediaCenter. I know 5.1 streams consumes a lot of bandwidth, but 3.0 would be nice to. Unfortunately I ha...

I dont think the 76800 pixel limitation is coded in to the player. But we have to remember we tricks it to believe it only need that amount. We have tried all the different resolution and none is much better than 320*240. The best with this discover is that it is now for sure that SONY have put in t...
