avformat_open_input returns -2 (Android)
13 octobre 2020, par IveliusI'm using this FFMPEG port for Android.
My Goal is to read RTSP stream eventually.



I can open a stream from a local file (located at "/storage/emulated/0/bunny.mp4") ,
using *avformat_open_input* function.



However when I try to open the same file from remote location like *"http_ ://192.168.1.183/bunny.mp4*" , it returns error -2 .



The whole cpp code is here.



Any ideas ?

Stream MP4 over HTTP without segments
23 novembre 2017, par Ben van HartingsveldtI’m trying to stream MP4.
If you stream MP3, you can stream it to something (maybe via RTMP or via IceCast) and watch it via HTTP (but no HLS). Your live MP3 file is something like : http://example.com/live.mp3. Here you can listen to live generated MP3.
Now I want something simular with MP4.
I want to stream MP4 (AVC/H.264) to a server (maybe via RTMP) and want to receive the livestream on this location : http://example.com/live.mp4.
I don’t want to use HLS (with it’s M3U8 file and TS-files).Is this possible ?
I know it works with a already generated MP4, after you converted it to a FastStart/WebOptimised MP4, but I want a LIVE mp4.
