The latest version of FFMPEG is 3.1.1, Just released before 12 days. So i think there is no readily available demo like this old one. We need to build the FFMPEG library on our own. Some questions i found just pasting here that might help you. (Not tested) How to Build FFmpeg for Android Compiling … Read more
You are encountering several issues: Not all filters support sendcmd. You can see which filters support sendcmd with ffmpeg -filters. Look for a “C” to the left of the filter name. Additionally, only certain filter options (aka sendcmd “commands”) can be used with sendcmd. See the FFmpeg filter documentation, or refer to man ffmpeg-filters, and … Read more
Am I suppose to create a separate .php file which then runs from the php cli to execute one of these functions? This is probably the way I would do it : the PHP webpage adds a record in database to indicate “this file has to be processed” and displays a message to the user … Read more
Start with Roman’s tutorial. Following changes apply to Windows: you should use the NDK make.exe, not the one from cygwin. So, I simply wrote d:/dev/Android/ndk/prebuilt/windows-x86_64/bin/make.exe in my build_android.sh. For some weird reason, I could not run make clean – but I simply chose to ignore this problem for now. Following the tutorial, don’t forget to … Read more

If you just want a ffmpeg command, try ffmpeg -i input.mov -i overlay.mov \ -filter_complex “[1:v]setpts=PTS-10/TB[a]; \ [0:v][a]overlay=enable=gte(t\,5):shortest=1[out]” \ -map [out] -map 0:a \ -c:v libx264 -crf 18 -pix_fmt yuv420p \ -c:a copy \ output.mov This starts the overlay at 5 seconds with the overlaid video start point being 00:15. setpts=PTS-10/TB is setpts=PTS+(overlay_delay-video_trim_in)/TB overlay=enable=gte(t\,5) is … Read more
Since most Cameras store their rotation/orientation within the exif-metadata, i would suggest using exifttool and the a ruby wrapper gem called mini_exiftool which is actively maintained. Install exiftool: apt-get exiftool || brew install exiftool || port install exiftool or use what ever package manager is available Install mini_exiftool: gem install mini_exiftool Try it: irb> require … Read more
With FFmpeg you can either: use pre-built .lib/.dll files and your binary produced with Visual Studio will be dependent on av*.dll files compile FFmpeg from source code into static libraries using non-Microsoft compiler, and then link to your Visual Studio project (mind the LGPL/GPL license in this case) You built your project as per item … Read more
Use the silenceremove filter. This removes silence from the audio track only – it will leave the video unedited, i.e., things will go out of sync Its arguments are a little cryptic. An example ffmpeg -i input.mp3 -af silenceremove=1:0:-50dB output.mp3 This removes silence at the beginning (indicated by the first argument 1) with minimum length … Read more

Otherwise the codec_name for all other streams in the file, such as audio, will be shown as well. -show_entries … Read more
