trim not recognizing crf option in ffmpeg #60

Closed isrealityreallyreal closed 2 years ago

[Disclaimer: I see that there are several open issues related to trim right now. At first glance my issue appears unrelated to any of those, though I may be mistaken.]

When I try to trim a line using ffmpeg it fails with the following output:

Encoding error:

Unrecognized option '-crf'.
Error splitting the argument list: Option not found
If there is no log before this, your encoder is not a working executable or your encoding command is invalid.

I looked up the unrecognized option '-crf' part, which led me to this answer suggesting that the problem derives from ffmpeg not being compiled with the --enable-gpl and --enable-libx264 options, but as you can see in the above output, it does include those options, so I'm not sure what's going on here.

I am using the typesetting tools fork of Aegisub, commit 9266-master-f21d8a360 if the title bar is to be believed. I installed Aegisub-Motion through Dependency Control. Looks like it's at version 1.0.9.

Any help is appreciated.

It's also worth noting that when I use ffmpeg outside of Aegisub, the -crf option works fine.

So... the issue went away when I went to Trim Settings and changed the encoder from x264 to ffmpeg. I could have sworn I had already done that when first prompted but maybe it didn't save the setting properly.

Previously, Aegisub had crashed when I clicked the Encoder button (in Trim Settings), so I had already hard coded the path to the ffmpeg executable in aegisub-motion.json prior to attempting any trim. Considering that the Encoder was actually set to x264 but with the path to ffmpeg, I understand why something went wrong, but it still baffles me how this could produce the error message I got.

Since this is no longer affecting me, I'll go ahead and close the issue.
