• Batch file to perform multiple conversions in a row

  16 septembre 2020, par ben158

  I'm trying to write a batch file that can be launched from Handbrake GUI with the "send file to" feature, that will split an MKV into chapters with MKVmerge, then convert all those new files into mp4s with ffmpeg. Handbrake passes only one argument into the batch file, the full file path of the output (surrounded by quotes). I'm very new to batch scripting and am having difficulty getting it all to work together — all the individual parts work just fine when absolute paths are given. Here's the content of the .bat file :

  


  START /WAIT "C:\Program Files\MKVToolNix\mkvmerge.exe -o output.mkv --split chapters:all %1"
for %%i in (*.mkv) do C:\ffmpeg\bin\ffmpeg.exe -i "%%i" -loop 1 -i "%%~dpi"\folder.jpg -map 1:v -map 0:a -c:a ac3 -b:a 640K -pix_fmt yuv420p -c:v libx264 -shortest -fflags +shortest -max_interleave_delta 100M "%%~ni.mp4"


  


  Any glaring mistakes I'm making ? I've been at this for hours reading SO threads and documentation, and can't figure it out for the life of me. Any help is appreciated, thanks in advance.

  


• FFMPEG x265.so.79 lib

  4 mai 2017, par Teemo

  Trying to make some pictured from video with ffmpeg with this command :

  ffmpeg -i input.mp4 -ss 01:23:45 -vframes 1 output.jpg

  but constantly getting this error :

  ffmpeg: error while loading shared libraries: libx265.so.79: cannot open shared object file: No such file or directory

  when i execute :

  ldd $(which ffmpeg) 

  i get this output :

  linux-vdso.so.1 =>  (0x00007fff8417f000)
  
  libdl.so.2 => /lib/x86_64-linux-gnu/libdl.so.2 (0x00007f74c7130000)
  
  libm.so.6 => /lib/x86_64-linux-gnu/libm.so.6 (0x00007f74c6e27000)
  
  libpthread.so.0 => /lib/x86_64-linux-gnu/libpthread.so.0 (0x00007f74c6c09000)
  
  libc.so.6 => /lib/x86_64-linux-gnu/libc.so.6 (0x00007f74c6840000)
  
  /lib64/ld-linux-x86-64.so.2 (0x0000558ae35d3000)

  After wasting multiple hours and trying to install modules and libraries to get through dependency hell still no progress, always getting that error.

  Using Ubuntu 16.04.

  I am desperate, so any help would be appreciated

• compiling FFmpeg on AIX

  3 mars 2017, par epitaxial

  I’m a hardware guy that likes to play around with different architectures and operating systems. Anyhow I’m trying to compile FFmpeg on AIX 7.1 using gcc but having some issues. I grabbed the latest code from git and while it does compile with a few warnings FFmpeg does not work. From my limited understanding it looks like the code is using 64 bit integers but was compiled as 32 bit ? Maybe someone can shed some light on this. Here is what happens when executing FFmpeg

  ./ffmpeg -i rtsp://192.168.1.9:554 -an -c copy -t 1:00:00 test.mp4

  rtsp://192.168.1.9:554: Can't assign requested address

  Is my reasoning correct ? Thanks.
