How to enable the Media Engine (video playback)

[hyakki]

the pmf file is a container format much like MKV or OGM it has atrac3+ audio and h264 video as seperate files, jpcsp cant decode the audio, sony owns the format and no free codec exists on the pc to decode to format.
the reason why jpcsp can decode the video is because its just standard h264 format that most players can play
.
the only way to decode audio would be to reverse engineer the format and no one has been up to the task yet.

so the alternative is to decode the files on the PSP there you can get a raw file like PCM and then jpcsp can understand the file.

Just thought this is something interesting about the long-standing discussion of decoding at3 (as an alternative to downloading SonicStage):

I believe this is the relevant file (as an alternative to downloading SonicStage - look for atxdec.ax and atxparser.ax):

Also, weren't ffmpeg able to get Atrac support and they're not Sony affiliated?

Forgive me if I'm just repeating known information as I'm a bit of a noob here and still in uni.

FFmpeg has atrac3 support but not atrac3+ (plus)

all you need from sonicstage is the OpenMG codec but i didnt want to confuse people since its more steps, its more easy to just install sonic stage rather then extract the contents out of the temp dir and manually install the openMG codec.

anyways might want to take a look at this thread
