 Now the installation is done we can do a test (https://tecadmin.net/install-ffmpeg-on-centos/#)

 ==== Using FFPROBE ====
+We are going to join a stream to read the stream characteristics, use the following syntax.
+\\
+    ffprobe udp://239.0.200.1:10001
+\\
+If you successfully join the stream you will get an output similar to the following example.
+\\
+<file>
+Input #0, mpegts, from 'udp://239.0.200.1:10001':
+  Duration: N/A, start: 5793.912200, bitrate: 128 kb/s
+  Program 1
+    Metadata:
+      service_name    : VSPP ABR Test
+      service_provider: Ericsson
+    Stream #0:0[0x3e9]: Video: h264 (Main) ([27][0][0][0] / 0x001B), yuv420p, 1920x1080 [SAR 1:1 DAR 16:9], 25 tbr, 90k tbn, 180k tbc
+    Stream #0:1[0x7d1]: Audio: aac ([15][0][0][0] / 0x000F), 48000 Hz, stereo, fltp, 128 kb/s

+When you start ffprobe, you will likely see some errors, I am not sure what this is, but it could be errors that are generated until the first I frame is found.
