Tcmp-pxa Clocker Playback Issues

[sere83]

I have been messing around with My NX70V a lot lately and think i may be having tcmp playback problems. I installed my new battery which was fine. before I installed the battery I had opened the clie on 2 previous occasions and one ocassion the screen started flickering black and white and it went into a 'hard reset loop' and wouldn't start. I took the battery out again and eventually it started properly. Later on I had an issue with clie files and a normal 128 card not reading properly. Tried to read a file in Filez also and it crashed and I had to soft reset. Also The encoding program vemode also seems to produce corrupt files with bad indexes on my computer.

To cut a long story short I installed my new battery, reset the clie and now it is all fine. But........my tcmp (overclocked with pxa clocker to 266) is not playing back as smooth as it used too. I'm dropping approximatley 10 frames every 2000 is this normal? the files I encoded are Divx at 480x270 or 480X336 at between 430 and 480kbps and audio at 22050k 64kbps. Is this normal surely i should not be dropping any frames? Pxa clocker also benchmarks a lot higher some times at over 30fps but sometimes it goes bellow 20 and i have to press the on-off button on pxa and it goes back up to around 30fps. I am using pxa clocker 4.5 unregistered version. Is this an encoding problem or just they way tcmp plays back?

Also stuff encoded at a much lower res such as 336x252 still drop frames about 6 frames every 2000. Also does anyone know a good kbps to encode video at

can anyone help please?? I'm desperate

On my NX70V/G I encode for TCPMP at 384x288 15.0 fps @ 336bps MPEG4 DivX/XviD with MP3 @ 22050Hz Stero using "Super" to do the encoding.

PXA is set Mem 118, Bus 59, Sys 118, LCD 118 and Turbo Sys x2.5 to give a speed of 295MHz

When playing in full-screen rotated no frames are dropped, video quality is good upscaled to fit the screen when played from either the 4GB CF or 1GB MS Pro Duo. I use these settings so that 1 episode of "whatever" (40-45 minutes) is roughly 150MB in size. For me this is an adequate trade off for size verse performance, verse battery life.

Hello ! as you are using the free PXA clocker version you have to check it is really ON, before using TCPMP, because the free PXA doesn't always reactivate or get ON.

thanx guys. It is strange however as I'm sure i did not used to drop ANY frames in 100% full screen mode. My benchmarks are always above 30fps but i still drop frames. Even in video that is scaled down. I did briefly try and run tcmp at 294mhz, which caused it to freeze and I had to do a soft reset. Perhaps keeping the video data rate not much above 400 may help, when there is panning shots it just seems a little juddery. Does the amount of data on the internal memory affect playback? or should I just try and drop the frame rate from 23.98?

I figured out it only starts dropping more frames if you pause and then play again. I guess i'll just have to exit and and re press the ON button in PXA if I want to scroll through. Video playback does seem very power hungry though, my new battery seems to go down by 5-10% after only after a few mins of playback. This maybe cos its the first time i have used the battery and I havn't completely run it down yet. I only charged it for about 2 hrs when i fisrt got it, but the button on the cradle had gone off so I presumed it was charged fully, i'll put it on overnight once i've run it down completely. The battery meter seems to go back up a few percent after you exit tcmp though is this normal?
