Re: [FFmpeg-user] ffmpeg overlay last frame remaining in video
Thank you. I'm learning. What I set up for all the various parameters was what I pieced together while trying to figure out how to create the overlays, both through trial and error, reading the documentation on ffmpeg.org, and asking experts for guidance. This particular ffmpeg is being used in an Android app I've developed. It's very painful to compile ffmpeg via android ndk constantly and then have to rebuild the apk and push out to the google play store. ... for your main issue, your overlay needs the eof_action option: overlay=eof_action=pass Worked like a charm. Thank you! What is this -itsoffset for? Users can set when they want to start the overlay video Why use -c:v libx264 *and* -vcodec mpeg4? These are mutually exclusive, and mpeg4 is chosen as the encoder since it was declared later. I have corrected this. Your main input is 3/1001. Why are you setting the output frame rate with -r 30? I have removed this. Why do you use single pass with -b:v instead of -crf? See: https://trac.ffmpeg.org/wiki/Encode/H.264 Interesting.

Assuming you can get the scene detection filter to print you the frame
numbers, and they turn out to be (e.g.) 0 22 134 157 222 331 413, you
can do this shell magic (line broken with '\' for readability):
FRAMESPEC=; \
for f in 0 22 134 157 222 331 413; do \
if [ $FRAMESPEC = ]; then FRAMESPEC=eq(n\,${f}); else
FRAMESPEC=${FRAMESPEC}+eq(n\,${f}); fi; \
done; \
ffmpeg -i video.mkv -vf select=$FRAMESPEC -vsync 0 video.%04d.jpg
(The if term is a bit crude and can be improved by some ${?bla}
construct. I didn't bother.)
In other words: Give the select filter an expression which evaluates to
!= 0 on the correct frames (frame number 'n'). That's a logical OR
expression, achieved in ffmpeg by adding the eq() expression terms.
The -vsync was added so that the image2 muxer doesn't blow the
resulting stream back up to 25 fps, but only passes through the frames
from the filter one by one.
(The %04d does _not_ represent 'n', as the muxer has no knowledge of
that - it just counts upward. You shouldn't mind.)
I verified this with a video where each frame was overlayed with its
number (drawtext filter with text=%{n}), and by selecting those
frames with my script and checking whether the correct ones were
extracted.
Try that,
Moritz
P.S.: The whole thing will break once the Unix command line or the
amount of command line bytes to be evaluated by ffmpeg get too long.
;-)

[FFmpeg-user] Mulitple output files from one -map?
Hi, Here's my ffmpeg command: ffmpeg -i input1.mkv -i input2.mkv -filter_complex myfilter[output1][output2] -map [output1] -f null /dev/null -map [output2] -y high.mp4 medium.mp4 low.mp4 myfilter is a custom filter that uses dualinput and gives two outputs. high.mp4 is encoded correctly with the contents of output2, but medium.mp4 and low.mp4 are copies of input1.mkv. Is there a way to encode multiple copies of output2 using -map? Specifying -map [output2] more than once causes errors saying it's already been used. Inserting a split=3 filter into the filter chain works fine and allows each output to be mapped individually: ffmpeg -i input1.mkv -i input2.mkv -filter_complex myfilter[output1][output2];[output2]split=3[one][two][three] -map [output1] -f null /dev/null -map [one] high.mp4 -map [two] medium.mp4 -map [three] low.mp4 Is that the best way to do this or can -map be used somehow? Would the split filter potentially be doing extra frame copies unnecessarily? I'm using current ffmpeg head.
