I am trying to use ffmpeg source code top encode video streams in linux. I used the code provided in this link https://ffmpeg.org/doxygen/3.2/muxing_8c_source.html to encode videos.
I got an error, when the code accessed the function ret = avcodec_open2<https://ffmpeg.org/doxygen/3.2/group__lavc__core.html#ga11f785a188d7d9df71621001465b0f1d>(c, codec, &opt);
[h264_v4l2m2m @ 0x114ac00] Could not find a valid device
[h264_v4l2m2m @ 0x114ac00] can't configure encoder
May I know, why I get this error and how I could solve this?
