This is also a regression from Digikam 5.9.0 in regular Debian. Selected audio codec: afm: ffmpeg (FFmpeg AAC (MPEG-2/MPEG-4 Audio)) Selected video codec: vfm: ffmpeg (FFmpeg HEVC / H.265) One of the videos is reported by mplayer like this: Within Digikam, however, the issue as I described above persists. Outside of Digikam, my system is quite capable of playback of both H.264 and H.265 video at 4K.
I switched to an Intel video-based system with HEVC decoding acceleration (necessary for 4K H.265 playback). I don't know if a missing nouveau_drv_video.so is the cause of this problem, but it might be a reasonable place to start. The nouveau_drv_video.so file used by vlc is in the Debian package mesa-va-drivers. There is significant skipping and jumping in the video playback. Since I have upgraded to the digikam flatpak, however, this 4K video cannot play smoothly. This also worked fine on the older version of Digikam included in buster. When playing on the host system with vlc, vlc comments "Trying to open /usr/lib/x86_64-linux-gnu/dri/nouveau_drv_video.so". I am using the Nouveau open-source nvidia drivers. This video plays back fine in my Debian buster system using VLC. (Not sure why 7.0.0 release or 7.1.0 isn't in flatpak).Īnyhow, I have a Pixel 2 XL and a Pixel 4a. I am running the latest Flatpak digikam, which identifies with version 7.0.0-rc in Flatpak, and in Help->About as 7.0.0 with a build date of Sept.
