[FFmpeg-user] how to rename libx264 shared library(libx264.so.152) in FFmpeg

[Anand Veerappan]

Hi

Thanks for taking initiative and guiding us.

Please find our findings for your query.

- *Where is your libx264.so located?*
*Ans: The library path is the same folder where ffmpeg binary is located*

- *Please show us the output of*


*  objdump -p /usr/lib/libx264.so.152 | grep SONAME- Please show us the
output of  objdump -p /usr/lib/libx264-mv.so.152 | grep SONAME*
*Ans: Though we renamed libx264-mv.so.152 but it is
referring libx264.so.152 only*
*Refer below mentioned obj dump. *

Kindly guide us where to make changes to use modified libx264-mv.so.152 in
ffmpeg binary.

Regards
