• FFMPEG, Creating an MPEG-DASH stream with existing inputs

  10 septembre 2019, par kitensei

  I am trying to generating a DASH .mpd file from multiple inputs (2 videos, 1 audio) without any success..

  What I’d like to do it’s simple getting the streams and create an mpd file without any re encoding since I’ve already my sources ready.

  The output seems to work in rxplayer, but I do get a lot of errors (see log below).

  Here are my 3 sources (taken from http://dash-mse-test.appspot.com/media.html) :

  And here how I am "muxing" them together with an .mpd manifest :

• ffmpeg encoded hls makes audio and video progressively out of sync

  21 septembre 2020, par eschie

  When trying to encoding a source .mp4 to multiple bitrates and sizes for adaptive HLSv3 playback the resulting audio and video become progressively out of sync. When scrubbing to a later point it seems to reset, and stay in sync.

  



  I'm on the latest ffmpeg 4.2.1 via homebrew-ffmpeg, with the libfdk-aac codec. Note, this was also occurring with ffmpeg 4.1.

  The audio and video streams are marginally off, would that cause this problem ?

• how to solve ffmpeg video merging complain about parameters mismatching

  22 septembre 2019, par mohammad rostami siahgeli

  I’m trying to concatenate an intro video to a main video. Here’s my command :

  ffmpeg -i C:\Temp\intro.mp4 -i C:\Temp\main.mp4 -filter_complex "[0:v:0][0:a:0][1:v:0][1:a:0]concat=n=2:v=1:a=1[outv][outa]" -map "[outv]" -map "[outa]" C:\Temp\output.mp4

  When I run this command in cmd, I get the following error :

  I’m not a video ninja. I know parameters are different, but I have no idea after hours of search on how to solve this. A lot of online video services concatenate these two videos and give me a reasonable result. They have a GUI though. I need to do it in code, so that I can automate it.

  How can I solve these errors ?

  Update : This is the second error :
