Cut audio clips and screen shots from the MP4 Timestapes

Lubium wrote a great source code. With the use of Streams, Consumer, Java 17. The library net.bramp.ffmpeg is well used. All operations with the help of parameters are reduced to one, batch processing works quickly. That’s exactly what I described in my task. And even better. thank you.

Project translated automatically. Log in or register, to view the original Artwork for an educational project (in the prototype phase). The best option (implementation) for creating a set of audio fragments and screen shots based on a video file needs to be explored and proposed. At the entrance, the program receives: - video file with one or more audio tracks - text file with subtitles - Arguments (audio track number, audio fadein/fadeout in milliseconds, see para. (see example) audioTrack=1 FadeIn=200 FadeOut=200 At exit: - audio fragments recorded in the folder (in mp3 format, bitrate the same as in the video) - screen shots recorded in another folder (png format, resolution same as video) I'm guessing we can do this with a ffpeg call. Then the Java control program you've written should untweet the subtitles, make all the necessary calls ffmpeg with the right parameters. Video for testing (Family Guy s1e1, 20min, 173Mb): https://drive.google.com/file/d/1tRRU51a9kjHC47we_Vunl4_1FxF6Wotd/view?usp=sharing Subtitles: https://drive.google.com/file/d/1CflWB9nJ_SZKahWf7an5SN4Tv22Cty/view?usp=sharing Assess how much it's going to cost to develop a prototype of this program. (Prototype means you don't want to try to do the code, the optimization, the functional diversity, you don't have to write tests - only if it's for yourself.) Clarification #1: Screen shots are taken from the video for every audio fragment. The timestamp screen is calculated as the mid-point of audiofragment.screenshotTimetamp =(audioEndTimemp-audioStartTimetamp)/2 Final objective is to create an audio comic book for the web. The generation of this comic book is a separate story. Clarification #2: You can use ffmpeg-cli-wrapper. Clarification #3: There is also a need to add fadein/fadeout for audio fragments so that they do not sound ripped. Apparently, you can use afade filter. Example of use: ffmpeg-i music.mp3-af"afade=t=in:st=0:d=0.5"out.mp3 ffmpeg-i music.mp3-af"afade=t=out:st=5:d=0.5"out.mp3 links to other examples So maybe we'll have to use ffpeg several times for each fragment: cut the fadeIn fadeOut compression into mp3
