What is a P64 file?
64-bit Windows plugin module used by IDA (The Interactive Disassembler), a utility used to disassemble executable files into low-level assembly language code; contains data written in C++ that extends the functionality of the IDA tool.
More Information
The P64 files are loadable libraries, similar to .DLL, that extends IDA's disassembling capabilities, such as the improvement of the analysis of Microsoft binaries with public debugging symbols. The P64 plugin should be placed in the /plugin/p64/ directory.
NOTE: Each IDA plugin uses a different extension depending on its operating system type. The .PLW extension is used for Windows 32-bit, the .PLX extension is used by Linux 32-bit, and the .PLX64 extension is used by Linux 64-bit plugins.

A P64 file may also be a video file encoded in the PVRG-P64 codec, which is based on the H.261 compression standard. It is used in the transmission of video and audio data for the purpose of portable wireless digital video communication. P64 files are rare since they were used in the 1990s and have been replaced by more efficient video formats and technologies.
More Information
The PVRG-P64 codec was developed by the Portable Video Research Group (PVRG) at Stanford University in 1993. The "P64" part of the codec name comes from "p x 64 Kbps," which is the supported rate at which the data can be transmitted (bitrate). The "p" value may be between 1 and 30.
The PVRG-P64 codec was supported by various video conferencing systems in the 1990s. Some systems include Parallax boards for SparcStations, IndigoVideo boards for SGI IRIS Indigo workstations, and Raster Rops boards for HP stations.
PVRG-P64 is based on the H.261 video compression standard, which is the first of several video coding standards in the H.26x collection. Other standards in this family include H.262, H.263, H.264, H.265, and H.266.
The H.261 standard was developed by the Consultative Committee for International Telephony and Telegraphy (CCITT), which became the Telecommunication Standardization Sector of the International Telecommunications Union (ITU-T) in 1993. The ITU-T specializes in the worldwide standards for telecommunication and initially released H.261 in 1988, then followed with several revisions to the standard in 1990 and 1993.
How to open a P64 file
P64 files are rare and few programs support them. Since the files are saved in a format based on H.261 compression, you may be able to open them with the cross-platform VLC media player or MPlayer programs.
You can also convert P64 files to a more common video file type with FFmpeg then play the converted file with a media player, such as Microsoft Windows Media Player or Apple QuickTime Player.
