If it works with youtube-dl, it actually is not really an issue with youtube-dl, maybe?
Ever thought about that?

[Solr007]

the problem is about the block of the subprocess .

[siddht4]

usually the output is retrieved when the python / youtube-dl process ends . so the error here is that you are not patience , if its more than a 500 mb of file it will take its own time , just give it that much time to work

[siddht4]

think it this way java ------> jvm ----> exec python -----> youtube-dl (python ) -----> ffmpeg (if required) ---> exec python ends ------> back to jvm ------> java i.e your code
