Về: Enable h264 and mpeg4 encoder in ubuntu

[Thành Trung Nguyễn]

Well, I found that in gst-ffmpeg, we have ffenc_libx264 as h264 encoder. Enable libx264 when building gst-ffmpeg and I have it, but I can't make it work by this error:

(gst-inspect-0.10:30074): GStreamer-WARNING **: Failed to load plugin '/usr/lib/gstreamer-0.10/libgstffmpeg.so': /usr/lib/gstreamer-0.10/libgstffmpeg.so:undefined symbol: x264_encoder_encode

Is there any 1 have the idea on how to fix it ?

Thanks and best regards.

Hello,

May be this's not right place to ask this question. But it'll be great if any one can help.

Here's my problem: I need a program to encode video using h264 and mpeg4 codec in gstreamer, but seem gstreamer in ubuntu lacks of these encoder. I've searched google, tried some packages and tried to build the package from source code, too. With gst-ffmpeg source code, mpeg4 encoder is enabled by default but not h264, and although I tried some parameters to enabled h264 encoder, but all failed. So, is there any 1 know already built package(s) with these encoder or how to enabled h264 encoder to build it from gst-ffmpeg source code ?

Thanks and best regards.

You need to install x264 first.

Well, I think I have libx264 and libx264-dev installed already. By the way, I'm using ubuntu 9.04.

Thanks and best regards.

Ok, I found the solution for ffenc_libx264 in ubuntu 9.04.

Just install libavcodec-unstripped and it'll be there, no need to build gst-ffmpeg from source :D

Thanks and best regards.
