Hi,
0n 06/10/[EMAIL PROTECTED]:52 Paul Bawon told me:
I'm currently working on a project whereby I need to create a video
file from an mp3 audio track and one jpg image. I've been researching
Transcode to see whether this is possible (as well as ffmpeg), and
have attempted a few Demuxing techniques, but to no avail.
Which output format or media do you need?
I need it in a .mpg (MPEG2) with a mp3 audio layer.
There are probably less expensive ways to get the result you want
without producing a video at all. Further something like dvd or
(sv)cd offers some features where you can mix sound with stil images.
Have a look at dvdslideshow, if in need.
Unfortunately it has to be played back by a portable media player
that only plays .mpg
In more general you can use transcodes imlist import module. Take a
look at the duration of the mp3 file lets say its 3 min long.
Further lets assume you want a 25 fps mpeg4 file. Scale the image to
the desired output size. Create a file image.list with 3x60x25 entrys
for that image.
transcode -i image.list -x imlist,mp3 -p Auido.mp3 -o film.avi \
-y ffmpeg -F mpeg4
Probalby you have to play with -k and/or use --use_rgb.
I have located the command via ffmpeg to achieve what I need. For
future reference it is:
ffmpeg -shortest \
-loop_input -f image2 -i some_image.jpg \
-i some_audio.mp3 \
-sameq some_result.avi
Then I use ffmpeg to convert the .avi to mpg.
Thanks for your help anyway.
Regards
Paul
