MediaCoder - universal batch A/V transcoder - putting all things together

[stanleyhuang]

MediaCoder is a free universal audio/video batch transcoder with a well-designed extension mechanism to support different audio/video devices (including file transmission to device, still under dev). MediaCoder supports most major audio/video/container formats and most valid combinations of them.

Hey,

1/ Cross-Posting is bad...
2/ Why did you use FFMpeg *and* Mencoder whereas they have the same libs ?

[Sirber]

is it me or I've seen this before?

Just something I came across for your #2 during my lurking and searches.

Because MEncoder and FFmpeg both have some feature the other doesn't have. For example, MEncoder can't handle multiple audio stream but FFmpeg can while FFmpeg isn't able to decode as much formats as MEncoder.

I just saw lots of threads about MeGUI, or I've just come to the home of it?

0.5.1-r8 is out


maybe a good thing when there is a new release is to edit the first post of the thread and add a line on the top (last version: 0.5.1-r8 (20 dec 2006), so anyone that opens this thread for the first time knows wich is the last version

[Fluffbutt]

When I press the buton 'settings' it just shuts down.

Same thing happens when I pres the buttton in the picture tab - resize.

[DarkZell666]

Nice to see that the project is still being worked on !

I didn't manage to do everything I wanted last time round, I'll give it another try soon :)

[Razorholt]

Stanley,

Why MKV format output a 25fps clip although I specified 23.976 in the picture tab?

Thanks,
- Dan

[DarkZell666]

Version 0.6.0-pre10 is out.

The changelog is massive since 0.5.1:
http://mediacoder.sourceforge.net/wiki/index.php?title=MediaCoder_Changelog

Download latest version here: http://mediacoder.sourceforge.net/dlfull.htm

@Razorholt: dunno what version you tried, but It might have been fixed since.

[DarkZell666]

Huh, not very impressive if you ask me, every attempt I made at encoding aac+h.264 in mp4 crashes mencoder and mediacoder all together (at least in the latest dev version). I'll try other combinaisons but I think I'm not gonna like this thing ...

Edit: it seems no matter what, if you ask for AAC audio, the "backend" crashes (I tried mencoder & avisynth for the source).

Theora+vorbis in mkv doesn't work out of the box either, the file isn't playable in mplayer (and I'm too lazy to try further :p)

[tetsuo55]

Hi, i recently found your program and use it to convert RMVB files to XVID-AVI files.

however some of the files will hang on converting, fps will drop to 0.1 and it will hang forever, Mencoder will be using 100% cpu

what info do you need to fix these issues?

[ReinerSchweinlin]

Nice App :)
I tried to convert some old files to xvid/nero aac in MP4 container. Since Audio was horribly low, I tried "normalize", but since it´s mplayers/mencoders one-pass volume-adaption, it "pumps" all the time.
So I tried ssrc, which should do a 2-pass normalize. I can´t get it to work, though. It says "beta".
Has anyone gotten shibatch to work in Mediacoder?

[robert88]

will be added an extra option for font size?

[DarkZell666]

I think the author isn't investing into this thread anymore, your best bet would be his own website. Any info here is kinda out of date <_<

Main site : http://mediacoder.sourceforge.net/
Forum : http://forum.mediacoderhq.com/ (link from main site top menu anyway)

[robert88]

thx, but there people ask the same thing on his forum, and they don`t get a proper answer.

[Neillithan]

I would have to say that this is by far the most useful program I've used for encoding h264 or transmuxing files. This program needs more love! :)

[Nozomi]

I've to agree with that, this program definitely deserve more attention... it is amazing, I've manage to convert a 1 hr RMVB file:

Video
Format : RealVideo 4
Codec ID : RV40
Codec ID/Info : Based on AVC (H.264), Real Player 9
Duration : 1h 8mn
Bit rate : 538 Kbps
Width : 640 pixels

to a PSP MP4 file:

within 1 hour and the outcome is perfectly ok with no sound track out of sync problem.

[Slifer]

Fos some reason the subtitle files just wont work for me when i try to hardsub them...

They show up in the preview but not in the outcome...

The subs are .ass (advanced sub station) type, and the video is .avi.

I am using vista but everything else works fine. Any ideas guys?

i tried again with Mediacoder the newest available to do a simple WMV (VFR)->MP4/MKV H.264 transcode useing AAC via Nero

The piping:

tream3708.264"


Matroska (it uses AVI as intermediate why ?) and MP4 it uses X264 with H.264 raw output as intermediate both frameworks lose frames @ the end (compared to the original) :(
so there seems only 1 logic explanation it looses the frames @ the piping and as x264.exe never loses frames (worked with the CLI for years never lost 1 frame) :D

i would say Stanley skip this piping framework finally and do it native (i guess then it finally would never lose frames and also all the sync issues people have would be gone if it's not a mencoder isue)

PS: I'm not quiet sure that fps=2997/100 is correct either for this source gonna check that maybe that's causing the frame lose

Stanley do you use a adapted version of X264 so that Mencoder and X264.exe syntax can be matched because

MP4:

# ".\codecs\x264.exe" - 1280x720 --fps 2997/100 --quiet --no-psnr --no-ssim --ke
yint 96 --min-keyint 25 --level 40 --me hex --merange 16 --no-dct-decimate scen

patial --crf 26 --sar 1:1 --threads 3 -o "C:\DOKUME~1\ADMINI~1\LOKALE~1\Temp\mcs
tream3708.264"

that is strange for X264 CLI syntax (though it encodes the original X264 CLI would stop with a error)

[devilsneck]

bug found..
when converting from flv, the audio of output goes out of sync with video.
also it cannot convert small files..
it could not convert a 1541kb file but could encode a 2216kb file.

anyway, its the best multi-video converter out there.
final soution to all your video needs....:D

The original x264's piping does not work well under win32. To avoid such problems it is better to use native win32 API instead of crt functions to implement I/O under windows.
