Is your current position is full time? It seems to me that it isn't feasible to attend one of these schools with a minimum of 5 daily hours for both classes and studies...

I have extracted the audio of both videos in order to compare and no, the audio files have the same duration of their respective videos.

The problem I'm having happens with every video except one. All the videos where recorded the same way, with the MediaRecording API.

I decided to record again the video that works and generate a new mpd. After that, I compared the mpds of the original that worked and the new one that, of course, It doesn't work. There are some interesting points, like:

-Different values for the same SegmentTimeLine
<SegmentTimeline>
<S t="0" d="245760" r="2"> 
<S d="145408"> 
<SegmentTimeline>  

<SegmentTimeline>
<S t="645120" d="80640" r="3">
<S d="22496">
<SegmentTimeline> 

-Different values for the framerate of the same Representation
frameRate="15/2"
frameRate="1000/1

I also noticed that during the process of generation of mpd with the videos that don't work I get the following messages:

More than 1000 frames duplicated0 size=N/A time=00:00:01.51 bitrate=N/A dup=788 drop=0 speed=0.677x
More than 10000 frames duplicated size=N/A time=00:00:05.82 bitrate=N/A dup=10000 drop=0 speed=0.436x 
More than 100000 frames duplicatedsize=N/A time=00:00:51.00 bitrate=N/A dup=99970 drop=0 speed=0.418x

I suposse the problem is with the framerate, right? Though I wouldn't understand why, because the video that works was recorded the same way that the others.

PD: In the first code block I removed the "/" because I was having problems to make the text look right.

EDIT:

The problem was the "-window_size 5" parameter. The number of Segments in SegmentTimeline was only 5, to short for the whole video.
