Getting a single mp4 file from dash and a mpd file [closed]
15 août 2023, par Govind SharmaI want to ask that I have downloaded data which contains audio and video data separately like 1.mp4, 2.mp4 etc in both audio and video folders. enter image description here
I also have it's .mpd file. How can I play this video ? or is there any way I can combine both videos and audio files in a single one. Single file for e.g. 1.mp4 video or audio nothing seem to play.

Reading frames from MP4 segment (.m4s). or Dash Segment [closed]
24 septembre 2020, par Vamsi Krishna RayapatiGenerally we do it by


copying
init.mp4
andsegment1.m4s
to a video file and extract frames in that video

It works fine. But it requires a temporary file


I want to edit
segment1.m4s
directly

''' my idea is to decode the video
Direclty with out using init file '''


Help me .how to do it ?

Bash script : automate ffmpeg encoding for mpeg-dash
13 février 2018, par Massimo VantaggioI’m writing a bash file to create video encoding and concatenation for dash live streaming use,
Basically it read an input video folder, encodes all videos into three resolution formats, after that it concatening them to create three adaption sets.DIAGRAM :
This script checks for fps conformance,
force/scaling resolution if the input is not 1920 x 1080p,
Insert the channel logo png,
Cut the end of all videos input in order to make them finish with closed gop, this to ensure that there are not videos with audio and video track with different lenght.
ISSUE :
Actually I’m not sure that the concatenation process respects the closed GOP alignment as it after the encoding..
I try to cut also the end of the concatenation result in order to make it finish without decimals on a closed gop too, but im unable to erase all decimals from the total duration :total duration in seconds: 826.795000
total duration corrected in seconds: 826But the real duration measured by ffprobe is
824.044000
I try to check keyframes alignment with mp4box has they teach without any result :
MP4Box -info TRACK_ID source1.mp4 2>&1 | grep GOP
This is the first time that i work with "video scripts" and probably i don’t know what input to give for TRACK_ID
BASH SCRIPT :
#!/bin/bash
#CANCAT 0.2
cd input
times=()
fps=()
for f in *.mp4; do
_t=$(ffprobe -i "$f" -show_entries format=duration -v quiet -of csv="p=0")
times+=("$_t")
_f=$(ffmpeg -i "$f" 2>&1 | sed -n "s/.*, \\(.*\\) fp.*/\\1/p")
fps+=("$_f")
done
#SUM ALL DURATIONS
TOTALDURATION=$( echo "${times[@]}" | sed 's/ /+/g' | bc )
#DELETE DECIMAL
DURROUND=$(echo "$TOTALDURATION" | cut -d'.' -f1)
#GET REST OF DIVISION BY 2 AS GOP
TOTDELTA="$((DURROUND%2))"
#SUBTRACT DELTA FROM TOTAL DURATION
TOTDUR="$(($DURROUND-$TOTDELTA))"
#GET NUMBER OF ELEMENTS IN FPS ARRAY
tLen=${#fps[@]}
#CHECK FPS EQUALITY
for tLen in "${fps[@]:1}"; do
if [[ $tLen != ${fps[0]} ]]; then
printf "WARNING: VIDEO’S FRAME-RATE ARE NOT EQUALS, THE PROCESS CAN’T START."
printf "%s\\0" "${fps[@]}" |
sort -zu |
xargs -0 printf " %s"
printf "\\n"
exit 1

rm *.mp4
rm *.txt
echo "CONCAT COMPLETED:"
echo "frame-rate: $fps"
echo "total duration in seconds: $TOTALDURATION"
echo "total duration corrected in seconds: $TOTDUR"The full file with relative folders :
There is someone who can help me to understand why I can not eliminate the decimals of the total duration during concat ?
And how to check overall keyframes allignment ?
Also any impovement that i ignore is welcome !Thanks a lot !
