Help: ffmpeg .bat .ogm -> .mp4

[doomtomb]

Hello,

I have a lot of Anime in the old .ogm format (I think because it was the first dual audio stream container? correct me if I'm wrong). I am trying to batch convert this to .mp4 except I have no experience writing command line ffmpeg.

• Copy the video
• Convert both audio streams from .ogg to .aac
• Copy the subtitles

Thank you in advance for any help.



What I've tried already:

for %%a in ("*.ogm") do ffmpeg -i "%%a" -vcodec copy -acodec copy "newfiles\%%~na.mp4"
pause

This just copies video and only 1 audio stream and doesn't copy subtitles.

You must use the map option, see https://trac.ffmpeg.org/wiki/How%20to%20use%20-map%20option for some examples.

Ok, so that's getting me on the right track... but now I'm left with something like this and getting errors regarding invalid filename syntax:

for %%a in ("*.ogm") do ffmpeg -i "%%a" \
-map 0:0 -map 0:1 -map 0:2 -map 0:3 \
-c:v copy \
-c:a:0 libfaac -b:a:0 96k \
-c:a:1 libfaac -b:a:1 96k \
-c:s copy \
"newfiles\%%~na.mp4"
pause

[Baldrick]

Post the error output

and don't use any \ or new line.

for %%a in ("*.ogm") do ffmpeg -i "%%a" -map 0:0 -map 0:1 -map 0:2 -map 0:3 -c:v copy -c:a:0 libfaac -b:a:0 96k -c:a:1 libfaac -b:a:1 96k -c:s copy "newfiles\%%~na.mp4"
pause

It's not exactly easy or pretty

I did as you asked and now I get 1 error:
Unknown encoder 'libfaac'


I follow the tutorial https://forum.videohelp.com/threads/356314-How-to-batch-convert-multiplex-any-files-with-ffmpeg so all I have is ffmpeg.exe and the bat file and the videos.

[Baldrick]

Remove the line breaks and \.

for %%a in ("*.ogm") do ffmpeg -i "%%a" -map 0:0 -map 0:1 -map 0:2 -map 0:3 -c:v copy -c:a:0 libfaac -b:a:0 96k -c:a:1 libfaac -b:a:1 96k -c:s copy "newfiles\%%~na.mp4"
pause

[Baldrick]

Try with libvo_aacenc instead of libfaac

[doomtomb]

Thanks, but still two errors remaining... it all has to do with the filename writing

Could not write header for output file #0 (incorrect codec parameters ?): Error
number -22 occurred

And

    Stream #0:3(English): Subtitle: text
[mp4 @ 02617820] Could not find tag for codec text in stream #3, codec not curre
ntly supported in container

^ I think I need to convert the subtitles?

[Baldrick]

Try without any any batch first. Just one file. And see if you get any errors.

And the subtitle stream copy might not work in a mp4 container.

[doomtomb]

It's working away perfectly now.

my final code is:

for %%a in ("*.ogm") do ffmpeg -i "%%a" -map 0:0 -map 0:1 -map 0:2 -map 0:3 -c:v copy -c:a:0 libvo_aacenc -b:a:0 96k -c:a:1 libvo_aacenc -b:a:1 96k -c:s mov_text "newfiles\%%~na.mp4"
pause

I just had to specify:

-c:s mov_text

for conversion to mov_text from regular txt, a supported mp4 stream.




Thank you so much.

[Baldrick]

Great!
