New tool: MVPRecode

I would like to see your batch file to get some tips as i am not well up on writing them.

The reason for asking about the transcoding on the fly was i would like to try mencoder instead of ffmpeg, i think this is what you are saying is possible?

Many thanks Jase

yep...any encoder you'd like...but i finally figured out ffmpeg's switches and seems to get better quality for me..[with a few changes to opts]
almost finished with the que'ing plugin and will post probably tonite..
i include several encoding example commands but it's totally editable so anything's possible..

Hmmm, do you get this message after it has been transcoding (do you see a frames / percent counter at all)?

Hi, I tried the debug version but get the same result.

Mencoder doesn't start.

EDIT: I've just tried copy and pasting the command line that is built and it seems to have a number of errors in it?

acodec=mp2:abitrate=192-priority belownormal (needs a space after the audio bitrate 192)
-vf scale=352:199, expand=352:288 (the space is erroneous after the "352,199," and causes incorrect parsing of the command)

Okay, I'll have a quick look and see what's going on....

Could you post the MVPRecoded.XML file you are using?

If I find anything, I'll post an updated version asap.

[djtaylor]

The xml file is the default. I didn't realise that you were getting the settings from there, I tried this very quickly without looking.

The lack of space before the -priority can easily be fixed by inserting on in the xml string but I can't fix the extra space after the scale command because there isn't on there in the xml file so that'll have to be taken out programmatically.

Great tool, I didn't really appreciate how useful this will be until I tried it.

So just to clarify, adding a space at the end of the <encoding default> line after the 192 fixes that one but it needs recoding to sort the extra concatenation space that is being put in by code after the scale=[width]:[height] one:-

Code:

<VideoFilter>-vf</VideoFilter>
<VF_Scale>scale=[width]:[height]</VF_Scale>
<VF_Expand>,expand=[MVP_Width]:[MVP_Height],</VF_Expand>

Okay,

It looks like I found the error (for the scale and expand thing anyway)....

I have looked but I haven't been able to find the "priority" thingy... Could you try with this version (and the XML that comes with it) to see if it works correctly now??

If it doesn't, I really want to nail that priority space thingy.... (I checked in my code but it says: command_line += " " + <priority setting>!!

Glad you like it!! It's saved me a lot of work (and finally gets my movies in the correct aspect-ratio on the TV!).

[djtaylor]

Did you send the right one? I see that one as vresion 0.1 which hasn't fixed anything.

David.

[Ton]

Okay, here's the real fixed version (0.2).... Look's like I made a little slip when creating the zip-archive ;-)

Also found out why I hadn't run across it.... Looks like C# uses the computers national settings for converting strings to double values, and that's why it treated my "1.4" as "14"!!! I have now fixed my computer (for now), but I'll look into another convert function....

If this doesn't work, I'll build a version that dumps a whole lot of text to the screen, so we can see what's actually going on....

Again, like I said, I have been able to verify and fix the additional space before the "expand" filter, but haven't found anything on the space at the priotity command...

This is a great little conversion program and great idea. Is there any chance of having it chain multiple VOB files when you give it the first VOB in a set?

[Ton]

Hmmm, it already does that (in a number of cicrumstances) when:

1. All the VOB's (together with the IFO's) are in one dirctory; just give it the name of (either to top-level or the VIDEO_TS) directory and it'll treat the dir as a DVD (just plain standard mencoder stuff)...

2. If a file name ends with a number (before the extension), it'll add one to the number and see if that file exists... If it does, it'll instruct mencoder to play all the files with the same number scheme, but it'll still produce one result file (concatenating all the seperate files). It'll do the same with subtitle-files (if present)...
