hi there,

i recently bough the vc-1 and the mpeg2 licences. now i am able to play bluray and dvd dumps with oxmplayer. however i do like the idea of shrinking the dumps a bit an convert them to h264.

so i tried to convert them with avconf with no success though. actually a simple conversion with no audio fails

Code: Select all
avconv -i bluerayinput.mkv -vcodec libx264 -an output.mp4
[...]
    Stream #0.0(eng): Video: libx264, yuv420p, 1920x1080 [PAR 1:1 DAR 16:9], q=-1--1, 24k tbn, 23.98 tbc
Stream mapping:
  Stream #0:0 -> #0:0 (h264 -> libx264)
Press ctrl-c to stop encoding
Killed   18 fps=  1 q=0.0 size=       0kB time=10000000000.00 bitrate=   0.0kbits/s   

(i didn't press ctrl-c)

Anybody around here who tried to convert / shrink blu ray dumps or dvd dumps (got mine from make mkv)

thanks

is this even possible? using the pi to convert VC1 to h264 in one step.

i'd expect it to take days even if it were possible, and a bit pointless buying the license if you're converting to h264 anyway.

you're not assuming that transcoding would be hardware accelerated like playback is are you?

true, but the whole story is to make a digital copy of a blu ray and then compress it a bit to save disk space. it feels much more safer to have copies on my RAID instead of them "not so much reliable" optical thingies. plus having a collection of movies on one device is far more like a real media center.

of course i do, since i have no clue at all. :) well i thought, having hardware decoding and encoding would turn the pi into a magic video converter. but that's not possible?

Well , if there is no software support , how should that work ?
You can try omxtx (the only HW accelerated transcoder ) ,
but IMHO that is more like a proof-of-concept.
