Other news: while trying to process one of those badly encoded videos, I found that the I-frames are correctly encoded. For example, if I set intra_period=30, the first frame is ok, then the net 29 frames are not valid, and the 31st frame is again ok.

Anyone has suggestions?

I clarified thgat the problemi is not omxplayer. It seems that recording in python with picamera package corrupts the data. The same camera on the same system produces good videos through raspivid.
Is there any known bug and solution?

Thanks

Hi, I just started with a fresh install of raspbian jessie on a Raspi2, and a strange issue happens with omxplayer. While it is able to play correctly random videos of different sources, I can't make it play correcly raw h264 videos from the camera module. No error message dumped to the terminal, I ...

Hi, I'm successfully using OpenCV from python to capture the frames of a video, previously recorded to disk with the pi camera board. In a previous installation acquiring roughly 170 frames and doing some quick processing took approx. 15s. Now I started from a clean raspbian installation, installed ...

Hi everyone! I'm trying to produce a video file from a series of matplotlib plots. I successfully produced the video with the animation module of matplotlib, but it was far too slow for my application (it was saving temporary png files to make the animation) so I ended up feeding the raw images to f...

Hi, I'm trying to use python to capture video from the raspi camera to be processed later by scikit-image, therefore I would like to save images as numpy arrays. It is important to achieve the highest possible framerate (1296x730, 49 fps it's the best tradeoff from my attempts) and to save the times...

It actually worked! Thank you, now NFS is up running again

Thanks

Yeah, I know, I should be more careful and always remember to sync before rebooting... Today I tried to pacman -Syu, there is a new kernel update which I was hoping could solve the problem... This is what I get after checking for conflicts: error: failed to commit transaction (conflicting files) lin...

Hi sorry forma my late reply...

The procedure described in the other thread doesn't seem to apply to my system... Can't find those files...

The system has beer rebooted several times after update, probably the first without syncing. And it has been powered off several times as well.

Thank you

Hi, I think a problem similar to this: http://archlinuxarm.org/forum/viewtopic.php?f=33&t=6049 is now occurring on my raspi... [root@piserver ~]# uname -a Linux piserver 3.10.32-1-ARCH #1 PREEMPT Mon Feb 24 02:03:19 MST 2014 armv6l GNU/Linux [root@piserver ~]# pacman -Q linux-raspberrypi linux-raspb...

Thanks for the advice, the USB drive is a 3.5" thus independently powered, and directly connected to the pi, no hub. No other USB device is connected, so I cannot really see if anything else is disappearing... Note that the filesystem is ext3, I see "mounted using the ext4 subsystem" in the log. Con...

Hi everyone, I have a headless ALARM pi sharing my music library via NFS, after a few hours my library becomes unavailable on the network. The library is stored on a (powered) USB drive connected to the pi. If I log on the server, the directory where the drive is mounted is not accessible, with inpu...

I finally managed to get my hands on the raspberry and I found that the problem it's quite different to what we were thinking: basically I have an external drive that is always connected and mounted at boot with the auto option on fstab. For some reason this drive is not always recognised at boot, i...

I've been experiencing this problem since last January more or less, now I'm determined to solve it since it's there also after a reinstall and is really annoying... I tried to configure netctl with a static IP profile, but the same still happens. I'll run fsck as soon as I get to have someone near ...

gaggio

Thanks for your advice, but the problem is not due to a different IP being assigned each time. My router has been configured to assign the same IP to the same mac address each time and the mac address of my raspberry pi is constant. This configuration works for every machine in my house. Currently, ...

And if you meant the raspberry serial number, that I get with cat /proc/cpuinfo, it's not made of all zeros

Sorry, clearly this question needed more details... - I recently installed a clean archlinux-hf-2013-07-22.img, but the same problem was there with the previous install, and the system is regularly updated - I don't have netctl configured, actually I haven't configure anything regarding the network....

Hi everyone! This question may not be strictly arch-related... Very often on reboot my headless raspi is not accessible via SSH even if it is booting fine (according to the status led). I usually need to unplug and plug the power several times before the network starts working. This obviously means ...

I finally managed to get my hands on the rasp:

The output of ifconfig is:

Code: Select all

Warning: cannot open /proc/net/dev (no such file or directory). Limited output.

While route -n gives me:

Code: Select all

/proc/net/route: no such file or directory
INET (IPv4) not configured in this system.

Thanks for helping me out

Finally connected to a display, I can just see the following errors: sh: cannot set terminal process group (-1): Inappropriate ioctl for device sh: no job control in this shell sh-4.2# Now the last line is indeed a command prompt, where I can actually input commands with root rights, even if I didn'...

Thanks pepedog,
Just did what you suggested, the device seems to boot now, with the LEDs on correctly. Still can't login via SSH (no response from host). I'll try to connect a keyboard and display to see what's going on.

Thank you

gaggio

Morning guys, I think i screwed something up during this update: after the bash update I can't login anymore... Before rebooting I noticed that webmin couldn't execute any command on the system with an error message like "can't find /sbin/bash" Is there any way to set it right, maybe putting the SD ...
