Re: Omxplayer massive cock up

Nowhere does it say that 'apt-get update' and 'apt-get upgrade' need to be followed by a firmware upgrade. The person who put that version of omxplayer in the repository messed up. Even if you do upgrade the firmware omxplayer does not work in the same way and can crash the screen when it finishes p...

Omxplayer massive cock up

Omxplayer no longer works. Anyone who innocently does a 'sudo apt-get update' followed by a 'sudo apt-get upgrade' will find that omxplayer,. which worked before, no longer works and will crash your desktop. Even if you do a firmware update it will still not work correctly. I don't know how many Pis...

Yes this is a well known problem which has still not been fixed. Mixing high speed and low speed devices doesn't work unless you force everything to be lo-speed.

You can get a HDMI to VGA+analogue audio converter for about 22GBP. from Ebay.
Don't be tempted to buy cheaper HDMI to phono cables that are not converters.

obcd, have you tried the latest firmware and kernel? The output quality of the integrated analog output should be greatly improved!

The Pi is designed as an educational project to help interest children in learning to program.

The WD media players you mention cost 2 or three times as much as a PI and even they can't play ...

Re: H264 performance & VLC

I don't think VLC supports H264 or mpeg2 decode or encode either.
Omxplayer supports H264 decode and mpeg2 decode (if you have
bought a licence). I don't think there are any programmes that support
encode at present.

Did it ever play mp3 files. I know it plays mp4 video files and mp2 video files if you have
purchased the mp2 licence but has it ever played mp3 files.
Use 'sudo apt-get install vlc' to install the vlc media player. This plays mp3 files.

Re: omxplayer - GPU enabled video player

Omxplayer will play mp4 and (if you have purchased the mpeg codec key) mp2 files.
It won't play the sort of files you have, Why did you think it would? Convert them to mp4.
This is a very basic, very cheap computer not a media centre.

If your pi is running out of memory and crashing it may be destroying the partition table. This will make it appear that the sd card is completely dead. That is nonsense. If the Pi runs out of memory, the kernel will page to swap or kill processes. Linux knows the difference between swap space and ...
