Code: Select all

“[webm @ 0000000009d4b200] Using AVStream.codec to pass codec parameters to muxers is deprecated, use AVStream.codecpar instead. [webm @ 0000000009d4b200] Using AVStream.codec to pass codec parameters to muxers is deprecated, use AVStream.codecpar instead. Current Frame: 2, percentage: 0”

Why is AVStream.codec depracated??

Use AVStream.codecpar instead? But how exactly? It does not tell me at all. It shows me no instructions how to use codecpar instead. It just yells at me.

Why could AVStream.codec not keep supporting passing codec parameters to muxers? Is it technically not possible to keep supporting both ways?

And most improtantly: How do I fix this problem?

Hello,
This warning comes from libavcodec encoder library, warning MLT library about code calling obsolete data format.
I proposed a patch to MLT few month back, but I was asked to rework it as it breaked compatibility with very old FFmpeg versions (<2) that they still want to support.
Sorry but for the moment we must just ignore it, this is not the cause of your failure.
Rendering stops at frame 2 (!), what is there at that position? (source clip format, effect/transition)
You seem very unlucky in your tests, thanks for keeping trying

Thank you for your post.

At frame 2, there is probably an unusual font that caused crashing, so I used a PNG picture as substitute.
I deliberately started rendering at what causes the error.

But I have a very long video project.

What can I do right now to get rid of that problem?
I will let the video rendering overnight, so I do not mind if it takes multiple hours.
