there is a build somewhere in this thread that handle this pmpmod needs to be compiled setting high quality audio decoding / iirc the parameters in commented in one of the config files (also there is the need to push the cpu freq more to handle this) EDIT: config.h: #define CONFIG_MPEGAUDIO_HP 1 cpu...

I've got an idea, it is the way the PMP format can be managed... Actually you used a new container (a different one from mp4) for the video/audio parts... I've got this maybe very stupid idea : an external pmp patern file (50-60k) made by the parsing of the video and audio file on the PC that got t...

there is a little lib in pmpmod source that can be used to take advantage of the ME.
you can basically run a function in the ME, wait for it to finish, check if its still running.
the "only" thing to take care is a correct cache handling to make everything works correctly.

be aware that using more threads break compatibility with the internal psp decoder (the stream generated can't be decoded because frames are internally divided in slices)

left/right buttons are hooked up to rewind/advance 1 frame normally and 20 frames while X is held. not frames, but keyframes. advance it's not hard to do (you need to remove the keyframe check) for rewind you need to get the first keyframe before the point and decode all the frames until you get th...

you need a special version of mencoder to produce a compatible streams
a good practice is to search before asking

no one here is going to use illegal obtained pieces of the official sdk.

you also ignore my last answer about high resolution, in this way you easly run in getting no more answers.

yep i know when you enable more than 1 thread, the generated stream is no more compatible for example, with 2 threads, the frame is divided in 2 parts and the data is stored in 2 different NALs, the psp decoder seems to don't like this i think you can still use multithreading if you do multiple pass...
