* Real-time volume boosting(1-20x). Apart from system volume. (Can be used for Replay Gain. Of course by hand not automatically.)
* Super high quality custom YUV rendering using PSP video acclerator. Precise color conversion. Deblocking in chroma channels. (from PSPlayerMT)
* Fast avi loading by optimizing index loading.
* Max video resolution. 480x272. (PSP HW codec library does not support higher resolution. maybe)
* No restriction in framerate.
* Buffering mechanism used in PSPlayerMT. (but extreamly reduced buffer size.)
* FF/Rew supported.
* Using internal bookmark mechanism, resuming supported.
* Async reading of video files. Less memstick access.
* usbhostfs, nethostfs supported. (first should be enabled using irshell. etc.)

□ : Show player debug info
START : Pause/Play toggle
Analog Up/Down : Boost volume 1x-20x (in SW)

1.3 Additional notes on video player

* Most of software codecs are removed to reduce pbp filesize. (except AC3)
* Sometimes H264 decoder fails.
* After decoding of Mpeg4 video(xvid), H264 decoder crashes occasionally. (in sceMpeg library)
* Recommended encoding software. (regardless of codec)
- to avi files. Badak. always my favoriate. (http://www.kipple.pe.kr)
- to mp4 files. XviD4PSP 5.x. Good for mp4 files. (http://www.winnydows.com, avi not working)
- no special conversion setting is required for H264. (just select file, setup codec and convert.)
- HW xvid decoder does not support b-vop(b frame), gmc, qpel. When encoding with xvid, disable unsupported options. (With mencoder, add -xvidencopts max_bframes=0:nogmc:noqpel)
* Have an option for RGB rendering of Mpeg4 video.
* First audio track only. No multi-track audio.
* developed and tested on 3.90 M33-5(1.5 addon, fatmsmod patch) and tested on 3.71 M33-4(?, 1.5 addon) and OFW 1.5 on DAX's time machine. (not a slim psp)
* Full compatible list of container and codec combination. (tested.)
- AVI - opendivx/xvid/h264 - ac3/mp3
- MP4 - xvid/h264/opendivx(?) - mp3/aac
- any combination of video/audio codec is supported. (ex. avi h264/ac3 ok)
* avi files takes additional 10MHz CPU clock.
* ac3 is not recommended. for compatibility only. It takes additional 50MHz CPU clock.
