[Psy-X] Playstation MDEC and ADPCM XAs support

[SoapyMan]

Right now STR and XA files are converted from Playstation formats to simpler formats using JPSXDec software.

STR FMVs are converted to AVI files with MJPG encoding.
XAs are converted to WAV files.

Game needs to have both original files and converted to be supported.

I'm trying to upscale the FMVs, do you know if there is a perceivable loss in quality from JPSXDec's conversion? Do you know if I can change the conversion settings in JPSXDec?

Also, the audio file in the converted FMVs is just 18.9 kHz in sampling rate, is this the original sample rate?

BTW, thanks for the amazing project, great work.

I've upscaled the first FMV as a test and here is the result:

I still have to add the audio back. Basically what I did was:

• Dump frames with FFMPEG
• Filter all frames with ESRGAN (JPEG 20-40 model)
• Assemble the frames back with FFMPEG
• Upscale with Topaz Video Enhance AI (Gaia-HQ v5, 1920x1080, no cropping, mp4)

It looks much cleaner (less artifacting, macroblocking) than just upscaling with Topaz and still has a decent amount of preserved detail.

@SoapyMan What audio/video codecs and container REDRIVER2 supports?

[SoapyMan]

@DonelBueno hey! Nice job, that looks good!
Right now codecs it does only support are mjpeg and wav in avi container because I'm still learning how to implement libavcodec/libavformat into it.

[DonelBueno]

Thanks =)

Oh, good luck on that, I would help if I had the knowledge.

Instead of embedding libav, it might be worth looking at pl_mpeg. Disregard, as I realise that the FMV are encoded using MDEC and not MPEG-1.

Şu anda STR ve XA dosyaları, JPSXDec yazılımı kullanılarak Playstation formatlarından daha basit formatlara dönüştürülmektedir.

STR FMV'ler, MJPG kodlaması ile AVI dosyalarına dönüştürülür. XA'lar WAV dosyalarına dönüştürülür.

Oyunun desteklenebilmesi için hem orijinal dosyalara sahip olması hem de dönüştürülmüş olması gerekir.
