transcode: can't encode using ffmpeg's h264

[Adrian Fita]

Binary package hint: transcode

When I try to encode a DVD with DVD:RIP by choosing ffmpeg/h264 in transcode I receive the following error:

I don't know if it's ffmpeg's ar transcode's fault, but ffmepg says that it has h264:

I'm using Ubuntu 8.04.1, transcode Version: 2:1.0.2-0.8ubuntu7.

Thank you.

FFmpeg does only have an h264 decoder, not an encoder. Encoding to h264
is only possible using x264 AFAIUI

transcode btw correctly notices that:

Nothing to fix here, as far as I see.

I was using DVD::RIP and it was working just fine some time ago (didn't use it for a while). It has ffmpeg/h264 in the video codecs selection, but I seem I can't use them.

Has anything happen lately with dvd:RIP/transcode/ffmpeg?

[Reinhard Tartler (siretart)]

not that I knew.

ffmpeg could in theory link against x264, but we cannot do so in ubuntu,
because x264 is in multiverse whereas ffmpeg is in main.

if ffmpeg could load x264 at runtime instead of at load time then we
could enable it. promoting x264 is a no-go, IMO.

Ok. I understand. So this is not a bug.

Well then, you can close the bug report. I managed to encode to h264 using acidrip/mencoder.

Status changed to 'Confirmed' because the bug affects multiple users.
