.bat's with FFMpeg

[linkRed]

Heythere.
I got plenty of episodes of a show, with english and russian audio tracks. Now, the thing is, russian audiotracks are separately from containers with the video and english tracks, are lying in the folder, when I need them to be inside the containers, with the video and english track. Tracks are named after containers, they got the same names, just the extension is different.
(like 1.mkv, 1.mp3, 2.mkv, 2.mp3...)
I need to write a .bat file that would join the files with the same name into new container, using FFMpeg. When I write...

FOR %%i IN (*.mkv) DO (
ffmpeg -i %%i -i "%%~ni".mp3 -acodec copy -vcodec copy "%%~ni"1.mkv )

It does join all equally named video and .mp3's files with the same name into new container(adding "1" to it's name), but only if initial container doesn't have the audio track inside of it. If it does, then it simply muxing the audio and the video from original container, and won't add another track.

Any1, help with the code please.

you can either

a.
try to understand the channel -map command (which i don't) or do a two step process:

b.
1. dump video (ignore audio) to temporary file (use -an to ignore all? audio tracks)
2. merge them like you do now.

c.
use mkvmerge

Option a. won't work either, unfortunately, tried. Same thing - can copy anything inside the container, but nothing on what's outside. Or I just tried it wrong.
Option c. would b 2 long. As I sad, it's not a single file, think of it as if u had 100+files=)
Option b would take two operations to be done. Somehow I believe... there should b an easier way, with only one bat file.

mkvmerge is available from the command-line:

for %%a in (*.mkv) do mkvmerge.exe -o "%%~na1.mkv" --compression -1:none "%%a" --compression -1:none "%%~na.mp3"

For ffmpeg, search "newaudio".

Thankx for mkvmerge advie man! But I need to know about FF too.
I tried to use -newaudio but had no luck with that. I tried this

FOR %%i IN (*.mkv) DO (
ffmpeg -i %%i -i "%%~ni".mp3 -vcodec copy -acodec copy "%%~ni"1.mkv -newaudio )

and this

FOR %%i IN (*.mkv) DO (
ffmpeg -i %%i -vcodec copy -acodec copy -i "%%~ni".mp3 "%%~ni"1.mkv -acodec copy -newaudio )

and that

FOR %%i IN (*.mkv) DO (
ffmpeg -i "%%~ni".mp3 -i %%i -acodec copy -vcodec copy "%%~ni"1.mkv -map 0:0 -map 1:0 )

I tried also lots of other things this night, but 4 no luck. So would u please explain to me how that works with FFMpeg?

[sneaker_ger]

Had some problems there myself, stupid ffmpeg always breaking stuff or not working as documented/badly documented. Try:

for %%a in (*.mkv) do ffmpeg -i "%%a" -i "%%~na.mp3" -vcodec copy -acodec copy -map 0:0 -map 1:0 -map 0:1 "%%~na1.mkv"

Sir, you are awesome. And brilliant. Choose what you like more.
I also find out one interesting thing, that might be useful as well.
When your code is

for %%a in (*.avi) do (
ffmpeg -i "%%a" -i "%%~na.mp3" -vcodec copy -acodec copy -map 1:0 -map 0 "%%~na1.avi" )

You get an audio, video from container and additional audio file, and the first audio track will be the additional one.
While here

for %%a in (*.avi) do (
ffmpeg -i "%%a" -i "%%~na.mp3" -vcodec copy -acodec copy -map 0 -map 1:0 "%%~na1.avi" )

the main track from the container will be the first one in queue.

Yet I didn't find a way to mux another audiotrack to container when it already has two of them -_-

Well, then we'd have to add another map:

for %%a in (*.mkv) do ffmpeg -i "%%a" -i "%%~na.mp3" -vcodec copy -acodec copy -map 0:0 -map 1:0 -map 0:1 -map 0:2 "%%~na1.mkv"

right?

Na-ah...

[matroska @ 0000000001EFDE90] Can't write packet with unknown timestamp
av_interleaved_write_frame(): Invalid argument

and with avi...

[avi @ 0000000001F36360] Application provided invalid, non monotonically increasing dts to muxer in stream 3: 1 >= 1
av_interleaved_write_frame(): Invalid argument

what dts?...

[sneaker_ger]

Decoding time stamp, which should be increasing (or at least not decreasing, though some programs require increasing), so that all frames are in the chronologically correct order.
Can't help you with that. ffmpeg can be a PITA, that's why I use mkvmerge whenever possible.

[linkRed]

Yeah, well then I'll have to learn the mkvmerge docs.
Thank you man. Problem solved. For now...

[smok3]

@sneaker_ger, yeah, but all that assumes that 1st track is video, which is not always the case, so -map is pretty problematic for scripting use, one way or another.
