Problems with Pi Camera, files generated and file types.

I have a RPZ with a camera. I take pictures and save them to the SD card. Originally the files were .png and locally on the machine they worked in the program to view them. I then FTP them to another machine and they are corrupt. Looking at the files in the TERMINAL, I see them as purple files. Exis...

Re: VLC wont run properly (even after uninstall and re-install)

I know this is an OLD thread.

I recently had a similar problem.

My solution was (from the cli)

Code: Select all

vlc --reset-config
And it worked.

I am not going to say that will be the answer for you, but after a lot of messing around, it was for me.

Re: allow hot-plug wlan0

Forget the old commands "ifup wlan0" / "ifdown wlan0". Instead get in the habit of using "ifconfig wlan0 up" / "ifconfig wlan0 down". Or, to be entirely up-to-date, "ip link set wlan0 up" / "ip link set wlan0 down". These commands will make dhcpcd do something. I know it has been a while, but it is...

VLC now not working. It did work once.

Recently I had to rebuild my machine from Jessie to Buster. I got a new SD card and flashed Buster onto the card and went about getting things working. It is a headless machine, but the HDMI port has a HDMI- Composite converter so I can get audio output. That is then sent to the sound system for pla...

I am sorry to say I don't have a magic answer. I too am having problems with VLC. But for what it is worth, I would get rid of the bluetooth part. From the terminal also try this: amixer cset numid=3 2 Then try something like: sudo aplay /usr/share/sounds/alsa/Front_Center.wav And see if that plays ...

Headless RPz(W) weird happenings.

It has happened now a few times and I am not able to understand how to fix the "problem". My RPz(W) is connected to my WAP. (Linksys WRT 1900acs) The RPI is headless. Every 18 seconds - or so - it sends an "I'm alive" signal back to a central machine. A few times now I see the LED on it going crazy....

Re: allow hot-plug wlan0

I am sorry.

I have two BIG problems with the RPI just now.

I am getting them mixed up.

One is the RPz(W) not reconnecting and the other is a RPI (early version) suddenly not working with a new kernel being installed.

My head is all over the shop with it and I am sorry I mixed the two problems up.

Re: allow hot-plug wlan0

/etc/network/interfaces, ifup/ifdown, the "hotplug" keyword are all obsolete . Even in Jessie. What you want is the modern way of configuring network interfaces, which is event-driven: when an interface is brought up, an event is fired and dhcpcd configures networking (see /etc/dhcpcd.conf). When a...

Re: allow hot-plug wlan0

It is kind of difficult to try a different "card" on a RPz(W). The "card" is part and parcel to the machine. I really don't get the sarcasm - though I am from Oz. If that is the accepted way to talk to others, then it is not really of any help to anyone. If people know things and other people like m...

It is a headless machine and it (now and then) seems to lock up.
