Error applying audio codec

[Varro]

Hi! I have files like:

Code Select Expand

=====================================================
Video
=====================================================
Codec 4CC: H264
Image Size: 640 x 480
Aspect Ratio: 1:1 (1:1)

Codec: PCM

Bitrate: 192000 Bps / 1536 kbps

I want to convert them into files with video x264 with 2048 bitrate and audio MP3 192 with following batch file:

Code Select Expand

set avidemux="c:\Program Files\Avidemux 2.7 - 64 bits\avidemux.exe"
set videocodec=x264
set videobitrate=cbr=2048
set audiocodec=MP3
set audiobitrate=192
set outputformat=MP4
for %%f in (*.MOV) do %avidemux% --video-codec %videocodec% --video-conf %videobitrate% --audio-codec %audiocodec% --audio-bitrate %audiobitrate% --output-format %outputformat% --force-alt-h264 --load "%%f" --save "%%f.mp4" --quit

But:
1) when GUI is shown audio settings didn't load (they set to "Copy").
2) when converting i got error "Unsupported. Only AAC, AC3, E-AC3 and mpegaudio supported for audio"

How can i fix this problem?

Try with this

Code Select Expand

set audiocodec=Lame

If still refused try using MKV muxer

set audiocodec=Lame

I've tried MP3, AAC instead of "Lame" - with same result. I think main problem is that audio codec settings doesn't apply to GUI and conversion process. With manual setting via GUI i can convert this file successfully.

With MKV muxer - problem is that audio settings doesn't apply to output - it just copy.

[eumagga0x2a]

--load should come first.

[Varro]

--load should come first.

Same result. Order doesn't matter.

I write again - audio settings don't apply from command line to GUI and (as I think) to convert process.

[eumagga0x2a]

What version are you using?

Edit: nevermind, it is 2.7, probably 2.7.0 for win64.

[eumagga0x2a]

The order matters exactly as I said. With the current version (for me it is the current git master, for you the latest win64 nightly if you don't build from source), I get exactly the same error if I don't put --load option with the source video file name including the path before any audio options. It works if the video is loaded first.

[eumagga0x2a]

Could you please post the output of MediaInfo for the source file? Maybe there are more audio tracks, and the command line converts only the first one.

[Varro]

Yes, version is 2.7 x64 downloaded yesterday from fosshub.

The order matters exactly as I said. With the current version (for me it is the current git master, for you the latest win64 nightly if you don't build from source), I get exactly the same error if I don't put --load option with the source video file name including the path before any audio options. It works if the video is loaded first.

I use modified example from wiki where "load" is after all codecs
Anyway with following config

Code Select Expand

set avidemux="c:\Program Files\Avidemux 2.7 - 64 bits\avidemux.exe"
set videocodec=x264
set videobitrate=cbr=2048
set audiocodec=MP3
set audiobitrate=192
set outputformat=MP4
for %%f in (*.MOV) do %avidemux% --load "%%f" --video-codec %videocodec% --video-conf %videobitrate% --audio-codec %audiocodec% --audio-bitrate %audiobitrate% --output-format %outputformat% --force-alt-h264 --save "%%f.mp4" --quit
I get same error "Unsupported. Only AAC, AC3, E-AC3 and mpegaudio supported for audio".

Could you please post the output of MediaInfo for the source file? Maybe there are more audio tracks, and the command line converts only the first one.

Well, there is no second audio track... Could you please try the latest nightly then?

If you want the audio track to be encoded as MP3, use Lame as --audio-codec

[Varro]

Build 171127 - much better. Output in GUI is set to MP3 (lame). But now i can't change audio bitrate - for any value audio bitrate remains 128 (i've set codec to lame).

Updated
Also I found following in log:

Code Select Expand

[audioCodecSetByName] 16:59:25-814 Audio codec Lame set for track 0 (index=7)

Unknown command :--audio-bitrate

Found garbage 192

[eumagga0x2a]

Looking into it.

[eumagga0x2a]

The --audio-bitrate option has been removed by this commit in March 2012. The Wiki is terribly outdated. Please use a project script (.py) to supply codec options, just don't forget always to load the video first.

Edit:

Code Select Expand

adm = Avidemux()
adm.audioCodec(0, "Lame", "bitrate=192", "preset=0", "quality=2", "disableBitReservoir=False");

[eumagga0x2a]

The --video-conf option has gone too, as well as the --force-alt-h264 one. You should configure (with a video loaded) video and audio codecs and the output container to your liking in Avidemux, then save this as a project script, edit the resulting .py file deleting the lines starting with

Code Select Expand

adm.loadVideo
adm.clearSegments
adm.addSegment
adm.markerA
adm.markerB

and load the video on command line followed by --run "path/to/your/script.py". The batch would look like the following:

Code Select Expand

set avidemux="c:\Program Files\Avidemux 2.7 - 64 bits\avidemux.exe"
set project="path\to\edited\script.py"

for %%f in (*.MOV) do %avidemux% --load "%%f" --run %project% --save "%%f.mp4" --quit

[Varro]

Great, thank you for help and useful app!
Using previously saved project is much more convenient than specifing all in command line.
