Dear Experts,
I'm trying to split an input file into 2 second chunks, transcode and assemble
using a concat muxer. And experiencing two problems:
major one:
1) when using ffmpeg -ss 00:00:08 -t 2 -i -c:v libx264
instead of seeking to second 8, ffmpeg seeks somewhere to second 15 or so.

No. But you should not be concatenating after transcoding in the first

Sorry for not producing the console output. I am a newbie in this forum.
The console output is given below.

I am using FFmpeg to convert a video file that has 5.1 surround sound for
playing it in a home theatre system. I used the following command.
ffmpeg -i "input1.mp4" -vf scale=720:-16 -c:v mpeg4 -vtag XVID -b:v 3000k
-c:a ac3 -b:a 448k "OUTPUT_FILE.avi"
I am able to play the video file on my

Hi,
I think this might have been a typo? in vf_colorkey.c:48 the "diff" isn't
normalized to 0 - 1, but to 0 - 3.
double diff = sqrt((dr * dr + dg * dg + db * db) / (255.0 * 255.0));
changing it to
double diff = sqrt((dr * dr + dg * dg + db * db) / (3 * 255.0 * 255.0));
seems to fix it for me.

Would you mind defining "known"?
Please find out what top-posting means and avoid it here.

This is a known bug. You'll just have to use it multiple times before you
get it to actually remove all the colors.

Hi,
I just found out that the colorhold filter doesn't behave as described.
In the documentation is written:
similarity
Similarity percentage with the above color. 0.01 matches only the exact
key color, while 1.0 matches everything.
But when I use similarity=1.0, it matches a wide range of
