  • FFmpeg not encoding with libx264 library

    29 octobre 2011, par bOkeifus

    Hey people of StackOverflow. I have been having a strange issue that I'm not exactly sure what's going on. I am using FFmpeg to convert any incoming video files to h264 mp4 files using the libx264. This is the log that I get from running this line of code :

    ffmpeg -y -i vdoname.flv -acodec libfaac -vcodec libx264 -sameq vid.mp4

    This is the log output after running the line :

Press [q] to stop encoding

    Can someone please help me out and tell me what to do to get this to work ? I guessed that the libx264 external library is not installed but it doesn't exactly say that in the log file and it looks as if it does find it but then doesn't actually encode the video.

    Any and all help is greatly appreciated.

    I've already tried installing unstripped-51 per a suggestion from a previous question but I am still unable to convert from .wav to .mp3
