Cutting video with FFMPEG produces corrupted video file [closed]
5 juillet 2024, par m0ntr3Im using FFmpeg library for trimming videos. The problem comes when I try to get a thumbnail from that video using MediaMetadataRetriever - getFrameAtTime() ; and on my logcat I can see this error - getFrameAtTime : videoFrame is a NULL pointer. This is the command I use to cut/trim the video files - "-ss", TrimmerUtils.formatCSeconds(lastMinValue),
"-i", String.valueOf(filePath),
"-t",
TrimmerUtils.formatCSeconds(lastMaxValue - lastMinValue),
"-async", "1", "-strict", "-2", "-c", "copy", outputPath
Im using Android Studio with Java if that does matter. Im only assuming its producing a corrupt file.


If someone can help me that would be very appreciated !

Overlay streaming video on another video with ffmpeg
9 août 2017, par user3354787I am running a robot that uses fmpeg to send straming video to letsrobot.tv You can see my bot on the website called patton II. I want to overlay a video HUD on the stream.
I have found a link explaining how to do this, however I do not know how to do it with a streaming video as input instead of a single image file.
This is the command that is currently being used to stream the video :
overlayCommand = '-vf dynoverlay=overlayfile=/home/pi/runmyrobot/images/hud.png:check_interval=500'
videoCommandLine = '/usr/local/bin/ffmpeg -f v4l2 -framerate 25 -video_size 640x480 -i /dev/video%s %s -f mpegts -codec:v mpeg1video -s 640x480 -b:v %dk -bf 0 -muxdelay 0.001 %s http://%s:%s/hello/640/480/' % (deviceAnswer, rotationOption, args.kbps, overlayCommand, server, videoPort)
audioCommandLine = '/usr/local/bin/ffmpeg -f alsa -ar 44100 -i hw:1 -ac 2 -f mpegts -codec:a mp2 -b:a 32k -muxdelay 0.001 http://%s:%s/hello/640/480/' % (server, audioPort)
