  I'm trying to use FFMPEG to transcode a video with very large frames but I'm getting the following error when trying to convert 4k video on my server.

• FFmpeg freezes on the same frame and gets stuck on it

  12 juin 2020, par riles

  I'm trying to figure out why the following ffmpeg (4.2.1) command, which works well most of the time, sometimes ends up stuck on the same frame.

  



  This ffmpeg command allows me to make a LIVE streaming with recording VOD at the same time.

  



  Has anyone ever had this problem ?

  



  Thank you in advance for your help.

• ffmpeg is not capturing udp output

  30 octobre 2020, par Dzidas

  I'm trying to capture UDP output with ffmpeg, but the stream looks empty. Just for background, the output is produced by GoPro camera and I'm connecting to its Wifi. I can see with wireshark a lot of udp packets sent to my ip from GoPro IP, but nothing appears in ffmpeg.

  Any idea or suggestion how could I debug or understand the cause ?
