FFmpeg/Mplayer supports E-AC-3 format now...

[rack04]

Where can i download the latest ffmpeg with latest patches?

[uberjay]

Yes and me too. The new audio formats require way more bandwidth than spdif. I'm considering getting an a USB sound card with individual 5.1 output - I have an old receiver without HDMI. 1080 is already asking alot (too much) from my system.

Yup. I finally broke down and hooked up the analog cables from my HTPC to my receiver's external inputs. It makes me sad to have this fancy receiver, and not use its decoders, but with this setup at least I can enjoy the higher bitrate audio formats. :)

Hi,

Here is the updated eac3 patch which apply and compil fine against the latest mplayer svn revision :

See you,

Hi

I patched an updated svn mplayer build, with the new v5 patch. Everything is ok, but I still have problems with no EAC3 sound.

I have come to the conclusion that I also need an updated and patched ffmpeg.

I'm running Fedora 7.

is this correct?

Need a win32 build in order to fix the pre-noice processing issues mentioned before.

That's not correct. mplayer's svn includes the ffmpeg svn sources. This eac3 patch is an ffmpeg patch, but you can apply it to both straight ffmpeg or the ffmpeg contained within mplayer.

What command are you using to play the video file, and what does the output look like if you add a -v?

[qubic]

This is 12Monkeys, with english and french DD+ soundtrack, plus a commentary DD track.

What command can tell me which is which and what format?

Also having the same trouble too. I'm pretty tired, have I forgotten something?

It is now just ffac3. The E-AC3 decoder was merged in with the AC3 decoder.

[skygod]

thanks for that, small things like that are tough to find! Working beatifully.

I documented the process in the Linux forum. http://forum.doom9.org/showthread.php?t=133901

Thanks alot. Now it's working fine.

I'm running a Sempron 3400, with 2gb ram.

I needed to start only the X server with "xinit" and do some framedropping. It looks and sounds really good.

[fenton06]

Does that mean we no longer need to apply any patches? We just install the ffmpeg SVN and should be good to go?

Also, where is the codec.conf file that is supposed to be modified?

EDIT: Found the codec.conf...

EDIT EDIT: Still need to apply patch...

Did you tell mplayer how many fps to use? Virtually all of the films want -fps 24000/1001

(I think ... are films shot at true 24fps if so, is the content on the discs 24000/1001?)

[fenton06]

yes...I did...it is 29.970 fps....but I will try to use that and see what happens...

EDIT: the 24001/1001 worked! Everything is working fantastically :D:D:D:D:D:D:D:D

[fenton06]

nevermind....

[sl1pkn07]

[fenton06]

ok, now when I am playing back files that previously worked flawlessly, they are now stuttering and I keep getting
pts value <= previous

I am using the latest mplayer svn, using the eac3v5.patch

any ideas?

[madsend]

Try using the option '-no-correct-pts' and see if that smooths out the video.

Using this option may cause A/V sync problems, but it may also get rid of the jerky pauses on playback.

update eac3 decoder to work with ffmpeg-svn r12191
To be honest, I didn't do much to it. The window generation function moved to mdct.c so it needed to be removed from ac3dec.c. Also, I wanted to update it so I could continue doing real work to it and stay up-to-date with ffmpeg.

[nautilus7]

Any news when 7.1 ch e-ac3 decoding will be ready?

OK, thanks.

Any idea on how to get an 8channel LPCM stream onto the HDMI audio out on chipsets that actually support true HDMI audio? What about the pure bitstream? Thanks.

Dustin

Update - The only currently available chipset that supports 8channel LPCM is the Intel G35. The upcoming Nvidia MCP7 series and Intel G45 will also support 8channel LPCM, however they say that they won't support Bit Stream passing.

I don't see what this has to do with FFmpeg and E-AC3... Maybe you should post this in a different thread?

[fenton06]

is eac3 ready to be implemented without having to apply a patch yet?

[jruggle]

is eac3 ready to be implemented without having to apply a patch yet?
Ready? yes. Done? no. It's a matter of me finding the time to prepare all the patches (for FFmpeg inclusion it can't be just one big patch)...then getting them reviewed...then making any corrections. But I will find the time soon. The new Google Summer of Code process for '08 is starting already and I want to get this project from last year off the books, so to speak.

[fenton06]

aha...fantastic :D

hi,

i used ffmpeg preset in first page to do some encodes from eac3.
i did some different aac and ac3 encodes, 2ch and 6ch...but i noticed that the voice audio channel results very low...instead if i listen the source eac3 stream it is ok...is there any setting i have to use in ffmpeg?

thanks!

both + a quick fix to enable the pipeline for the NeroAAC encoder.

[sl1pkn07]

thanks ;)

[jruggle]

Just to update everyone. Work on E-AC3 is ongoing. Right now the original author of the decoder from last year's Google Summer of Code is picking up most of the tasks required to get it finalized and into FFmpeg. Here are some details:

http://lists.mplayerhq.hu/pipermail/ffmpeg-soc/2008-March/002742.html

FYI the 3.6 patch is badly broken....

I will now try to compile w/o the patch and see if HD works w/o the patch...

I am using r26256 with eac3 patch in Max OS X Leopard and it works great :) thanks alot...
However i had trouble watching HD Material with DTS-HD Master Audio (7.1)
(i have libdca installed dont know if it makes a difference)

I found a patch adding the id 0x86 to demux_ts.c however after some hours on google i found out that the DTS material uses 0x86 AND 0x85 as id's. Then there was sound :D

So changing ./libmpdemux/demux_ts.c to:
case 0x8A:
case 0x82:
case 0x85:
case 0x86:
pmt->es[idx].type = AUDIO_DTS;
break;

hi,
what about the very little "underground buzzer" occurs after a conversion from E-AC3 ?
happened only from E-ac3, converting both to aac and to ac3...

[jruggle]

hi,

You're going to have to be much more specific... I don't have any issues with "buzzing" in the samples I have tested. Please give more information, and provide a sample if you can.

[pchangover]

I think I know what Gannjunior is talking about. Whenever I try to encode e-ac3 to ac3 with ffmpeg (with e-ac3 support) I get an ac3 file with static in the left channel.

Here's my console output:
http://img187.imageshack.us/img187/5208/ffmpegvb2.jpg

And a sample:

Ok, well I definitely hear the noise, but I am not able to reproduce the problem. What I really need is the original E-AC3 so that I can diagnose what exactly is causing that output.

Also, that appears to be an older version of the decoder... The newest version does not distinguish between ac3 and e-ac3 in the console output. So please update to latest SVN and try to duplicate the problem. If you still get noise, I definitely would like a clip of the source EVO.

edit: by latest SVN, I mean latest from the mplayerhq/soc repository, then run the checkout script to automatically get the corresponding FFmpeg SVN version and patch it.

[pchangover]

Ok. I tried to re-build ffmpeg from the latest SVN, but I think I'm missing something. Heres what I tried:

C:\Documents and Settings\Sean Turley>svn checkout svn://svn.mplayerhq.hu/ffmpeg/trunk/ ffmpegEAC3

Then I downloaded: http://kurtnoise.free.fr/misc/ffmpeg_eac3_mlp_r12588.patch
I copied it to the same directory

Applied the patch:
$ patch -p0 < ffmpeg_eac3_mlp_r12588.patch

Ran configure:
$ ./configure --enable-memalign-hack

Ran make:
make

then installed:
make install

When I try to use the newly built ffmpeg is doesn't have eac3 support. I know this is a n00b mistake but it's just easier to ask sometimes than to spend hours figuring it out on my own.

On a separate note, is there a way to trim an eac3 file? If so let me know so I can make you a sample.

:thanks:

[jruggle]

Ok. I tried to re-build ffmpeg from the latest SVN, but I think I'm missing something. Heres what I tried:
It should be easier than that if you have msys installed.

svn co svn://svn.mplayerhq.hu/soc/eac3
cd eac3
./checkout.sh
cd ffmpeg
./configure --enable-gpl --enable-memalign-hack
make

Hope that helps.

[jruggle]

Honestly, I forget how to do that in Windows as-is. But I know you can download dd (http://www.nu2.nu/download.php?sFile=dd.zip) , which is the same program I use on Linux for that purpose. I don't know... msys may even come with dd already...

[pchangover]

ATM I feel pretty dumb. I've been working feverishly to get eac-3 decoding to work in windows that I failed to realize that I could just restart and boot into Ubuntu and do it much more easily.

jruggle I initially tried your code in mingw, it didn't work, it just hung. Then the lightbulb turned on and I booted into Ubuntu. I installed svn and tried your code again. Worked like a jif. Now I'm encoding my .evo. If it doesn't work I'll post a sample for you.

Thanks for the help!
