Jitsi-Meet: Schlechte BildqualitÀt


Cadet 4th Year
Dabei seit
Nov. 2015
Hallo 🙂

Ich nutze Jitsi-Meet und alle Teilnehmer haben eine schlechte BildqualitĂ€t. Die Kameras unterstĂŒtzen alle HD (720p).

Die QualitÀt schwank zwischen 180p und 360p (SD-QualitÀt). Sie schaltet aber nie auf HD um.

Simulcast ist aktiv. Schalte ich dies ab, ist alles in HD, aber Leute mit schlechter Internetverbindung haben dann das Nachsehen.

In Jitsi habe ich als Auflösung:
  • ideal: 1080
  • max: 1080
  • min: 240
Das heißt ja, dass die Auflösung zwischen 240 und 1080p sein darf.

Wo kann das Problem liegen? 😬

Hier mal meine Config:

meet.example.com ist hier nur als Beispiel-Domain ;)
Ich habe das, was ich geĂ€ndert habe, unter dem auskommentierten eingefĂŒgt, damit ich schneller sehe, was ich geĂ€ndert habe. Beispiel-Zeile: 159-167...

Vieles ist ab Werk tatsÀchlich auskommentiert. Einiges ist aber auch einkommentiert (sagt man das so?)

Die Frage wĂ€re, was muss ich Ă€ndern, damit die BildqualitĂ€t besser wird? 🙂
Geh doch mal alle Einstellungen aufmerksam durch.

Ich sehe z.B. in Zeile 137 und 141 Potential.

Deine Einstellungen hinsichtlich der Auflösung (ideal, max und min) wĂŒrde ich mal auf 720 fĂŒr max und ideal umstellen (die Kameras können laut deiner Info ja eh nur 720p).

Zeile 206 wĂŒrde ich mal deutlich reduzieren.

Zeile 338 bis 340 solltest du dir noch mal anschauen.

Ansonsten: wie sieht des denn mit der default config aus? Stimmt da die QualitÀt?
Zitat von Hansdampf12345:
Z137 habe ich nun auf 720p, Z141 auf 20. Selbst bei -1, schaltet die QualitÀt nicht auf HD.

Zitat von Hansdampf12345:
Zeile 206 wĂŒrde ich mal deutlich reduzieren.
Ich habe dies deswegen auf max. 60 FPS eingestellt, da wir auch hĂ€ufig BildschirmĂŒbertragungen von Spielen, etc. machen 😉

In den Werkseinstellungen ist dessen Übertragung sonst nur am Ruckeln.

Zitat von Hansdampf12345:
Zeile 338 bis 340 solltest du dir noch mal anschauen.
Ich habe mal high auf 360 gesetzt, aber das Ă€ndert nur die Info-Anzeige. Sprich, dann steht als Info, dass 360p schon HD-QualitĂ€t sei. Hab's dann nach dem Test wieder rĂŒckgĂ€ngig gemacht, da dies an der eigentlichen QualitĂ€t nichts geĂ€ndert hat.

Zitat von Hansdampf12345:
Ansonsten: wie sieht des denn mit der default config aus? Stimmt da die QualitÀt?
Nein, deswegen habe ich die Standard-Einstellungen geÀndert. Ab Werk ist es schlimmer.

Dank den jetzigen Einstellungen schaltet er bei mehr als 2 Usern nicht mehr auf 180p um, sondern bleibt wenigstens bei 360p. Die QualitÀt geht dann kurze Zeit spÀter wieder auf 180p. Höher schaltet Jitsi nicht.

HD kann man nur nutzen, wenn man einen Benutzer als Vollbild anzeigt. In der Kachelansicht bleibt es bei max. 360p.

Hier mal meine neuen Einstellungen der genannten Zeilen:

// ...

resolution: 720,

// ...

maxFullResolutionParticipants: 20,

// ...

constraints: {
         video: {
             height: {
                 ideal: 720,
                 max: 720,
                 min: 240

// ...

minHeightForQualityLvl: {

240: 'low',
360: 'standard',
720: 'high'
// ...
Zuletzt bearbeitet:

es hilft vielleicht nicht unmittelbar weiter, aber die Symptome passen zu Beobachtungen mit einer eigenen jitsi-Instanz (ebenfalls mit simulcast aktiv).
Bei mir sieht es nach einem Browser-abhÀngigen Problem aus: die Umschaltung zwischen niedriger QualitÀt (wenn der Remote-Teilnehmer z.B. nur im Strip am Seitenrand sichtbar ist) auf höhere QualitÀt (wenn man den Remote-Teilnehmer in die Voll-Ansicht nimmt) funktioniert bei mir genau dann nicht, wenn der Remote-Teilnehmer Firefox verwendet und mehr als 2 Teilnehmer im Meeting sind (also kein p2p Meeting). Wechselt der betroffene Teilnehmer dann von Firefox auf Edge/Chrome, ist alles gut.

Wenn von vorneherein nur ein p2p Meeting mit 2 Teilnehmern stattfindet, dann wird auch vom Firefox immer mit der maximalen Video-QualitÀt gesendet.

Das Problem beschÀftigt mich schon lÀnger (selbst bei einem neu aufgesetzten jitsi mit default config und jitsi-Server und Clients im selben LAN), aber auf meet.jit.si ist es definitiv nicht vorhanden. Es sollte also eine Lösung geben.

Sollte die Beobachtung nicht zum Problem des Threads passen, dann bitte einfach ignorieren.
