Just got rumours from the Playstation Meeting 2005 that Sony are introducing new 2.0 firmware for the PSP that enables H.264 AVC playback from memory stick, no more 3GP craptastic encodes, silky smooth top quality videos, i cant wait.
Unsure if its enabled full res 480x272 playback.
Interesting, but not really my cup of tea. Try re-encoding a DVD to that resolution without artefacts.

I don't see the problem, really...
480x272 is a 16:9 resolution, and compressing with AVC would not create many artefacts if you set a resonable bitrate. If you have a 512 MB MemoryStick you can go up to 600 kbps (Video+Audio) for a 2 hours movie. More than sufficient.
seeing is believing

PSP's are small, the low resolution shouldn't be a problem.

well its known for a long time already that the psp can decode avc from umd discs, so its no news at all that avc handling exists
whats the special thing discussed in this thread imho is that there might be the possibility to play avc from memory stick, which is a huge difference, as than you could produce your own high quality movies yourself (if sony supports the .mp4 container too with avc, which isnt sure at all. and if i look at that for aac playback the psp needs proprieatary extensions to .mp4 for the playback...)
not a screenshot.. the actual firmware available on an actual PSP you can buy in a store
And then of course there's still the issue of having to buy Sony's proprietary stick where the rest of the world uses SD/MMC or CF.
Team xecuter announced a kit () called PSPX mass storage that plugs itself into the memory stick socket of the PSP and then allows you to connect SD/CF/USB storage that would be recognised by the PSP... .the usb drive thing might change the PSP into a PSNotSoP but if it can be done then... if it works then that's very good thing!
With the coming 2.0 firmware, Sony will now allow the playback of AVC files in Sony's quot;Memory Stick Video Formatquot; (MSVF). This is the same format that Sony uses for its MPEG-2 SP videos that are playable on the current versions (1.00/1.50/1.51/1.52) of the PSP Firmware.
What this means is that the AVC video will likely be stored in Sony's non-compliant MP4 container and _probably_ support AAC for audio. Also it seems that AVC videos must also follow a similar stupid naming convention for them to show up in the PSP menu(10xANV01 subdirectory, MAQxxxxx.MP4).
If all that is not bad enough, according to someone who has seen the MSVF specs, the MSVF-AVC video is only supposed to support a max resolution of 320x240. Whether or not larger resolutions will be possible with header hacks has yet to be seen. So native resolutions still may not be possible
Finally, we should note that this is NOT the format used for UMD videos and cut scenes in PSP games. That format is known as the PSP Movie Format (PSMF) which uses AVC for video and ATRAC3 for audio in a MPEG-2 PS container.
so it sounds just as #¬¬°§@# as it is now with ASP. Until somebody writes a third party player that works with standard MP4 files I find that quot;video supportquot; an insult.
The UMD uses AVC muxed into mpeg-2 ps container with some unkown headers simliar to 'PMF' which is used for for video clips found in UMD games, The file type is .mps which is not known and has a resolution of 720x480 which then gets downmixed to pspscreen rez,
I recall the audio type found in .mps being atrac3 I think...

thats the .pmf format (not sure if it will be used in umd)
sony loves to bastardize standard formats...

lt;pasted from another threadgt;
the HUGE downside is 1.51, 1.52, 2.0 will be patched against running homebrew (as well as piracy). homebrew, specifically, that plays MODs (/XMs/S3Ms/ITs/etc), OGG Vorbis, PSFs, etc among many, many other programs (NES, SNES, MAME emulators, TXT viewers, and possibly Demoscene demos)

Lo and behold!
the PSP has such a great potential when you can mod it to do what you want..
It's annoying that Sony is trying to make it difficult for the end user to use their product the way they see fit (ie the latest games won't work unless you have the latest firmware update, which is difficult to do if the device is modded for homebrew).
Playing video from a memory stick is alright..
however, being able to play live video streams (wired or wireless) would be AWESOME. I can think of alot of reasons why a PSP wireless video terminal would be worth while.

Precisely my problem with Sony, all their proprietary bastardized standerds!! They have decent hardware usually, but its so crippled by being limited to their in house development. If only they had a clue about all the cool things that open source can provide.
I suppose they're a corporation that's out to make money, as all ultimately are. Unavoidable.

Avc on UMD Games is in 'PMF' and AVC on UMD is 'MPS' where the UMD AVC is much better quality such as bigger rez/bitrate and SP on ms is 'MP4'
I'm not that excited about h264 support on the PSP, because Sony already stated it'll only be 320x240.
They are just putting limitation everywhere to sell a lot of their UMD video crap... (I don't even understand how people can buy such a crappy product @ the same price of a DVD, and don't say to me it's portable balbla cause portable dvd player are ultra cheap these days...)
Hopefully someone will come up with a hacked firmware. If you could play 480xXXX encodes on a PSP, I would definately buy it! If Sony only realized the potential of the PSP! I can't see why they try to stop it, it would only make it popular with more people. But I guess they are paranoid about 13-yearolds cpying eachothers games or something.... |
