• How to quote a file name with a single quote in ffmpeg movie= filter notation ? [closed]

  21 avril, par PieterV

  I am trying to run ffmpeg using a file that contains a single quote ' in the filename.

  


  I tried to follow the docs that say I should replace a ' with '\''.
  
And a ticket that says I should replace a ' with \\\\\'.

  


  I've tried both, and can't get get it working.

  


  E.g. docs format :

  


  ./ffprobe -loglevel error -read_intervals %00:30 -select_streams s:0 -f lavfi -i "movie='D\:\\Test\\Interlaced - Dragons'\'' Den - S14E02 - Episode 2.mkv'[out0+subcc]" -show_packets -print_format json

{
[Parsed_movie_0 @ 00000222a2f82200] Failed to avformat_open_input 'D:\Test\Interlaced - Dragons Den - S14E02 - Episode 2.mkv'
[AVFilterGraph @ 00000222a2f76ec0] Error processing filtergraph: No such file or directory
movie='D\:\\Test\\Interlaced - Dragons'\'' Den - S14E02 - Episode 2.mkv'[out0+subcc]: No such file or directory


  


  E.g. ticket format :

  


  ./ffprobe -loglevel error -read_intervals %00:30 -select_streams s:0 -f lavfi -i "movie='D\:\\Test\\Interlaced - Dragons\\\\\' Den - S14E02 - Episode 2.mkv'[out0+subcc]" -show_packets -print_format json

{

  > dir "D:\Test\Interlaced - Dragons' Den - S14E02 - Episode 2.mkv"

  This is on Win11 using FFmpeg7.
  
Any ideas ?

  


  [Update]
  
I found a doc on escape filtergraph strings, did not help, I tried 0 to 7 \.

  


  I also found and tried the ffescape utility, the output it produces just uses a single \' and does not work.

  


  > echo "D:\Test\Interlaced - Dragons' Den - S14E02 - Episode 2.mkv" | ./ffescape.exe
=> D:\\Test\\Interlaced - Dragons\' Den - S14E02 - Episode 2.mkv\

> ./ffprobe -loglevel error -read_intervals %00:30 -select_streams s:0 -f lavfi -i "movie='D:\\Test\\Interlaced - Dragons\' Den - S14E02 - Episode 2.mkv\'[out0+subcc]" -show_packets -print_format json
{

movie='D:\\Test\\Interlaced - Dragons\' Den - S14E02 - Episode 2.mkv\'[out0+subcc]: No such file or directory


  


  [Update]
  
I found docs for ffmpeg filter script where I can place commands in a file.

  


  I tried ./ffprobe -loglevel error -read_intervals %00:01 -select_streams s:0 -f lavfi -/i "d:\filtergraph.txt" -show_packets -print_format json, and it load the script.

  


  Works : movie=test.mkv[out0+subcc]\ if test.mkv is in ffprobe dir.
Works : movie=test\'.mkv[out0+subcc]\ if test'.mkv is in ffprobe dir.
  
Not : movie=D:\test.mkv[out0+subcc]

Not : movie=test space.mkv[out0+subcc]

• cross compiling ffmpeg with conan fails : x86_64-w64-mingw32-ld : unrecognised emulation mode : 64

  6 février, par ovni jeroqui

  I'm trying to install ffmpeg (and some other libraries, but ffmpeg alone fails too) with conan to cross compile from linux (ubuntu) to windows.

  


  Conan throws an error on Running configure, inside build(). It says that x86_64-w64-mingw32-gcc is unable to create an executable file..

  


  On the config log I discovered it's because of a flag when running tests for x86_64-w64-mingw32-ld.

  


  x86_64-w64-mingw32-ld -m64 -L/home/jeroqui/.conan2/p/b/freetd8d522cfe5ed9/p/lib -L/home/jeroqui/.conan2/p/b/libsv9862cce477f3c/p/lib -L/home/jeroqui/.conan2/p/b/opensf32bb84148b27/p/lib -L/home/jeroqui/.conan2/p/b/vorbib2efb2d738443/p/lib -L/home/jeroqui/.conan2/p/b/libpn1c271e119251a/p/lib -L/home/jeroqui/.conan2/p/b/dav1d0798c06f2d7c3/p/lib -L/home/jeroqui/.conan2/p/b/libaoec0c6ff69236b/p/lib -L/home/jeroqui/.conan2/p/b/cpuin94c00ccfd6939/p/lib -L/home/jeroqui/.conan2/p/b/zlib09a824ccbeb0e/p/lib -L/home/jeroqui/.conan2/p/b/libwedcd84ab019a17/p/lib -L/home/jeroqui/.conan2/p/b/libfdbad6e447d67d4/p/lib -L/home/jeroqui/.conan2/p/b/libmpeb5a9a1a779c7/p/lib -L/home/jeroqui/.conan2/p/b/libvp0218afdff461c/p/lib -L/home/jeroqui/.conan2/p/b/libx2ec0d07d4a0565/p/lib -L/home/jeroqui/.conan2/p/b/libx23198ed0a549b9/p/lib -L/home/jeroqui/.conan2/p/b/opus8d5d63e1681f3/p/lib -L/home/jeroqui/.conan2/p/b/ogg813050272864b/p/lib -L/home/jeroqui/.conan2/p/b/openh3680a2c5cc945/p/lib -L/home/jeroqui/.conan2/p/b/openj09e5e15be595a/p/lib -L/home/jeroqui/.conan2/p/b/brotl58bc227a041f8/p/lib -L/home/jeroqui/.conan2/p/b/bzip2e67b6fd4c7720/p/lib -L/home/jeroqui/.conan2/p/b/libic229c7a1dc80e2/p/lib -L/home/jeroqui/.conan2/p/b/xz_ut8375de634122a/p/lib -m64 -o /tmp/ffconf.eAkkSIml/test.exe /tmp/ffconf.eAkkSIml/test.o

  I've tried to get conan to not add the -m64 flag, but I haven't been able to get it working. Setting env variables like LDFLAGS= doesn't seam to work either on the conan profile, on the conanfile.py or directly on my terminal. Any suggestions ?
