nvidia codec improve (#721)
* chore: lower the log level for vaapi/nvidia codec. * fix compile. * fix benchmark for libwebrtc m137. * Modify the Cuda Context singleton. * Avoid crashes caused by decoding failure. * Removed unnecessary null checks. * tidy. * fix. * check the cuda device count. * fix.
