We've seen a case where an error from cuvid api is ending up in
an endless loop, creating a log file of > 10 GB like this:
[h264_cuvid @ 0xda1b40] ctx->cvdl->cuvidParseVideoData(ctx->cuparser, &cupkt)
failed -> CUDA_ERROR_UNKNOWN: unknown error
Error while decoding stream #0:0: Generic error in an external library
[h264_cuvid @ 0xda1b40] ctx->cvdl->cuvidParseVideoData(ctx->cuparser, &cupkt)
failed -> CUDA_ERROR_UNKNOWN: unknown error
Error while decoding stream #0:0: Generic error in an external library
[h264_cuvid @ 0xda1b40] ctx->cvdl->cuvidParseVideoData(ctx->cuparser, &cupkt)
failed -> CUDA_ERROR_UNKNOWN: unknown error
Error while decoding stream #0:0: Generic error in an external library
[h264_cuvid @ 0xda1b40] ctx->cvdl->cuvidParseVideoData(ctx->cuparser, &cupkt)
failed -> CUDA_ERROR_UNKNOWN: unknown error
This patch maps CUDA_ERROR_UNKNOWN to AVERROR_EXIT to make sure that
the application will stop.
