Closed ccmoe closed 4 years ago

ccmoe commented 5 years ago

Hello， When I was ready for / TestVideo and test_videodatainfo.json, I received some errors at runtime.I tried to set the shell parameter value of the Popen function to True and run it, but I couldn't get the *.jpg file.I hope to get your help.The error appears as follows：

File "/***/preprocessing.py", line 121, in extract_features_msr_vtt extract_frames(video, dst) File "/***/caption-guided-saliency-master/preprocessing.py", line 101, in extract_frames subprocess.call(video_to_frames_command, stdout=ffmpeg_log, stderr=ffmpeg_log) File "/home/***/anaconda2/envs/python27/lib/python2.7/subprocess.py", line 168, in call return Popen(*popenargs, **kwargs).wait() File "/home/***/anaconda2/envs/python27/lib/python2.7/subprocess.py", line 390, in __init__ errread, errwrite) File "/home/***/anaconda2/envs/python27/lib/python2.7/subprocess.py", line 1024, in _execute_child raise child_exception OSError: [Errno 2] No such file or directory

Hi,

Does the file exist? Could you debug it to see which file is missing? E.g. the content of video_to_frames_command

@ramanishka ,This is the first time I use ffmpeg to extract frames. I don't know if I need to install some packages to use ffmpeg. After the function extract_frames() is executed successfully, (the above problem is not reported as wrong) the video frame cannot be obtained. I'm confused

@ccmoe In your previous message, you've mentioned "No such file or directory" error. Now you're saying that extract_frames() was executed successfully. Which one is correct?
