 |
|
Hi all. I've spend all evening trying to read up on use flags and the like and am none the wiser on how to go about fixing this.
I guess a little hand holding is required - sorry.
I have emerged media-video.ffmpeg-1.0.7 and while it runs the following command successful
| Code: | | ffmpeg -n -threads 0 -i "$1" -acodec copy -vcodec copy -pix_fmt yuv420p -f mov "${1%%.*}.mov" |
I get a 'Unknown encoder 'libx264' error when trying
| Code: | | ffmpeg -n -threads 0 -i "$1" -s 320x180 -r 30000/1001 -b:v 200k -bt 240k -vcodec libx264 -acodec libfaac -ac 2 -ar 48000 -ab 192k "${1%%.*}.mp4" |
First I tried 'emerge libx264 but that doesn't exist.
Looking further the output of ffmpeg -codecs is
| Code: | D.V.LS h264 H.264 / AVC / MPEG-4 AVC / MPEG-4 part 10
|
So I'm guessing the libx264 codec is not installed.
But if libx264 isn't a package I can't see how to resolve this and reading google hits doesn't make it clear what I should do.
Can anyone offer a a light at the end of the tunnel, please? |

I tried putting
| Code: | | media-video/ffmpeg-1.0.7 libx264 |
but it gives an 'invalid atom' error |

Teegrins, nooster!
The actual issue was likely addressed already, but in case you did not figure out the following part, I'd like to say a thing or few about that.

The reason for this is that the format is incorrect, or rather incomplete, and thus rendered invalid (see man portage for more). Whenever you specify a version, you will need to also define if you want only the exact version, the version equal to and greater than... less or greater than... like so:
| Code: | =media-video/ffmpeg-1.0.7 x264
>=media-video/ffmpeg-1.0.7 x264 |
And so on and forth.
Considering it is a package that will likely be used for a while to come, one might omit the version altogether, and define the category/package alone:
| Code: | | media-video/ffmpeg x264 |
Or, enable the flag globally. ^^
I hope this helps~
