  • FFMPEG, how to get rid of "broken pixels" in videos ?

    5 avril 2021, par Sergi Fernàndez

    I'm using the following command to trim the video and reduce it's size, while keeping the visual quality :

    


    ffmpeg -hwaccel cuda -y -hide_banner -ss 00:02:45.2000000 -i .\video\410.mkv -t 00:20:29.3090000 -map 0:v -c:v hevc_nvenc -preset slow -map 0:a -codec:a aac -x265-params crf=16 -metadata:s:v:0 title=1080p -metadata:s:v:0 language=ja -metadata:s:a:0 title=Japanese -metadata:s:a:0 language=ja -tune zerolatency .\processing\410.mkv

    


    It's been working pretty good, it gets encoded fast and it looks exactly as the input video, but at certain moments you can find this kind of problems with the pixels :

    If I open the video with Windows Media Player, VLC, Photos app, etc... they all show the video with this pixel issue. However, if i open the damaged video using Wondershare Filmora, you can't see that issue at all, and it looks just as the original video. This is how it looks like in Wondershare Filmora :

    How can that be possible ? Any way to fix this for all video players ? If possible I would like to avoid CPU encoding, as it takes more than 2 days to encode a single video... Thanks !

    


  • Stream Multiple Videos Using FFMPEG

    21 août 2020, par Devin Dixon

    I am currently streaming videos as such :

    


    


    ffmpeg -re -i video.mp4 -maxrate 3000k -bufsize 6000k -c:v libx264
-preset superfast -tune zerolatency -strict -2 -c:a aac -ar 44100 -f flv rtmp::locahost/live/123

    


    


    Let's say I have video1.mp4, video2.mp4, video3.mp4. Each might have a different resolution.

    


    Is there a way to stream them one right after each other in one command ?

    


  • Uploading & Processing Videos in Rails app on Heroku

    8 octobre 2015, par scientiffic

    In my Rails app, users can upload videos. The videos need to get converted to mp4s to ensure they can play across browsers, and they are hosted on AWS S3.

    If the video conversion (using ffmpeg) happens quickly, the resulting mp4 is rendered directly on the page so the user can immediately view the uploaded video. Sometimes, though the conversion takes long enough that I get Heroku H12 errors (request timeout), which prevents the video preview from appearing.

    Is there a recommended workflow for dealing with processing larger files in a Rails app using Heroku ?

    The option that immediately comes to mind is processing in a background task using something like Sidekiq, but then the user doesn’t receive feedback when the upload is complete.
