ffmpeg set watermark using java
20 mai 2020, par SynixQueenI want to add a watermark( like .png) to a video.
This is the way for the command line :





ffmpeg -i input.mp4 -i watermark.png -filter_complex "overlay=1500:1000" output.mp4





found >here<



my Implementation so fairs like that :



FFmpegResult result = FFmpeg.atPath(Setup.getBin())
 .addInput(UrlInput.fromPath(inFile.toPath()))
 .addInput(UrlInput.fromPath(picture.toPath())
 .setDuration(10, TimeUnit.SECONDS)) // set duration time
 .setComplexFilter(FilterGraph.of(
 Filter.withName("overlay")
 .addArgument("20","20")
 .addOutputLink("lowerright")
 ))
 .addOutput(UrlOutput.toPath(output.toPath()))
 .execute();



at the point .setComplexFilter I am unsure I cannot find any sources to get this right atm 
like here >FFmegDokumentation<



any ideas ?

ffmpeg crashes on crossfades between 3 clips if 2 clips coming from same input file [closed]
14 avril 2020, par ErikI observed that ffmpeg 4.2.2 (macOS) crashes in particular cases of crossfades between clips, if one clip comes from file
1.dv, and two clips are cut out of file2.dv, as shown below :


ffmpeg -f lavfi -i color=black:size=720x576:duration=11:rate=25 -i 1.dv -i 2.dv -filter_complex "\
 [1:v]trim=5:10,setpts=expr=PTS-STARTPTS,yadif,fade=alpha=1:d=2:st=3:type=out,setpts=expr=PTS-STARTPTS,fifo[s5];\
 [2:v]split=2[s7][s8];\
 [s7]trim=5:10,setpts=expr=PTS-STARTPTS,yadif,fade=alpha=1:d=2:type=in,fade=alpha=1:d=2:st=6:type=out,setpts=expr=PTS-STARTPTS+(3/TB),fifo[s15];\
 [s8]trim=12:17,setpts=expr=PTS-STARTPTS,yadif,fade=alpha=1:d=2:type=in,setpts=expr=PTS-STARTPTS+(6/TB),fifo[s22];\
 [0:v][s5]overlay=eof_action=repeat[s6];\
 [s6][s15]overlay=eof_action=repeat[s16];\
 [s16][s22]overlay=eof_action=repeat[s24];\
 [1:a]atrim=5:10,asetpts=expr=PTS-STARTPTS[s26];\
 [2:a]asplit=2[s27][s28];\
 [s27]atrim=5:10,asetpts=expr=PTS-STARTPTS[s30];\
 [s28]atrim=12:17,asetpts=expr=PTS-STARTPTS[s33];\
 [s26][s30]acrossfade=d=2[s31];\
 [s31][s33]acrossfade=d=2[s36]" \
 -map "[s24]" -map "[s36]" -ab 128k -acodec aac -crf 23 -movflags faststart -preset medium -tune film -vcodec libx264 -aspect 1024:576 out.mp4 -y



The order makes a difference : if the two clips from
2.dvare used first and then the clip from1.dvis appended, everything works fine. Also, if all clips are coming from different files.


ffmpeg 3.4.6 (ubuntu 18.04) shows no issues in any case.



A self-compiled ffmpeg version N-97322-gb1699f4 (commit 2020-04-13) works with short clips as above, but crashes if one of the two clips taken from
2.dvis getting longer. In my tests 1500 frames (64 sec) is OK, 1700 (68 sec) leads to a segmentation fault. That is, if you replace in the command line above :


- 

[s7]trim=5:10...->[s7]trim=0:68and accordingly[s27]atrim=5:10...->[s27]atrim=0:68







Interestingly, the length of the clip taken from
1.dvdoes not play a role.


The ffmpeg output shows about 20 times :



frame= 0 fps=0.0 q=0.0 size= 0kB time=00:00:00.00 bitrate=N/A speed= 0x 



before it continues (seg fault case) :



frame= 4 fps=0.3 q=0.0 size= 0kB time=00:00:00.00 bitrate=N/A speed= 0x 
frame= 24 fps=1.6 q=0.0 size= 0kB time=00:00:00.00 bitrate=N/A speed= 0x 
frame= 25 fps=1.5 q=0.0 size= 0kB time=00:00:00.00 bitrate=N/A speed= 0x 
frame= 34 fps=1.9 q=0.0 size= 0kB time=00:00:00.00 bitrate=N/A speed= 0x 
frame= 36 fps=2.0 q=0.0 size= 0kB time=00:00:00.00 bitrate=N/A speed= 0x 
frame= 39 fps=2.1 q=0.0 size= 0kB time=00:00:00.00 bitrate=N/A speed= 0x 
frame= 40 fps=2.0 q=0.0 size= 0kB time=00:00:00.00 bitrate=N/A speed= 0x 
frame= 40 fps=2.0 q=0.0 size= 0kB time=00:00:00.00 bitrate=N/A speed= 0x 
frame= 40 fps=1.9 q=0.0 size= 0kB time=00:00:00.00 bitrate=N/A speed= 0x 




success case :



frame= 5 fps=0.4 q=0.0 size= 0kB time=00:00:00.00 bitrate=N/A speed= 0x 
frame= 42 fps=3.2 q=28.0 size= 0kB time=00:00:00.00 bitrate=N/A speed= 0x 
frame= 53 fps=3.9 q=28.0 size= 0kB time=00:00:00.36 bitrate= 2.9kbits/s speed=0.0264x 
frame= 65 fps=4.6 q=28.0 size= 0kB time=00:00:00.84 bitrate= 1.2kbits/s speed=0.0594x 
... 



Slightly older versions included in the newest MacOS builds from zeranoe.com (git-2020-04-13-59e3a9a) and evermeet.cx (N-97308-g14dd0a9057-tessus, from 2020-04-12) are working nicely - also on my production cases (longer clips).



Any feedback would be appreciated !

VLC - standard output 'dst=-' stopped working
2 juin 2020, par gdogg371Using VLC 3 I had the following command working perfectly a few months back :



"G:\VLC\vlc" --ffmpeg-hw --avcodec-hw=any dshow:// :dshow-vdev="Video (00 Pro Capture HDMI 4K+)" :dshow-adev="Audio (2- 00 Pro Capture HDMI 4K+)" :dshow-threads=8 :dshow-aspect-ratio=16\:9 :dshow-size="3840x2160" :dshow-pixel_format=yuv444p16le :dshow-tune=film :dshow-preset=lossless :dshow-profile=main10 show-vcodec=hevc_nvenc :dshow-fps=50 :dshow-crf=0 :dshow-acodec=mp4a :dshow-stereo-mode=5 :dshow-force-surround-sound=0 :dshow-ab=128 :dshow-samplerate=44100 :no-dshow-config :live-caching=300 --sout "#transcode{venc=ffmpeg,vcodec=mp2v,threads=8,aspect=16:9,width=3840,height=2160,fps=50,acodec=a52,ab=1500,channels=6,samplerate=48000,soverlay}:standard{access=file,dst=-,mux=ts}"



...however
dst=-suddenly seems to be causing a problem. I get the following error :


-- logger module started --

Previous behaviour observed was that VLC would open and start streaming. The purpose of this exercise is to pipe the VLC output into a PVR called NPVR.



I have tried uninstalling VLC and downloading a fresh install, but I still have the same issue. Any ideas ?
