I already searched quite a lot but it's really hard to find "realiable" information, so I decided to ask here:<br><br>- It seems that hw accel is not available in kdenlive <br><br>- As far as I understand kdenlive uses mlt which uses ffmpeg. ffpmeg can use hardware acceleration for de- and encoding. So is mlt to "blame" for missing hw accel. in kdenlive?<br><br>- There has been a patch (bug 378832) "use of vaapi in transcoding and rendering" which seems to tackle my question. But what did it really change -<br>/ what is it for? I didn't find more info on that and it's in kdenlive 17.04, while Debian is at 16.12. and before I compile myself I'd like to get more info.<br><br>- Furthermore I found a thread on this list back in April "kdenlive and mlt nvenc enabled" covering the same topic but for nvidia instead of Intel graphics; unfortunately nobody reported back if it really works. For me it reads like the patch I mentioned above.<br><br>So regarding the current state of hw accel in kdenlive I'm still uncertain.<br><br>Thank you for your inputs.<br><br>Kind regards<br>Bernd </p>
