bash variable changes in loop with ffmpeg
17 septembre 2018, par MikeI wrote a skript to quickly create short preview clips from vides I recorded on timestamps that I found worth checking out later for cutting.
My file with the timestamps is written like thisFILE_NAME1#MM:SS MM:SS
FILE_NAME2#MM:SS MM:SS MM:SS MM:SSexample :
MAH01728#02:47 03:34 03:44 05:00 06:08 06:55
The script looks like this :
#!/bin/bash
while read f
do
file=$(echo $f | cut -d"#" -f1)
filename=${file}".MP4"
timestamps=$(echo $f | cut -d"#" -f2)
for time in $timestamps
do
ffmpeg -ss 00:${time}.0 -i "orig/${filename}" -c copy -t 10 "preview/${file}_${time}.MP4"
done
done < $1The script gets half of the previews that I want and on the other the filename is messed up and ffmpeg complains that the file is not found :
orig/714.MP4: No such file or directory
orig/00:58 01:25.MP4: No such file or directorySo I modified the script for trouble shooting and just put an echo in front of the ffmpeg command - now all file names are correct. What am I missing ?
ffmpeg -ss 00:01:47.0 -i orig/MAH01714.MP4 -c copy -t 10 preview/MAH01714_01:47.MP4
ffmpeg -ss 00:02:00.0 -i orig/MAH01713.MP4 -c copy -t 10 preview/MAH01713_02:00.MP4
ffmpeg -ss 00:00:58.0 -i orig/MAH01712.MP4 -c copy -t 10 preview/MAH01712_00:58.MP4
ffmpeg -ss 00:01:25.0 -i orig/MAH01712.MP4 -c copy -t 10 preview/MAH01712_01:25.MP4 -
webmdashenc : Fix UTCTiming Element
28 avril 2015, par Vignesh Venkatasubramanianwebmdashenc : Fix UTCTiming Element
Remove the direct profile from UTCTiming element. Per DASH spec,
direct profile value should be the time at which the request was
made to the server and not the time at which the manifest was
written. So ffmpeg cannot write this value. This patch removes
the direct profile and write the UTCTiming element with the http
profile only if a URL is passed as a parameter. Update the fate
test to reflect this change.Signed-off-by : Vignesh Venkatasubramanian <vigneshv@google.com>

.mpd deleted after played
18 novembre 2020, par thxboxI would like to stream mp4 file with .mpd file. I installed MP4Box to convert mp4 to .mpd file, with this command


P4Box -dash 4000 -frag 4000 -dash-profile onDemand -segment-name out-seg -time-shift -1 -out prev_video.mpd prev_video.mp4



on my Ubuntu server


I also use nginx-rtmp-module to do video streaming.


My problem is after I play .mpd file with VLC Player then .mpd file was auto deleted.
so question is, is it possible to keep .mpd in my server ? or I miss some configuration while convert .mp4 to .mpd with MP4Box


Thank
