Problems with playing/recording 720p videos
I am creating this thread for those who have problems using Harmattan DSP codecs to play/record 720p. If all of you having problems continue to post on the original 720p thread, it will soon become useless. So post your problems,comments, jokes, curses, etc. here.
Thanks. |

Anyway, copy again bridgedriver.ko from 720p.zip in appropriate place. |
Re: Problems with playing/recording 720p videos
I need to know how can I overclock DSP. I did search but couldn't find it.
Is it mandatory to overclock DSP? 720p videos lags for me. Thank you. |
Re: Problems with playing/recording 720p videos
Mostly repeated from the old thread...
I've been ripping some DVDs with Handbrake for play on my N900, using these new DSP drivers. Even non-720p h264 m4v videos play much more smoothly. Unfortunately there does seem to be a correlation between the N900 clock speed, the kB/s rate of the video, and gstreamer's willingness to begin playing the video. freemangordon stated this is likely a mafw-related issue, since lowerlevel gst cli can launch just fine. For my part, I intend to investigate this by ripping the same sample at multiple bitrates and testing playback. |

Ok... to overclock DSP. this had been explained many places, one could easily refer the wiki.but anyway,:cool: browse to below path(or your custom file path, i have my custom file there) and edit the profile which you currently use on a daily basis . usr/share/kernel-power-settings you'll find some thing like below # minimum frequency to use MINFREQ=250 # maximum frequency to use MAXFREQ=600 # list of frequency configurations: each "frequency:volt,dsprate" FREQS="0:30,90 125:30,90 250:38,180 500:48,360 550:54,400 600:60,430 700:60,430 750:60,430 805:60,430 850:60,500 900:60,500 950:60,500 1000:60,500 1100:72,520 1150:72,520" edit the figures in red to whatever you like (max 600) and save it. run below as root kernel-config load xxxxx now when ever you reach a certain cpu frequency the relevant DSP overclock will also apply. to ensure smooth payback/recording, you can lock the cpu to a certain frequency which will lock the dsp too. eg While watching a 720p movie, kernel-config lock 700 After watching kernel-config unlock ps: i've used the default profile above for explanation purposes only, use your own voltages for your device. hope this helps nkirk |
Re: Problems with playing/recording 720p videos
With DSP@600 and CPU@1000 on max voltages I can record only 20 frames per sec on 1280x720 in cameraui. Is there anything I can do to get some frames more? Same result is when recording with gst command from cli.

Re: Problems with playing/recording 720p videos
hi guys, i have a kind of major problem :/
after installation of the 720rec app, my phone no longer shows any applications. i know they are still there, as i can access conversations, phone, contacts and xterm through the gui and keyboard shortcuts. i have tried a reboot, i have tried both the power kernel and original nokia kernel (i have multiboot installed) and nothing has helped. would anyone know how to uninstall 720rec using xterm? because i believe that it is causing the problem. if you do know how, that would help a lot :) EDIT: fixed the problem went into xterm and typed: root apt-get remove 720prec apt-get purge 720prec and did a reboot. hopefully it helps other people who had the same problem. :) |
Re: Problems with playing/recording 720p videos
Why do you post here?
In the HD-Recorder thread, there is a new version, where this problem is fixed for good. http://talk.maemo.org/showpost.php?p...4&postcount=43 |
Re: Problems with playing/recording 720p videos
Thank you nkirk for the DSP guide.
I still have problems playing the 720p videos. It lags and plays frozen frame by frame in KMPlayer. Not playing at all in Stock player. Please help. Thank you. |
