Why does an "ffmpeg fail" occur when trying to export frames from my "data_src.mp4" file, while using DeepFaceLab ?
28 août 2020, par Toby RybergI've been following this step-by-step videoin installing and using DeepFaceLab on my Macbook Pro, which uses OS Catalina. I've been stuck at the step which begins at the 4:42 mark, where he enters this code :


python main.py videoed extract-video —input-file WORKSPACE/data_src.mp4 —output-dir WORKSPACE/data_src


After entering the command, I'm prompted to enter an FPS value ; no problem. Next, it asks for a file output type, which is where I get tied up— as far as I know. It appears as though I can enter either png or jpeg, but receive the same error message, which looks like this :


/ !\ ffmpeg fail, job commandline :['ffmpeg', '-i', '/Users/tobyryberg/Documents/deepfakes/DeepFaceLab/WORKSPACE/data_src.mp4', '-pix_fmt', 'rgb24', '/Users/tobyryberg/Documents/deepfakes/DeepFaceLab/WORKSPACE/data_src/%5d.png']


I have no idea what went wrong, as I BELIEVE that I have been doing everything right thus far. If this is at all necessary information, I've opted to use an 18+ minute long video for my source clip, which is an .mp4 file, without audio. If there's someone out there who has the patience to work with me and figure out what went wrong, I'll be forever grateful !

i want to stream the audio to "cast" dose this protocol have a more specific name ? its the one that Spotify and YouTube can send audio video to over local network ; little screen with a wifi signal in the bottom left corner.


i am thinking of going into ffmpeg or vlc to stream from usb to some cast program, dose anyone have any suggestions on where to start any key words so im not blindly googling ?
sorry this is so open ended, ill mark it solved with the best answer in like 5 days or when i finish this project ( turntable -> usb audio capture card on pi -> steam to cast protocol -> wifi speakers )

Opencv Won't compile due to "cap_ffmpeg_impl.hpp" and "ffmpeg_codecs.hpp"
13 octobre 2022, par AmberGraph41161I am new to opencv and linux. I am trying to install opencv or build opencv from source to use the library with c++. When building or trying to use "make" to build all the files, everything is fine until around 50% (I've tried to redo the entire installation process multiple times over because I have no idea what I am doing and keep getting the same errors). At around the 50% mark, I get the same two errors :


make[2]: *** [modules/videoio/CMakeFiles/opencv_videoio.dir/build.make:244: modules/videoio/CMakeFiles/opencv_videoio.dir/src/cap_ffmpeg.cpp.o] Error 1
make[1]: *** [CMakeFiles/Makefile2:5218: modules/videoio/CMakeFiles/opencv_videoio.dir/all] Error 2
make: *** [Makefile:166: all] Error 2


I get these two errors as well as a ton of build error messages containing errors about 2 files in particular (I get a bunch of errors and all of them deal with 2 files).


/home/jinwoo_k/opencv/opencv-4.6.0/modules/videoio/src/ffmpeg_codecs.hpp:96:27: error: ‘CODEC_ID_LJPEG’ was not declared in this scope; did you mean ‘AV_CODEC_ID_LJPEG’?

 100 | #define AV_CODEC_ID_RAWVIDEO CODEC_ID_RAWVIDEO
 | ^~~~~~~~~~~~~~~~~



^^^These are just a couple of the error messages, I get hundreds of them.


I read another stackoverflow post about opencv and ffmpeg : OpenCV 3.0.0 make error with FFMPEG
but I don't think that this is the same error that I have. I don't believe that I have made a mistake in the installation or build process or anything with cmake - I have followed and redone the process of following mutliple video and forum guides on how to install opencv. What am I doing wrong ?
