  • Compile ffmpeg for linux with mp3

    17 septembre 2011, par user916350

    I need compiled executable ffmpeg for my web-service on php. I downloaded source from author's site, and created executable file, but this file doesn't consist mp3 library (I need it). I read that I need download library from repository, but I think that I can't do that on hosting. Why can I create executable file with mp3 codec for easy copying ffmpeg on server ?

  • Is there any ffmpeg command which could process on bytes [on hold]

    18 juillet 2017, par IPS

    I have built RTSP service using c# code and it is useful to record videos using ffmpeg commands.

    My confusion is i’m getting bytes data in my response not sure whether it has frames and packets.

    So is there any way to pass bytes data into ffmpeg command to record video ?

  • aarch64 : Make transpose_4x4H do a regular transpose

    aarch64 : Make transpose_4x4H do a regular transpose

    Previously, ff_h264_idct_add_neon (originally in the arm version) used
    
a non-regular transpose in order to be able to use more instructions
    
that deal with registers as 128 bit register pairs. The aarch64
    
translation doesn’t do it to the same extent, but brought along the
    
same structure since it was a straight translation.
    

    This reshuffles ff_h264_idct_add_neon, bringing it closer to
    
the C implementation, making the transpose_4x4H macro do a regular
    
transpose, usable for other algorithms as well.
    

    Previously, the third and fourth output from transpose_4x4H were
    
swapped, and prior to cc29d96d5a, the same inputs as well. In
    
addition to just swapping the outputs, also renumber the intermediate
    
registers for better readability (making the register order match
    
transpose_4x8B).
    

    This runs with the same number of cycles as before.
