Dears, I just installed kdenlive 20.04.01 on Kubuntu 20.04
My machine is a Lenovo ideapad 330S
When I try to make a proxy clip of any clip, 4K from my camera, or a youtube download, I get error mesage Failed to create proxy clip, with this log message
[Parsed_scale_vaapi_2 @ 0x561a7db88f40] Failed to create processing pipeline config: 12 (the requested VAProfile is not supported).
[Parsed_scale_vaapi_2 @ 0x561a7db88f40] Failed to configure output pad on Parsed_scale_vaapi_2
Error reinitializing filters!
Failed to inject frame into filter network: Input/output error
Error while processing the decoded data for stream #0:0
How to solve this ? Many thanks

I am having the same issue here!
Did you solve it?

I have this issue too. I'm using webp and mkv clips from youtube that have been cut with losslesscut.

I tried converting a clip to mp4 using ffmpeg, loading that into the project and trying to create a proxy clip. Same error.

I'm using Ubuntu 20.04 lts and Kdenlive 20.08.2 and ffmpeg version 4.2.4-1ubuntu0.1.

Thanks

I've had this problem too.

Changing the 'Encoding Profile' in the project's proxy settings worked. I changed it from 'Automatic' to 'x264' and have tried others too.

I had this problem too on Kdenlive Version 20.12.2 | Linux Mint 20.1 | Mesa Intel® UHD Graphics 630 (CML GT2)

Code: Select all

 sudo apt-get install intel-media-va-driver-non-free


solved this for me.

I'm having a similar error; "Failed to create proxy clip" with a default install of Kdenlive.

Here's the message itself:

[h264 @ 0x55603961b000] Failed setup for format vaapi_vld: hwaccel initialisation returned error.
Impossible to convert between the formats supported by the filter 'graph 1 input from stream 0:1' and the filter 'auto_scaler_0'
Error reinitializing filters!
Failed to inject frame into filter network: Function not implemented
Error while processing the decoded data for stream #0:1

It happens any time I attempt to generate proxies on a new or existing project.

Source media is standard long-GoP H.264 (in this case, meeting recordings from Zoom's backend.)
I'm able to edit it just fine without proxy encoding, it's just a bit jerky and laggy.

Likely, your machine is not compatible with the VA-API library and it can't create the processing pipeline config. You can try a few things:
Make sure you have the latest VA-API driver installed for your GPU
Try disabling VA-API in Kdenlive's settings and see if that resolves the issue
Try using another video encoding library such as x264 instead of VA-API
If you're running Kdenlive inside a virtual machine, try enabling GPU passthrough to make sure Kdenlive can access the host machine's GPU.
You can also try implementing the best isp proxies to try to solve this issue and make your connection safer.
