Re: h.264 vs. vc-1 performance

I'm using omxplayer...latest apt-get upgrade and rpi-update from yesterday... But I assume omxplayer is here the resource hog when feeding the GPU with the video streams... I will update the blog posts with more details then... Also I'm currently testing temperature plots versus different CPU speeds...

snmpd.conf exec -> VCHI initialization failed

Good morning For some testing I want to display Cacti graphs...especially for logging the temperature I have a small wrapper shell script which executes "/opt/vc/bin/vcgencmd measure_temp" But when I want to get the data via SNMP get it returns: .1.3.6.1.4.1.2021.8.1.1.1 = INTEGER: 1 .1.3....

Re: h.264 vs. vc-1 performance

Testing raw NFS performance now and collect stats via Cacti... Looks good...Cacti shows an average bandwidth of 85MBits/sec with 98MBits/sec peak ;-) CPU load is around 30 - 35% (cat file > /dev/null and kworker together)... Any news regarding VC-1 performance and why framerate without audio track i...

Re: h.264 vs. vc-1 performance

Just ripped the dark night without any audio tracks...so only the VC-1... SNMP stats show me a streamrate of approx. 24MBits/sec and a CPU load of around 40 - 45%... The video doesn't hang anymore...but plays with a much lower framerate of around 8 - 12 frames/sec... root@raspberrypi:/mnt/Video/movi...

Re: h.264 vs. vc-1 performance

What uses less resources for accessing a movie? Playing via NFS? Or playing via local USB harddrive? Or playing via SD card? But so far since the latest firmware update I'm really impressed by the performance...before it wasn't able to play back h.264 over 15MBits/sec (o; I still haven't put my popc...

Interestingly Planet Earth, which is also VC-1, plays nicely...no stuttering on the episode 1 with the thousands of birds flying on the screen...peak stream rate around 40 - 50MBit/sec ;-)

h.264 vs. vc-1 performance

Just wanted to raise a quick question what other people get out of their RPi regarding performance of h.264 vs. VC-1... For me it plays smoothly a BluRay RIP of SPiderman 3 via NFS without stuttering (and software AC-3 decoding), whereas a BluRay RIP of The dark knight hangs every few seconds (VC-1 ...

arm_freq ignored? (solved)

Good morning...

When I set in config.txt the lines:

Code: Select all

arm_freq=1000
core_freq=500
sdram_freq=500
over_voltage=6
I always see with "cat /proc/cpuinfo":

Code: Select all

Processor	: ARMv6-compatible processor rev 7 (v6l)
BogoMIPS	: 697.95
Does the Arm CPU has some sort of dynamic clock adjustment?

Re: Hardware DTS decoding

Important question for developers Rpi. DTS/AC3 hardware decoding is possible in Rpi??. Yes it is. All ready to go for omxplayer and xbmc. Unfortunately DTS requires compliance testing before we can licence it. We're investigating that. Hmm...All ready to go on omxplayer and xbmc means they would su...
