Codec conversion

Postby crb001 » 04 Jun 2024 06:50

Converting an mp4/H.265 video file to mp4/H.264 results in, basicly, an empty file (only about 40KB).

Please open Tools -> Messages (set Verbosity to 2) before you start the conversion, keep the messages window open and then paste the full resulting log here or on Pastebin.com or on Justpaste.it if it's too long.

I see from the debug dialogue there is an error reporter: avcodec error: hardware acceleration picture allocation failed

Here is the entire message:

OneDrive ?
You'd better use a local file on your PC.

Thanks for pointing this out. This is a brand new machine, never thought Microsoft would configure the desktop as a OneDrive folder by default. Later today I will duplicate my problem and send you the resulting debut message.
