  • GStreamer x264enc not found

    5 avril 2017, par Dominik Schreiber

    I installed GStreamer-0.10 and all modules (base, good, bad, ugly, ffmpeg) according to these instructions (browse through by clicking prev/next) :
    http://www.linuxfromscratch.org/blfs/view/svn/multimedia/gst-plugins-ugly.html

    Everything seemed to have worked just fine but when I want to execute my pipeline I got this error :

    glib.GError: no element "x264enc"

    Apparently the module was not installed :

    gst-inspect x264enc
    
No such element or plugin 'x264enc'

    After that I installed the codec by executing :

    sudo apt-get install x264

    This did not work either. So I installed the latest build manually :
    http://www.videolan.org/developers/x264.html

    After a successful installation of x264 I ran ./configure on the gstreamer-0.10 ugly modules once again and found out about this :

    configure: *** checking feature: x264 plug-in ***
    
configure: *** for plug-ins: x264 ***
    
checking for X264... no
    
configure: No package 'x264' found
    
configure: *** These plugins will not be built: x264
    
configure: creating ./config.status

    A check if x264 is available seems to get fullfilled :

    which x264
    
/usr/local/bin/x264

    I’m using ubuntu server 12.04 LTS. Any ideas what I have to do to compile this module properly ? Thanks !

  • FFMPEG conversion from .H264 to MP4 playing too fast

    28 juin 2017, par NickR

    I accidentally deleted a video file but managed to save it with a recovery tool. The video was however corrupted, but I managed to repair that and now have a .h264 file.

    The file plays ok in the VLC player. There are a few glitches but on the whole its 98% perfect. However I now need to convert that into a more useable format (mp4 say).

    Ive downloaded the FFMPEG tool and have managed to pretty easily copy into mp4 with the following command line instruction :

    ffmpeg -i repairedVid.h264 -c copy repairedVid.mp4

    The problem is that the video is playing much too fast. I’ve done some research tried some tweaks that seem to have worked for other people (like forcing frame rate and changing the -vsync) :

    ffmpeg -i repairedVid.h264 -c copy repairedVid.mp4 -vsync 2 -r 23.976

    Ive also tried the crude approach of slowing the video down like this, but this was more of a long shot and I don’t think is the right way to go about it

    ffmpeg -i repairedVid.mp4 -filter:v "setpts=1.5*PTS" repairedVid.mp4

    This is the output when the video copies to MP4. Looks like it might have a clue to the problem (the video should be much longer than 4:40 minutes) :

    frame=13459 fps=1118 q=-1.0 size= 4102773kB time=00:04:40.65 bitrate=119756.4kbiframe=13459 fps=1117 q=-1.0 Lsize= 4102928kB time=00:04:40.65 bitrate=119761.0kbits/s speed=23.3x
    video:4102773kB audio:0kB subtitle:0kB other streams:0kB global headers:0kB muxing overhead : 0.003784%

    I’m totally new to FFMPEG and not having much luck. Any advice would be great.

    Thanks in advance
