• unable ti decode video using h264_cuvid

  1er novembre 2017, par aymen

  I am using nvidia GTX 1080Ti, Driver Version : 387.12 .

  I am using the below command :

  ffmpeg -c:v h264_cuvid -i http://stream:port/channel output.mkv 

  And getting the following output :

• a command in a script doesn't work when the script is launched by cron

  5 mai 2023, par a k

  When I launch the script manually both as a not-root user (with sudo) and as the root, everything work correctly.
When Cron (Cron of the root) launches it, ffmpeg doesn't work (but the others lines of the script work correctly).

  


  #!/bin/bash
log=/var/log/log2/log2.txt

echo -n pwd '            ' >> "$log" ; pwd >> "$log"

  The script puts in the file /var/log/log2/log2.txt :

  I have tried to verify :

  


  

  • the permissions of the file ffmpeg

  


  • the permissions of the folder where ffmpeg writes to

  


  • the $PATH

  


  • the path of ffmpeg

  


  • the path of the file where ffmpeg should write to

  


  


• Linux C Makefile (FFmpeg) undefined reference to `curl_easy_init'

  23 juillet 2015, par hoschi111

  I did some changes to /libavformat/concat.c in the FFmpeg source.
  There I included libcurl.

  Internet says I have to add the following code to ’Makefile’.

  INCLUDE = -I/usr/local/include
  
  LDFLAGS = -L/usr/local/lib
  
  LDLIBS = -lcurl

  That did not work.
  I use this to build FFmpeg :

  make clean && ./configure --prefix=/usr --enable-gpl --enable-libmp3lame --enable-libx264 && make -j 4

  Error :

  /usr/lib/gcc/x86_64-linux-gnu/4.9/../../../../lib/libavformat.a(concat.o): In function `concat_read':
  
  /root/ffmpeg_sources/ffmpeg/libavformat/concat.c:151: undefined reference to `curl_easy_init'

  original Makefile :
  https://github.com/FFmpeg/FFmpeg/blob/master/Makefile

  Can you help me ?
