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 concatenation with -filter_complex
16 octobre 2018, par IgniterI’ve seen several similar questions but none of them actually helped in my case.
Getting this error while trying to join 1 audio and 4 video files of different nature and resolutions.ffmpeg -i 0.mp3 -i 1.mp4 -i 2.mkv -i 3.mkv -i 4.webm \
-filter_complex [0:a:0][1:v:0][2:v:0][3:v:0][4:v:0]concat=n=5:v=1:a=1[outv][outa] \
-map "[outv]" -map "[outa]" output.mp4All this gives the following error :
Stream specifier ':a:0' in filtergraph description [0:a:0][1:v:0][2:v:0][3:v:0][4:v:0]concat=n=5:v=1:a=1[outv][outa] matches no streams.
Straight concatenation
-i "concat:0.mp3|1.mp4..."
also doesn’t work as expected due to different resolutions and video formats. All methods syntax was taken from official documentation but there should be something that I’ve missed here.Full output log :

Why this shell command doesn't work ? ('command' works but 'command|cat' doesn't work)
16 octobre 2018, par yabeeProblem
The following code outputs like...
$ ffprobe -show_frames -select_streams v test.mp4 2>/dev/null|grep -A 2 key_frame=1
key_frame=1
pkt_pts=0
pkt_pts_time=0:00:00.000000
--
key_frame=1
pkt_pts=41041
pkt_pts_time=0:00:01.710042
--
key_frame=1
pkt_pts=64064
pkt_pts_time=0:00:02.669333
--
key_frame=1
pkt_pts=87087
pkt_pts_time=0:00:03.628625
--
...But the folowing one outputs nothing.
$ ffprobe -show_frames -select_streams v test.mp4 2>/dev/null|grep -A 2 key_frame=1|cat
And...
$ ffprobe -show_frames -select_streams v test.mp4 2>/dev/null|grep key_frame=1
key_frame=1
key_frame=1
key_frame=1
key_frame=1
$ ffprobe -show_frames -select_streams v test.mp4 2>/dev/null|grep key_frame=1|cat
# Nothing outputted.Why ?
Expected result
What actually I want to do is
$ ffprobe -show_frames -select_streams v test.mp4 2>/dev/null|grep -A 2key_frame=1|grep time
pkt_pts_time=0:00:00.000000
pkt_pts_time=0:00:01.710042
pkt_pts_time=0:00:02.669333
pkt_pts_time=0:00:03.628625
...But its result is
$ ffprobe -show_frames -select_streams v test.mp4 2>/dev/null|grep -A 2key_frame=1|grep time
# Nothing outputted.Grep works correctory exept it’s after ffprobe.
$ seq 30|grep 1|grep 2

Simple multimedia streams analyzer
usage: ffprobe [OPTIONS] [INPUT_FILE]
You have to specify one input file.
Use -h to get full help or, even better, run 'man ffprobe'.What is problem ?
Does grep or ffprobe change its behavior by existence of pipe
in this case
?
Thanks. - Bash on Ubuntu on Windows 10 Pro

Evolution #4203 (En cours) : Utiliser le type email sur les champs concernés en HTML5
25 octobre 2018, par b bComme indiqué dans cet article https://www.smashingmagazine.com/2018/10/form-design-patterns-excerpt-a-registration-form/ :
The input’s type attribute is set to email, which triggers an email-specific onscreen keyboard on mobile devices. This gives users easy access to the @ and . (dot) symbols which every email address must contain.
On devrait donc, si la config HTML5 est active (voir ce que je dis à ce sujet dans #4202), utiliser ce type sur les inputs des emails (comme c’est déjà le cas dans saisies).
