Add http://feeds.cbsnews.com/podcast_eveningnews_video_1, CBS Evening news with Katie Couric, to videocenter and watch it under 2007Os and 2008Os. I am able to watch a 30min news streaming under 2007Os, be it 770 or N800 (N810 did not try), smooth and enjoyable all the way to the end. On 2008Os N8x0, it runs fine for five minutes, it then slowly deteriot and 10 min into its running, it is NOT watchable. Its video stutters horribly and comes to almost a halt. Audio deteriots later, but also comes to a complete halt in 12 min or so.

Kmplayer does not have this problem. It also streams video from various sources and is able to run forever without deteriotion.

RSS feeds using those URLs, CBS news with Katie Couric, same results. This suggests that the problem lies with media player instead of video ceneter.


Any comments? Suggestions?

Videocenter is my number one app. I am thinking to stay with 2007Os if this is the current situation.

Hmm, have you tried setting it to use kmplayer or mplayer instead of the built in media player?

I've never used OS2007 so I don't know if the video playback is better in it.

In general, media player renders better than mplayer. No, I have not tried that. Good suggestion, I am watching it under mplayer and see how it goes.

All are MMC booted.....................umm, you going to ask me how about internal flash boot? have not tried yet, will post later...

Might be worth trying. Having system on mmc can sometimes cause audoi stuttering. At least with stock media player or internet radio applet, not sure about mplayer. The problem is that since 2.6.18 kernel, mmcqd kernel thread has higher priority than audio daemon so with random mmc writing audio may stutter. If you hear this try to run
Code:
renice 0 `pidof mmcqd`as root to check if it goes away. Good place to run it is somewhere inside /usr/sbin/osso-mmc-mount.sh script which is run after mmc card is inserted. I have mentioned this few times but nobody ever complains about it so maybe it happens just to me :-)

As for 770 being better in smooth playback, maybe kernel preemption, http://www.linuxjournal.com/article/5600, helps too. N8x0 kernel is not preemptible so latency in kernel may be higher.

It is a little bit over my head. I tried the code pidof and returns,

error "wrong value for pidof"

I am still watching the CBS under mplayer and see how it goes...

bun

I just tried that : renice 0 `pidof mmcqd`

and it ran fine on my n800.

bunanson, the tearsync kernel plays videos very good in 770.

?

I guess the tearsync kernel is probably the kernal on 770. So....how do we go from here to help the 2008Os on the N8x0?


bun

No, tearsync isnt in 770 kernel by default. fanoush backported it in his custom kernel. N800 has tearsync in the kernel by default.

kmplayer is a frontend for the media player and mplayer, and I am trying to configure VC to use kmplayer as the ext player and see how it work; maybe kmplayer is more optimize to media player then media player itself (?).

The 2nd idea works some. I configured the VC to use mplayer instead of media player. It plays ALL 30 min till the end of the CBS news, streaming, without deteriotion over play time. However, my the mplayer has serious lag problem, even upon beginning. Video is prominently lag behing audio. You hear the word then you slowly see the mouth moves. It is annoying, I guess, it is still kind of watchable though.


kmplayer 0.8.2-1
mplayer 1.0rc1-maemo.26.n8x0
N800/mmc boot/2.2007.51-3

@qwerty12: You know how to make VC to use kmplayer?

I configured the VC to use kmplayer as the ext player. VC opens the kmplayer and that is all, it does not play the CBS news.

bun

No sorry, maybe kmplayer uses dbus to recieve a file. Hmm, I'll take a look later for a right dbus string (hopefully)
