How does omxplayer seek work?

I am building my own version of omxplayer with playlist capabilities fed via a playlist file like so: startTime,FinishTime,path startTime,FinishTime,path startTime,FinishTime,path ... I noticed that the times it starts at are not exactly the same as what I specified, so 110 seconds in might turn int...

Successfully synchronized omxplayer across multiple raspis

http://i.stack.imgur.com/1MNVU.jpg I have been at this for months, I tried everything, including Turing Machine's omxplayer python script , but none of them were reliable. So I rewrote omxplayer to use tcp communication to 1) Start at exactly the same time 2) continuously update play speeds in a ma...

Re: Multi Speaker Home Audio system

I created a version of omxplayer which can synchronize movies and although I have not tested with audio, it stands to reason it should work. Please go check it out and let me know of any potential bugs

Re: OMX Player (or similar) Frame Sync

Is there a way to have an external (or master) sync signal fed to OMX player for multiple (network connected) R-Pis running OMX Player, so that the videos can be frame synced together? There are two types of synchronization, and they use the same name to describe their process, so it is obvious why...

Do you, or anyone else find that profitable? I get the feeling like you need to buy more raspis/ASICs to make it profitable, but then you just have more of an investment.

Re: Serious problem with raspi-update

On a card corrupted in this way, you can't dump a file from it. Can you dump more than 6.5GB onto it? Essentially: you have demonstrated that you are unable to read. Are you also unable to write? I can write to it, and I do so regularly; when the SD card becomes corrupted, I simply overwrite it wit...

Sorry, it just doesn't add up. DD does not care about your filesystem. It should work regardless of what's on the card, unless the card is really truly messed up. Yes it is really truly messed up after every rpi-update Your filesystem could be random junk and corrupted data, dd would still work. I ...

Re: Serious problem with raspi-update

rpi-update or raspi-config? Either way, neither of them do anything that would corrupt the sd card other than write to it. Which could mean you have a bad power supply or terrible luck with sd cards.

I have noticed a serious problem whereby raspi-update corrupts the SD card.

Re: Can/should the raspi control 100+ LEDs?

Dimmable is generally not a term used when describing LEDs (actually, I suspect it's not a word at all). This is the only one I found that claims to be dimmable.

Re: Can/should the raspi control 100+ LEDs?

If all the LEDs should do the same, you don't need a GPIO pin for each strip. You can just use buffers, which send the same signal from one GPIO pin to all the strips. I'm currently working on a project where one pi will control about 3500 LEDs, each individually, through one pin ;-) But that's ano...

Re: Can/should the raspi control 100+ LEDs?

Just make sure you have adequate power to cover them - obviously not directly from the Pi ;) Texy I guess my question is how do I connect it all to the raspi? Do I use a solid state relay? I mean there are only so many pins on the Raspi and due to distances it might be impractical for me to connect...

Can/should the raspi control 100+ LEDs?

I just ordered 50 LEDs and I want to begin experimenting with them on the raspi (specifically boblights ). I imagine it is pretty straight forward to do so, as you connect two pins from the LED strip to the GPIO pins of the raspi (as per these instructions ) and then presumably control them via soft...
