  • When recording MP4 using ffmpeg suddenly power off

    2 décembre 2016, par wanglx

    Now I used C language and ffmpeg realize a multiplex real-time audio and video to MP4 files of the program and everything works fine, but when in the process of reuse of sudden power failure, the recording is MP4 file is damaged, VLC can not play this file.
    I think reason is no call to write the trailer function av_write_trailer , causing index and time stamp information lost, I use araxis merge tool compared the successful call av_write_trailer function of file and a no av_write_trailer to call the damaged files and found two different points :
    1. Damaged files in the file header box number value not right
    2. The damaged file no end of file.

    Now I want to repair after power on my program can automatically repair the damaged files, in Google did not find effective methods.
    my train of thought is in the normal recording process saves per second a damaged file is missing two information : box number and end of file, save it to a local file, when writing the MP4 file integrity delete this file after, if power off damaged, then in the next power, read the file and the corresponding information to write the damaged files corresponding position to. But now the problem is that I don’t know how to save the number of box and the end of the file, I this is feasible ? If possible, what should I do ? Looking forward to your reply !

  • avcodec/ppc/h264dsp : POWER LE support in h264_idct_dc_add_internal() fix vec_lvsl bug

    avcodec/ppc/h264dsp : POWER LE support in h264_idct_dc_add_internal() fix vec_lvsl bug

    We got defective video when use GCC 4.9.2 instead of GCC 4.9.1 to compile FFMEPG. And further found
    
that GCC 4.8 and 4.9 need patch to fix the lvsl/lvsr bug on POWER LE, and GCC 5.1 contains
    
the correct code since its release. The message on gcc-patches requesting approval for lvsl/lvsr
    
patch is at https://gcc.gnu.org/ml/gcc-patches/2014-10/msg00228.html.
    

    The fixed code avoids using lvsl and will not depends on GCC version, also it uses less instructions on POWER LE.
