Récupération d’informations sur le site maître à l’installation d’une instance
26 novembre 2010, parUtilité
Sur le site principal, une instance de mutualisation est définie par plusieurs choses : Les données dans la table spip_mutus ; Son logo ; Son auteur principal (id_admin dans la table spip_mutus correspondant à un id_auteur de la table spip_auteurs)qui sera le seul à pouvoir créer définitivement l’instance de mutualisation ;
Il peut donc être tout à fait judicieux de vouloir récupérer certaines de ces informations afin de compléter l’installation d’une instance pour, par exemple : récupérer le (...) -

Can't play MP4 after download
14 août 2018, par joeI am using a downloader program in Firefox to download videos playing in Firefox. Most of the time final MP4 is playable. But sometimes I get MP4 file that looks good(shows file size) but shows no length of video in file explorer.
I get this error log.
Could not get information from media 'ESPN 2 (HD) Live Stream Channel' from file 'C:\Download\dwHelper\ESPN 2 (HD) Live Stream Channel.mp4'. The file might be corrupted.

[mov,mp4,m4a,3gp,3g2,mj2 @ 00000000024c3900] moov atom not found
C :\Download\dwHelper\ESPN 2 (HD) Live Stream Channel.mp4 : Invalid data found when processing input
It looks like moov atom is missing thus can’t aggregate PART file into final playable MP4.
I understand that during download, PART file is created. Then later PART is aggregated into final MP4.
So question is how can I make this MP4 to play ?
or is it impossible to play cus moov atom was not properly downloaded ?Any thoughts ?

ffmpeg produces "is_avc" = false with h264_nvenc & tee muxer
14 août 2018, par Areeb111I am using ffmpeg for encoding MKV (Matroska Video files) to 2x MP4 (H264 - 720p Main@L4) & (H264 - 360p Baseline@L3.1).
Having really strange problem when using
-c:v h264_nvenc
andtee muxer
then the produced output file is havingis_avc=false
even i have checked the same input matroska file with another server running with Intel QuickSync-c:v h264_qsv
with the same command then the produced output file isis_avc=true
.The main goal that i want the
is_avc=true
is because the files must be played usingnginx-vod-module
which requires the AVC video format to be streamed.Steps to reproduce the problem :
- Custom ffmpeg build with NVENC support

- Running ffprobe for the output file to check "is_avc" :
./ffprobe -v quiet -print_format json -show_format -show_streams testoutput.mp4

My current ffprobe output results are :
./ffprobe -v quiet -print_format json -show_format -show_streams testoutput.mp4

Please anyone can help me why is the output video file is getting "is_avc=false" ?
Is there any option to force it ?
Thank you

Converting DTS to AAC with ffmpeg shifts spoken audio to the right
18 août 2018, par GiuseppeI am using ffmpeg to convert
mkv
movies tomp4
, like so :$ ffmpeg -i source.mkv -c:v copy -c:a aac destination.mp4
By doing this, the audio stream gets converted from the original DTS :
Stream #0:1: Audio: dts (DTS), 48000 Hz, 5.1(side), fltp, 1536 kb/s (default)
To AAC :
Stream #0:1(und): Audio: aac (LC) (mp4a / 0x6134706D), 48000 Hz, 5.1, fltp, 394 kb/s (default)
The resulting file plays just fine, except that the spoken audio (what I am assuming would be sent to the central channel in a 5.1 configuration) sounds clearly shifted to the right, when listening through the MacBook’s built-in speakers or my stereo headphones. Note that music and other sound effects appear unaffected, properly balanced. Also note that I have been able to reproduce this behavior with a variety of source files.
