[AWS VT1 EC2] ffmpeg: error while loading shared libraries: libavdevice.so.58

[tkamiya0831]

Hello Xilinx team,

I have tried an AWS VT1 instance and used the accelerated ffmpeg. It worked properly when I run it manually. Also I have created a .sh file to make it easier to use.

Then, I set the .sh file in the crontab but it did not work properly. I checked the cron log for this action, then I found the following error log.

ffmpeg: error while loading shared libraries: libavdevice.so.58: cannot open shared object file: No such file or directory

I searched the same error message then someboby said the following solution.

1) sudo find / -name libavdevice.so.58 Find the libavdevice.so.58. The location is the following. /opt/xilinx/ffmpeg/lib/libavdevice.so.58

2) Copy the libavdevice.so.58 to /etc/ld.so.conf.d/ I have copied the /opt/xilinx/ffmpeg/lib/libavdevice.so.58 to /etc/ld.so.conf.d/

3) Read the config sudo ldconfig

I have tried the above actions. However, it can not run with cron.

Would you tell me, how do I use the accelerated ffmpeg with cron?

Hello @tkamiya0831 . This appears to be an environment issue. Can you try to update the your shell script to include the environment PATH and LD_LIBRARY_PATH updates normally performed by our xcdr_setup.sh before attempting to run ffmpeg:

source /opt/xilinx/xrt/setup.sh
export LD_LIBRARY_PATH=/opt/xilinx/ffmpeg/lib:$LD_LIBRARY_PATH
export PATH=/opt/xilinx/ffmpeg/bin:/opt/xilinx/xcdr/bin:/opt/xilinx/launcher/bin:/opt/xilinx/jobSlotReservation/bin:$PATH

Hello @jmouroux. Thank you for your quick reply. I have tried to add your sentence into my shell script. It worked fine. Thank you for your cooperation.
