I ran a single test with it, and the TTML formatting looked good, but I still

As usual you add additional premise that does not makes sense and is
incorrect.

rgb24 is not planar but packed.

gbrp is used internally and works as expected, as filter does not care
about R/G/B/A order.
It just shuffles planes.


thanks, that explains the unexpected result. It would be helpful to add 
a note to the documentation:
"The input pixel format must be planar, for example gbrp. If a 
non-planar pixel format is used (for example rgb24), a format conversion 
is inserted automatically and you might get unexpected results."

[FFmpeg-user] How to extract audio from video without re-encoding?

2021-10-11 Thread inhahe 
I want to extract audio from any arbitrary video file and have it save to
an audio file without re-encoding and without me knowing ahead of time
which audio file format to use.

I don't know how to do it because ffmpeg requires an output filename with
an extension, which means I have to specify the audio file format within
the command. I want ffmpeg to choose the audio file format for me based on
the type of audio embedded in the video, much like the -x parameter does in
youtube-dl.

How can I do this? Thanks.

Hi,

Thanks for your help.

I have gone through that online translators.

I am looking for the FFmpeg command which can simplify my requirement.

You can suggest any other linux tool/applications for this.

Thank you.

You might try this

https://gotranscript.com/subtitle-converter

If you're comfortable with coding at all, you can create a relatively 
sophisticated converter that accounts for options like positioning and styling 
in ttml but which are largely foreign to srt.
