Codec HEVC/h.265 #17

Closed yann29800 closed 2 years ago

yann29800 commented 2 years ago

Bonjour, L'intégration du codec h.265 est elle présente dans votre package ffmpeg actuel pour Synology? Merci Yannick

th0ma7 commented 2 years ago

Pour la toutes les architectures sur DSM6 et DSM7 oui

yann29800 commented 2 years ago

Etrange. Lorsque je fais un ffmpeg -encoders je n'ai pas libx265 dans la liste. D'ailleurs un ffmpeg -h encoder=hevc retourne ceci : Codec 'hevc' is known to FFmpeg, but no encoders for it are available. FFmpeg might need to be recompiled with additional external libraries.

J'ai présumé x265 vs svt-hevc. svt-hevc est uniquement présent sous architecture x64 par contre x265 est disponible pour toutes les archtectures. Cependant ton NAS vient avec un ffmpeg par défaut fourni par Synology. Si tu veux utiliser le ffmpeg de SynoCommunity et non pas celui par défaut tu dois utiliser son chemin complet:
