WAVE_FORMAT_EXTENSIBLE is something that indicates an extension to the format chunk. It's used to indicate stuff like more than 16-bits in WAV, more than 2 chans, etc. I'm not expert on that, and I didn't test with more than 2 chans on my samples, but I'll see if it can be "fixed" or worked around in the script. If not, then you may need to stick to 2chans for now, or modify the batchfile and make it dump the audio to a real WAV file (with 6chans) and encode it to flac, bypassing the pipe thing

[microchip8]

Well, I just did a small test here, dumping the audio to a real WAV file (6chans) with mplayer and trying to encode it with flac. It still reports the same thing so I guess it's mplayer that doesn't add the WAVE_FORMAT_EXTENSIBLE to WAVs, regardless if one uses a pipe or physical file to encode from. All one can do is report this to mplayer-dev-eng mailing list and hope someone makes a patch

EDIT: I've reported this to the list, will wait and see what answers I'll get, if any

Here's a patch for that which fixes stuff (tested and works here). After my post on the mplayer ML, Jason picked it up and decided to hack something together.
How to patch:

1) download patch, extract and place it in the libao2 directory inside the mplayer's one
2) cd to libao2 and issue following cmd: patch -p0 < ao_pcm-waveformatextensible.diff
3) compile mplayer
4) .....
5) PROFIT!!! :p

^thanks, i'll test it out when i got some time (at work now).
fyi, for the time being i was using 6 channel ac3 sound which worked well.

Note that the patch was committed yesterday so the above is no longer needed, provided you pull latest mplayer from SVN

ChangeLog for version 1.5.3
* Small bugfix: wrong variable used when exporting from the send_email_func() function to the batchfile
* Added new variable DEFOUTPUT to the config where user can set a default output directory. This updates the config version to 13
* Updated the set_output_filename_func() function to support the above change
* Use one variable in the presets (divxparams) for all MEncoder lavc mpeg4 encoding options. Reduces some code and simplifies things a bit
* Updated the preset.cfg file to support the "one variable for all lavc mpeg4 encoder opts"
Note: those using custom preset files for encoding should read the preset.cfg file in the doc dir and
adapt their existing preset files to be compatible with the changes. Previous older custom presets written by users will not work with this and future versions of divxenc!

[microchip8]

ChangeLog for version 1.5.4
* Small bugfix: the $ildctme interlace variable wasn't passed on to mencoder
* Space escaped some previously missed variables

[microchip8]

ChangeLog for version 1.5.5
* Reworked a bit the audio channels decode/output function. This function also got renamed from
audio_channels_func() to audio_channels_decode_func()
* Added support for the audio channels filter which can be used to add/remove/route channels. This updates
the config file to version 14 and adds variable ALLOW_AUD_CHANNELS
* Some various small improvements

[microchip8]

ChangeLog for version 1.5.6

* Small bugfix in the get_devices_func() function; script exits when user hits enter to accept default device
* Updated the man page

[microchip8]

ChangeLog for version 1.5.7
* Bugfix for the ps3 preset: autoapsect -> autoaspect. Reported by Thomas Troeger

[microchip8]

ChangeLog for version 1.5.8
* Add -nosub to prevent auto-loading of subs

[microchip8]

ChangeLog for version 1.5.9
* Workaround mencoder stupidity. With recent versions of mencoder that have subs enabled by default
(who came up with that great idea?), in case the user selects to dump a sub for importing into mkv/mp4, during
multipass encoding the first sub will always get hardcoded due to missing -nosub option in the 2nd/3rd pass code.
This is only valid for multipass encodes so people using one pass modes (-1p or -fq) are safe.
* Small update to the -scan option. Just check if input file is there, regardless if user provides the full path or not

[microchip8]

ChangeLog for version 1.6.0
* Added support for setting subtitle codepage during hardcoding of external subs
* Added support for the audio equalizer filter. This updates the config file version to 15
* Removed 'time' requirement
* Fixed a bug: removed a double semicolon in the hq preset which causes mencoder to exit

[contador]

Thanks Froggy :)

[microchip8]

ChangeLog for version 1.6.1
* Remove double $HOME variable in the -scan option

Hi, it's look like great app :) But I can't convert my video, it is blu-ray .m2ts file, failing when trying to calculate bit rate for 700 mb output file (with me gui option 0). I guess, if set custom bit rate will work, but I want exactly 700 mb :D.

P. S. Would be great if there was an option that offers different resolution for output file :p

Thanks for the script!

P.S. 2 I forgot to put the error output

Which formula to use? [default is 0]:

-> Detecting video length...

Using Ubuntu 10.04 but mplayer is from another repo (because of VDPAU) I compile mplayer from svn without installing and set paths to mplayer and mencoder in dixenc's config, but error still here.

Sorry, m2ts/ts could be problematic in both divxenc and mencoder.

Eh? Scaling is very much supported by the script

Thanks for the script!

Using Ubuntu 10.04 but mplayer is from another repo (because of VDPAU) I compile mplayer from svn without installing and set paths to mplayer and mencoder in dixenc's config, but error still here.

Can you provide a small sample from that file?

[tolostoi]

Eh? Scaling is very much supported by the script

Yeah, but I'm nooby :confused: and somthing like
640x480
720x400
... or whatever. I mean to offer a resolutions that match on aspect ratio, because for me is hard to calculate and divide / 16.
I know, with this info
-> Detecting FPS value...
-> Detected 25.000 FPS
-> Number of frames: 132762

Would you like to set/force the Output Frame Rate (FPS)? [y/N]:
Would you like to do Frame Rate Conversion? [y/N]:

-> Detecting cropped resolution...
-> Cropped resolution is: 720x560

-> Detected Aspect Ratio (AR): 1.7778:1
-> Storage Aspect Ratio (SAR): 1.2857:1
-> Pixel Aspect Ratio (PAR): 1.3827:1
-> Total pixels: 403200

can calculate the resolution, but is hard for me. If it can be set the width manualy and the script offer rest will be good.

Can you provide a small sample from that file?I don't know how to cut piece, can cut a part with avidemux, but output wil be another container.
Edit: I found how to cut a piece (with tsmuxer) I wil sent link on PM

[microchip8]

@tolostoi

Sorry, I don't think I'll add this for the resolution. But you can already let mencoder do it for you as the 'scale' filter supports it. From the man page of mplayer...

0: scaled d_width/d_height
-1: original width/height
-2: Calculate w/h using the other dimension and the prescaled aspect ratio.
-3: Calculate w/h using the other dimension and the original aspect ratio.
-(n+8): Like -n above, but rounding the dimension to the closest multiple of 16.

So, for example if you want to scale the width to 720 and let the height be auto-calculated and be divisible by 16, you can provide to divxenc 720:-10. It will calculate the height taking into account the prescaled aspect ratio (which is the -2 from above) and if you add 8 to it (the -n+8, thus resulting in -10) it will give you a height divisible by 16. Note that if you use that in divxenc, you'll get errors in some of the informative functions that print stuff but you can safely ignore that. They're not critical, just print information

About the target file size calculation. I did a few testings here and it seems the default TS demuxer of mplayer does not report correctly the length (ID_LENGTH appears to always be 0.00). So I can fix that by switching over to -demuxer lavf

hi froggy, i get a a segfault with xvidenc-8.8.4 on both fedora-18 and xbmcbuntu-12.1
if i take out this parameter it runs fine:
-vc mpeg12mite be an upstream change from mencoder ?

regards,

[microchip8]

Hi mousemurder,

Yeah this is possible. I think I'll remove -vc mpeg12 from future versions as MPlayer heads to ffmpeg's native implementation for mpeg decoding. The reason I used -vc mpeg12 in the past is because it produced less errors

EDIT: I'll release a new version without it tomorrow
