MediaSPIP : Modification des droits de création d’objets et de publication définitive
11 novembre 2010, parPar défaut, MediaSPIP permet de créer 5 types d’objets.
Toujours par défaut les droits de création et de publication définitive de ces objets sont réservés aux administrateurs, mais ils sont bien entendu configurables par les webmestres.
Ces droits sont ainsi bloqués pour plusieurs raisons : parce que le fait d’autoriser à publier doit être la volonté du webmestre pas de l’ensemble de la plateforme et donc ne pas être un choix par défaut ; parce qu’avoir un compte peut servir à autre choses également, (...)

ffmpeg error while converting to mp4 Error while opening encoder for output stream #0.0
20 mars 2016, par JoshI am trying to convert various file types to mp4 to be displayed using ffmpeg, but i keep getting the error :
Error while opening encoder for output stream #0.0 - maybe incorrect parameters such as bit_rate, rate, width or height
Another piece that looks important is :
[libx264 @ 0x93caef0] broken ffmpeg default settings detected
[libx264 @ 0x93caef0] use an encoding preset (e.g. -vpre medium)
[libx264 @ 0x93caef0] preset usage : -vpre -vpre
[libx264 @ 0x93caef0] speed presets are listed in x264 —help
[libx264 @ 0x93caef0] profile is optional ; x264 defaults to high
The latest code I am running is :
ffmpeg -i source -s 320x240 -r 30000/1001 -b 200k -bt 240k -vcodec libx264 -coder 0 -bf 0 -refs 1 -flags2 -wpred-dct8x8 -level 30 -maxrate 10M -bufsize 10M -acodec libfaac -ac 2 -ar 48000 -ab 192k destination
I have seen a few other people with this issue, but their fixes didn’t work for some reason.
In case it matters : ultimately this will be used in php, though I am trying to get it working first via putty
EDIT: : Here is the full thing as requested(using a wmv, have tested wmv and flv) :
~ >> ffmpeg -i path.wmv -s 320x240 -r 30000/1001 -b 200k -r 29.97 -bt 240k -vcodec libx264 -coder 0 -bf 0 -refs 1 -flags2 -wpred-dct8x8 -level 30 -maxrate 10M -bufsize 10M -acodec libfaac -ac 2 -ar 48000 -ab 192k path.mp4

Generating DASH manifest with ffmpeg works in Docker exec shell but not in os.exec golang
22 février 2023, par InquisitorI am trying to generate a DASH manifest with ffmpeg using this command


/usr/bin/ffmpeg -f webm_dash_manifest -i ./480.webm -f webm_dash_manifest -i ./audio.webm -c copy -map 0:0 -map 1:0 -y -f webm_dash_manifest -adaptation_sets "id=0,streams=0 id=1,streams=1" ./manifest.mpd -loglevel repeat+level+verbose



I run this in go, in a docker container as shown :


func runFFmpeg(arguments []string) {
 arguments = append(arguments, "-loglevel", "repeat+level+verbose")
 cmd := exec.Command("ffmpeg", arguments...)

 fmt.Printf("cmd: %v\n", cmd)

 var out bytes.Buffer
 var stderr bytes.Buffer
 cmd.Stdout = &out
 cmd.Stderr = &stderr
 err := cmd.Run()

 if err != nil {
 log.Println(err)
 log.Println(stderr.String())
 }
}
runFFmpeg([]string{"-f", "webm_dash_manifest", "-i", "./480.webm", "-f", "webm_dash_manifest", "-i", "./audio.webm", "-c", "copy", "-map", "0:0", "-map", "1:0", "-y", "-f", "webm_dash_manifest", "-adaptation_sets", "\"id=0,streams=0 id=1,streams=1\"", "./manifest.mpd"})



But I get this output :


cmd: /usr/bin/ffmpeg -f webm_dash_manifest -i ./480.webm -f webm_dash_manifest -i ./audio.webm -c copy -map 0:0 -map 1:0 -y -copy_unknown -f webm_dash_manifest -adaptation_sets "id=0,streams=0 id=1,streams=1" ./manifest.mpd -loglevel repeat+level+verbose

It works perfectly however if I run it within docker exec (exec into the container and run the command in bash). Also, note in the last output that the command is well formed when I print it out from go. File permissions are also not the problem since the command to create the video variants works with os.exec i.e


runFFmpeg([]string{"-i", originalFilePath, "-c:v", "libvpx-vp9", "-keyint_min", "150", "-g", "150", "-tile-columns", "4", "-frame-parallel", "1", "-f", "webm", "-dash", "1", "-an", "-vf", fmt.Sprintf("scale=%s:%s", width, height), "-b:v", bitRate, "-dash", "1", "-y", destinationFilePath})
