Greetings rockbox community,

I must apologize in advance for my bad english. :C

Recently I have installed on my ipod video 5th generation rockbox 3.8.
Now I wanted to test the video plugin.First I had to convert my video files from avi to mpeg.I decided to use WinFF as program.Some of the data for the settings I've taken from here --> http://www.rockbox.org/wiki/PluginMpegplayer.
For example: Frame Rate 14fps or the Video Size 320x240 for 4:3 Full Screen.
Which I still missing is the Video and Audio Bitrate, Aspect Ratio, Sample Rate..

Although the video file is played, but sometimes it`s very jerky.
Maybe someone can help me with the data..?

Thanks in advance!

Kind regards,
moki

Unfortunately, it seems you've done everything correctly. I say "unfortunately", because probably there's not much you can do to make the video less jerky.

The iPod Video has a bad video playback performance when compared to other color LCD iPods Rockbox supports, despite its model name, "video". This is because no one knows how to use the video decoder chip that Apple Firmware uses, thus all the decoding has to be made through the main CPU, and as the iPod Video's screen is bigger, this demands more CPU, and as the CPU is not to the task, it ends up with jerky video.

In conclusion, you'd be much better watching videos through the original Apple's firmware (you can boot into it by turning Hold on just after the iPod is turned on). If you don't like using iTunes (just like me) this will be a major drawback, but the video won't be jerky :)

moki:
Hey gbl08ma,

thank you for your response.

Hm, that sounds even less good.What about the missing configuration settings?Video and Audio Bitrate, Aspect Ratio, Sample Rate..?That would be a beginning, I think.
Do you have an idea in this regard?

What the itunes use concerns:

If I want to watch a video with itunes, I save the file as usual with itunes(or in my case with winamp - because Apple ist the enemy) and afterwards boot itunes to watch the file, right?

Greetings,

Chronon:
The preset in WinFF should be correct for your device.  You might make sure that you have "skip frames" enabled.

Hey moki,

I personally don't use rockbox but the OF to watch videos on my ipod due to the discussed shortcomings.

But if you want an easy and a non-apple program for transferring videos to your ipod I can recommend "copy trans manager". Before that use WinFF with the preset ipod-itunes to convert the video and you're fine.

@Chronon: Maybe I overlooked it, but I couldn't find the "skip frames" setting in WinFF. Could you explain that a little? Would be nice.

Greetings,
