Re: gstreamer h264 ts transcoding

Thanks Defiant, in the meantime I asked at gstremer-devel mailing list: http://gstreamer-devel.966125.n4.nabble.com/Help-with-transcoding-h264-encoded-TS-on-raspberry-pi-td4664013.html Seems there is a problem, quoting Tim Müller I think the problem here might be that h264parse does not put width/he...

gstreamer h264 ts transcoding

Hello everybody, I've been trying to transcode some h264 HD tv recordings in .ts to h264, just a bit lower bitrate than the original. Tried omxtx, but the results were not really satisfactory. Now with gstreamer 1.0 and gst-omx, it should be working, but it isn't. Transcoding mpeg2 TS to h264 works ...

Re: loosing connection to sensors...

I don't think it's too much, the 1-wire can span 100s of meters when done correctly (as I've read). What is the topology of the network? Linear, star, a mix? Could you perhaps test the network segment per segment (only one sensor at a time)? Perhaps we could rule something out... I have to warn you ...

Re: loosing connection to sensors...

The GPIO input is not 5V tolerant, so if you'd power the sensors from 5V you'd have to change the output of the sensor using some sort of level shift. I'd say check the wires... try with shorter ones. And check this http://www.maximintegrated.com/app-notes/index.mvp/id/148 Didn't read it myself, I o...

Re: GPIO +5V level

So I measured the voltages around the polyfuse. There is a drop of 0.10 - 0.12V over it, so I think that's OK. The GPIO gave me 4.88V yesterday when I measured and that should be quite alright. Maybe I need better grounding, as I've read it's critical with RF receivers. I'll look into it further. Th...

Re: GPIO +5V level

Thanks for the reply. I did try it, but it didn't work that way. It works when powered from external 5V source. Maybe I messed the wiring up, but I don't think so... Anyway, I'll retry and let you know. I've read the 5V RF receivers are particularly picky about the supply voltage. EDIT: Ok, I stand ...

Hi all, I'm getting only about 4.8 or 4.85V from the GPIO +5V pin. Don't know whether this was discussed here already, but I really need 5V there, because of the RF receiver I'd like to power from it. Now I know it could be down to the PSU.

Re: Software implementation of HT12E encoder

Hi and thanks a bunch. In the I meantime started from scratch. I realized, I could "scope" the encoder output using the raspi itself, so I switched the gpio to input and sampled it (I used a voltage divider). The output had some holes in it, due to the sampling rate, but I could confirm the data in ...

Software implementation of HT12E encoder

Hello all, I'm trying to make an RF mains switch with an HT12D decoder on the receiver side. I tested with HT12E on the transmitter side and all works well (no switching yet, just lighting up LEDs). But since the encoder takes parallel input, the number of required GPIO pins would be too high. I'd l...

I've been thinking about something similar, so far I'd like to build it with 433MHz transmitter and receiver, with HT12E and HT12D encoder and decoder. For the actual mains switching I'd like to use a triac circuit like this http://hmmtheresanidea.blogspot.sk/2008/09/triac-mains-switching.html . My ...
