How do I use ffmpeg to concatenate 2 videos and add a period of silence + black screen between them ?
29 avril 2022, par masotimeThere are several existing examples, but I'd like a single command that uses complex_filter to achieve the objective without doing extra things like generating blank video / audio files.


Looking around, this is the best I've come up with so far :


ffmpeg -i video1.mp4 -i video2.mp4 -filter_complex "color=black:s=960x540:d=1[b0];aevalsrc=0:d=1[s0];[0:v:0][0:a:0][b0][s0][1:v:0][1:a:0]concat=n=3:v=1:a=1[outv][outa]" -map '[outv]' -map '[outa]' out.mp4



My understanding of the breakdown of such a command is


- 

- specify 2 inputs
- define a complex filter
- define a black video stream of duration 1s and call it b0
- define a silent audio stream of duration 1s and call it s0
- pipe it through the concat filter with












- 

- First stream : [0:v:0][0:a:0] // video1.mp4
- Second stream : [b0][s0] // stuff I defined earlier
- Third stream : [1:v:0][1:a:0] // video2.mp4








- 

- define 2 output streams [outv][outa] for video and audio respectively
- combine them into out.mp4






All file inputs are correctly 960x540, all using the same audio and video codecs but ffmpeg gives me this error and starts using 100% CPU


More than 1000 frames duplicated



I think there's something wrong with the streams I'm defining in the filter - what's wrong ? Do I need to specify more parameters somewhere ?

ffmpeg mjpeg -> h.265 smeared color on output video file
14 mars 2023, par BobtheMagicMooseI am converting some old mjpeg videos (stored in .avi container) to h.265 (.mp4 container) but am noticing the colors are smearing. Using the terminal command :


ffmpeg -y -i "input-file.avi" -c:v libx265 -vtag hvc1 "output-file.mp4"


I get the following image (notice how the red and blue are stretched donward). There is a lot of motion in the scene, but the motion is mostly horizontal :




Any idea what might cause this ? The detail and resolution seem fine, just the colors are being interpreted weirdly.

Is this normal ? Shouldn't the encoding file had different info's about color primaries, transfer characteristics etc ?


Encoding video files i expected more accurate file informations.
