Fastest H.264 encoder?
Can anyone tell me what program will be the fastest for encoding H.264/AVC for PSP, given that the machine I'll be doing it on is a P4 2.4Ghz with Hyperthreading, 512Mb RAM and an nVidia graphics card? I did a bit of searching around the net but it doesn't seem like anybody's really done any benchmark tests comparing different encoders.

Are you doing more than lets say 20 encodes for the PSP?
Encoding isnt only about speed (Actually it isnt). Encoding is actually all about perserving the quality. So what if it takes 40 mins to encode? BTW is PSP made for h.264 decoding? Since I doubt it has a processor good enough to decode h.264. Try a normal codec like mpeg2. |

For a comparison of PSNR/SSIM and speed of different encoders, take a look at this Doom9 thread. (Also, the ATI Avivo encoder is probably the fastest H.264 encoder now, but the quality is "lower than xvid" to quote the Doom9 thread, so you most probably don't want to use it.)

As far as Avivo is concerned, I don't have an X1000 series card; I tried the allegedly-hacked-to-run-on-all-cards version, but it just crashes when I try to run it. Someone suggested that it might require .NET framework 1.1 instead of 2.0, so I'm going to try that, but other than that, Avivo is not usable for me. |

IIRC the ATI avivox converter no need the .net framework(its only needed if you want to install the catalyst control center + avivox converter) to run, and now can download from ATI website, which is no hack or whatever.
all you need is graphedit, and some file writer. (imho this graphedit thing is same not use-friendly as cli apps) as for x264 cli encoder, its able to produce standard compliant h.264 bitstream, but not the container. if i remember corretly, you need an "atomchanger" apps to modifiy the mp4 header to make it as psp-comaptible file format. |
