I already have that code
if (flv_frmtctx->oformat->flags & AVFMT_GLOBALHEADER) {
h264_codec_ctx->flags |= AV_CODEC_FLAG_GLOBAL_HEADER;}
Keep the ideas coming
Thanks

Have you confirmed that the H.264 stream produced by the hardware encoder can
actually be decoded by Youtube? Some of these hardware encoders use
non-standard/less-common options that might cause problems with a streaming
service. Since you're using "-vcodec copy" you're essentially just passing
through the NAL stream from the hardware encoder unmodified.
I would suggest trying it with an H.264 stream that isn't the output of the
hardware encoder, just to see if this is really a problem with the RTMP as
opposed to the H.264 stream contained within it.

Hi all,
My guess is that your header information is not properly set. This will cause
YouTube or Twitch to not decode the stream. Twitch has much better tools to
diagnose these kinds of problems.
Make sure that you have this code before you call the avcodec_open2:
if (oc->ofmt_ctx->oformat->flags & AVFMT_GLOBALHEADER){
enc_ctx->flags |= AV_CODEC_FLAG_GLOBAL_HEADER;
}
