Point of the situation.

1-installed a new image OPENATV 6.1
2-installed Oscam EMU oscam-1.20_svn-r11438 with reader
3-I uploaded via FTP from the Astra folder (Albertis)
4-I executed the command (ssh) opkg install astra-sm
5-reconfigured the astra.conf file in the box
6-I added with Dreamboxedit the bouquet albertis

canals albertis... just a black screen.

What am I doing wrong?

And edit lame.db and upload it to the box in stopped enigma, not through DreamboxEdit.

I'm using the keys that are in the manual... are those?

Do you know any solution for the sound in Vu + zero 4k after upgrading to the openATV 6.2 version?
Thank you

I'm having big trouble getting it to run on a DM820HD (Mipsel) with OpenATV 6.1... Picture drops after 5-10 seconds, only the autonomicas with low bitrate run without interruption.

Seems as if the abertis script for astra-sm either crashes or cannot cope with the higher data rate of the HD and other SD channels (log says 'dropped x packets while waiting for child'). Reception is fine, >13dB.

may be its a RAM issues in your box

check debug from astra-sm

A typical log would look like this (works for 5 or so seconds then stops):

After a while it works again for up to 10 seconds, log:

Code:

Nov  5 23:12:34 dm820 user.err astra[631]: [pipe_xfrm Abertis PID 703 #1] dropped 983 packets while waiting for child

Nov  5 23:12:44 dm820 user.err astra[631]: [pipe_xfrm Abertis PID 703 #1] dropped 67584 packets while waiting for child

Segfault and code 139... on the autonomicas it works flawlessly.

The process
/etc/astra/scripts/abertis 703
gets a new PID every couple of seconds, so obviously it crashes and gets restarted all the time.

The box has
- 7.000 MIPS Dual Core Processor
- 4 GB Flash
- 2 GB RAM
Specs sound ok?

Memory use doesn't seem to be the problem as far as I can tell:

Code:

Is the code of the abertis executable available anywhere?

bad streamer in your image

Thanks for your answers, I'll try and investigate further.

Brilliant!

That fixed the pixellation/freezing on my ARM based Ultimo4K.

I edited the file /etc/sysctl.conf to add these lines

Code:

## added for Abertis ###
net.core.rmem_default = 16777216
net.core.rmem_max = 16777216
net.core.wmem_default = 16777216
net.core.wmem_max = 16777216
net.ipv4.udp_mem = 8388608 12582912 16777216
net.ipv4.tcp_rmem = 4096 87380 8388608
net.ipv4.tcp_wmem = 4096 65536 8388608
net.ipv4.tcp_tw_recycle = 0

Then in telnet, to apply the changes I ran

Code:

sysctl -p

After a short period of stabalization the picture is now perfect.

Same here! It works after applying these changes on my DM820 with OpenATV6.1! Thank you so much @xosef1234 (and @007.4)!
