let's improve ffmpeg together !
==================================================================== https://roundup.mplayerhq.hu/roundup/ffmpeg/msg3397
A few notes: Bug reports are very important. Reports about bugs in H264 are especially important: H264 is an important codec, and it might not be so much tested, since it's newer than most other important codecs. So, reports about wrong decoding (of valid streams), crashes (both in valid and invalid streams) and of misdetection (both in valid and in corrupted streams) are important and very helpful. Reports about A/V de-synchronisation are also very important, if the stream was tested on a fast enough CPU core an a fast enough computer (very difficult for H264 HDTV streams)

If someone doesn't want to send bugreport to ffmpeg bugzilla. you can send the problem h264-sample to me (no more than 10 MB). I will resend it to bugzilla

Bah! After being trashed by Michael Niedermayer on the FFMPEG list after mentioning bugs with PAFF interlacing and uploading test content etc that never seemed to be even acted upon, I don't see why anyone would be interested in helping the ffmpeg devs!
Anyway, I have moved to Reel Multimedia's eHD card in my VDR box ... which is nice. I might write up my experiences on it thus far if anyone is actually interested. There's not much English chat out there on this card, mostly in German on vdr portal and reel's own portal.
Cheers,

Yes, some not (yet) German-speaking VDR-amateurs, like myself, would definitely much appreciate your insight in relation to this card, including possible guidelines/advices/tips on how to make it ‘best friend’ with the current VDR development version. I think, for example, as a possible option, it could be helpful to see comments based on one of already existing (but probably outdated) German wiki’s, which would, at the same time, save volume of corresponding write-up.. Anyways, thanks in advance for sharing your experiences with this card!

This may happen to be a ‘bonus’, but cannot be reasonably expected, as 1080p output is not listed in the card’s technical specs. Nevertheless, provided the existing alternatives, this card seems to be very attractive for possible HDTV solutions. _________________________________________________________________ Invite your mail contacts to join your friends list with Windows Live Spaces.

I am trying to "hack" the ADB-3800 IPTV Box.
http://www.adbglobal.com/?q=node/187
I have managed to "inject" my own H264 streams (1080i, HP@L4) into the box, and the box played them without problems on my FullHD TFT using the HDMI output. AC3 Audio worked also over the SPDIF/TOSLINK interface.
According to the specs the box can also decode VC1, but I don't have a software which can stream a VC-1 TS stream to the box.
Any ideas on what software I can steam VC-1? I have used VLC for h264 streaming, but it does not work with VC-1.
This box can be obtained from eBay, starting at 40 Euro.
Maybe this can be a good alternative for the eHD card.
Regards, Artem
I have sent to them several samples in Septmeber :)

yes, it's really intersting. Please, don't modest :)

2008/10/7 Goga777 goga777@bk.ru:
Well... Michael at ffmpeg sometimes can be somewhat of an ass. That's life. And yes, he is rude! That's the "works for me" feature present in almost all free software.
Most importantly: ffmpeg supports a huge amount of codecs and h264 PAFF is just one of them (a variant, at least). Sure, some h264 content doesn't play right. Is it important? Yes. To me h264 PAFF is important. I live in Europe, so...
Now to the eHD. I've already owned some cards that proposed to do similar things. Not on HD contect, but similar. And I can tell you that a software solution is almost always better. Here's why: evolution. Software tends to evolve faster that hardware. And hardware, after you bought it doesn't change. Software can be further developed.
With this in mind I think that a perfect - almost - solution is GPU assisted HD decoding. And for that I must hope that ATI and Nvidia keep their roadmaps and launch those long-desired drivers. Just think about it. You can play, decode and encode with the same card.
Now, I have been working and tweaking with ffmpeg, trying what Goga posted at ffmpeg bugtracker and ended up with the same results. Some HD content play is broken. But most things work fine. About 98 DVB-S and DVB-S2 channels present on my vdr box play just perfect.
Also on news (don't know how trustworthy the source is but..):
So I am holding my decision (eHD, ATI, Nvidia) for a couple of months more. I've been experimenting HD since 2003, so I am patient..

I agree. I have relatively recent ATI and NVIDIA cards to test. I'm gonna wait for a software based solution to my present hardware. Spending an extra €150 on a new card that *just* decodes HD content is *not* in my plans. Meanwhile, I agree with Goga: we should report the bugs and more feedback to ffmpeg bugtracker. They have other developers other that Michael and most of them are nice, polite people.

Hi Morfsta, I would definitely be interested in 'Comparing notes'. I have bought an eHD card too, and got as far as having video out both the hdmi and s-video connector, but cannot, for the life of me, have both audio (analog and dolby digital) out, either on the dedicated eHD output pin, or in the motherboard sound card. I also tried choosing audio out over the hdmi connector and buying an HDMI audio/video splittre, but with that route I get no audio at all.
I tried looking for some documentation but, sadly, it doesn't look like it exists, and the forum are all for German speakers. I also tried looking at the plugin code but there are no evident comments, and the only parameter I was able to play with was the AC3 one, that causes either only analog or only digital audio to be output over either the sound card or the s/pdif out of the eHD card.
So far, I haven't dedicated a lot of time at the issue (I still have everything in my vdr test machine, and have another one perfectly working ;) but I would really like to dig a little bit deeper into the issue
Cheers

Ati's roadmap: http://www.techpowerup.com/71277/AMD_Software_Roadmap_Surfaces_HDCP_Content_ in_Linux.html
Let's hope those "OEM only" drivers are repackaged soon to more general usage. I hope Nvidia answers with similar features on their drivers. I just hope that they both make possible to use 50.000000000000Hz refresh rates on driver.
So I am holding my decision (eHD, ATI, Nvidia) for a couple of months more. I've been experimenting HD since 2003, so I am patient..
