The data specifies the info you want to get/set from your car. Better to google for OBD-2 (OBD-II, On-Board Diagnostics) as I think that is what you are looking for. Also have a look at this instructable OBD-Pi . It mentions pyOBD. Looks interesting. Will have a better look at it. Sadly... I don't h...

Leider hat omxplayer keine Config Datei. Aber... omxplayer wird gestartet durch einem shell Skript: /usr/bin/omxplayer. Mit sudo nano /usr/bin/omxplayer kannst du die "-o alsa" Option hineinfügen. Regel 67 (ungefähr) wird dann LD_LIBRARY_PATH="$OMXPLAYER_LIBS${LD_LIBRARY_PATH:+:$LD_LIBRARY_PATH}" $O...

Die letzte Version von omxplayer unterstützt alsa:

Code: Select all

omxplayer -o alsa <movie>

The OP created issue #505 in the omxplayer repository.
Follow the link for more details.

Just out of curiousity, are you able to post a picture of your reader?

Found on the supplied link the Raspberry Pi IRI Host link.

Have you tried:

Code: Select all

omxplayer --display=5 file1.mov & 
omxplayer file2.mov

The ampersand & character placed at the end of a command line means that the command is run in the background.

To stop playing before both movies are played, use:

Code: Select all

sudo killall omxplayer.bin

Notice the .bin.

jehutting

Looks like you are starting up a new omxplayer as soon as you kill one; every omxplayer has different process id.

How does you script looks like or how do you start omxplayer?

@PeterO: OK... the OP can live with that...but where does that leaves me?

If you are still willing to post your full coded project, I am still be interested.

I have the same issue as the OP. I have several threads on watch, and none of them gave me an email. In the past I got some emails, but recently watched threads...none.

Untill today...I got my first email of an already long time watched thread. Seems to be I'm the lucky one of today

Yes you can. I guess that this is always the case when connecting hardware to the GPIOs. Interesting question as the RPI is an educational board and to be used by everyone, for noobs and not noobs. I don't know what the experiences are of people actually doing all these kind of stuff. How many of t...

Great the DAC board works also on my Raspberry Pi Model 2B. Hmmm...the BBCode [img] tag doesn't work?? https://www.dropbox.com/s/r4pm5lmmiqmgdy1/RaspberryPi2B-DACBoard.JPG The photo shows on the right side my Ground cluster. I only took Pin 39 (Ground) from the GPIO header to create this Ground clus...

Why do you want it for the Pi Zero as you already have such a nice board as the pHat Dac for it? I made the connections between the RPI and the DAC Board with Dupont male/female breadboard jumper cables. Using my breadboard for the resistor and creating a GND point. Will make a picture of it. Nothin...

Hi zipplet,

Maybe I'm not clear, but my DAC board (the same as the OP has) is up-and-running.
As it uses the same chip as pHAT DAC, the pcm5102a, it should be selected as 'hifiberry dac' in Volumio or other applications.

jehutting

@gixie: an 'up to date' Raspbian Jessie with omxplayer. Are you using Volumio? As it is a Hifiberry/pHat Dac compatible board it should work.. Could install and try volumio if you want me to check that. Whatever you (or someone else following this thread) want :) @zipplet: Can you please tell me the...

I have no experience with GTK+, but that shouldn't be a problem

It is better to keep the OP in mind. So @OP, what would/should it be?

jehutting

That would be great! To have a fully runnable code/application/example to get more grip on alsa sound, have a playground and as an extra bonus GTK+ code.
Looking forward to the code

jehutting

First, I'm not an alsa expert, just google'd around and found snd_pcm_drop should do the trick. However, there are also posts that the snd_pcm_drain should be in the non-blocking mode (with snd_pcm_nonblock or at snd_pcm_open ). Also found a post with the note that snd_pcm_stop() must be called in t...

I don't use or have a pHAT DAC. But I have a more or less compatible dac board. Try to run the following commands: $ aplay -l **** List of PLAYBACK Hardware Devices **** card 0: sndrpihifiberry [snd_rpi_hifiberry_dac], device 0: HifiBerry DAC HiFi pcm5102a-hifi-0 [] Subdevices: 1/1 Subdevice #0: sub...

Great... got it working. I didn't hook up the XMT correct to the 10K resistor :oops: . Apparently when it "floats" the board mutes and un-mutes (almost) randomly causing the sound to drop ( the block waved sound ). Updated my previous (/first) post on how to connect the board; re-wired it. Read the ...

Just googling around :lol: Updated my previous posts. The current status is that I'm stuck.. :( Running a speaker-test sounds like it is missing some samples in between. Instead of a monotonous sound...well...it sounds more like a block wave formed signal. Good thing is that the left test signal app...

Technically, your seller is right; it uses the I2S interface which is made by the 3 gpio signals BCK, LRCK and DIN. However, the other signals (SCL, FMT, XMT) needs to be wired. Will see if they are (so-called) pulled-down/up and have a default state. Update: * The signals FLT, FMT, XMT and DMP are ...

No, as I am using a Raspberry Pi Model B. This model has a 2x13 P1 connector and an additional 2x4 P5 connector. Are you using the same or a newer (B+/2B/3B/Zero) model? Nevertheless, I think using the adafruit or phat dac pinning (the i2s interface) with the additonal wiring of - the SCL and FMT to...

How much money do you want to spend? Sorry... sick joke! OMXPlayer has several (commandline) options for streaming : --live Set for live tv or vod type stream --avdict 'opts' Options passed to demuxer, e.g., 'rtsp_transport:tcp,...' and (but I'm not sure about them!) --audio_fifo n Size of audio out...
