xmbc-pvr + tvheadend = no crystalhd - mythboy - 2011-07-13 Hi all, I have an Atom 330 dual-core 1.6Ghz mobo. It came with a minipcie slot for the wireless card (which is pretty useless in Ubuntu 10.10). As an experiment I put a Broadcom CrystalHD card in the minipcie slot to see if video performance would be better than the embedded nvidia chipset. To my surprise the Broadcom chip performed slightly better. I played back my movies in XBMC and 1080p/720p was slightly smoother and slightly sharper than the nvidia chip. So far so good right? Well once I tuned into tvheadend from xbmc, all the channels would not use the chd-h264 driver but instead use the ff-h264 driver causing a lot of jitter. When I switch back to the ndvpau driver, I see the tvheadend channels properly use the ndvpau-264 drivers. Is crystalhd not supported in tvheadend? Are there any plans for support? - chrisjunkie - 2011-07-22 I had similar problems. Press i while trying to play live-tv - what is the audio codec? Here in New Zealand it's AAC-LATM and the ffmpeg integrated with XBMC currently doesn't like it at all (completely unsupported as far as crystal HD is concerned) so therefore defaults back to ff-h264. Cheers Chris - mythboy - 2011-07-23 the codec used is ff-h264. Movies, Youtube, all play chd-h264 (the crystal hd decoder) but tvheadend does not seem to support it. - opdenkamp - 2011-07-23 please pastebin a full debug log. crystalhd should be included in the builds. did you enable it in the video playback settings? - mythboy - 2011-07-23 Hi dushmaniac, real dumb question but how do I find the tvheadend debug log file. All I can find is the xbmc.log in ~/.xbmc/temp/xbmc.log - RoboSK - 2011-07-25 http://trac.xbmc.org/ticket/11496 + "new" info (old 3 months) - it seem as problem with deinterlace, if i recording HD channel with Tvh and then running (.mkv) into Windows+Media Player Classic H.C. then no video,only audio - normal 720/1080 rips works with cHD perfect... edit: Linux+cHD+XBMC+HD rip -> perfect - opdenkamp - 2011-07-26 mythboy Wrote:Hi dushmaniac,I didn't mean tvheadend's debug log, I mean the one you posted - jjhdtv - 2011-08-24 I'm having the same problems using live PVR with TvHeadend serving a HDhomerun. Standard definition stations play fine, High-Def do not. I'm using an apple TV with the crystalubunutu image. The *.strm HD channels from the HDHomerun play perfectly. Is there solution/ work around for this issue. thanks. - Gfunk117 - 2011-08-29 jjhdtv Wrote:I'm having the same problems using live PVR with TvHeadend serving a HDhomerun. One of the major letdowns the pvr addons have with crystalbuntu/ubuntu atm is that Live TV will NOT use your Broadcom cHD for hardware decoding, at least this is my case with addons xvdr and vnsiserver for a vdr master backend. Right now the only HD 1080 support is ffmpeg software decoding and this is not possible only 720p is possible but very high pc usage (90-100% in most cases). SD is just fine with a low pc usage deinterlaceer like "Blend" I believe NA Satellite Streams are in MPEG-4 Part 10 or AVC and the Crystal HD SHOULD support this format but it all comes down to the BCM Driver lacking implementation at the moment. Crystal HD codec specs: - H.264/AVC High Profile@LeVeL 4.2 up to 40 Mbps (NA Satellite Stream Codec) - VC-1 Advanced Profile@LeVeL 3 up to 45 Mbps - VC-1 MP@HL, VC-1 SP@ML, WMV9 - MPEG-2 MP@LL, ML and HL at up to 80 Mbps - DivX® 3.11, 4.1, 5.X, 6.X, XviD - MPEG-4 Part 2 SP & ASP - AVS1-P2 Jizhun Profile, Level 6.0 - ankn - 2011-08-29 The exact used codec should not matter: xbmc-pvr is able to exploit the crystal hd card playing the recordings of the vdr backend. - Gfunk117 - 2011-08-29 Now if we could get ffmpeg-crystalhd compiled (ffmpeg's make currently errors out for me at /usr/include/libcrystalhd/bc_dts_types.h:64: error: expected ‘=’, ‘,’, ‘;’, ‘asm’ or ‘attribute’ before ‘bc_bool_t’ with kernel 2.6.32-24-generic) then we could build xbmc-pvr with --external-ffmpeg. I have submitted an issue over at FFmpeg Github. If anyone can solve the make issue please post the fix.

May be try ffmpeg-crystalhd from philipl ? https://github.com/philipl/ffmpeg-crystalhd - Gfunk117 - 2011-09-02 cwalker Wrote:May be try ffmpeg-crystalhd from philipl ? Tried many times and make will error out. I submitted an issue days ago with no response. Davilla is gonna give it a shot tomorrow and help me debug the code. http://forum.xbmc.org/showthread.php?p=878622&posted=1#post878622 any working builds yet - mythboy - 2011-12-04 Hi Gfunk, Have you gotten a working build? I've recently placed with the openelec with pvr suport and those do have crystalhd support, but only for playback of videos. Livetv via tvheadend still use the ff-264-mpeg decoder not the crystalhd. - mythboy - 2011-12-24 Any updates on this? |
