This is common for programs that usually/often send their work-product to 
stdout; the status messages have to go somewhere and that's stderr*. It does 
help to look at the exit status to see if there's really an error (exit 
status = 0 usually means success, even if there was output on stderr).


*ffmpeg does have options to turn off a log of the logging, but there's 
really no need to do that if they can be ignored.




The python wrapper was interpreting this as an error.

A wrapper written by someone who hasn't experienced that above :).


When scripting things like ffmpeg, I find it helpful to merge stderr and 
stdout into one channel ("2>&1") but look first at the exit status.

Yup, doing a subprocess call rather than a wrapper has always worked better
for me.

Best,

Thank you for this suggestion. The issue was that ffmpeg was sending the
above logs, which don't correspond to any error to STDERR. The python
wrapper was interpreting this as an error. I changed the python wrapper
based code to one where I invoke ffmpeg directly as a command. This removed
the error :D

The problem is that there isn't an error message in the original post.


This happens only on the production machine and not on my local machine.
What's different between the two?  Try working out the exact ffmpeg command 
and run it from the command line, if that succeeds then there may be an 
issue with the python; if running from the command line fails, post the 
complete command and complete output here. Are you getting anything on 
stderr (and what is it)?


In general, I mistrust wrapper libraries for things like this- I'd rather 
create the full command string myself and execute that; it gives much better 
control over the process.

Re: [FFmpeg-user] Unable to understand error

2022-03-04 Thread Rukmangadh Sai Myana 
Hi,
Pardon me. I am using the ffmpeg-python
 package inside my code. The
exact code that is giving me error is as follows:

input_clip = ffmpeg.input(
> os.path.join(animation_dir, 'input_clip.h265'))
> animated_text_clip = ffmpeg.input(os.path.join(
> animation_dir, f'animated_text_clip.h265'
> ))
> clip_stream = ffmpeg.filter(
> [input_clip, animated_text_clip],
> 'overlay', y=int(0.8 * video_height),
> format='auto', shortest=True
> )
> out = clip_stream.output(
> os.path.join(tmpdir, f'clips/clip{idx}.h265'),
> vcodec='libx265'
> )
> out.run(overwrite_output=True,
> capture_stdout=True, capture_stderr=True)
>

I am essentially trying to overlay one video over another. The issue is
that the python package throws the error that I shared above and exits.
This happens only on the production machine and not on my local machine.
So, I am quite puzzled as to what this error corresponds to. Thanks in
advance for your help.

hi Rukmangadh
When you post for help you should send the command that gave you the error
otherwise how can we solve?
which part of India are you from?
