PMP Mod is a media player for PSP. The Mod suffix indicate that this is a modified version, based on the original version from JiniCho.

User guide

Video:

• MPEG-4 ASP is supported (for performance reasons, the use of QPEL and GMC is not recommended).
• Resolution up to 720x512 (width and height must be both divisible by 8).
• Frames per second between 1 and ~38 (no more than 25fps are recommended, this is for performance reasons and due to the way i handle vsync).

The video need to be placed in an avi container in order to be handled by the PMP Muxer. You can use VirtualDub and XviD to handle the video conversion.

Audio:

• CBR/VBR MP3, Stereo, 44100Hz.
• (supported bitrates are: 32, 40, 48, 56, 64, 80, 96, 112, 128, 160, 192, 224, 256, 320 kbps).

You can use BeSweet v1.5b31 and BeLight 0.21 (or a more recent version) to handle the audio conversion.

Changelog

PMP Mod v2.02 2006/07/18

• Speed increase (640x272 MPEG4-SP goes at ~28fps).
• Fixed some audio problems (random pops, mainly audible with headphones).
• Added loop option (x + right trigger to toggle).
• New key mapping.

PMP Mod v2.01 + PMP Muxer v2.01 2006/05/28

• The color space conversion is now done with the GU (inspiration taken from the standard JiniCho's PMP 0.0.6). Speed increase of about 4fps. *Quality also slightly increase (due to chroma interpolation).
• Luminosity boost - with right/left trigger (inspiration taken from malloc).
• Aspect ratio - you can switch between original, 4/3, 16/9, 2.35 (right/left with the analog joystick).
• Zoom up to 200% (up/down with the analog joystick).
• OSD (O to activate it)
• Player & Muxer: the new video resolution limit is 720x512 (obviously 720x512 clips will stutters a lot)
• Muxer: added the check for writing errors.
• Notes for developers: The only ME code left is for the idct. I've also changed the memory allocation strategy (now there are no assumptions about the initial free memory). This means that should be easyer now to make it work on fw 2.00+ (to make it effectively usable, some optimizations are still needed).

PMP Demuxer v1.00 2006/04/24

• The demuxer is a command line application, the easyest way to use it is to drag and drop files over it (the files will be written in the same dir of the pmp, along with the log file containing the result of the operation).
• The avi file created is slightly out of specs, when bigger than 1GB. Anyway there should be no real problems up to 2GB.

Credits

Many thanks goes to JiniCho for porting FFMPEG and FFPLAY to PSP. Without his work, this modified version would never be possible.
