[FFmpeg-user] Asking for help

[Mohammed Bey Ahmed Khernache]

Hello,
I compiled ffmpeg without encoders (--disable-encoders). Then, when I try
to decode a video bit-stream, I get this error message:
"Automatic encoder selection failed for output stream #0:0. Default encoder
for format null (codec wrapped avframe) is probably disabled. Please choose
an encoder manually. Error selecting an encoder for stream 0:0".

The command I used is the following:
ffmpeg -i input.h265 -f null /dev/null

Could someone explain to me why this happened?

Best regards
