Yes I'm trying to avoid transcoding "on the fly". When I got a media wich requires transcoding, I re-encode it with VP9 codec wich is the most compatible and efficient (quality/bitrate ratio) but requires LOOOOOT of time ! Are you saying there is a case now where it transcodes when it could otherwise direct play a different version? Link to comment Share on other sites More sharing options...

Yes. Sometimes especially when I'm on WAN, If I have 2 versions : h264 8Mbps and vp9 2Mbps, the selected version is h264 and if the auto-quality determined a bandwith aroud 3 Mbps, there's a transcoding of the h264 version even if the vp9 one would play without transcoding. I hope I'm clear. Edited October 5, 2021 by elpoolet Link to comment Share on other sites More sharing options...

elpoolet 20 Posted October 6, 2021 Share Posted October 6, 2021 Yes it's in the WebApp. The VP9 file is 1.6GB large, h264 4.5GB So I uploaded it to SwissTransfer. Here are the links : VP9 : https://www.swisstransfer.com/d/028fab7c-64d6-463a-8307-23060da19cae h264 : https://www.transfernow.net/dl/20211006beU5GAj2 Link to comment Share on other sites More sharing options...

OK we'd have to look at the ffmpeg log because I tested and it worked as expected. I set the quality setting to 3 mbps, and it picked the vp9 file.

elpoolet 20 Posted October 8, 2021 Share Posted October 8, 2021 Hi @Luke Thanks for you answer. I encoded the video with VP9 at 1Mbps, and then it picked the vp9 file when playing and the bandwidth is at 2Mbps. Thanks Link to comment Share on other sites More sharing options...
