I figured out at one point that if my command line was more than about 900
characters long, ffmpeg wouldn't handle it.
I was doing a filter_complex concat operation. My solution was to recognize
the extra long command line and switch to creating a temporary file with
the list of input files, and s

I run ffmpeg from a program I wrote that sets up the input file names to
easily convert individual images to a video. Is the swscaler warning
message because of my output format (yuv420p) or a format in the source
photos from my GoPro?

I use drawtext when I create videos from time lapse photos using this
command:
ffmpeg.exe -hide_banner -r 30 -i
C:\Users\Wim\Videos\20221009-PSSC\Wim%05d.JPG -vf
crop=in_w:9/16*in_w,drawtext=fontf
In my experience, adding a -map 0 option makes copying all the extra stuff
more likely. This was my command to compress a DVD I'd ripped to an MKV
file, converting the video to h.264 but copying all of the other tracks and
details.

I'm using ffmpeg to concatenate a large number of files from my dash cam
and then speed things up by a factor of 60.
It works properly when the number of files is small, but fails as the
filter_complex option string expands. I'm generating the command line from
a program.
From the ffmpeg generate
I've encountered the error message "Too many packets buffered for output
stream 0:1." when converting files and would appreciate direction in how I
might get around the error.
When it occurs, there is a zero length output file created and FFMPEG exits
with an error result.

I don't have an nvidia GPU, so can't see what it looks like, but what do

I use setpts to speed up some video that I'm concatenating from my car's
dashcam. The process is consistent and hasn't changed recently. Here's an
example command line:
C:\Windows\ffmpeg.exe -hide_banner -i
D:\ROAV\MOVIE\2024_0803_173613_229.MP4 -i
