• FFmpeg can't read a video stream, but VLC reads it fine

  21 mai 2022, par J.Doe

  I have a video stream that I can access using VLC, but can't access with ffmpeg. This used to work before I moved onto using a new computer (but with same camera).

  


  This is the ffprobe command (made up IP addr) :

  


  ffprobe -hide_banner -rtsp_transport tcp "rtsp://root:pass@12.34.567.890:80/axis-media/media.amp?event=on&eventtopic=onvif:VideoSource/MotionAlarm/."

  


  It returns

  


  rtsp://root:pass@12.34.567.890:80/axis-media/media.amp: Invalid data found when processing input


  


  I've not found very much on this problem :

  


  

  • I've tried turning it off and on again

  


  • I looked through this github issue but there were no solutions

  


  • I know it supports TCP since it's the same command as when it worked last time.

  


  


  Any ideas how I can get ffmpeg to read the stream ?

  


  Edit : Output of -report below, I'm afraid it's not very helpful :

• "Undefined referance to function" while linking ffmpeg [duplicate]

  19 mai 2022, par user19068953

  I'm trying to link ffmpeg on ubuntu, i downloaded ffmpeg source and added to my lib/ffmpeg library then ran ./configure, i created a cmake on my project directory and one inside ffmpeg dir. The cmake compiles just fine but when i run make it just gives me an error saying Undefined referance to avformat_alloc_context(), it says this for all functions but the structs, typedefs and defines compile just fine. Here are my files :

  


  ./cmake :

  


  cmake_minimum_required(VERSION 3.14)

set(CMAKE_CXX_STANDARD 14)
set(CMAKE_CXX_STANDARD_REQUIRED ON)
project(Interview C CXX)

add_definitions(-DGL_SILENCE_DEPRECATION)

# ffmpeg linking -----------------------------------------------


add_library(ffmpeg STATIC IMPORTED)
add_subdirectory(lib/ffmpeg)

target_include_directories(Interview PRIVATE ${CMAKE_CURRENT_SOURCE_DIR}/lib/ffmpeg)

link_directories(${CMAKE_SOURCE_DIR}/lib)

set(CMAKE_MODULE_PATH ${CMAKE_MODULE_PATH} "${CMAKE_SOURCE_DIR}/cmake/")


  


  The cmake files are a bit messy since i am trying to figure this out.
./lib/ffmpeg/cmake :

  


  cmake_minimum_required(VERSION 3.14)
project(ffmpeg)

list(APPEND SOURCES
    libavformat/avformat.h
    libavformat/avformat.c
)

file(GLOB_RECURSE SOURCE_FILES 
    ${CMAKE_SOURCE_DIR}/*/*.c
)   
# Add header files
file(GLOB_RECURSE HEADER_FILES 
    ${CMAKE_SOURCE_DIR}/*/*.h
)

include_directories(${CMAKE_SOURCE_DIR}/libavformat)
link_directories(${CMAKE_SOURCE_DIR}/libavformat)


  


  and my main file that i run my test src/main.cpp :

  


    extern "C"{&#xA;    #include <libavformat></libavformat>avformat.h>&#xA;}&#xA;&#xA;#include <iostream>&#xA;int main(int argc, char* argv[]) {&#xA;    AVFormatContext* context; &#xA;    context = avformat_alloc_context();&#xA;    std::cout &lt;&lt; context &lt;&lt; std::endl;&#xA;}&#xA;</iostream>

  


  Again, no problem when using type's like AVFormatContext and defines but when i use a function like avformat_alloc_context it gives of this error (the source files are inside ffmpeg, i can inspect them with ctrl right-click on VSCode) :

  


   /usr/bin/ld: CMakeFiles/Interview.dir/src/main.cpp.o: in function main': main.cpp: 
   (.text+0x4e): undefined reference to avformat_alloc_context' collect2: error: ld returned 1 
   exit status make[2]: *** [CMakeFiles/Interview.dir/build.make:84: bin/Interview] Error 1 
   make[1]: *** [CMakeFiles/Makefile2:96: CMakeFiles/Interview.dir/all] Error 2 make: *** 
   [Makefile:84: all] Error 2


  


  Edit :
I edited the cmake file but now im getting a different error :

  


  find_path(AVCODEC_INCLUDE_DIR NAMES "avformat.h" PATHS 
${CMAKE_CURRENT_SOURCE_DIR}/lib/ffmpeg/libavformat)
find_library(AVCODEC_LIBRARY avformat)

link_directories(${CMAKE_SOURCE_DIR}/lib)

add_executable(Interview src/main.cpp)

target_include_directories(Interview PRIVATE ${AVCODEC_INCLUDE_DIR})
target_link_libraries(Interview PRIVATE avformat)

add_library(ffmpeg STATIC IMPORTED)
add_subdirectory(lib/ffmpeg)

target_include_directories(Interview PRIVATE ${CMAKE_CURRENT_SOURCE_DIR}/lib/ffmpeg)

set(CMAKE_MODULE_PATH ${CMAKE_MODULE_PATH} "${CMAKE_SOURCE_DIR}/cmake/")


  


  Note : AVCODEC_LIBRARY returns notfound cmake error but just using avcodec in target_link_libraries somehow doesn't result in a cmake error, however when i run make like this it gives this error :

  


  usr/bin/ld: cannot find -lavformat collect2: error: ld returned 1 exit status make[2]: *** [CMakeFiles/Interview.dir/build.make:84: bin/Interview] Error 1 make[1]: *** [CMakeFiles/Makefile2:96: CMakeFiles/Interview.dir/all] Error 2 make: *** [Makefile:84: all] Error 2


  


• FFMPEG image capture only executes partially on cron

  17 mai 2022, par C. Ardayfio

  I have the following shell script :

  


  DailyScript.sh

  


  #!/bin/sh
now="/Users/mydir/Downloads/LIDOPRO/Captures/$(date +'%Y_%m_%d_%I_%M_%p').jpg"
"/Users/mydir/Downloads/LIDOPRO/ffmpeg" -ss 0.5 -f avfoundation -framerate 30 -i "0" -frames:v 1 -t 1 "$now"


  


  It produces an image through my FaceTime camera when I run the script manually in shell, as follows :

  


  $ /Users/mydir/Downloads/LIDOPRO/DailyScript.sh


  


  And the output I get is the following

  Everything works perfectly fine and the image is output.

  


  So, I created a cron job to run the script automatically, as follows :

  


  * * * * * /Users/caineardayfio/Downloads/LIDOPRO/DailyScript.sh 2> /tmp/error.txt 1> /tmp/output.txt


  


  However, this cronjob does not actually work. No photo is produced and the script seems to execute, but only partially :

  Does anyone know how to resolve this issue ? I'd like the image to be produced.
