• avformat_open_input failed at openning local rtmp stream

  3 septembre 2019, par edhu

  I’m relatively new to this workflow and this might be a simple problem to solve. However, I haven’t found answers that matched exactly with my question. I’ve set up my nginx server with rtmp module and for testing purposes I used the following command to publish my stream :

  ffmpeg -re -i  -vcodec libx264 -vprofile baseline -acodec aac -strict -2 -f flv rtmp://localhost/show/stream

  After that, I launched up my application which is supposed to read the stream from the nginx server and it failed at

  avformat_open_input(&ctx, szFilePath, NULL, NULL);

  The returned error code is -5 and it signifies I/O issue. The szFilePath I passed in is rtmp://localhost/show/stream and I assume this will automatically work since it works when I tried to play some mp4 sample files online. I also tried rtmp://localhost:1935/show/stream and vice versa. I could view the stream being played in VLC but I can’t open it in the code. I’m not really sure what happened here. I feel like this isn’t necessarily a complicated issue but I don’t know where to start looking for possibles causes. I’d appreciate the help. Thanks !

  Android.mk :

  And i get an error :

  clang++ : error : linker command failed with exit code 1 (use -v to see invocation)

  make : *** [obj/local/arm64-v8a/libffmpeg_main.so] Error 1

  What should i do ?Who can help me.

  Ouep, c’était sur spip-zone https://www.mail-archive.com/spip-zone@rezo.net/msg49170.html et la proposition que j’y faisais est restée sans réponse...

  je propose :
  
   de fixer rapidement en patchant purger_repertoire()
  
   puis d’améliorer action_purger_dist() à tête reposée, après avoir dressé la liste des répertoires à cibler (cf mon mail précédent)
  Comme ça, ceinture, bretelles et rapidité du fix :)
  

  Pour la rapidité du fix on repassera :p
