Can't use avidemux_cli command line or batch

[isidroco]

I need to extract audio using this command (in windows):
c:\DVD\Avidemux\avidemux_cli.exe h:\VIDEOS\x.avi --save-raw-audio h:\VIDEOS\x.mp3
which (incorrectly) generates a 768 bytes file

Command works correctly if x.avi is located in Avidemux folder:
c:\DVD\Avidemux\avidemux_cli.exe x.avi --save-raw-audio x.mp3

Final messages of wrong run are:

Due to command line restrictions, path I believe?
Think path and file needs to be quoted (string).

Code Select Expand

c:\DVD\Avidemux\avidemux_cli.exe "h:\VIDEOS\x.avi" --save-raw-audio "h:\VIDEOS\x.mp3"

[isidroco]

After some experiments, this works:
c:\DVD\Avidemux\avidemux_cli.exe --load x.avi --save-raw-audio h:\VIDEOS\16_VIDEOS_USA_2016\w\x.mp3

this doesn't:
c:\DVD\Avidemux\avidemux_cli.exe --load c:\DVD\Aviemux\x.avi --save-raw-audio h:\VIDEOS\16_VIDEOS_USA_2016\w\x.mp3

* Quotes are only necessary if spaces are present on path/filename and in my example gives same result adding them or not.
* Please notice that x.avi is placed on Avidemux directory, if path is specified it stops working even in same place as before.
Couldn't make it work outside avidemux dir.

this doesn't:
c:\DVD\Avidemux\avidemux_cli.exe --load c:\DVD\Aviemux\x.avi --save-raw-audio h:\VIDEOS\16_VIDEOS_USA_2016\w\x.mp3

If this was copy/paste then it can't work: typo

- command path should include path to avidemux exe's, can be called from anywhere within windows.
- probably more issues going on, like user (windows) restrictions where you can write or not on your system drive, ...

Jan, Thanks for your input. Unfortunately I misstyped here. Command when doesn't work generates a 768bytes empty mp3 instead of the correct +1mb file. It's not a permissions problem because file is generated, and I'm using win XP in a FAT32 partition with full access to all folders (FAT32 doesn't have permissions).
Will try in another win7 pc.

[Jan Gruuthuse]

OK try
- with GUI: replace avidemux_cli.exe with avidemux.exe perhaps more info will pop-up.
- in batch file place echo in front of instruction line perhaps something will show on command prompt?

echo c:\DVD\Avidemux\avidemux_cli.exe  --load x.avi --save-raw-audio x.mp3

fat32 has 2GB size limitation

[isidroco]

All my experiments are done out of batch. (Command line).
Can confirm that problem does NOT occur on win7 x32. Unfortunately I need this working on xp, 

System and avidemux drive is fat32, rest of units are ntfs. But as I said: imposible to be permission problem here.

Attached w7/xp log files from individual experiment, and my batch to extract audio from all videos on a folder which works on win7 and not on winxp due to avidemux bug.

PS: REM on line 111 must be removed

PS2: Annoyance, process is stopped to ask Y/N here (is there a way to skip and answer NO on these cases?):
* Question *
* This video contains B-frames, but presentation time stamps (PTS) are either missing or monotonically increasing. Avidemux can try to reconstruct correct PTS by decoding the entire video. This may take a lot of time. Proceed? *

Yes or No (Y/y or N/n) :

Is this now because you're using the avidmux.exe GUI? Was only meant for for testing. Switch back to avidemux_cli.exe.

Otherwise redirection from a file. Like a reply: Yes or No or Enter

- 32-bit is (maybe) no longer supported
- XP is EOL and no longer supported

[eumagga0x2a]

At the first glance, the problem seems to be located in the AVI (OpenDml) demuxer.

32 bit is supported, Windows XP is not (cannot even test), but Mean might have a VM somewhere and, more importantly, knowledge of its quirks and limitations. A sample would be nice anyway.

[eumagga0x2a]

Maybe it is related to https://github.com/mean00/avidemux2/blob/master/avidemux_plugins/ADM_demuxers/OpenDml/ADM_odml_audio.cpp#L117 ("r" vs "rb" mode for fopen), maybe not. Difficult to tell with nothing but a smartphone.
