Ah yes the memory usage. I found that out when trying to burn in subtitles in a 4k HDR encode with AV1. I quickly ran out of memory as the encoding process was using 10 gigs! I thought I would be fine with 16gigs of ram, but it's obvious I need to double it at minimum. Now if only ECC ram didn't spike in cost..

What I find most weird of all is the amount of options listing a bunch of allowed values (0, 1, ... 9) and the default value -1 : yes, -1 (and no description). So, what is the encoder supposed to do with that particulat option set to -1 ??? |

The speed preset docs will then explain what the default values are per speed preset. |

Hi I am Rupesh and I converted large size MP4 avc x264 video files into av1 using ffmpeg and libaom and libopus successfully. The output file quality is acceptable to me but I can't play these videos in vlc media player especially in android smartphone and tablet
I can't play means when I fast forward to say 20 mins then video stops and audio plays. I heard that av1 codec has less support in many platforms but it will be supported in future. Can you suggest how to play these videos in android using vlc or any other player. |
