Zdravim
Pred nedavnom som zacal pouzivat Linux Mint 16 Petra.
Rozbehol som satelitnu DVB-S2 kartu s tvheadend (backend) a xbmc (frontend).
Ide mi to celkom pekne, ale dekodovanie videa zjavne vykonava CPU.
Nasiel som nejake navody ohladom instalacie fglrx, ale nepodarilo sa mi to dotiahnut do konca (xbmc potom neprehravalo vobec nic).
Vedel by mi jiekto poradit, ako HW akcelerovat video cez GPU ?
GK mam ATI HD RADEON 4550
01:00.0 VGA compatible controller: Advanced Micro Devices, Inc. [AMD/ATI] RV710 [Radeon HD 4550] (prog-if 00 [VGA controller])
Subsystem: PC Partner Limited / Sapphire Technology Device e106
Flags: bus master, fast devsel, latency 0, IRQ 44
Memory at e0000000 (64-bit, prefetchable) [size=256M]
Memory at fdee0000 (64-bit, non-prefetchable) [size=64K]
I/O ports at ce00 [size=256]
[virtual] Expansion ROM at fde00000 [disabled] [size=128K]
Capabilities: <access denied>
Kernel driver in use: radeon
(xbmc potom neprehravalo vobec nic).spíš problémy konfigurace s pokusem to tlačit do té akcelerace?
CPU mam dual core 2.8 GHz a bezne SD videa zatazuju CPU cca 15-25%, ale ak prepnem na nejaky HD, tak je to az do 80% a po case sa zacne obraz rosypavat (neviem ci to sposobuje velke zatazenie CPU, alebo je problem v DVB-S2, ale to skor nie, pretoze vo win HD funguje aj hodiny bez zaseku)
Ako je vidiet ta moja GK neni nic moc, ale na PC sluzila hlavne na prehravanie videa (vlastne PC vyuizivam ako TV sat), zatail este pouzivam aj windows a tam to samozrejme HW akceleruje, cize pri prehravani aj HD mam CPU tak do 10%.
Takze jedina moznost je kupa novej nejakej invidia GK ?
ta situace bude opakovat pro veskery starsi HW , ale s touto kartou jede hw akcelerace videa s OSS ovladaci bez problemu
dmesg vypise toto
[ 1.372727] [drm] UVD initialized successfully.
Moment, ja ale citam, ze vdpau je urcene pre GK nvidia
Nenasiel som nejaky uceleny navod? Predpokladam, ze apt-get install vdpau asi stacit nebude (nie som taky zdatny a nemam v tom velmi prehlad).
chabu to vypisalo

Nainstaloval som cez synaptic mesa-vdpau-drivers a vdpauinfo vypisuje teraz toto, ale v xbmc nenama ziadny obraz, len zvuk a nikde nevidim, nastavenia pre video. A blbe je aj to, ze aj pri prehravani zvuku mam CPU na cca 30%

Instaloval som to cez synaptic a verzia je 10.3.0
hmm a teraz ako zistim aku ver. mam mesa
Skusil som aj mplayer ako uvadzas - nasiel som na HDD nejaky ts subor, ktory som nahraval uz davnejsie s DVB a tu je vystup

Skusam este podla jedneho navodu instalovat fglrx, ale po instalacii uz vobec nespustim xbmc (pise: Error XBMC need hardware accelerated OpenGL reendering. Install an appropriate graphic driver).
Nejak sa mi sakra nedari :(
Nainstaloval som nanovo mint 17 a hned mesa-vdpau-drivers + mplayer a spustil s konzoly
Tu je log prip. screenshot. Ono to funguje dobre, ale na vykreslovanie sa nepouziva GPU, ale CPU

mplayer -vo vdpau whatever.mkv
jj je toho na mna privela 
spustil som to s -vo vdpau, ale aj tak to neslo. No nic, skusil som si cvicne nainstalovat xbmc a testoval som to tam a ono to aj zacalo fungovat vid screenshts
http://postimg.org/gallery/8oa75u1c/
Ale zas mam dalsi problem s xbmc, neda sa vypnut :) HD kanaly uz idu celkom OK cez vdpau, ale nevypnem xbmc (jednoducho pri ukonceni zamrzne).
Och ja nestastny zemepan
btw MadCatX dik za podporu od teba, inak by som uz asi bezal kupovat nvidia kartu
