  • Debian killing ffmpeg

    3 juillet 2017, par Viktor Joras

    It must be some kind of Linux update because all of a sudden, after years of ffmpeg usage with Debian, ffmpeg gets killed without a logic reason. The funny part is there is no trace of killings in log files inside /var/log. Nothing !

    The killings are more or less random, sometimes it happens after 1 second, other times after 50 seconds.

    While transcoding ffmpegs outputs "Killed" and after few rows it outputs "Exiting normally, received signal 15".

    The same behaviour happens with 4 different machines with Debian, kernel 3.16 and 4.9 with a lot of RAM, so memory is not the issue.

    Is there a kind of setting that limits CPU or some other devilry that is ruining my happiness ?

  • bash script to install / update ffmpeg static builds

    1er mars 2017, par Joakim

    Hi I’m trying to make my first "real" bash script to do some real work than can be executed both manually and through cron jobs.

    The script should download and install the ffmpeg-static-build from https://johnvansickle.com/ffmpeg

    Here is what I’ve got so far :

    #!/bin/bash
    # Still to come, see if the script runs with root privileges else exit
    #Download FFMPEG static daily build and it's md5
    cd ~
    wget https://johnvansickle.com/ffmpeg/builds/ffmpeg-git-64bit-static.tar.xz | tar -xf
    #wget https://johnvansickle.com/ffmpeg/builds/ffmpeg-git-64bit-static.tar.xz.md5
    curl -L https://johnvansickle.com/ffmpeg/builds/ffmpeg-git-64bit-static.tar.xz.md5 | tar -xf | tee -a https://johnvansickle.com/ffmpeg/builds/ffmpeg-git-64bit-static.tar.xz | cut -d\  -f1 | md5sum > md5sum.txt


    #Chech the md5 is currect
    #md5sum -c MD5SUMS
    file1="md5sum.txt"
    file2="ffmpeg-git-64bit-static.tar.xz.md5"

    if ! cmp --silent "$file1" "$file2"; then
       echo "md5sum doesn't match...\n exit" >&2
       exit 1
    fi


    #tar -xf ffmpeg-*.tar.xz
    cp ffmpeg-*-static/ff* /usr/bin/
    cp ffmpeg-*-static/ff* /usr/local/bin/
    cp ffmpeg-*-static/qt-faststart /usr/bin/
    cp ffmpeg-*-static/qt-faststart /usr/local/bin/
    # Consider change second location to use ln -s
    # Remove downloads and do some clean up

    rm -fr ffmpeg-*

    #EOF

    As you can see in the script i would like to add the md5sum check but it fails (got the md5sum check part from Compare md5 sums in bash script)

    If i remove the md5sum part the script is working, but right now the script fails at the | tar -xf | part with this code

    As this is my first, I would appreciate any "I’m 4 years old" advices and why

    update

    Have made some changes to the script based on the suggestions in this thread, but my problem is I have no output what so ever at this state :( So I think it’s time to ask for the next clue

    ##
    ## To make this script working you might need to change the below values

    ## to obtain the right links you have to have a look @ https://johnvansickle.com/ffmpeg/
    ## and then change those below
    ##
    ## If you are running on a shared server or dowsn't have root priviliges you might need to uncomment
    ## point 5.

    note : do to some more in depth answering of why not compile from source :
    1. This precompiled is usable on all Linux variations, despite distro and version
    2. It usable on shared hosting servers with ssh access

    But still having some issues :(

    1. Running this script returns : a blanc shell, but I’ve expected one of the printf statements
    2. When I’m trying to narrow down the problem and going back to basic and trying to run the script with only the "if" part it fails with 44 : Syntax error : "(" unexpected
    3. running the very same "if" part typed directly into the shell/terminal itself it’s all happy !!

  • Announcing TMPGEnc 4 : now with x264 !

    26 novembre 2010, par Dark Shikari — commercial, japan, licensing, x264

    A few months ago, we announced a commercial licensing program so that even companies unable to use GPL software in their products have a chance to use the open source x264 instead of proprietary alternatives. The system worked on two basic concepts. First, all licensees would still be required to give their changes to x264 back to us : x264 must forever remain free, with no useful contributions kept hidden from the community. Second, all the profits would go directly back to x264, primarily to the developers who’ve made the most significant contributions to x264 over the years, but also to funding future development, bounties for new features, as well as contributing to other related projects (e.g. Videolan and ffmpeg).

    Over the past couple of months, we’ve gotten an enormous response ; over 40 companies have inquired about licensing, with more contacting us every day. Due to the sheer volume of interest, we’ve partnered with CoreCodec, the creators of the free Matroska container format and developers of CoreAVC, to make x264 as widely available as possible in the world of commercial software as it is in the world of open source. All of this is already filtering back to benefiting x264 users, with many bugs being reported by commercial licensees as well as some code contributed.

    Today, we announce the first commercial consumer encoding software to switch to x264 : Pegasys Inc.’s TMPGEnc. Expect many more to follow : with x264 now available commercially as well as freely, there are few excuses left to use any other H.264 encoder. Vendors of overpriced, underpowered proprietary competitors should begin looking for new jobs.
