VLC záznam pracovní plochy vadný Libav/FFmpeg
« kdy: Červenec 04, 2020, 18:53:17 »
V předchozí verzi Mageia 6.1 jsem používám VLC pro nahrávání pracovní plochy.
Teď ve verzi Mageia 7.1 se mi to nedaří zprovoznit.
VLC píše:
Kód: [Vybrat]
avi info: stream[0] duration:0 totalsize:0 frames:0 fps:25,000000 KiB/s:128
avi info: stream[0] duration:8 totalsize:1783296000 frames:215 fps:24,991480 KiB/s:1619447
main info: playlist is empty
avcodec error: cannot find encoder MS MPEG-4 Video v1 *** Your Libav/FFmpeg installation is crippled. *** *** Please check with your Libav/FFmpeg packager. *** *** This is NOT a VLC media player issue. ***
stream_out_transcode error: cannot find video encoder (module:any fourcc:DIV1). Take a look few lines earlier to see possible reason.
stream_out_transcode error: cannot create video chain
main error: cannot create packetizer output (RV32)

podíval bych se na nastavení kodeků. Při přehrávání záznamu vidím jen
Kodek: 32bits RGB (RV32)

VLC ale nepoužívám, moc nevím kde se toto nastavuje. Můžu poskytnout moji konfiguraci. Nikdy jsem nic nenastavoval (mám nastavení distribuce).
cat /etc/mageia-release
Mageia release 8 (Cauldron) for x86_64
