Re: [FFmpeg-user] Webcam capture
Since you have an AMD cpu/apu, one last resort that I can think of is to capture webcam with hardware acceleration. Extracted from https://trac.ffmpeg.org/wiki/Hardware/VAAPI Also, you need to verify what "-vaapi_device" is the correct one for your machine. The wiki has much more information. "Camera Capture Capture a raw stream from a V4L2 camera device and encode it as H.264: $ ffmpeg -vaapi_device /dev/dri/renderD128 -f v4l2 -video_size 1920x1080 -i /dev/video0 -vf 'format=nv12,hwupload' -c:v h264_vaapi output.mp4 ...

Re: [FFmpeg-user] Webcam capture
Hello, as an alternative, you can display your webcam at screen with mplayer $ mplayer tv:// -tv driver=v4l2:width=640:height=480:device=/dev/video0:fps=30:outfmt=yuy2 -noborder -geometry 640x480+0+0 and record your screen+audio with ffmpeg (here I'm using pulseaudio because of the "noise-reduction") $ ffmpeg -thread_queue_size 1024 -f pulse -sample_rate 44100 -i default -video_size 640x480 -probesize 10M -framerate 30 -thread_queue_size 512 -f x11grab -i :0.0 -c:a aac -b:a 128k -c:v libx264 -vf "format=yuv420p" -crf 0 -preset ultrafast output.mp4 You can use $ uvcdynctrl -f to identify which resolution/fps your webcam supports and edit commands above to your needs.

[FFmpeg-user] replace several lines by one using the filter_complex
Hello, I have a video that I need to extract two parts of it and merge together those parts. I can accomplish this using the TRIM/ATRIM filter together with the concat demuxer: $ ffmpeg -i video.mp4 -vf "trim=start=7:end=1173,setpts=PTS-STARTPTS" -af "atrim=start=7:end=1173,asetpts=PTS-STARTPTS" part1.mp4 $ ffmpeg -i video.mp4 -vf "trim=start=1260:end=1430,setpts=PTS-STARTPTS" -af "atrim=start=1260:end=1430,asetpts=PTS-STARTPTS" part2.mp4 After this I create a file input.txt (duration found with ffprobe): file 'part1.mp4' duration 1166.02file 'part2.mp4'duration 170.02 And finish with $ ffmpeg -f concat -i input.txt -c copy video_final.mp4 This sequence of steps work as expected but I would like to know if it is possible to use the filter_complex with only "one line command" to achieve same result ?

It looks like that ffmpeg is not respecting "extract from 0 to 26" and instead doing something like "well, I will start at 12.6 and will stop at 26" Forcing with -copyinkf as suggested by Moritz, although the extracted part has, indeed, 26 seconds, there is only a "gray screen" from 0 to 12.6 and after that it plays well. The main.mp4 file plays normal.

Re: [FFmpeg-user] extract first 26 seconds not workings as expected
Hello
>You may want to try the option "-copyinkf" ("copy initial
>non-keyframes") when using "-c copy".
I tried with this option, but the extracted part was "grayed" at the beginning.
The only workaround that I found that worked was
$ ffmpeg -i main.mp4 -vf "trim=start=0:end=26" part1.mp4
but re-encoded is needed.
As you pointed out, the file has 23.80 fps, and this may be the problem.
I created a sample video (53.63 seconds) if someone want to try some code on it.
The video of the original post and this one were created using
SimpleScreenRecorder
Perhaps some configuration on the GUI is not properly set to produce a "good
video file".
Will try to play with it a bit.
Kind regard,
Leonardo

[FFmpeg-user] Producing smooth video from images
Hello, I have a sequence of images, image001.png to image945.png, and I am using this command to produce a video: ffmpeg -framerate 60 -i image%03d.png -c:v libx264 -pix_fmt yuv420p -vf scale=1920:1080,fps=60 -r 60 video.mp4 The video is fine but I would like to improve it. I was thinking in some kind of "motion blur" or a better sense of motion. The filters minterpolate and tblend seem to be what I am looking for, but I don't know how to use nor which is better. Any tips?

[FFmpeg-user] Last frame with wrong duration - video from images
Hello, I have two images named figur001.png and figur002.png that I want to make a video of 10 seconds, each figure being displayed for 5 seconds. After command ffmpeg -framerate 1/5 -i figur%03d.png -c:v libx264 -pix_fmt yuv420p -r 30 -vf scale=1920:1080 video.mp4 It seems that the full duration is 10 seconds because ffmpeg displays this: Duration: 00:00:10.00, start: 0.00, bitrate: N/A However, using mplayer or vlc to play the video, the first image is showed during 5 seconds (as it should be) but the second image no. The second image is displayed by less than a second (0.1s maybe) Any ideas on how to solve this? Kind regards, Leonardo ___ ffmpeg-user mailing list ffmpeg-user@ffmpeg.org https://ffmpeg.org/mailman/listinfo/ffmpeg-user To unsubscribe, visit link above, or email ffmpeg-user-requ...@ffmpeg.org with subject "unsubscribe".
