  • Failed to compile x264 library for android, error description : clang:error no such file or directory

    12 janvier 2019, par Lee.Saipeng

    I use a shell script to compile the x264 library to the android platform, the architecture is armeabi-v7a,The x264 library was cloned from github。

    I am sure I have those directories,and I checked the search engine such as google,No one encountered the same situation

make clean
make STRIP= -j8 install || exit 1

cp -f $PREFIX/libx264.a $PREFIX

    The error is here enter image description here The result is that this x264 library cannot be used. Can someone help me? thanks very much

    Ok, I generated the config.log file during the compilation of x264, I hope it is an error log file, the log content is as follows:

  • How to access YUV planes from ratecontrol in x264 encoder

    31 décembre 2018, par shuch

    I need to get access to the YUV planes in x264 encoder on the encoding stage. I understand how to do it on the input stage (in raw.c), but I don't succeed to do it in encoder.c or ratecontrol.c.

    Thanks

  • Why x264 takes 100% CPU usage when watching video ? [on hold]

  • Changing x264 settings on the fly

    22 décembre 2018, par S Red

    I am curious to know if anyone has experience with modifying x264 settings during encoding (this is for testing live streaming hence I need to be able to modify settings based on cpu and upload characteristics).

    I saw an API for encoder_reconfig() in x264.h, curious if folks have used that, and if its accessible from ffmpeg? Is it possible to modify a high-level option like 'preset', or do I need to modify individual options like chroma-me, trellis etc.

  • FFMPEG - MP4 won't play in FireFox - file corrupt

    21 décembre 2018, par fightstarr20

    I am encoding MP4 file using FFMPEG with the following command...

    ffmpeg -ignore_chapters 1 -i video.mov -c:v libx264 -preset veryslow -crf 23 -an -r 24 -s 1280x720 video.mp4

    The resulting MP4 file plays correctly in Chrome, but in Safari and FireFox I get nothing. FireFox tells me the file is corrupt and can't be played.

    Where am I going wrong?
