Hello,
Can ffmpeg put various mapped inputs into different Input streams in the same
container output file?
So far I only have created output container files, which only had "Input
#0":Input #0 Stream #0:0 Stream #0:1 Stream #0:2 etc.
Can I also add to this container another input, like:
Input #1 Stream #1:0 Stream #1:1 Stream #1:2 etc.
If yes, how can I go about with ffmpeg?
Thank you.-SR.
Hello, Stub Spamrefuse (curious email addresses you have there):
Yes, FFmpeg can put various mapped inputs into different _output_
streams in the same container output file.
Invoke FFmpeg with multiple '-i inputfile' arguments to read multiple
inputs. The '-map' option gives a flexible way of mapping input streams
into output streams, perhaps via filters. See "Stream selection" in the
documentation for a description:
<http://ffmpeg.org/ffmpeg-all.html#Stream-selection>.
I don't follow what you mean by "into different Input streams in the
same container output file". Streams in an output file are no longer
input streams, are they?
But FFmpeg is a complicated tool. It may be easier if you give a
specific example, with a specific command line and console output, and
tell us specifically what about that example is different than what you
want.
