First download Mp3lame Engineering code,, why here to appear redundant talk about Mp3lame, is this. You will find that we did not specify the prefix in the./configure-prefix=/usr, it is clear that libx264.so and libx264.a will be copied to/usr/local/lib, remember here, and so on, because there are some changes to make.Ībove said H264, believe that mp3lame understanding is much simpler.ġ.

Execute./configure-enable-shared-enable-static on the line. A, so it's common to focus on shared and static keywords. Go to the x264 directory, and then./configure-help Look at its help information, what we need here is x264 to support ffmpeg in the form of. Download the x264 Project code First, 'Git clone git:///x264.git'.Ģ. There are lots of blocks here, such as/* Video codecs */,/* audio codecs */,/* external libraries * *īut you are in/* Video codecs */this piece but can not see H264 register_endecoder (H264, h264) This sentence, if you insist on the upside down, you will be in/* External libraries * * This piece found Register_encoder (LIBX264, libx264) So FFmpeg has an interface ready for H264, but requires a third-party library to support it.ġ. For whatever reason, FFmpeg does not have native support H264, but you can check avcodec_register_all this API, you will find a large register_encoder (xxx, XXX) A to/usr/local/)ĭo a search of FFmpeg's engineering code base, you will find each codec have a few member variables, but there are several codec missing encoder,h264 is one of them. Generally through the./configure-help command to query), ②, 'make' (compile), ③, 'Sudo made Install' (copy the generated binary application files and.

Literacy, Linux installation of a formal software, is generally the trilogy, ①, './configure' (add some possible parameters, such as enable some features, disable some features, what can be turned on and off. Now all you need is to install the other encoder on the line, essentially the other encoder in the form of a library installation, for example, the correct libx264.so or libx264.a stored under the/usr/lib under Or/usr/local/lib.įor two examples, the video encoder takes H264 For example, the audio aspect takes MP3 (mp3lame). Keywords: ffmpeg, code H264, third party encoderĪfter installing the FFmpeg, if you use the FFmpeg tool to turn a video file into H264 video encoding, MP3 audio encoding or other ffmpeg itself without the XXX encoding type, you will see the error message, unknown encoder ' xxx '.
