I recently was made aware that ffmpeg can now decode DXA, is it able to encode to that format as well? If not, when would you expect it to be able to?

Jeremy Duncan · 15th October 2007, 23:28

The DTS doesn't work on AC3 output using these settings:
Link

Any suggestions ?
This is using FFDshow _XXL 1524

Somebody else reported this, I have no way of testing this.
It works using 24 bit output though

This thread is not about ffmpeg.

ffdshow currently does not support for neither decoding nor encoding of DXA.

ffdshow takes care of mp3 encoded audio in video containers. But I would also like to use it on straight .mp3 audio files.

WMP and MCE don't use DirectShow for .mp3 playback anymore, so it is not possible to use ffdshow.

Thank you, yamagata-san for implementing the Seb's color level filter. I didn't have to use it till I buy an ATI HD2400XT this morning. Using it with VMR9 (either windowed or renderless) and non-DXVA (yes with DXVA decoder like Cyberlink the color is ok) decoder I have washed out video. Now I have to either use the level filter with VMR9 or use Haali renderer (or use ffdshow's YCbCr <-> RGB but I don't like it as it use more CPU). The funny thing is all onboard graphic cards I have encountered all output the right color level. Wonder when they'll get it right?

No way to force them to use DirectShow?

Oh, that's what I tried yesterday. Uncompressed and LPCM cannot be set separately. I found another bug, "on sampling frequency match" doesn't seem to work.

It's a good news. Thank you for your work.

Not that I know of. Otherwise I would have already mentioned it.

I tested latest builds by xxl to check how much improvement is there in multithreaded h.264 decoding (tried on sliced and nonsliced). And it doesn't look like any.
Is the only mt version the one xxl posted some pages back, or all his newer builds have that, as I'm confused right now...
Thanks.

with ffdshow the specified frame rate is 30fps but at some stages the video drops to 15 frames with some stuttering but not frozen frames (only 3 of 32 buffers are used probably because it does not have enough speed to keep them fully used)

cpu usage goes from 30 to 65% with ffdshow/cyberlink and 30 to 85% with coreavc.
I changed the file termination from mov to mp4 to use haali splitter.
you can see additional av info from the haali osd if you use the haali splitter and renderer.

used MPC HC 1.0.10.0, latest haali, ffdshow 1485(multi-core patched)/1515, coreavc1.5,cyberlink h264 decoder. Pentium D 3.6GHz/6800gs 163.71

Kado, thank you very much for testing.
It shows that indeed there is a bug in ffdshow & h264 imo. (it's not using all the buffers, all the time, as it should??)
I'm experiencing the same problem with another MKV
filename: Freedom_Ep1_(2006)_[720p,HDDVD,x264,DTS]
At around 1 minute during the opening, huge stuttering or frame freezes with ffdshow.
Cyberlink in soft mode and coreavc are as smooth as can be on that sequence.
(using revision 1530, "queue" is disabled, "drop frame on delay" and skip h264 deblocking on delay" enabled or disabled don't seem to make any difference). CPU used max is 40% on my system during that sequence with ffdshow. (and with other filters that decode it smoothly btw)
It seems ffdshow is chocking on big bitrate jump or something..
See you,

TSR

You're kidding, right? No matter if something is licensed for some/your region or not, distributing content without the permission of the copyright holder is still 100% illegal.

np: The Orb - Ba'albeck (Orb Sessions Volume 2)

well sorry then, i'll remove the link.
Since it's not licensed outside Japan, i thought it wouldn't be a problem.

That could have something to do with the DTS track. It has been observed in the past that full-bitrate DTS at 1536kbps causes stuttering with certain decoders and movie players, and using AC3Filter set to pass-through usually solved the stuttering.

yesgrey · 17th October 2007, 00:38

@haruhiko,
The custom matrix for YUV<->RGB conversion is not needed anymore. I realized in my thread it does not work as I intended to. When I update my thread about it I will let you know.

Thanks anyway. The current YUV<->RGB conversion as you implemented should be enough.

Honai, thanks for your input.
I'm not sure the DTS stream is responsible as I use FFDshow Audio decoder set to "libdts" for all 3 tests.
(CoreAvc+libdts, Cyberlink+libdts, FFDhowVideo+libdts)
Only the test with h264 decoded by FFDshow has the issue.
See you,

Jeremy Duncan · 17th October 2007, 01:16

TheShadowRunner,

I've had somebody post that they had problems with the dts in FFDshow audio codec as well.

Maybe something needs to be adjusted to allow for dts through ac3 ?
Looking at your post, the problem with dts playback stems from the FFDshow video codec.

TheShadowRunner,

Can you please follow this suggestion from leak and post the results.
I would, but I can't since I don't have the equipment or knowhow as a result.
Just play the dts using the FFDshow audio and video codecs, the dts that has the problem, and run debug.

hmm sorry Jeremy but
1. i don't use avisynth.
2. i don't use MPC
3. the source is not DVD

Besides my problem is not related to DTS, i don't think, but in the way ffdshow decodes h264.
o_O
See you,

TSR

Jeremy Duncan · 17th October 2007, 02:09

TSR,

I see the problem you have is when you use dts in the ffdshow audio codec?
And when you use the ffdshow video codec, for h.264.

I have the same problem, but in the ffdshow video codec I use the mpeg2 dvd decoding.

Maybe the problem your seeing is related to the problem I'm seeing in some intrinsic way.

Ha ha ha.

I dunno.
