Other interesting software
13 avril 2011, parWe don’t claim to be the only ones doing what we do ... and especially not to assert claims to be the best either ... What we do, we just try to do it well and getting better ...
The following list represents softwares that tend to be more or less as MediaSPIP or that MediaSPIP tries more or less to do the same, whatever ...
We don’t know them, we didn’t try them, but you can take a peek.

FFMPEG, Creating an MPEG-DASH stream with existing inputs
10 septembre 2019, par kitenseiI am trying to generating a
DASH .mpdfile 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) :

ffmpeg encoded hls makes audio and video progressively out of sync
21 septembre 2020, par eschieWhen 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 ?
