It looks like they also updated their kernel patches, hope booboo is watching that

I may try to update mplayer anyway.

Well I know building from the straight svn source will yield and incredibly slow version, you pretty much have to include the ingenic asm patches. So if your going to try to move up to a recent version I would suggest trying to also incorporate the original asm code as well.

I know, I was just curious how big the difference would be and it is really incredible. Now that ingenic has released a new version of mplayer, I'll take a look at it. Maybe it can made run with the kernel I already compiled, hope it doesn't need the new kernel-features introduced. Else we have to wait for booboo

You may be able to look through the diff and do the patching yourself and rebuild if it isnt too complicated. I tried this morning but I cant download that patch at the office here so I dont know how big it is. The file size difference is not that much from the previous patch, so it could just be some minor changes.

At least the build-script was heavily modified. Anyway, compiling it was a blizz, so here's the new release:

For an update, you only have to replace the executables and the config-file.
It has improvements and regressions. Most videos I've tested ran very very well, but in some ff/rev will result in a loss of video-output. That may very well be a configuration issue, a little testing by the community may do wonders here.

OSD is still disabled because it is lagging.

Please, everyone, mess around with the config-file and tell me what you experience.
Have fun. Please, play around with the options

About the kernel issue...
It seems to me that i read on booboo's blog that it is possible with a proper tool (can't remember the name though), to switch the kernel while the system is running.

As far as I can remember, booboo said that dinamically allocate the ram needed by the IPU at kernel level implies some problems, so having two kernel images one with the ram allocated and one with not and switching between them when needed could be the way to go.

Anyway my hope is that someone can write a sort of "IPU enabled video driver" that could speed up performances on emus too (maybe this could mean rewrite jpeg/gif/and other libraries?).

I've contacted booboo yesterday about the issue, but I guess it will take some time till he can answer. There are some other things I need from him, so this isn't really an issue

I tested a flv :
video: flv1 320x240, 25fps, 330 Kbit/s.
audio: mp3 64Kbit/s 22KHz

Works quite OK. Regular lags, overall ok experience. Sound is great.
I'm going to try a H264 in a mp4 container.

Edit: the h264 try

Starting playback...

Slow but no additionnal lag. Sound is too slow to be pleasant. Going to try framedropping.

When I use -benchmarck on the flv it's the same speed as without.
But using -ac dummy -benchmark is very fast (over full speed).
Would it mean that the sound is eating a lot of cpu power ?

With -ac dummy -benchmark, the H264 is also speeding up but still not full speed.
I haven't tried overclocking yet.

By the way, thanks a lot, it sounds close to being functionnal. I love the progress that the Dingoo community is making every week !
