J'ai une grande collection de disques BluRay et je souhaite qu'elle soit insérée dans ma bibliothèque iTunes pour être lue sur AppleTV.
Je dois convertir les différents flux audio en un format approprié.
Mais il y a plusieurs messages d'erreur / avertissement que je dois gérer.
Voici quelques exemples de fragments de code:

Ne s'affiche que lorsque j'essaie de convertir les formats avec perte suivants: ac3, dts et eac3. Avec perte dts (comme DTS-HD haute résolution) je vais bien.
[out_0_0 @ 000000000046bc40] 100 buffers queued in out_0_0, something may be wrong.
N'apparaît que lorsque j'essaie de convertir TrueHD sans perte, mais que l'audio DTS-HD Master Audio sans perte convient parfaitement.

Ces messages sont toujours présents lorsque j'essaie de multiplexer tous les flux.
Vont-ils disparaître lorsque je mets les horodatages au format pts dans le conteneur? Je peux les extraire de mkv (mkvextract timecodes_v2 input.mkv 0: video.timecodes.txt 1: audio1.timecodes.txt 2: audio2.timecodes.txt 3: sub1.timecodes.txt 4: sub2.timecodes.txt 5: sub3 .timecodes.txt 6: sub4.timecodes.txt) mais uniquement au format timecodes_v2. Puis-je convertir timecodes_v2 en pts et les placer dans le conteneur pour éviter ces messages?
Meilleures salutations,
Félix
