MBAFF interlace support

dazed&confused · Postby **dazed&confused** » 12 May 2006 01:10

So, the BBC HD trial is using H.264 encoding and is aparantly MBAFF interlaced. It seems that only MainConcept / Elecard and Cyberlink AVC decoders work at the moment. VLC doesnt which leaves me unable to view them on a mac. Would be great to see some of the Planet Earth series!

And another. Its driving me nuts that the BBC are going to broadcast the world cup in HD and I won't be able to watch !

Yet another request for MBAFF support. Please.

ffmpeg added support for this (i don't know if they commited it in trunk yet) a few days ago. It will be available in the next version of VLC.

When I try to play something, it shows the first frame, plays the sound then crashes??

Try the daily build, it still stutters a lot for me (AMD64 4000+) but it works now.

Sorry, On OS X with 2GHz G5. There is no newer version

what kind of streams are you playing ?
BBC HD MPEG-4 streams ?

Yeah, the Planet Earth h264 BBC HD Streams. So far the cyberlink decoder makes the best effort at it (manages about 20fps max so far for me), particularly if you use purevideo and a supported nvidia card (which I don't have unfortunately). I just hope that VLC gets better at it, as I hate mucking about with different players for different video types.

Just tried playing a clip with this from the BBC HD trial on my Dual Core Intel Mac Mini (1.6 GHz). The audio is ok but the video was virtually frozen 2 - 3 frames a minute. CPU utilisation was ~ 108% (of 200).

I tried it too, with my 3.0ghz northwood. Virutally frozen, though cpu utilization wasn't past 60%... I gues the inclusion of what's needed isn't entirely there yet. I'm glad I found this forum though. I was going senile trying to find out why NOTHING (nstantmedia with pure video, cyberlink, nero showtime, wmp etc.) will play these bbc clips. I can't wait for the newer coreAVC to come about (or VLC). That'll solve our problems, I HOPE!

eh? I thought pure video only supported mpeg2 (gpu acceleration). I have pure video and this sucker will not play. Though, I'm running a agp 6800. Do the newer cards support mpeg4 acceleration then?

Tested with PowerDVD 7 and the H.264 support for the ATI Radeon X1x00 series. Works for me, not perfect but I'm using a x1600 and those are "rated" for 720p, I would need a x1900 according to ATI for 1080i/p

from there you can Check what you NVIDIA card supports with purevideo.

Dear all,
BBC, Free ... HD tests are bloming with the sports events. The Football WorldCup comming will certainly see the HD boom !

VLC-FreeHD test done on Rolland Garros, has shown that VLC is very power full but required a extremely powerfull machine to run a 1080i deinterlacing because no hardware acceleration is used

My request is to support DXVA so that hadware acceleration technologies like PureVideo for instance will be used when running VLC.

Doing so, we would also benefit from the all hardware features (like deinterlacing) that will be able to run on <3GHz processors.

This is a must do to have high quality for 1080i HD stream on today's machine IMHO.

Best Regards,
TM

Again there are three problems, DXVA is Windows only and there ain't Windows only developers.
And purevideo is pay software. You can call NVIDIA how to get hardware acceleration and they try to headshot you with old riva tnt cards. If you somehow succesfully complete the operation do same for ATI.
Then post those API's or sourcecodes to net. You have something like 2 days to complete your work if you would like to watch first WC match from telly, assuming VLC dev could patch code in a day and you would download nightly build.

In reality, it ain't happening anytime soon, so please don't come here to whine about things that can't happen overnight.

Meanwhile you can try mplayer with
-vfm ffmpeg -lavdopts fast:skiploopfilter=all
commandline parameter.

Been recording some raw BBCHD streams today directly on my Dreambox or via VLC but they just won't play via VLC or PowerDVD7 although a sample BBCHD sample I downloaded does. Anyone know if the BBC have changed the way they broadcast ?

dionoea · Postby **dionoea** » 09 Jul 2006 00:06

VLC 0.8.5 might not be new enough to decode those. Try using this build instead: http://downloads.videolan.org/pub/video ... ng/freehd/

Seconding this. MBAFF support would be awesome. The only decoders that I'm aware of that currently decode the BBC stream are Elecard and Cyberlink/PowerDVD, both of which are kinda slow.

I ran PowerDVD and VLan: both run into trouble running BBC's 'Planet Earth'. Jumpy video and sound.

System: Videocard NVidia GeForce 6600GT. CPU AMD Athlon 64 3000+ (1.8 Ghz). 1GB DDR-SDRAM memory. HD Seagate Barracuda 7200.10 320GB SATA2 16MB 7200RPM.

Anyone got a tip?

Any progress on this? I'm on a mac and there are no commercial MBAFF H264 decoders for macs as far as I can tell so MBAFF VLC is my only hope
