Feature support varies – for more complex codecs with many different profiles, hardware decoders rarely implement all of them (for example, hardware decoders tend not to implement anything beyond YUV 4:2:0 at 8-bit depth for H.264). Hardware decoders will generate equivalent output to software decoders, but may use less power and CPU to do so. On PC-like platforms, video hardware is typically integrated into a GPU (from AMD, Intel or NVIDIA), while on mobile SoC-type platforms it is generally an independent IP core (many different vendors). Using such hardware allows some operations like decoding, encoding or filtering to be completed faster or using less of other resources (particularly CPU), but may give different or inferior results, or impose additional restrictions which are not present when using software only. What should I do to make encode video in h.Many platforms offer access to dedicated hardware to perform a range of video-related tasks. Include the log file 'config.log' produced by configure as this will help If the latest version fails, report the problem to mailing list or IRC #ffmpeg on. If you think configure made a mistake, make sure you are using the latest configure -enable-gpl -enable-libx264 ERROR: libx264 not found How to quickly compile FFmpeg with libx264 (x264, H.264). I am using ffmpeg 3.0, from that list, it seems that encoding with h264 is not supported, only decoding h264 is supported, right? I checked the list of supported codec Codecs:

Here is my comannd: (I tried h264, x264, libx264, none of them worked) ffmpeg -i Fashion.divx -acodec aac -vcodec libx264 out.mp4 I have installed ffmpeg 3.0 from, I am trying to convert a video coded with mepeg4 part 2 to H264, but I got Unknown encoder 'libx264'
