I am trying to use qaac for audio conversion and using ffmpeg to mux it back,
But I get an error with the piping line.Code:for %%a in ("C:\converts\*.*") do ffmpeg -i "%%a" -vf "scale=1280:trunc(ow/a/2)*2:flags=lanczos" -c:v libx264 -profile:v high -preset slow -tune film -crf 20 -an "C:\newconverts\%%~na.m4v" for %%a in ("C:\converts\*.*") do ffmpeg -i "%%a" -f wav -acodec pcm_f32le - | qaac --cvbr 256 --ignorelength --rate 48000 --native-resampler=bats,127 --threading -o "C:\newconverts\%%~na.m4a" for %%a in ("C:\newconverts\*.*") do ffmpeg -i "%%~na.m4v" -i "%%~na.m4a" -c:v copy -c:a copy "C:\newconverts\%%~na.mp4" pause DEL "C:\newconverts\*.m4v" DEL "C:\newconverts\*.m4a"
I have attached the screenshot.Code:for %%a in ("C:\converts\*.*") do ffmpeg -i "%%a" -f wav -acodec pcm_f32le - | qaac --cvbr 256 --ignorelength --rate 48000 --native-resampler=bats,127 --threading -o "C:\newconverts\%%~na.m4a"

Have you tried it without the batch? Same error?
But I have never tried ffmpeg with piping....so I have no idea....You could also try ask in https://ffmpeg.zeranoe.com/forum/index.php -

Now I am getting an error "Invalid argument" for m4v while muxing
Code:ffmpeg -i "*.m4v" -i "*.m4a" -c:v copy -c:a copy "C:\newconverts\%%~na.mp4"

ffmpeg cannot use wild cards like "*"
Before in the batch it was Windows dos that used the wildcard "*"
You need to format it in the same manner with a FOR statement such as the previous batch. Usually you would use a named TEMP file in a TEMP directory for the intermediate files, then DEL the temp files in the batch command -

Maybe, you should use mine

@Baldrick
My apologies, can't say how embarrassed I am for having not replied to your very old reply.
And, I am sorry.
I used this command in a batch file for bulk conversion:
for %%F in (*.MP4) do "C:\7z\ffmpeg-20130813-git-bbbd959-win32-static\bin\ffmpeg.exe" -i "%%F" -vcodec copy -acodec copy "%%~dF%%~pF%%~nF.mkv"
pause
while substituting (*.mp4) with (*.avi) and (*.flv) in each successive line of the batch file.
The pause command helped me to know that "all went fine".
Thanks. -
Well, I did not get the qaac and muxing thingy work. But I came at a workaround.
I have downloaded ffmpeg from http://oss.netfarm.it/mplayer-win32.php and downloaded the libfdk_aac.dll which was linked there. (Both 64 bit versions)
Now I am able to get a good quality aac file with ffmpeg and do not have to worry about the pipiing et al...
(P.S. If anyone able to get them working please share though )
My batch for running crf and 2-pass encodes goes here... I have added a small piece of code in resizing, which I came across in www. It will resize only if the files are having width lesser than "1280".
crf
Code:for %%a in ("C:\converts\*.*") do ffmpeg -i "%%a" -vf "scale=min(1280\,iw):trunc(ow/a/2)*2:flags=spline" -c:v libx264 -profile:v high444 -preset slow -tune film -crf 20 -ac 2 -ar 48000 -c:a libfdk_aac -vbr 5 -afterburner 1 "C:\newconverts\%%~na.mp4" pause

I have a m4v with multiple audio tracks and multiple subtitle tracks. The following only copies the default audio and no subtitles. How do I change it to add more?
Code:for %%a in ("*.14v") do ffmpeg -i "%%a" -vcodec copy -acodec copy "newfiles\%%~na.mkv"
-
After some digging around I changed it to
Code:ffmpeg -i "file.m4v" -map 0 -c copy file1.mkv
Conversion failed!" -
Mkv doesn't support data tracks. Add -dn to disable them.
Can you post the full uncut console output just to be sure? Ffmpeg is usually more specific than "error 40"
P.s your map 0 solution generally works as long as the chosen container supports all the streams you're adding. -

It throws up this error [matroska @ 01fcb6a0] Subtitle codec 94213 is not supported.
It looks like your last subtitle stream is a different format to the others?
On a side note, did you intend to have three video streams with different codecs and pixel formats? -
Sounds like your ultimate goal is stream mapping? You can do that within ffmpeg.https://trac.ffmpeg.org/wiki/How%20to%20use%20-map%20option https://trac.ffmpeg.org/wiki/How%20to%20use%20-map%20option

Ok so I will use -sn to copy the files using mapping without subtitles, then extract the subtitles to srt and finally mux together again. Thanks.

Hello,
I have used helpful suggestions from this thread. But, I am facing a new problem.
I have a collection of VCDs -- 47 in all -- which have been played again and again over a period of past 4 years. Now all VCDs have scratches and five of them play with some 'kitchir-kitchir' audio when video shows distortion (blocks) scattered over the entire display.
I don't mind any of it as the rest of content is played without any error.
But, I certainly don't want to sacrifice my collection.
Thanks to @baldrick, I used his suggested tool VCDgear and recorded/ripped VCDs in 47 subfolders. Everything went fine except some error correction in 5 disks.
My knowledge of FFMpeg:
In the past, I used this command in a batch file to convert multiple MP4 files to MKV in the folder:
for %%F in (*.MP4) do "C:\7z\ffmpeg-20130813-git-bbbd959-win32-static\bin\ffmpeg.exe" -i "%%F" -vcodec copy -acodec copy "%%~dF%%~pF%%~nF.mkv"
pause
As I understand it, the above command simply changes the container and does not recode.
This is the end of my knowledge of ffmpeg.
Here is what I want to do - without much loss to audio/video quality (I know recoding means some loss):
1. Convert MPG to some format which can be played on any CD/VCD player (failing which on any computer at least).
2. Convert MP2 Stereo audio to MP3 at 192KB and lower volume by -9dB -- with slight bass-cut, if possible.
This is what I have:
1. Latest FFMpeg in C:\ffmpeg-20151108-git-a5202bc-win32-static folder
2. MPG files = 94 -- 2 in each of the 47 subfolders.
[ Main folder is D:\MB and subfolders are D:\MB\Disk01 (01)… D:\MB\Disk01 (47) ]
I can do all that to a few files from what I have learned in this Forum; but, doing that to so many files will wear me down and will take me one year or so.
Hope I get some suggestion as has been the case in the past.
Please suggest anything about conversion too if what I want is not the right approach.
Thanks. -
