  • Ffmpeg not fully functioning

    26 août 2014, par Joshua

    Hello i have problem with ffmpeg i’m using phpvibe cms already asked in their forums but they don’t know the answer which leads me that it’s probably my fault so the problem is when i upload :

    6 seconds avi video which weights 817 KB it uploads perfectlly plays like it should run.

    However when i try upload 12mb avi sample i see that it does not work in folder where should be that video converted it shows 0kb size

    That means it didn’t start converting somewhow i think this is ffmpeg issue also i have spoted that my ffmpeg is placed in /usr/local/bin/ and in phpvibe cms systems there is different location for ffmpeg it looks like this : Img link

    Why when i upload small avi video it converts good and when i try longer it fails maybe it converts while upload process is going on but than why it shows 0b in folder where converted videos should be placed ?

    P.s i tried couple avi videos that weights more than 10 mb same thing and my code for ffmpeg conversation is :

    $output ="{ffmpeg-cmd} -i {input} -vcodec libx264 -s {ffmpeg-vsize} -threads 4 -movflags faststart {output}.mp4";

    Also tried :

    output ="{ffmpeg-cmd} -i {input} -vcodec libx264 -s {ffmpeg-vsize} -threads 4 {output}.mp4 2>&1";

    Same thing + im using Debian 7 Wheezy. Thanks !

    EDIT :

    i have made a test script it gives this output :

  • AAC encoder : Extensive improvements

    11 octobre 2015, par Claudio Freire
    AAC encoder : Extensive improvements

    This finalizes merging of the work in the patches in ticket #2686.
    

    Improvements to twoloop and RC logic are extensive.
    

    The non-exhaustive list of twoloop improvments includes :
    
 - Tweaks to distortion limits on the RD optimization phase of twoloop
    
 - Deeper search in twoloop
    
 - PNS information marking to let twoloop decide when to use it
    
   (turned out having the decision made separately wasn’t working)
    
 - Tonal band detection and priorization
    
 - Better band energy conservation rules
    
 - Strict hole avoidance
    

    For rate control :
    
 - Use psymodel’s bit allocation to allow proper use of the bit
    
   reservoir. Don’t work against the bit reservoir by moving lambda
    
   in the opposite direction when psymodel decides to allocate more/less
    
   bits to a frame.
    
 - Retry the encode if the effective rate lies outside a reasonable
    
   margin of psymodel’s allocation or the selected ABR.
    
 - Log average lambda at the end. Useful info for everyone, but especially
    
   for tuning of the various encoder constants that relate to lambda
    
   feedback.
    

    Psy :
    
 - Do not apply lowpass with a FIR filter, instead just let the coder
    
   zero bands above the cutoff. The FIR filter induces group delay,
    
   and while zeroing bands causes ripple, it’s lost in the quantization
    
   noise.
    
 - Experimental VBR bit allocation code
    
 - Tweak automatic lowpass filter threshold to maximize audio bandwidth
    
   at all bitrates while still providing acceptable, stable quality.
    

    I/S :
    
 - Phase decision fixes. Unrelated to #2686, but the bugs only surfaced
    
   when the merge was finalized. Measure I/S band energy accounting for
    
   phase, and prevent I/S and M/S from being applied both.
    

    PNS :
    
 - Avoid marking short bands with PNS when they’re part of a window
    
   group in which there’s a large variation of energy from one window
    
   to the next. PNS can’t preserve those and the effect is extremely
    
   noticeable.
    

    M/S :
    
 - Implement BMLD protection similar to the specified in
    
   ISO-IEC/13818:7-2003, Appendix C Section 6.1. Since M/S decision
    
   doesn’t conform to section 6.1, a different method had to be
    
   implemented, but should provide equivalent protection.
    
 - Move the decision logic closer to the method specified in
    
   ISO-IEC/13818:7-2003, Appendix C Section 6.1. Specifically,
    
   make sure M/S needs less bits than dual stereo.
    
 - Don’t apply M/S in bands that are using I/S
    

    Now, this of course needed adjustments in the compare targets and
    
fuzz factors of the AAC encoder’s fate tests, but if wondering why
    
the targets go up (more distortion), consider the previous coder
    
was using too many bits on LF content (far more than required by
    
psy), and thus those signals will now be more distorted, not less.
    

    The extra distortion isn’t audible though, I carried extensive
    
ABX testing to make sure.
    

    A very similar patch was also extensively tested by Kamendo2 in
    
the context of #2686.

  • Could not find tag for codec h264 in stream #2 when trim video and add watermark, music background

    I'm doing cut video into chunks, then join them and add watermark and background music with the command below.
