martos Posted October 26, 2019 Author Share Posted October 26, 2019 just for information, in dmesg repeat when i made my test : [29560.295075] meson-dw-hdmi c883a000.hdmi-tx: channels=2 sample_width=16 sample_rate=44100 [29560.295134] meson_aiu_i2s_dma_hw_params: physical_width=16 buffer_bytes=17664 period_bytes=4352 [29582.217953] meson-aiu-i2s meson-aiu-i2s.4.auto: Failed to set sysclk to 0Hz and i think i have trouble with the sound ( horrible ) Link to comment Share on other sites More sharing options...
martos Posted October 26, 2019 Author Share Posted October 26, 2019 if i understand this : https://www.phoronix.com/scan.php?page=news_item&px=Amlogic-H264-Decode-Almost https://lkml.org/lkml/2019/10/7/692 https://kodi.tv/article/devcon-2019-belgrade-part-iii we have this in the kernel 5.5 ... But now how it's made in LE ? Link to comment Share on other sites More sharing options...
