Re: Audio/Video sync issues with omxplayer

anyone who wants to try sam nazarko's solution that will find that the OMX folder at the subversion repo does not exist anymore. you can still get it this way: svn co http://svn.stmlabs.com/svn/raspbmc --revision 1685 ./rev1685 and then change to this: for patch in $OMXPATCHES do cp -f ./rev1685/pat...

Re: ffmpeg settings for omxplayer

audio sync problems are still an issue if you are using the composite video (yellow plug) instead of hdmi. if you route the audio over hdmi then the sync problem "should" disappear. your ffmpeg command looks "ok". this is what I use for onepass: ffmpeg -i source.mov -c:v libx264 -profile high -c:a l...

Re: Gstreamer 1.0 for raspbian

wow! you're right. I was using videoconvert in my pipeline - which drops out. your video-only pipeline works fine at 720p - but still has framedropping issues at 1080p. (although this could be because of my slow SD card...) here is my pipeline with audio: gst-launch-1.0 filesrc location=big_buck_bun...

Re: Gstreamer 1.0 for raspbian

i can confirm that it eglglessink is now "working" without X, but seems to be framedropping to keep up. it is definitely smoother, but by my estimate around 15fps. still not on par with omxplayer, but is starting to get better and better. :)

your best bet in this case is to use rsync. http://www.cyberciti.biz/tips/linux-use-rsync-transfer-mirror-files-directories.html i do have one warning for you, and the solution i presented is not even perfect in a perfect world, because you WILL have SD cards fail on you sooner rather than later, es...

that's easy - just track down the pid of the autoloop.sh and kill that. use: $ top once you have found the pid like 1898 press Q and then enter $ sudo kill -9 *_pid_* DO NOT TYPE THE $'s -> they are just there to show you the command line, and DO switch *_pid_* with whatever pid is associated with t...

no - no stuck video. and once it ran it just ran... the installation went for 19 days straight. when the show closed in the evenings we actually just turned off the video projector and amp and left the RPi running. the nice thing about these kind of scripts is that if you lose power, as soon as the ...

Re: seamless looping

Raspberry Pi is a great way to "get your feet wet" in the world of programming. Indeed, that is why it was developed - to offer the public a low-cost alternative to learning programming and using embedded computing. As an artist and curator myself, I appreciate the low cost and flexibility that RPi ...

secondly, $'\302\240' is another name for nbsp (non-breaking space) -> which tells me you got some kind of problem with your encoding, you probably are not using UTF-8...

Re: seamless looping

sure - they'll play and loop, just follow the instructions here:

(and use an HDMI -> vga adapter)

and feel free to PM me if you have any specific problems.
good luck.

Set video output window size?

Hi, I noticed on github https://github.com/huceke/omxplayer that there now seems to be a way to tell omxplayer what size the video output should be. Does anyone have more information about this? The git push comment was "Add command line option to set the video output window" Thanks for any tips.

Re: seamless looping

i am an art exhibition engineer and needed to use the RPi to loop a 1080p audio/video installation. it had to be idiot-proof - i.e. autostart (on powerup), the sound had to be synced and it was not permissible to display any type of logging. sounds trivial, and it is. here is what iu did: 0) during ...
